Top Tips: Eating for Healthy Skin

We often think of skincare as something that happens in the bathroom. We cleanse, moisturise, exfoliate and apply sunscreen, yet the skin is also maintained from within throughout the day.

Skin cells need energy and nutrients. Collagen formation requires amino acids and vitamin C. The skin barrier contains fats that help limit water loss, while antioxidant defence systems rely on nutrients obtained through the diet.

This does not mean that one food will clear acne, cure eczema or remove wrinkles. Skin health is influenced by hormones, genetics, immune function, medication, sun exposure, stress and skincare, as well as nutrition. However, food provides many of the raw materials needed for normal skin structure and maintenance. A varied diet containing adequate protein, healthy fats and plenty of colourful plants is likely to offer more meaningful support than chasing the latest so-called superfood.

Here are my top tips for eating for healthy skin.

1. Eat the Rainbow, but Understand Why

“Eat the rainbow” can sound like vague nutrition advice, but the colours in plant foods often represent different families of naturally occurring compounds.

Tomatoes and watermelon contain lycopene. Carrots, squash and sweet potatoes provide beta-carotene. Dark leafy vegetables contain lutein and beta-carotene, while berries, red cabbage and blackcurrants contain anthocyanins. Many of these compounds interact with the body’s antioxidant defence systems.

Your body naturally produces reactive molecules during metabolism, energy production and immune defence. Oxidative stress occurs when the production of these molecules exceeds the body’s capacity to manage them.

Within the skin, ultraviolet radiation, pollution and cigarette smoke can add to this burden. Excessive oxidative stress may damage cell membranes, proteins and DNA. It can also activate inflammatory pathways and enzymes involved in breaking down collagen and other components of the skin’s supporting structure.

The aim is not to eliminate oxidation. Reactive molecules also perform useful biological roles. Instead, the goal is to provide the nutrients the body uses within its own defence and repair systems.

Regularly include a mixture of berries, cherries, plums, blackcurrants, tomatoes, peppers, watermelon, carrots, pumpkin, sweet potato, broccoli, watercress, leafy greens, red cabbage, beetroot and aubergine. Herbs, spices, tea, coffee and cocoa also contribute useful plant compounds.

You do not need every colour at every meal. Aim to eat several colours across the day and vary them throughout the week.

2. Include Vitamin C-Rich Foods Every Day

Vitamin C is one of the nutrients most directly involved in normal skin structure. It contributes to normal collagen formation for the normal function of skin and also contributes to the protection of cells from oxidative stress.

Collagen begins as chains of amino acids. Before these chains can become strong, stable collagen fibres, they must undergo several chemical modifications. Vitamin C acts as a cofactor for enzymes involved in this process. In simpler terms, protein provides the building materials, while vitamin C helps the body assemble them into normal collagen.

Useful sources include red and yellow peppers, blackcurrants, strawberries, kiwi fruit, citrus fruit, broccoli, Brussels sprouts, watercress, leafy greens, tomatoes and new potatoes. Vitamin C is water-soluble and can be reduced by prolonged cooking, so include a mixture of raw and lightly cooked produce where possible.

3. Do Not Forget Protein

Collagen is a protein, and normal tissue maintenance depends on an adequate supply of amino acids. This does not mean that eating collagen sends it directly to the face. Dietary proteins are broken down into amino acids and small peptides, which the body then uses for muscles, enzymes, immune proteins, connective tissue and skin.

Protein intake is often uneven. Breakfast may consist mainly of toast or cereal, lunch can be light, and most of the day’s protein is left until dinner. Including a meaningful protein source at each meal makes it easier to meet overall requirements.

Good options include eggs, fish and seafood, poultry, lean meat, Greek yoghurt, cottage cheese, kefir, tofu, tempeh, edamame, beans, lentils and chickpeas.

Plant-based diets can provide the amino acids required for the body’s own collagen production. Plants do not contain collagen, but this does not mean animal collagen must be eaten.

The important factors are sufficient total protein, enough energy, dietary variety and an adequate intake of vitamin C.

4. Make Polyphenols Part of Ordinary Meals

Polyphenols are a large family of plant compounds found in vegetables, fruit, tea, coffee, cocoa, herbs, spices, nuts, seeds and extra virgin olive oil.

Laboratory studies suggest that some polyphenols interact with antioxidant defence, inflammatory signalling and enzymes involved in collagen breakdown. Human evidence is more variable because polyphenols are extensively digested and metabolised.

Their effects also depend on the food, the amount consumed, the gut microbiome and the wider dietary pattern.

This means it is more sensible to eat a wide range of polyphenol-rich foods than to expect one ingredient to transform the skin.

Easy ways to increase them include adding berries, cherries or chopped apple to breakfast, using extra virgin olive oil on salads and vegetables, adding herbs and spices generously to meals, drinking green or black tea, choosing red onion, red cabbage and aubergine, and adding natural cocoa to yoghurt or porridge.

Cocoa is an interesting example. Some small controlled studies using specially standardised high-flavanol cocoa products have reported changes in skin blood flow, elasticity or responses to UV exposure.

These products are not the same as an ordinary chocolate bar, so the research does not mean unlimited chocolate becomes a skincare strategy, unfortunately. A couple of squares of dark chocolate can, however, be enjoyed as part of a balanced diet.

5. Include Omega-3 Fats Regularly

Fats are sometimes overlooked in conversations about skin, yet the skin barrier contains a complex mixture of lipids that helps restrict excessive water loss and protect against the external environment.

Omega-3 fatty acids are also used to produce signalling molecules involved in regulating inflammatory responses. The most biologically active omega-3 fats are EPA and DHA, found mainly in oily fish such as salmon, sardines, mackerel, trout, herring and anchovies. UK guidance recommends eating at least two portions of fish each week, including one portion of oily fish, although maximum recommended intakes differ for certain groups.

Walnuts, chia seeds, hemp seeds and ground flaxseed provide the plant omega-3 fat alpha-linolenic acid, or ALA. The body can convert some ALA into EPA and DHA, but the conversion is limited. These foods remain valuable sources of fibre, minerals and unsaturated fats, although they are not nutritionally identical to oily fish. People who do not eat fish may wish to use omega-3-fortified foods or discuss an algae-derived EPA and DHA supplement with a suitably qualified professional.

Research into omega-3 fats and individual skin conditions remains mixed, so oily fish should not be presented as a treatment for acne, eczema or rosacea. It can, however, form part of a balanced dietary pattern that provides fats needed for cell membranes and normal inflammatory regulation.

6. Use Extra Virgin Olive Oil as a Daily Staple

Extra virgin olive oil is more than simply a source of monounsaturated fat. It also provides phenolic compounds that distinguish it from more heavily refined oils. It is a central part of the traditional Mediterranean diet, alongside vegetables, fruit, beans, lentils, wholegrains, nuts, seeds, herbs and fish.

Research has associated Mediterranean-style dietary patterns with better cardiometabolic health and more favourable markers of inflammation and oxidative stress. Direct evidence relating specifically to skin appearance is less extensive, so it should not be promoted as a wrinkle-reducing diet.

Its value is that it brings together many nutrients involved in normal skin maintenance, including vitamin C, carotenoids, polyphenols, omega-3 fats, protein, vitamin E, zinc and selenium.

Use extra virgin olive oil as a salad dressing, drizzle it over cooked vegetables or add it to beans, soups and wholegrains.

It can also be used for normal home cooking. There is no need to save it exclusively for cold dishes, although repeatedly overheating any oil should be avoided.

Food cannot promise flawless or ageless skin. What it can do is provide nutrients involved in normal collagen formation, antioxidant protection, tissue maintenance and the function of the skin barrier.

Persistent acne, eczema, unexplained rashes, non-healing areas or changes to a mole should be assessed by a GP, pharmacist or dermatologist. Nutritional support can complement appropriate care but should not replace medical diagnosis or treatment.

Skin Health from Within

We spend a great deal of money trying to improve our skin from the outside. Serums, masks and moisturisers can all have their place, but the skin is not simply a covering. It is a living organ that needs energy, protein, fats, vitamins and minerals for everyday maintenance and repair.

What you eat cannot stop ageing, replace sunscreen or cure a skin condition. However, nutrition provides the raw materials used to form collagen, maintain the skin barrier and support antioxidant defence.

Why Skin Reflects Internal Health

The skin is one of the body’s first lines of defence. Its outer layer helps reduce water loss and protects against irritants, microbes, pollution and physical damage. Beneath it sits the dermis, which contains blood vessels, glands and the extracellular matrix that gives skin much of its strength and flexibility.

Collagen and elastin are important components of this structure. Collagen provides strength, while elastin allows the skin to stretch and return towards its original shape. Fibroblasts continually produce and remodel these proteins.

This process changes with age. Collagen production gradually declines and existing fibres become less well organised. Menopause can accelerate these changes because oestrogen influences skin thickness, hydration and collagen metabolism.

Age is not the only influence. Ultraviolet radiation, smoking, air pollution, poor sleep and persistent stress can all increase oxidative stress or inflammatory signalling. These processes may activate enzymes known as matrix metalloproteinases, or MMPs, which break down parts of the skin’s supporting matrix, including collagen. This helps explain why two people of the same age may have very different skin. Genetics matter, but so does the environment in which the skin has been living.

Nutrition is one part of that environment. It should be viewed as additional support, not edible SPF. Shade, protective clothing and an appropriate broad-spectrum sunscreen remain essential.

There is also growing interest in the gut–skin axis. Gut microbes produce metabolites that interact with the immune system, intestinal barrier and inflammatory pathways. Researchers are investigating these connections in relation to acne, eczema, psoriasis and rosacea. This does not mean every skin flare begins in the bowel. Skin conditions usually have several contributing factors, and microbiome research is still developing. However, it reinforces the idea that skin health does not exist separately from digestion, immune regulation and the quality of the overall diet.

Nutrients That Support Collagen and Skin Structure

No single “beauty food” can transform the skin. Collagen formation is a multi-stage process that depends on enough energy, amino acids, vitamin C and several supporting micronutrients.

Vitamin C has a particularly direct role. It contributes to normal collagen formation for the normal function of skin and contributes to the protection of cells from oxidative stress.

Collagen begins as chains of amino acids. These chains must undergo several chemical modifications before they can form strong fibres. Vitamin C acts as a cofactor for enzymes involved in this process.

Good food sources include peppers, blackcurrants, strawberries, kiwi fruit, citrus fruit, broccoli, Brussels sprouts, watercress, tomatoes and new potatoes.

Vitamin C is water-soluble and sensitive to prolonged cooking, so include a mixture of raw and lightly cooked produce. There is no need for enormous doses. Regular intake from food is more useful than occasionally consuming a very large amount.

Protein supplies the amino acids used to build and repair tissues. Collagen contains high amounts of glycine and proline, but eating collagen does not send it directly to the face. Dietary proteins are broken down, and their amino acids are used according to the body’s priorities.

Include a useful protein source at each main meal. This might be fish, eggs, poultry, lean meat, Greek yoghurt, tofu, tempeh, beans, chickpeas or lentils. Plant-based diets can provide the amino acids needed for the body’s own collagen production. Plants do not contain collagen, but they provide protein alongside vitamin C, polyphenols and other nutrients involved in normal tissue maintenance.

Polyphenols are plant compounds found in berries, cherries, grapes, cocoa, tea, herbs, spices, olives and colourful vegetables.

Laboratory research suggests that some polyphenols can interact with antioxidant defence, inflammatory signalling and enzymes involved in collagen breakdown. Human research is more variable because polyphenols are extensively digested and metabolised.

It therefore makes more sense to eat a wide range of polyphenol-rich foods than to expect one ingredient to reverse skin ageing. Easy additions include berries at breakfast, extra virgin olive oil on vegetables, herbs and spices in cooking, green or black tea, red cabbage, aubergine, apples and a small amount of high-cocoa dark chocolate.

Oxidative Stress and Premature Ageing

Oxidative stress occurs when the production of reactive molecules exceeds the body’s ability to manage them. Reactive oxygen species are not automatically harmful. They are produced during normal metabolism and participate in immune defence and cell signalling. Problems arise when production becomes excessive or antioxidant defences are inadequate.

Ultraviolet radiation is a major external driver of oxidative stress in the skin. Pollution and cigarette smoke can add to this burden. Excessive oxidative stress can affect DNA, cell membranes and proteins, and can activate inflammatory pathways and collagen-degrading enzymes.

The body has its own antioxidant network involving enzymes and nutrients such as vitamin C, vitamin E, selenium, zinc and carotenoids. These do not form an invisible shield. They work as part of a coordinated defence and repair system.

Carotenoids are the yellow, orange and red pigments found in carrots, tomatoes, peppers, pumpkin, watermelon and leafy greens. Several can accumulate in the skin. Human feeding studies suggest that regularly eating carotenoid-rich foods may modestly increase resistance to UV-induced redness. This effect develops gradually and is far weaker than sunscreen or protective clothing.

Oxidative stress can also be generated internally. Persistently high blood glucose may increase oxidative stress and promote the formation of advanced glycation end-products, or AGEs. Glycation occurs when sugars react with proteins. When this affects long-lived proteins such as collagen, fibres may become stiffer and more resistant to normal repair. This does not mean sugar must be eliminated or that one pudding ages the face. The repeated metabolic environment matters more than a single food.

Meals built around protein, vegetables, fibre-rich carbohydrates and healthy fats generally produce a steadier glucose response than meals dominated by refined carbohydrates.

Everyday Foods for Healthier Skin

A skin-supportive diet does not require specialist powders or a restrictive “cleanse”. It looks much like a varied Mediterranean-style pattern.

Aim to include:

• A protein source at each meal
• Vitamin C-rich fruit or vegetables every day
• A range of colourful plant foods across the week
• Extra virgin olive oil, nuts, seeds and avocado
• Oily fish regularly, within UK guidance
• Fibre-rich foods such as oats, beans, lentils and wholegrains

Eat enough overall. Chronic under-eating can reduce intake of protein, essential fats and micronutrients. Look after the gut by increasing plant diversity gradually and according to tolerance. Fermented foods may suit some people but are not compulsory.

Drink regularly, but remember that litres of water will not erase dry skin or wrinkles. Limit smoking and excessive alcohol, prioritise sleep and seek medical advice for persistent acne, eczema, unexplained rashes or changes to a mole.

Healthy skin is not created by one perfect meal, and it is not ruined by one imperfect one.

Top Tips: Travel-Friendly Food Swaps for a Healthy Gut

Travel food can be a bit of a lottery. Sometimes you find a lovely little café with fresh food, proper coffee and plenty of delicious options that you can photograph and remember when you get home. Other times, you are standing in an airport queue, tired, hungry and wondering whether lunch is going to be a packet of crisps, a giant muffin or a slightly limp sandwich.

When you have a sensitive gut, this can feel even more difficult. You may be trying to avoid bloating, reflux, constipation, loose stools or blood sugar dips, but you also do not want to turn your holiday into a set of food rules.

The good news is that supporting your gut while travelling does not have to mean packing a suitcase full of chia seeds or refusing every ice cream, pastry or restaurant meal. It is usually about making a few simple swaps that help keep your digestion, energy and appetite steadier.

Think of this as adding a little structure around the edges, so you can enjoy your time away without your gut feeling completely abandoned.

Why Travel Often Disrupts Digestion

Your gut is surprisingly sensitive to routine.

At home, you may eat at fairly similar times, drink from your usual mug, have access to foods you know you tolerate, and move around in a way your body recognises. When you travel, that rhythm changes quickly.

You may skip breakfast to get to the airport, drink more coffee than usual, sit still for hours, snack instead of eating a proper meal, eat later at night, drink less water and have a bit more alcohol, or rely on foods that are lower in fibre and protein. None of this is “bad”, but it can make digestion feel more unpredictable.

For some people, travel leads to constipation because they are moving less, drinking less and ignoring the urge to go. For others, the combination of rich food, alcohol, unfamiliar ingredients, stress and disrupted sleep can trigger bloating, reflux or loose stools.

If you have IBS, this can be even more noticeable. IBS symptoms can be affected by meal timing, stress, caffeine, alcohol, fizzy drinks, fibre type, fat content and individual food triggers. This is why a travel day that looks “not that bad” on paper can still leave you feeling uncomfortable.

The aim is not to eat perfectly. It is to make a few swaps that reduce the overall digestive load.

Practical Swaps for Airports, Hotels and Road Trips

One of the easiest ways to support your gut when travelling is to avoid going into the day underfed and over-caffeinated.

A common travel pattern is coffee at home, coffee at the station, something sweet at the airport, then a long gap before a very large meal. This can leave you tired, wired, bloated and craving more quick energy by the afternoon.

A better swap is to aim for protein earlier in the day. If you are at the airport, look for eggs, Greek yoghurt, smoked salmon, chicken, hummus, cheese, nuts, seeds or a more substantial sandwich or salad with protein. 

If you are leaving early, even a quick breakfast at home can help: yoghurt with berries and seeds, eggs on toast, overnight oats with protein, or a smoothie with protein powder if you tolerate it.

If your usual travel choice is a pastry or muffin, you do not need to ban it. But you may feel better if you pair it with something more sustaining. For example, have a croissant with Greek yoghurt or eggs rather than on its own. Have fruit with nuts rather than fruit alone. Choose a sandwich with chicken, tuna, egg or hummus instead of a plain cheese baguette with very little fibre or colour.

At hotel breakfasts, the same principle applies. Start with protein, then add plants and carbohydrates you tolerate. Eggs with tomatoes and mushrooms, yoghurt with berries and seeds, porridge with ground flaxseed, or smoked salmon with sourdough may all be more supportive than a plate made entirely of pastries, juice and coffee.

For road trips, the biggest issue is often convenience food. Service stations are improving, but they still make it very easy to graze on crisps, sweets, chocolate bars and fizzy drinks. These foods are not forbidden, but if they become the whole meal, your gut and energy may not thank you.

A simple road trip swap is to pack one “proper food” option before you leave. That might be a chicken wrap, oatcakes with cheese, a boiled egg pot, hummus with crackers, leftover frittata, yoghurt with berries, or a small cool bag with fruit, nuts and a protein option. You can still stop for coffee or enjoy something fun, but you are not relying entirely on what is available next to the petrol pumps.

Protein and Fibre on the Go

Protein and fibre are two of the most useful travel nutrition anchors.

Protein helps meals feel more satisfying and supports steadier energy. Fibre supports bowel regularity, gut microbiome diversity and stool consistency, although the type and amount of fibre matters if you have IBS or bloating.

The problem is that many travel foods are high in refined carbohydrates but low in protein and fibre. Think pastries, muffins, crisps, sweets, white bread sandwiches, biscuits and sugary drinks. These can be convenient, but they may leave you hungry again quickly or more prone to energy dips. A better approach is to build a “protein plus fibre” habit.

Instead of crisps on their own, try oatcakes with cheese, hummus with crackers, roasted chickpeas if you tolerate legumes, or nuts with fruit.

Instead of a sweet cereal bar, try a simple protein bar with recognisable ingredients, Greek yoghurt with berries, or a small bag of trail mix.

Instead of a white bread sandwich with very little filling, choose one with chicken, tuna, egg, smoked salmon, falafel or hummus, ideally with salad or vegetables.

Instead of fruit juice, choose whole fruit and water. Whole fruit provides fibre and tends to be more filling than juice, which can deliver a lot of sugar quickly and may loosen stools in some people.

If you are prone to bloating, be mindful that more fibre is not always better on a travel day. Suddenly eating lots of raw vegetables, beans, bran bars or dried fruit can make symptoms worse. Soluble fibre is often gentler. Oats, chia, ground flaxseed, berries, peeled fruit, potatoes and carrots may suit some people better than large raw salads or high-bran products.

Smarter Snack Choices for Energy
Snacks can be really useful when travelling, especially if meals are unpredictable. The issue is not snacking itself. The issue is relying on snacks that give you a quick lift, then leave you hungrier, more tired or more bloated an hour later.

A good travel snack usually has at least one of three things: protein, fibre or healthy fats. Even better if it has two.

Some practical options include oatcakes with nut butter, rice cakes with cheese, nuts and fruit, Greek yoghurt, boiled eggs, hummus with crackers, roasted edamame if tolerated, a simple protein bar, biltong, olives, avocado pots, or a small homemade flapjack with oats and seeds.

It is also worth watching the “health halo” snacks. Many bars, protein snacks, vegetable crisps and gluten-free travel foods are marketed as healthy, but may be high in sugar, sweeteners, emulsifiers, polyols or additives that do not suit a sensitive gut. Some sugar-free sweets and bars contain sugar alcohols such as sorbitol, xylitol or maltitol, which can trigger gas, bloating or diarrhoea in people with IBS.

A simple label check can help. Look for a shorter ingredient list, a decent protein or fibre content, and ingredients you recognise. If a product has a long list of syrups, sweeteners, gums, flavourings and claims on the front of the packet, it may not be as gut-friendly as it looks.

Preparing Ahead Without Obsessing
A little planning can make travel much easier, but there is a fine line between being prepared and becoming anxious about food.

The aim is not to pack every meal or avoid all local food. One of the joys of travel is eating differently. But if your gut is sensitive, it can help to take a few familiar options with you, so you are not completely dependent on airports, service stations or hotel buffets.

Before you travel, think about your likely pinch points. Is it the early start? The airport wait? The long car journey? The hotel breakfast? The late dinner? The moment when everyone else wants cocktails and crisps but you have not eaten properly since 10am?

Once you know your weak spot, you can plan around it.

For an early start, prepare breakfast the night before. For a long journey, pack a protein-rich snack and water. For a hotel breakfast, decide in advance that you will start with protein. For a day trip, take something familiar in your bag. For a hot day, keep hydration and electrolytes in mind.

If you are travelling with IBS, SIBO-type symptoms, reflux or a very sensitive gut, it may also help to keep your food choices simpler for the first day or two. Give your body time to adjust before you add in all the rich food, alcohol, late nights and new ingredients at once.

You can still enjoy your holiday. You may just enjoy it more if your gut is not in crisis by day three.

And if your gut is making going away a worry, it doesn’t have to be that way. Why not book in a call to find out more?

Portable Protein Snack – Savoury Oatcakes with Seeds

Travel snacks can be tricky. Many of the easiest options are either very sweet, very beige, very low in protein, or full of ingredients that you can’t pronounce. You might start the journey with good intentions, then find yourself relying on crisps, pastries, cereal bars, sweets or another round of coffee because there is very little else available.

There is nothing wrong with enjoying convenience foods sometimes. But if you are travelling, working long days, driving, flying or heading out for a summer day trip, having one or two reliable snacks with you can make a real difference to your energy, appetite and digestion.

These savoury oatcakes are designed to be portable, practical and satisfying. They combine oats, seeds, chickpea or buckwheat flour, herbs and olive oil to create a fibre-rich snack that pairs well with protein toppings such as cottage cheese, hummus, boiled eggs, smoked salmon, chicken, tuna or nut butter.

They are not a replacement for meals, but they are a useful “back-up” option when you need something more substantial than a sweet snack bar.

Why Protein and Fibre Matter While Travelling

When you are away from home, it is very easy for meals and snacks to become low in protein and fibre.

That might look like toast and jam for breakfast, a pastry at the station, crisps in the car, a muffin at the airport, or a sandwich with very little filling. These foods may be convenient, but they do not always keep you full for long, and they may contribute to energy dips, cravings or digestive sluggishness later in the day.

Protein helps meals and snacks feel more satisfying. It also supports muscle maintenance and many normal body functions. Fibre supports digestive regularity, stool consistency and the gut microbiome. 

Oats are a particularly useful travel food because they are portable, versatile and contain beta-glucan, a type of soluble fibre. Seeds add extra fibre, minerals and healthy fats, while chickpea flour adds more protein and structure. If you are very sensitive to legumes, you can use buckwheat flour instead, which tends to be better tolerated by some people.

As always, tolerance matters. A food can be nutritious and still not suit every gut. If you are prone to bloating, start with a small portion and pair the oatcakes with foods you already know you tolerate.

This recipe makes approximately 14–16 oatcakes, depending on size and thickness.

Ingredients

150g gluten-free rolled oats
60g chickpea flour or buckwheat flour
40g pumpkin seeds, roughly chopped
30g hemp seeds
20g ground flaxseed or chia seeds
20g nutritional yeast, optional but adds savoury flavour
1 teaspoon GF baking powder
½ teaspoon sea salt
1 teaspoon dried rosemary, thyme or mixed herbs
½ teaspoon garlic granules, optional
½ teaspoon smoked paprika, optional
2 tablespoons extra virgin olive oil
120–150ml warm water
Optional: 1 tablespoon sesame seeds for the top

Method

• Preheat the oven to 180°C fan and line a baking tray with baking parchment.
• Add the oats, flour, pumpkin seeds, hemp seeds, ground flaxseed or chia, nutritional yeast, baking powder, salt and herbs to a mixing bowl. Stir well so the seeds and seasoning are evenly distributed.
• Add the olive oil and 120ml warm water, then mix until a firm dough starts to form. Leave it to sit for 5 minutes so the oats and seeds can absorb the liquid. If the mixture feels too dry or crumbly, add a little more water, one tablespoon at a time. You want a dough that holds together but is not sticky.
• Place the dough between two sheets of baking parchment and roll it out to around 4–5mm thick. The thinner you roll it, the crisper the oatcakes will be. Cut into rounds, squares or rectangles using a cutter or knife.
• Transfer to the baking tray and sprinkle with sesame seeds if using. Bake for 18–22 minutes, turning the tray halfway through. They should be lightly golden and firm to the touch.
• Allow to cool fully on a wire rack. They will crisp up more as they cool.
• Enjoy!

Storage and Batch Cooking Tips

These oatcakes are ideal for batch cooking because they store well and are easy to pack.

Once completely cool, keep them in an airtight container for up to 5 days. If you want them to stay crisp, make sure they are fully cooled before storing. You can also freeze them for up to 3 months. Freeze in small portions, then defrost as needed.

For travel, pack them in a small container rather than a bag so they do not crumble in your handbag, rucksack or hand luggage.

You can also vary the flavour depending on what you enjoy. Rosemary and sea salt works well with cheese or hummus. Smoked paprika pairs nicely with avocado or chicken. Thyme and sesame seeds are lovely with cottage cheese or smoked salmon. If you prefer a plainer oatcake, leave out the stronger spices and keep the flavour simple.

Travel-Friendly Serving Ideas

The oatcakes are useful on their own, but they work best when paired with protein or healthy fats.

Try them with cottage cheese and cucumber, hummus and grated carrot, boiled eggs, smoked salmon and avocado, tuna with olive oil and lemon, chicken slices, nut butter, or a small pot of Greek yoghurt on the side.

For a road trip, pack oatcakes with a small pot of hummus, cheese, fruit and a bottle of water. For a flight, pair them with a protein option bought at the airport, such as boiled eggs, yoghurt, chicken salad or smoked salmon. For a hotel room snack, keep them with nut butter sachets, fruit or a small portion of nuts.

They can also be used as part of a light lunch. Add them to a plate with soup, salad, leftover frittata, roasted vegetables, tinned fish, avocado or a protein-rich dip.

Electrolytes, Hydration and Energy

If you often find that your energy dips during the summer months, it can be easy to assume it’s just because you are busy, tired from the heat or not sleeping well. And, yes of course, those things could be part of the picture. But there may be another basic factor that you have missed: hydration.

In warmer weather, during travel, after exercise, or on days when you are rushing around and drinking less than usual, your fluid and electrolyte balance can shift. This can leave you feeling tired, headachy, light-headed, sluggish, constipated, foggy or even more prone to cravings.

It’s good to note that hydration is not just about drinking lots of plain water. Your body also relies on electrolytes, these are minerals such as sodium, potassium, magnesium, calcium and chloride, to help regulate fluid balance, nerve signalling, muscle function and normal cellular processes.

That doesn’t mean everyone needs to be popping expensive electrolyte powders every day. For most of us, the best place to start is much simpler: regular fluids, water-rich foods, balanced meals and a little more attention to salt and minerals when the weather is hot, you are sweating more, travelling, exercising (or losing fluid through diarrhoea or vomiting!).

Why Hydration Affects Energy and Digestion

Water is involved in almost every system in the body. It helps regulate body temperature, supports circulation, carries nutrients, helps remove waste products, supports concentration and helps keep the digestive system moving.

So when your fluid intake drops, your body has to work much harder. Blood volume may reduce slightly, which can contribute to feeling light-headed, tired or less able to concentrate. Your mouth may feel dry, your urine may become darker, and you may notice headaches or a general sense of feeling below par.

Digestion can also be affected. If you are prone to constipation, dehydration can make stools harder and more difficult to pass. The bowel draws water back into the body when fluid intake is low, which can leave stools drier and slower moving.

Hydration also matters if you are prone to diarrhoea. Loose stools do not just mean water loss. They can also mean loss of electrolytes, particularly sodium and potassium. This is one reason why oral rehydration salts are often recommended when diarrhoea is more than mild, especially when travelling, in hot weather, or if you are at higher risk of dehydration.

This is where the “just drink more water” advice can be too simplistic. Water matters, but if you are losing fluid through sweat or diarrhoea, you may also need to think about the minerals being lost alongside it.

Signs You May Need More Electrolytes

Electrolytes are minerals that carry an electrical charge when dissolved in fluid. They help your body maintain fluid balance and support normal nerve and muscle function.

The main electrolytes people tend to hear about are sodium and potassium, but magnesium, calcium, chloride, phosphate and bicarbonate are also part of the picture. You get these through food and fluids, and your kidneys play a major role in keeping levels balanced.

You may need to pay more attention to electrolytes if you are sweating heavily, exercising for longer periods, spending time in hot weather, travelling in a hot climate, drinking more alcohol than usual, or losing fluid through vomiting or diarrhoea.

That does not automatically mean you need a sports drink. It means your hydration strategy may need to be more than a few sips of water.

Sweating, Fatigue and Dizziness

Sweat contains water and electrolytes, especially sodium. Some people lose more salt through sweat than others. You may notice this if your clothes have white marks after exercise, your skin tastes salty, or you feel unusually wiped out after sweating heavily.

The NHS advises that heat exhaustion can happen during hot weather or exercise. Symptoms may include tiredness, dizziness, headache, feeling sick, excessive sweating, cramps and intense thirst. If someone does not improve after cooling down, or symptoms become more serious, medical help is needed.

This is particularly important for older adults, children, pregnant women, people with heart or kidney conditions, those taking certain medications, and anyone who is unwell. In these situations, dehydration and heat illness can become more serious more quickly.

For most healthy adults, prevention is practical rather than complicated. Drink regularly across the day, keep an eye on urine colour, increase fluids in hot weather or after sweating, and include mineral-rich foods rather than relying on coffee, alcohol or occasional large glasses of water.

Food-First Hydration Strategies

For most people, hydration support should start with food and routine, rather than supplements.

The NHS recommends aiming for around 6 to 8 cups or glasses of fluid per day, although you may need more if you are in a hot environment, physically active, pregnant or breastfeeding. Water is the obvious choice, but it is not the only one. Herbal teas, milk, smoothies, soups and water-rich foods can all contribute to fluid intake. Tea and coffee can contribute too, although relying heavily on caffeine may not be ideal if you are anxious, sleep deprived or prone to reflux or loose stools.

Water-rich foods can be particularly helpful in summer. Cucumber, tomatoes, courgettes, lettuce, watermelon, strawberries, citrus fruits, peppers, soups, yoghurt and smoothies all provide fluid as well as nutrients.

Electrolyte-rich foods can also be built into normal meals:

• Potassium is found in foods such as:
  • potatoes, bananas, avocado, spinach, beans, lentils, yoghurt, fish and dried fruit. 
• Magnesium is found in:
  • nuts, seeds, wholegrains, dark chocolate, leafy greens and legumes. 
• Calcium comes from:
  • dairy foods, calcium-set tofu, fortified plant milks, tinned fish with bones and some leafy greens. 
• Sodium is usually easy to obtain from the diet, but if you are sweating heavily or losing fluid, you may need a little salt with meals rather than eating very low salt all the time.

A practical summer hydration day might look like this:

Have water on waking, then breakfast with fluid and minerals, such as Greek yoghurt with berries and seeds, or eggs with sourdough and spinach.

Keep a bottle with you during the day, especially if travelling, commuting or spending time outdoors.

Include a water-rich lunch, such as a chicken and avocado salad with potatoes, a lentil and vegetable soup, or a salmon rice bowl with cucumber and peppers.

Add mineral-rich snacks where needed, such as fruit with yoghurt, oatcakes with hummus, a handful of nuts and seeds, or watermelon with feta.

This is simple, but it can make a real difference. Many people do not need a complicated hydration plan. They need regular fluids, enough minerals, enough food and a better awareness of when their needs increase.

When Electrolyte Drinks May Be Useful

Electrolyte drinks can be useful, but they are not all created equal and they are not automatically needed every day.

For general hydration, most people can meet their fluid and mineral needs through regular drinks, balanced meals and electrolyte-rich foods. But there are situations where electrolytes may be genuinely helpful, particularly when fluid losses are higher.

This includes endurance exercise, such as long runs, cycling, hiking, triathlon training or events lasting longer than around 60 minutes. It can also include exercising in hot or humid weather, heavy sweating, long travel days in hot climates, diarrhoea or vomiting, working outdoors, or feeling light-headed, headachy or unusually wiped out after sweating.

During endurance exercise, you are not just losing water. Sweat contains electrolytes, particularly sodium, and the longer you exercise, the more relevant this becomes. This is why plain water may not always be enough for longer or hotter sessions. If you are sweating heavily and drinking lots of plain water, but not replacing electrolytes, you may still feel flat, headachy or depleted.

I generally recommend a mineral-only electrolyte rather than a sugary sports drink for most clients. Many sports drinks and electrolyte powders contain added sugars, dextrose, glucose syrups, artificial sweeteners, flavourings, colourings or other additives that may not suit a sensitive gut. For some people, especially those with IBS, bloating, reflux, diarrhoea tendency, PCOS or blood sugar instability, these ingredients can be unhelpful.

This does not mean carbohydrate is not relevant for endurance exercise. It can be. But in practice, I often prefer clients to get their fuelling from real food wherever possible and use electrolytes separately for mineral replacement. This allows you to tailor hydration and fuelling more carefully, rather than relying on a brightly coloured sports drink that may not be right for your gut or your blood sugar.

For example, someone doing a long walk, run, cycle or hike might use a mineral-only electrolyte in water, then fuel with tolerated foods such as a oatcakes or rice cakes with nut butter, potatoes with salt, a simple homemade flapjack, sourdough with nut butter, or another carbohydrate-rich food that suits their digestion. For people with IBS, this can be much easier to personalise than using a standard sports drink.

For a short gym session, gentle walk, Pilates class or easy 30-minute jog, you probably do not need a special electrolyte drink. Water and normal meals are usually enough. But for longer runs, long bike rides, hot-weather training, races, long hikes or heavy sweat sessions, a more structured hydration plan may be useful.

How to Choose a Good-Quality Electrolyte Supplement

If you do decide to use an electrolyte product, it is worth reading the label carefully rather than assuming all products are created equal.

Some electrolyte supplements are good quality and can be genuinely useful in the right context. Others are little more than sugary flavoured drinks, or contain sweeteners, colours and additives that may aggravate bloating, reflux or loose stools.

A good-quality electrolyte product is usually one that has:

• A simple ingredient list
  Ideally, you want minerals without lots of flavourings, colourings, sweeteners, preservatives or “wellness” extras. The more sensitive your gut, the more important this becomes.
• Meaningful mineral content
  Sodium is often the most relevant electrolyte for sweat losses, but potassium, magnesium and chloride may also be included. Be aware that some products are marketed as electrolytes but contain very small amounts of minerals.
• No unnecessary sugar or dextrose
  Dextrose and glucose can be useful in specific oral rehydration products for diarrhoea, where the glucose-sodium ratio helps absorption. But for everyday hydration or mineral replacement during summer activity, many people do not need added sugar in their electrolyte drink. If you need carbohydrate for endurance exercise, it may be better to add this from food that suits you.
• No gut-irritating sweeteners or sugar alcohols
  Some products contain sorbitol, xylitol, mannitol or other polyols, which can aggravate bloating or diarrhoea in people with IBS. Some also contain high-dose vitamin C, caffeine, strong acids or flavourings that may not suit reflux-prone clients.
• A format that works for real life
  Drops, sachets or powders can all work. Liquids such as mineral electrolyte drops can be useful because they are easy to add to water and do not necessarily contain flavourings or sweeteners. The best product is the one you tolerate and will actually use.

It is also important to be wary of exaggerated “wellness” claims. You do not need an electrolyte drink to detox, cleanse, alkalise or magically fix fatigue. Electrolytes support normal fluid balance, nerve signalling and muscle function. That is useful and important, but it should not be overpromised.

Electrolyte products are not appropriate for everyone to use regularly without advice. If you have kidney disease, heart failure, high blood pressure requiring salt restriction, are on fluid restriction, or take medications that affect fluid or potassium balance, such as some diuretics, ACE inhibitors or ARBs, check with your GP or pharmacist before using electrolyte supplements regularly.

How to Protect Your Gut While Travelling

If you have a sensitive gut, travelling can feel like a gamble. You might feel fairly fine at home, then suddenly find that a flight, a hotel breakfast buffet, a few late nights, or a change in water is enough to trigger bloating, constipation, loose stools, reflux or that familiar “my digestion has gone off the rails again” feeling.

This is especially common if you experience IBS-type symptoms, have a history of SIBO, react to certain foods, or know that stress affects your digestion. The real frustration is that holidays are supposed to be relaxing, but for many people, the lack of routine can make their guts feel unpredictable.

The aim is not to eat perfectly while you are away. I don’t think holidays should revolve around rigid food rules! Instead, let’s see what it takes to build a little digestive resilience before you travel, work on understanding your likely triggers, and have a calm plan for what to do if symptoms flare – so that your gut doesn’t spoil your holiday.

Why Travel Can Trigger Gut Symptoms

Your gut *loves* routine more than we often realise. At home, your digestive system has its cues. You may generally wake up at a similar time, drink your usual morning drink, eat familiar meals with familiar foods, move around during the day, and then go to bed at a predictable time. When you travel, many of those cues disappear.

Long journeys can slow bowel motility because you are sitting for hours, moving less, and often delaying going to the loo. Flights can also add to dehydration as cabin air is dry and many of us drink less to avoid needing a wee. Add in airport food, more caffeine, alcohol, later meals and a different sleep pattern, and your gut has to adapt fairly swiftly.

For someone with IBS, this can be enough to get symptoms going. IBS is not simply a “food problem”. It involves the gut-brain axis, gut motility, visceral sensitivity, the microbiome, immune signalling and stress response. This is why your symptoms may flare on holiday even if you have not eaten anything obviously “wrong”.

It also explains why a purely restrictive approach often doesn’t work. If you only focus on avoiding foods, but ignore hydration, stress, sleep, meal timing and bowel routine, you may miss some of the bigger drivers.

Hydration, Routine and Digestive Resilience

Hydration sounds basic, but it is one of the most useful foundations for travel digestion.

When you are dehydrated, stools can become harder and more difficult to pass. If you are prone to diarrhoea, dehydration can also make you feel weak, headachy and wiped out more quickly. Hot weather, sweating, alcohol, salty meals, vomiting and loose stools all increase your need for fluids.

For most people, the simplest approach is to start hydrating before the journey, not once you already feel unwell. Have a drink before you leave home, take an empty bottle through airport security and refill it before boarding, and keep sipping during the journey. If you are somewhere hot, walking a lot, sweating heavily or have loose stools, oral rehydration salts can be useful because they replace electrolytes as well as fluid.

I would also think about your “gut anchors”. These are the small routines that tell your digestive system that not everything has changed. This might be having breakfast within a reasonable window, taking a short walk in the morning, drinking water before coffee, or keeping one familiar meal each day.

It does not need to be complicated. For some people, a familiar breakfast makes all the difference. Something like Greek yoghurt with berries and seeds, porridge with ground flaxseed, eggs with sourdough, or a simple protein-rich smoothie can give the gut a more predictable start to the day.

Food Hygiene and Gut Health

When we talk about gut symptoms on holiday, there are two separate issues to think about.

The first is your own gut sensitivity: IBS, bloating, constipation, reflux or food reactions. The second is exposure to unfamiliar bacteria, viruses or parasites through food and water.

Travellers’ diarrhoea is most often linked to contaminated food or water. The risk varies depending on where you are travelling, the local sanitation infrastructure and how food is prepared. It is not always possible to avoid every risk, and even careful travellers can become unwell, but sensible food hygiene still matters.

If you are travelling somewhere where water safety is uncertain, be cautious with tap water, ice, salads washed in local water and food that has been sitting around for a long time. Food that is cooked thoroughly and served hot is usually a safer option than lukewarm buffet food. Fruit you can peel yourself may be a better choice than pre-cut fruit. Handwashing before eating is still one of the simplest and most overlooked forms of gut support.

That does not mean becoming frightened of food! It simply means being more discerning in situations where your gut is more exposed.

If you do develop diarrhoea, the priority is fluid and electrolyte replacement. Seek medical help if you have blood in the stool, a high fever, severe pain, signs of dehydration, persistent vomiting, or symptoms that do not settle.

Managing IBS and Bloating Abroad

If bloating is your main issue, it is worth thinking about the “stacking effect”. Many people can tolerate one trigger, but not five at once. For example, you may be fine with a glass of wine at home, but not when it comes after a long flight, a salty airport meal, poor sleep, fizzy drinks, a rich restaurant dinner and very little water.

This is where a more flexible approach can be helpful. Rather than trying to avoid everything, you can choose which digestive load matters most to you. If you know onions and garlic trigger bloating, you might keep those lower while still enjoying a pudding. If alcohol affects your gut, you might alternate with water or keep it to earlier in the evening. If raw salads make you balloon, cooked vegetables, rice, potatoes, fish, chicken or eggs may be easier options.

Meal timing can also matter. Skipping breakfast, grazing all day and then eating a very large late dinner can be difficult for IBS. The migrating motor complex, often described as the gut’s cleansing wave, works best when there are gaps between meals. Constant snacking can make some people feel more bloated, especially if they are prone to SIBO-type symptoms.

Constipation needs a slightly different strategy. Travel constipation is often driven by reduced movement, dehydration, ignoring the urge to go, and a lack of familiar fibre. Soluble fibre is usually the gentler place to start. Oats, ground flaxseed, chia, peeled potatoes, carrots, berries and stewed fruit are often better tolerated than suddenly loading up on bran, raw salads or large portions of beans.

For diarrhoea-prone IBS, the focus may be on calming the gut rather than pushing fibre higher. This may mean reducing very high-fat meals, limiting caffeine, avoiding sugar-free sweets or chewing gum containing polyols, and being cautious with large amounts of fruit juice, alcohol or spicy food.

This is why generic IBS advice can fall short. The right travel strategy depends on your pattern.

Simple Nutrition Strategies Before and During Travel

The best time to support your gut is before you travel, not once symptoms have already taken over. In the week before you go away, try to keep food steady and familiar. This is not the moment to start a new gut protocol, suddenly double your fibre intake, or trial several new supplements. A sensitive gut usually responds better to consistency.

A helpful pre-travel plate might include protein, cooked veggies, a carb you tolerate well and some healthy fats. For example, salmon with potatoes and greens, chicken with rice and roasted vegetables, eggs with sourdough and spinach, or a simple lentil soup if you tolerate legumes. This kind of meal supports blood sugar balance, bowel regularity and energy without overloading the digestive system.

Food-wise, aim for familiarity with flexibility. If breakfast buffets overwhelm you, look for protein first. Eggs, yoghurt, smoked salmon, cheese, nuts or seeds can help steady energy and appetite. Then add a carb you tolerate, such as oats, potatoes, sourdough or fruit. At lunch and dinner, the simplest gut-friendly structure is usually protein, cooked plants, a starchy carbohydrate and olive oil or another fat you tolerate well.

This also helps reduce the classic holiday pattern of coffee and pastries for breakfast, snacks through the day, then a very large evening meal. There is nothing wrong with enjoying local foods, but your gut may cope better if you give it some structure around the edges.

Your Travel Gut Support Kit

It can be helpful to pack a small gut support kit, especially if you know your digestion is easily thrown off when you travel. This doesn’t need to be complicated, and it does not mean taking lots of supplements “just in case”. The aim is to have a few sensible, familiar tools with you so that you are not trying to solve gut symptoms in a pharmacy abroad when you are tired, bloated or unwell.

A useful travel gut support kit might include:

• Oral rehydration salts
  These can be very useful if you develop diarrhoea, are sweating more than usual, or are travelling somewhere hot. Water alone doesn’t replace the electrolytes lost through loose stools, vomiting or heavy sweating. Oral rehydration salts help replace both fluid and key minerals such as sodium and potassium. They are particularly important if diarrhoea is persistent, although you should seek medical advice if symptoms are severe, bloody, associated with fever, or if you feel dehydrated or very unwell.
• Your usual medications and any prescribed digestive support
  Pack these in your hand luggage rather than your checked suitcase. This is especially important if you take regular medication, use prescribed reflux medication, have antispasmodics, have been advised to use loperamide in certain situations, or need medication for another health condition. Keep them in their original packaging where possible, and check travel rules if you are taking medicines across borders.
• A few familiar snacks you already tolerate well
  Travel often means long gaps between meals, limited food choices and lots of beige convenience food. Packing familiar snacks can help you avoid getting over-hungry, which may lead to eating quickly or choosing foods that are more likely to trigger symptoms. Good options might include oatcakes, plain nuts or seeds, a simple protein bar, rice cakes, nut butter sachets, plain crackers, or fruit you know suits you. The key is familiarity. Do not pack something “healthy” that you rarely eat if you do not know how your gut responds to it.
• A soluble fibre option, if this is already part of your routine
  Soluble fibre can help some people with bowel regularity and stool consistency, but it should be introduced carefully. If you already tolerate ground flaxseed, chia seeds, oats, PHGG or another soluble fibre, it may be worth taking a small amount with you. However, travel is not the best time to start a new fibre powder or suddenly increase your fibre intake, as this can worsen bloating or gas in sensitive people.
• Saccharomyces boulardii, if it is suitable for you and you have trialled it before travelling
  Saccharomyces boulardii is a probiotic yeast rather than a bacterial probiotic. It has been studied in relation to diarrhoea, including antibiotic-associated diarrhoea and travellers’ diarrhoea. Research suggests that specific strains, particularly Saccharomyces boulardii CNCM I-745, may help reduce the risk of travellers’ diarrhoea in adults. 

However, it should not be introduced for the first time on the day of travel, and it should not replace food hygiene, safe water choices or oral rehydration salts if diarrhoea occurs. It is also not suitable for everyone. Anyone who is immunocompromised, seriously unwell, has a central venous catheter, is pregnant, is taking complex medication, or has been advised to avoid probiotics should speak to their GP, pharmacist or medical team before using it.

• Herbal teas or simple digestive drinks you know you tolerate
  Peppermint tea, ginger tea or chamomile tea may be soothing for some people, although peppermint can aggravate reflux in others. Taking a few tea bags can be a simple way to create a calming evening routine, especially if your gut is affected by stress, poor sleep or late meals.

I would also avoid introducing lots of new products just before travelling. A common mistake is to panic-buy probiotics, enzymes, fibre powders, magnesium or herbal supplements the week before a holiday. Even useful products can cause bloating, looser stools or discomfort if they are not right for you or if the dose is too high. The safest travel strategy is usually to stick with what your body already knows.

What To Do If Symptoms Flare

Even with the best planning, digestive symptoms can still happen. That does not mean you have failed. It means your gut has met a lot of change at once. If you feel bloated, constipated or sluggish, come back to the basics. Choose simple meals, drink regularly, walk gently, avoid grazing all day, and allow yourself time to use the bathroom rather than rushing straight into the next activity.

If you develop loose stools, the priority is hydration. Use oral rehydration salts if needed, keep food simple for 24 hours, avoid alcohol temporarily and seek medical help if symptoms are severe, persistent, bloody, associated with fever, or you feel very unwell.

And if bloating, urgency, constipation or diarrhoea regularly affect your holidays, work trips or social life, it may be worth looking more deeply at what is driving your symptoms. Gut issues can be influenced by food, stress, motility, the microbiome, infections, medications, hormones and underlying medical conditions. You do not have to keep guessing.
