Blood Sugar and Anxiety: What You Need to Know
Key Takeaways
If you experience anxiety, shakiness, irritability, or sudden drops in energy, did you know that your blood sugar levels may be playing a role?
While anxiety has many causes and can be influenced by psychological, environmental, and physiological factors, blood glucose regulation – or blood sugar balance - is one area that is often overlooked. Yet it could potentially have a big impact on how calm, focused, and emotionally balanced you feel throughout the day.
For many clients, symptoms such as anxiety, low mood, brain fog, and intense cravings are closely linked to how and when they eat.
How Blood Sugar Fluctuations Affect Anxiety
Blood sugar, or blood glucose, refers to the level of glucose circulating in the bloodstream. Glucose is the body’s primary source of energy, particularly for the brain.
After eating, blood sugar rises, triggering the release of insulin to help move glucose into cells. However, when meals are high in refined carbohydrates or lacking in protein and fat, this can lead to a rapid spike followed by a sharp drop in blood glucose.
These fluctuations can activate the body’s stress response.
When blood sugar drops too low, the body releases stress hormones such as adrenaline and cortisol to bring levels back up, as your body is concerned there won’t be enough fuel for the brain. This process can trigger symptoms that feel very similar to anxiety, including:
Research has shown that maintaining more stable blood glucose levels is associated with improved mood and reduced feelings of anxiety.
If you would like a broader overview of how nutrition influences mental wellbeing, you can read my recent blog on the food–mood connection.
Common Signs of Blood Sugar Imbalance
Blood sugar imbalances are not always that obvious, and many people experience symptoms without immediately linking them to how they are eating.
Glucose is the brain’s primary fuel, so fluctuations in blood sugar can directly affect cognitive function, mood, and energy levels. When blood glucose rises and falls rapidly, this can lead to periods where the brain is temporarily under-fuelled, contributing to symptoms such as difficulty concentrating, low mood, and mental fatigue.
You may notice this as mid-morning or mid-afternoon energy dips, particularly if meals are high in refined carbohydrates or if there are long gaps between eating. Feeling irritable or “hangry” when meals are delayed is another common sign, as the body responds to falling glucose levels by activating the stress response.
Cravings, particularly for sugary or high-carbohydrate foods, can also be a physiological response rather than a lack of willpower. When blood sugar drops, the body seeks quick sources of glucose to restore balance, often driving a preference for foods that provide rapid energy.
For some individuals, these fluctuations may also present as feelings of jitteriness, restlessness, or mild anxiety between meals, reflecting the involvement of stress hormones such as adrenaline in blood sugar regulation.
Anxiety, Energy and Cravings
These symptoms are often closely interconnected and can form a reinforcing cycle over time.
For example, a meal that is mostly made up of refined carbohydrates and low in protein or fat may be digested and absorbed quickly, leading to a rapid increase in blood glucose. This is typically followed by a compensatory insulin response, which can result in a relatively sharp decline in blood sugar levels.
As blood glucose falls, the body activates counter-regulatory mechanisms to maintain energy supply to the brain. This includes the release of stress hormones such as cortisol and adrenaline, which stimulate glucose production. While this is a normal physiological response, it can also produce sensations that mirror anxiety, including a racing heart, nervousness, and increased alertness.
At the same time, the brain signals a need for quick energy, often leading to cravings for sugary or highly processed foods. If this pattern repeats regularly, it can contribute to ongoing fluctuations in energy and mood, as well as a reduced ability to tolerate stress.
Over time, supporting more stable blood glucose levels through balanced meals and regular eating patterns may help reduce this cycle and promote more consistent energy and emotional regulation. This is something I explore in more detail in my November blog on insulin resistance.
Nutrition Strategies That Support Blood Sugar Balance
The goal is not to cut carbs completely or follow hideously restrictive rules, but to support more stable blood sugar levels through balanced, consistent eating patterns.
Here are some practical strategies:
1. Build balanced meals
Include protein, healthy fats, and fibre-rich carbs at each meal. This combination helps slow the release of glucose into the bloodstream.
2. Do not skip meals
Having 3 good meals per day within a 12 hour window, can help prevent large drops in blood sugar.
3. Choose whole food carbohydrates
Opt for foods such as oats, whole grains, vegetables, and legumes – rather than bread, pasta, pastries and sugary foods - where tolerated, which provide a slower release of energy.
4. Include protein at breakfast
Starting the day with a protein-rich meal may help support more stable energy and reduce cravings later on.
5. Be mindful of caffeine
Caffeine can amplify symptoms such as jitteriness and anxiety, particularly when consumed on an empty stomach.
6. Keep it realistic
Simple, repeatable meals are often the most sustainable. Perfection is not required to see benefits.
Supporting blood sugar balance can be a helpful part of managing anxiety, but it is not a replacement for appropriate medical or psychological care where needed.

Magnesium-Rich Dark Chocolate and Walnut Bites
Key Takeaways
If you are looking for a simple snack that supports both energy and relaxation, these dark chocolate and walnut bites are a great option.
They are comprised of ingredients naturally rich in magnesium, alongside healthy fats and fibre, making them a more balanced alternative to many processed snacks.
For those experiencing symptoms such as anxiety, low mood, or brain fog, small dietary additions like this can form part of a wider, supportive approach to nutrition.
Why Magnesium Supports Calm
Magnesium is an essential mineral involved in over 300 biochemical processes in the body, many of which are directly related to nervous system function.
It plays a role in regulating neurotransmitters, including those involved in the stress response, and is required for the proper functioning of the hypothalamic–pituitary–adrenal (HPA) axis. This system helps control how the body responds to stress.
Magnesium is also involved in the regulation of GABA, a neurotransmitter that promotes relaxation and helps to balance the excitatory effects of stress-related signals. Low magnesium status has been associated with increased susceptibility to stress, anxiety, and sleep disturbances.
In addition, magnesium contributes to blood glucose regulation and energy metabolism. This is particularly relevant, as fluctuations in blood sugar can influence mood and anxiety, as discussed in my blog on the food–mood connection.
While magnesium supplementation may be appropriate in some cases, increasing intake through whole foods is a practical and accessible starting point. Foods such as dark chocolate, nuts, seeds, and whole grains can all contribute to magnesium intake, alongside providing additional nutrients that support overall wellbeing.
These bites are quick to prepare and require minimal equipment, making them a useful option for batch preparation.
Ingredients (makes approximately 10–12 bites)
Method
These bites provide a combination of healthy fats, fibre, and a small amount of protein, which can help support more stable energy levels compared to high-sugar snacks.
Storage Tips
Store the bites in an airtight container in the fridge for up to one week.
They can also be frozen and defrosted as needed, which can be helpful if you prefer to prepare snacks in advance. Keeping a batch ready to go can reduce reliance on convenience foods and support more consistent choices during busy periods.
Recipes like this can be a simple way to incorporate nutrient-dense foods into your routine without adding complexity. While no single food will directly “treat” symptoms, these small additions can support overall dietary patterns linked to better mental wellbeing.

Top Tips: Snacks That Support Calm and Focus
Key Takeaways
Snacking is often seen as something to avoid, particularly when trying to improve health. However, when used appropriately, snacks can be a useful tool for supporting stable energy, concentration, and mood throughout the day.
For many people, long gaps between meals, busy schedules, or unbalanced meals can lead to dips in energy, increased anxiety, and difficulty focusing. In these situations, thoughtful snack choices can help to maintain more consistent blood glucose levels and support overall wellbeing.
The aim is not to snack constantly, but to use snacks strategically within a balanced eating pattern.
Why Snack Choice Matters for Mood
The types of foods you choose between meals can have a direct impact on both physiological and psychological responses.
Snacks that are high in refined carbohydrates or sugar, such as biscuits, pastries, or sugary drinks, are rapidly digested and absorbed. This can lead to a sharp rise in blood glucose, followed by a relatively quick decline. These fluctuations may contribute to symptoms such as fatigue, irritability, and difficulty concentrating.
As outlined in my blog on blood sugar and anxiety, drops in blood glucose can activate the release of stress hormones such as adrenaline and cortisol. While this is a normal regulatory mechanism, it can produce sensations that mirror anxiety, including restlessness, a racing heart, and increased alertness.
In contrast, snacks that include protein, healthy fats, and fibre are digested more slowly, leading to a more gradual release of glucose into the bloodstream. This supports more stable energy levels and may help to reduce the likelihood of mood fluctuations.
Protein plays a particularly important role, as it provides amino acids required for neurotransmitter synthesis. Nutrients such as tryptophan and tyrosine are involved in the production of serotonin and dopamine, which are key regulators of mood and motivation. Fibre and healthy fats further support satiety, glycaemic control, and, in the case of fibre, gut health, which is increasingly recognised as playing a role in the gut–brain axis.
Practical Snack Ideas for Real Life
When it comes to snacks, simplicity and structure are key. While snacks can be helpful, they are most effective when they sit within an overall pattern of balanced eating, rather than replacing meals or being used reactively.
In practice, I typically encourage clients to focus on three balanced meals per day within a roughly 12-hour eating window, with each meal including a source of protein alongside fibre-rich carbohydrates and healthy fats. This approach supports satiety, steady energy, and more stable blood glucose levels across the day.
From a physiological perspective, meals that combine protein, fats, and fibre slow gastric emptying and the absorption of glucose, resulting in a more gradual glycaemic response. This can reduce the need for frequent snacking and support improved concentration and mood regulation.
That said, snacks can play an important role when there are longer gaps between meals. If you are going more than four to five hours without eating, or if you notice dips in energy, focus, or mood, a well-balanced snack may help to maintain blood glucose levels and prevent the activation of the stress response.
In these situations, including a source of protein is particularly important. Protein slows carbohydrate absorption and provides amino acids that support neurotransmitter production. Fibre and healthy fats further enhance satiety and contribute to a more sustained release of energy.
In practical terms, this means aiming for snacks that combine at least two of the following:
For example, pairing fruit with nuts or yoghurt provides a more balanced option than fruit alone. Similarly, oatcakes with a protein-rich topping offer more sustained energy than refined snack foods.
Some simple and realistic snack ideas include:
These options are accessible, require minimal preparation, and provide a combination of nutrients that support stable energy and focus.
It is also important to recognise that not everyone will need snacks. If your meals are well balanced and spaced appropriately, you may find that you can comfortably go from one meal to the next without additional food. The aim is to support your individual needs, rather than following rigid rules.
Keeping a small number of go-to snack options available, particularly during busy or unpredictable days, can help reduce decision fatigue and support more consistent choices. Snacks do not need to be perfect to be helpful. When used thoughtfully, they can support steady energy, improved focus, and a greater sense of calm throughout the day.

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.

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.
