Ever notice how a hectic day at work or a sleepless night seems to throw off your whole eating pattern? In my practice, I often meet people with diabetes who find it harder to stay steady when stress climbs. It is not just a feeling of fatigue: the stress hormone cortisol can influence how your body uses and releases sugar, which can make everyday life feel more challenging.
The science behind stress and cortisol
When you meet a stressor, your body releases cortisol from the adrenal glands. This prepares you for a “fight or flight” response by mobilising energy stores, including prompting the liver to release more glucose. In people without diabetes, insulin usually deals with that extra sugar. When insulin does not work as efficiently, the effect can last longer, which is why stress is often discussed alongside diabetes. Research suggests that chronic stress is associated with poorer day-to-day wellbeing for people living with diabetes, which is why looking after stress is part of the bigger picture.
Food ideas that may support you
You cannot remove stress from your life, but you can choose foods that support your body while you are under pressure. Meals that include protein and fibre tend to feel more steadying than a quick sugary fix. Some nutrient-rich options I often discuss:
- Oily fish: salmon, mackerel and sardines provide omega-3 fats as part of a balanced pattern.
- Leafy greens: spinach, kale and chard supply magnesium.
- Legumes: lentils, chickpeas and beans give plant protein and fibre.
- Wholegrain oats: a slower-release carbohydrate that keeps you full.
- Nuts and seeds: almonds, walnuts and pumpkin seeds supply healthy fats and magnesium.
- Fermented foods: kefir, yoghurt and sauerkraut may support the gut, which research suggests is connected with how we respond to stress.
Studies in this area are still emerging, so I see these as helpful additions to a balanced diet rather than quick fixes.
Practical everyday ideas
- Start the day with oats topped with walnuts and berries.
- Swap a sugary snack for almonds and a piece of fruit when stress cravings hit.
- Include oily fish a couple of times a week; a quick grilled salmon fillet is easy.
- Finish the evening with a small serving of kefir or natural yoghurt.
- Drink water through the day, since thirst can feel like tiredness or cravings.
Lifestyle factors alongside food
Food is only one piece of the puzzle. Regular movement, enough sleep and mindfulness practices such as deep breathing or short meditations are all linked with lower stress levels. Even a ten-minute walk after a stressful meeting can help you feel calmer.
Support that fits you
As a UK-registered nutritionist, I help you weave stress-friendly foods into your usual meals. I work alongside your doctor, who looks after your medication and wider diabetes care, so my focus stays on food. You may also like to read about working with a diabetes nutritionist or consider an online consultation where we can discuss your situation.
When you have eaten a well-balanced dinner after a high-pressure workday and still feel unsettled, it becomes clear that stress needs a more personal approach than standard food rules.
