The Food Mood Connection
How Nutrition Shapes Mental Wellbeing
Key Takeaways
If you have ever noticed feeling irritable when you skip meals, or more focused after eating well, you’ve already experienced the food–mood connection in action.
Mental wellbeing is truly complex and influenced by a lot of different factors, including sleep, stress, movement, and just what’s going on in life. However, nutrition is one area that we often overlook, despite its playing a fundamental role in how our brains function.
For many people I work with, symptoms such as anxiety, low mood, brain fog, and feeling overwhelmed by food choices are common. The good news is that small, consistent changes to how you eat can support your mental wellbeing in a realistic and sustainable way.
How Food Influences Brain Chemistry
The brain is an energy-demanding organ, using around 20 percent of the body’s total energy intake. It relies on a steady supply of nutrients to produce neurotransmitters (brain signalling chemicals), regulate inflammation, and maintain healthy nerve signalling.
Neurotransmitters such as serotonin, dopamine, and GABA play key roles in mood, motivation, and stress response. These are made from nutrients found in food, particularly amino acids, vitamins, and minerals.
For example:
Research continues to highlight the relationship between dietary patterns and mental health outcomes. Diets rich in whole foods such as vegetables, fruits, whole grains, healthy fats, and quality protein sources are associated with a lower risk of depression and improved psychological wellbeing.
Nutrients Linked to Mood and Resilience
Rather than focusing on single “superfoods,” it is much more helpful to consider overall dietary patterns and checking we’re getting sufficient nutrients overall.
A number of nutrients have been consistently linked to mental wellbeing:
Blood Sugar, Fats and Micronutrients
Blood sugar balance is one of the most important, yet often overlooked, factors in mental wellbeing.
Frequent spikes and crashes in blood glucose can contribute to:
This is something I explore further in my November blog on steady energy.
Including a balance of protein, healthy fats, and fibre at meals can help stabilise blood sugar levels, supporting more consistent energy and mood throughout the day.
Healthy fats, particularly from sources such as olive oil, nuts, seeds, and oily fish, also play a structural role in brain health. Meanwhile, micronutrients from a wide variety of plant foods support resilience to stress and cognitive function.
Gentle Nutrition Strategies for Mental Wellbeing
When you are already feeling overwhelmed, complicated dietary rules can often make things worse. A gentle, supportive approach can be far more effective.
Here are some realistic starting points:
1. Prioritise regular meals
Aim to eat 3 good meals a day in a 12-hour window to support stable blood sugar and energy levels.
2. Build balanced plates
Include a source of protein, healthy fats, and fibre-rich carbohydrates at every single meal – not just dinner.
3. Add, rather than restrict
Focus on including more nutrient-dense foods, rather than removing foods entirely.
4. Support gut health
There is a strong connection between the gut and brain, often referred to as the gut–brain axis. You can read more in my March blog on gut health. Including fibre-rich foods and fermented foods may support this relationship.
5. Keep it simple
Consistency matters more than perfection. Simple meals that you can repeat are often the most supportive.
Improving your nutrition will not replace professional mental health support where needed, but it can be a valuable part of a wider approach to wellbeing.
As a BANT-registered Nutritional Therapist, I do not diagnose or treat medical conditions, and I always recommend speaking with your GP if you are experiencing ongoing mental health symptoms.

Move for Stronger Bones
When people think about protecting their bones as they age, nutrition is often the first thing that comes to mind. Calcium, vitamin D and other nutrients certainly play an important role in maintaining bone health. However, diet is only part of the picture.
Physical activity is another key factor that supports strong bones throughout life. In fact, bones respond to movement in much the same way that muscles do. When we use them regularly, they adapt and become stronger. When they are used less, they can gradually weaken.
This is why regular movement, particularly weight-bearing exercise and strength training, is considered an important part of osteoporosis prevention and healthy ageing. The encouraging news is that supporting bone health does not necessarily require intense workouts. Consistent, varied movement can help maintain bone strength and reduce the risk of fractures later in life.
How Bones Respond to Physical Activity
Bones are living tissue that continually remodels itself. Throughout life, bone tissue is constantly being broken down and rebuilt in a process known as bone remodelling.
Mechanical stress plays an important role in this process. When bones experience the gentle stress created by movement and muscle contraction, specialised bone cells are stimulated to strengthen the bone structure.
This process is sometimes referred to as mechanical loading. Activities that place controlled stress on the skeleton encourage the body to maintain bone density. In contrast, long periods of inactivity can lead to reduced bone stimulation. Research shows that sedentary lifestyles may contribute to gradual bone loss over time.
Regular physical activity also helps maintain muscle strength, coordination and balance. These factors are particularly important for reducing the risk of falls, which are a major cause of fractures in older adults.
For these reasons, many public health guidelines recommend combining good nutrition with regular exercise to support bone health throughout life.
The Best Types of Exercise for Bone Strength
Not all forms of exercise affect bones in the same way. Activities that place gentle stress on the skeleton are particularly helpful for maintaining bone density.
Two types of exercise are especially beneficial: weight-bearing exercise and strength training.
Weight-Bearing and Strength Training
Weight-bearing exercises are activities where the body works against gravity while standing. These movements encourage the bones in the legs, hips and spine to adapt and strengthen.
Examples include:
Even simple activities such as brisk walking can provide beneficial stimulation for bone tissue.
Strength or resistance training is another important form of exercise. When muscles contract during resistance exercises, they pull on the bones they are attached to. This mechanical force stimulates bone cells and encourages bone maintenance.
Examples of strength training include:
Strength training also helps maintain muscle mass, which becomes increasingly important with age. Stronger muscles support joint stability and may reduce the risk of falls.
For many people, combining weight-bearing movement with resistance exercises provides a well-rounded approach to supporting bone health.
Building Bone-Supportive Movement Into Daily Life
The idea of exercise can sometimes feel overwhelming, particularly if someone has been inactive for a while. However, supporting bone health does not necessarily require long gym sessions or high-intensity workouts.
Small, consistent habits can make a meaningful difference over time.
For example, walking regularly, taking the stairs where possible, gardening or joining a local exercise class can all contribute to maintaining bone strength.
Balance and coordination exercises can also be beneficial, particularly as we get older. Activities such as yoga or tai chi may help improve stability and reduce the risk of falls.
The key is consistency. Building movement into everyday life is often more sustainable than relying on occasional bursts of activity.
It is also important to choose activities that are enjoyable. When exercise feels rewarding rather than like a chore, it is far easier to maintain in the long term.
Nutrition and Movement Work Together
Exercise and nutrition work together to support bone health. Physical activity stimulates bone remodelling, while nutrients provide the building blocks needed for bone structure.
Ensuring adequate intake of calcium, vitamin D, protein and other key nutrients can help support the body’s natural bone maintenance processes.
If you would like to learn more about the role of diet in supporting bone strength, you can read my blog on osteoporosis prevention nutrition.
You may also enjoy my calcium-rich kale and new potato frittata recipe, which provides several nutrients that contribute to normal bone maintenance.
Supporting Healthy Ageing
Strong bones support independence, mobility and overall quality of life as we age. While genetics and hormones play a role in bone health, lifestyle factors such as diet and physical activity remain important.
Regular movement, combined with balanced nutrition, provides a practical and accessible way to support bone health across the lifespan. Whether it is walking more, building strength or simply staying active in everyday life, these habits can contribute to maintaining bone strength for the years ahead.

Kale and New Potato Frittata
When people think about supporting bone health, nutrients such as calcium and vitamin D are often the focus. However, bones rely on a combination of nutrients working together, including protein, magnesium and vitamin K.
Meals that combine these nutrients can help support overall bone health as part of a balanced diet. This kale and new potato frittata is a perfect example. It provides protein from eggs, calcium from cheese and milk, and beneficial plant nutrients from leafy greens.
Frittatas are also super practical for busy days - they can be prepared in advance, enjoyed warm or cold, and work well for lunch, dinner or even breakfast.
How This Recipe Supports Bone Health
Several nutrients in this recipe contribute to the maintenance of normal bones.
Kale is a nutrient-dense leafy green that contains vitamin K. This nutrient plays a role in bone metabolism and supports the proteins involved in maintaining bone structure. Kale also provides small amounts of calcium and magnesium.
Eggs contribute high-quality protein, which forms part of the structural matrix of bone tissue. Adequate protein intake also supports muscle health, which is important for balance and stability as we age.
Cheese and milk provide calcium, a mineral that contributes to the maintenance of normal bones. Including calcium-rich foods regularly can help support overall intake as part of a varied diet.
New potatoes provide fibre and potassium while helping to make the meal satisfying and balanced.

The Surprising Link Between Microbes and Minerals
When we think about bone health, nutrients such as calcium and vitamin D usually come to mind. These are certainly important, but research over the past decade has highlighted another interesting factor that may influence bone health: the gut microbiome.
The trillions of microbes that live in our digestive tracts play multiple roles in our health. They help digest certain foods, support the immune system, and influence inflammation in the body. Scientists are now exploring how these microbes may also affect bone metabolism, mineral absorption, and long-term bone strength.
This relationship is sometimes referred to as the gut–bone axis. While research in this area is still evolving, early findings suggest that gut health may play a role in supporting healthy bones. Understanding this connection offers another perspective on how best we can help keep our bones strong.
How the Gut Influences Bone Metabolism
Bone tissue is constantly being remodelled through a balance between bone formation and bone breakdown. This process is influenced by hormones, nutrients, physical activity and inflammation.
The gut microbiome may affect this balance in several ways.
One pathway involves its influence on the immune system. A large proportion of the immune system is actually located in the gut, and gut microbes have some influence on immune signalling throughout the body. Chronic low-grade inflammation is known to affect bone turnover, and researchers believe the microbiome may help regulate this process.
Gut bacteria also produce beneficial compounds known as short-chain fatty acids, which are created when certain microbes ferment dietary fibre. These compounds have been linked to a range of health benefits, including effects on immune regulation and mineral metabolism. Some studies suggest they may support bone formation and reduce bone resorption.
Another potential pathway involves hormones and signalling molecules that influence bone cells. Early research indicates that the microbiome may interact with these pathways, although scientists are still exploring the mechanisms involved.
While this field is still developing, these findings highlight how closely connected different systems of the body can be.
Mineral Absorption and the Microbiome
The gut plays a central role in nutrient absorption. For bones to remain strong, minerals such as calcium, magnesium and phosphorus must be absorbed effectively from food. A healthy digestive system helps ensure that these nutrients are actually available to the body. Factors that affect gut health may therefore influence mineral absorption.
The microbiome can contribute to this process in several ways. Some beneficial bacteria can help create an environment in the gut that improves mineral solubility, making it easier for the body to absorb nutrients such as calcium. Short-chain fatty acids produced during fibre fermentation may also help increase calcium absorption in the large intestine. Diets rich in plant foods and fibre may therefore support both gut health and mineral metabolism.
In addition, certain gut bacteria appear to influence vitamin production and metabolic pathways that affect bone health. Although this research is still emerging, it provides another reason to consider digestive health as part of a broader approach to supporting bones.
What the Evidence Currently Shows
Much of the research on the gut–bone axis is still developing, but several studies have begun to explore this connection.
Animal studies have shown that changes in gut microbiota can influence bone density and bone remodelling. Human studies are more limited, but emerging research suggests that microbial diversity and dietary patterns may be linked with bone health outcomes.
For example, diets rich in fibre, vegetables and plant foods tend to support a diverse microbiome. These same dietary patterns are also associated with improved mineral intake and overall musculoskeletal health.
There is also growing interest in the potential role of probiotics and prebiotic fibres in supporting bone metabolism, although more research is needed before firm conclusions can be drawn.
Supporting Both Gut and Bone Health Through Diet
From a practical perspective, supporting gut health and bone health often involves many of the same dietary habits.
A varied diet that includes fibre-rich plant foods, adequate protein and key minerals provides nutrients that support both the microbiome and bone metabolism.
Helpful dietary habits may include:
These dietary patterns support overall wellbeing while also helping to create an environment that may benefit both the microbiome and the skeleton.
If you would like to learn more about nutrition strategies that support bone health, you can also read my blog on osteoporosis prevention nutrition. You may also find my guide to supporting gut health through diet and lifestyle helpful.
A Whole-Body Approach to Bone Health
The idea of a gut–bone axis highlights an important point. The body’s systems rarely work in isolation. Digestive health, immune balance, nutrient intake and lifestyle habits all interact to influence long-term health. Supporting the gut microbiome through balanced nutrition may therefore play a role in maintaining bone strength over time.
While research in this area continues to develop, focusing on whole foods, dietary diversity and overall digestive health is a sensible starting point for many people. If you have any questions about this, don’t hesitate to get in touch.
Eating for Stronger Bones
Many people start thinking about bone health when they reach midlife. Maybe a parent has been diagnosed with osteoporosis, or maybe joint stiffness and aches are becoming a bit more noticeable. This can often lead to questions about diet, calcium intake and whether supplements might be necessary – but it can be confusing.
What many of us don’t realise is that bone health is influenced by the choices we make over many years. Bones are living tissue that constantly renew themselves, so therefore the nutrients we eat, the way we move our bodies, and our overall lifestyle all influence how strong our bones remain as we age.
While bone density naturally changes over time, research shows that diet and lifestyle can really help support bone strength and reduce the risk of fractures. Supporting bone health is therefore not just something to think about later in life. It is something that can be supported at every age.
How Bone Health Changes Over Time
Our bones are continually being broken down and rebuilt through a process called bone remodelling. During childhood and adolescence this process works in our favour, as bone formation happens faster than bone breakdown. This allows us to build strong bones and reach peak bone mass, usually by our late twenties.
After this point, the balance gradually begins to shift. Bone breakdown slowly starts to exceed bone formation, meaning bone density gradually declines with age.
For women, this change can become more pronounced after menopause. Oestrogen helps maintain bone density, and when levels fall during menopause the rate of bone loss can increase. This is one reason why women are more likely to develop osteoporosis later in life.
However, bone health is not determined by hormones alone - nutrition, physical activity and lifestyle habits all influence it. Studies consistently show that dietary patterns rich in essential nutrients can support bone strength and help reduce the risk of fractures as we age.
Nutrients That Support Bone Strength
When people think about nutrition for osteoporosis prevention, calcium is usually the first nutrient that springs to mind. Calcium is indeed a key component of bone structure, but healthy bones rely on a range of nutrients working together.
Rather than focusing on a single nutrient, it is more helpful to think about overall dietary patterns that support bone health.
Calcium, Vitamin D, Protein and More
Calcium contributes to the maintenance of normal bones and is an important part of osteoporosis prevention nutrition. Adults in the UK generally need around 700 mg of calcium per day.
Calcium can be found in a variety of foods including:
Vitamin D is another essential nutrient because it helps the body absorb calcium effectively. In the UK, sunlight is the main source during spring and summer months. During autumn and winter, dietary sources such as oily fish and eggs become more important, and public health guidance recommends vitamin D supplementation for many adults.
Protein also plays a huge role in maintaining bone structure, as bones contain a protein framework that gives them flexibility and strength. Adequate protein intake supports both bone and muscle health, which is important for maintaining balance and reducing the risk of falls. Research shows that improving both protein and calcium intake in older adults can help reduce the risk of falls and fractures, particularly where dietary intake has previously been low.
Other nutrients that support bone health include magnesium, vitamin K and zinc. These nutrients are found in whole foods such as nuts, seeds, legumes, vegetables and whole grains. Increasing vegetable intake may also benefit musculoskeletal health. Green leafy vegetables are a great source of vitamin K and other plant compounds that may support both bone metabolism and muscle function.
A varied, balanced diet is one of the most effective strategies for supporting bone health.
Common Bone Health Myths
There are several common misconceptions about osteoporosis prevention nutrition.
One myth is that dairy products are the only way to obtain enough calcium. While dairy foods are a convenient source, as we saw above, calcium can also be obtained from plant foods, fortified products, nuts and seeds.
Another misconception is that bone health only becomes important later in life. In reality, the foundations for strong bones are actually laid early in life and maintained through adulthood.
Finally, it is a myth that supplements alone can prevent osteoporosis. While supplements may be useful in some situations, they are not a substitute for a balanced diet and healthy lifestyle.
Nutrition also works alongside other important factors including regular weight-bearing exercise, strength training, maintaining a healthy body weight and avoiding smoking.
A Whole Diet Approach to Osteoporosis Prevention Nutrition
When thinking about osteoporosis prevention nutrition, it can be helpful to focus on dietary patterns rather than individual nutrients. Eating a wide range of whole foods provides the combination of vitamins, minerals and protein needed to support bone metabolism.
Simple habits that support bone health include:
These are great habits to support overall health whilst also supporting our bone health.
Frequently Asked Questions About Bone Health Nutrition
Do I need dairy for strong bones?
Not necessarily. Dairy foods can be a convenient source of calcium, but calcium is also available in plant foods such as tofu, fortified plant milks, nuts and leafy greens.
Is it too late to support bone health after menopause?
No. While bone density naturally declines with age, nutrition, exercise and lifestyle changes can still help support bone strength and reduce fracture risk.
Should everyone take calcium supplements?
Not always. Many people can obtain sufficient calcium from food. Supplements may be appropriate in some cases, but this should be discussed with a qualified health professional.
Looking after your bones is a long-term investment in health. Supporting bone strength through balanced nutrition, regular movement and healthy lifestyle habits can help protect bone health throughout life.

Gut Testing: What’s Worth Doing - and What’s Not
If you’ve been struggling with bloating, irregular bowel habits, IBS-type symptoms or persistent digestive discomfort, it’s natural to start wondering:
Should I get a gut test?
A quick search online brings up everything from microbiome mapping and stool tests to SIBO breath testing, food sensitivity panels and parasite cleanses. It can be hard to know what’s evidence-based, what’s genuinely useful, and what might simply add more confusion (and expense).
In this blog, I’ll walk you through the most common gut tests people ask about, what they can and can’t tell us, and when it’s essential to involve your GP to rule out medical causes.
First: testing should match your symptoms
One of the biggest mistakes I see is people ordering tests before they’ve clarified what they’re trying to understand.
Gut symptoms can be driven by many factors, including:
A sensible testing strategy should always begin with:
For many people, we can make significant progress without extensive testing. But for others, testing can help us build a much more targeted plan.
Comprehensive stool and microbiome testing
One of the most commonly used functional tests is comprehensive stool testing, often referred to as microbiome testing.
A test like Genova GI Effects Stool Test or GI Map can provide insight into:
When this type of test may be useful
In practice, comprehensive stool testing may be worth considering if:
What it can’t do
Microbiome tests are not there to:
However, they can be useful when interpreted in context, particularly when results are combined with symptom patterns, diet quality, lifestyle factors and health history.
SIBO breath testing
SIBO (small intestinal bacterial overgrowth) is one of the most talked-about causes of bloating online. SIBO occurs when bacteria that normally live in the large intestine overgrow in the small intestine.
The most common test is a breath test, typically measuring hydrogen and methane (and sometimes hydrogen sulphide depending on the test available).
When SIBO testing might be appropriate
SIBO testing may be worth considering if there is:
A note on limitations
SIBO is complex. Breath testing has limitations and results need careful interpretation. Not all bloating is SIBO, and it’s common for people to go through multiple restrictive protocols unnecessarily when the driver is something else entirely (for example constipation, stress patterns, or weak digestion).
Asking your GP to test for coeliac disease
This is one of the most important points in the entire gut testing conversation:
If you have ongoing gut symptoms, especially diarrhoea, bloating, persistent fatigue, or nutrient deficiencies, it is sensible to rule out coeliac disease early. NICE guidelines recommend coeliac disease testing in people with persistent unexplained GI symptoms consistent with IBS, among other presentations.
If you suspect coeliac disease, it’s important that you continue eating gluten before testing. If gluten is removed before the blood test, results may become falsely normal.
This is one reason I don’t recommend removing gluten “just in case” without a clear plan, especially if symptoms are significant.
Your GP can arrange coeliac screening blood tests. If positive (or strongly suspected), further medical follow-up is needed.
FIT testing via your GP (especially if there is blood in stool)
If you notice blood in your stool, it’s important to speak to your GP promptly.
Other red flag symptoms include:
A FIT test (faecal immunochemical test) may be used in primary care to help assess the need for further investigation when symptoms suggest possible bowel disease.
This is not something to self-manage with supplements or elimination diets.
Food sensitivity testing: is it worth it?
Food sensitivity testing is often one of the first things people try when gut symptoms don’t improve. It’s understandable, because it feels like it might give a clear list of foods to avoid.
However, this is an area where it’s easy to spend money and end up more confused (and more restricted) than before.
Why food sensitivity tests often “light up”
With ongoing gut issues, especially if the gut lining is irritated or intestinal permeability is increased (sometimes referred to as “leaky gut”), food sensitivity tests can come back with long lists of positives.
This can happen because the immune system is more reactive when the gut barrier is not functioning optimally. In that situation, results can “light up like a Christmas tree” and leave you feeling like you can’t eat anything at all.
The downside
If we remove lots of foods based on a test result without addressing the underlying gut issue, it can lead to:
In clinic, it’s usually better to:
