Nutrition tips for stress

Erratic eating is a physical stressor in its own right. When blood sugar drops, your body releases cortisol — the same stress hormone triggered by a difficult meeting or a looming deadline. If you're already under pressure, skipping meals adds fuel to the fire.

Aim for three consistent meals a day and don't wait until you're running on empty. Feeling irritable, overwhelmed or unable to concentrate is sometimes just hunger in disguise.

Stress triggers cravings for sweet, high-carb foods — it's a genuine physiological response, not a lack of willpower. But sugary foods cause rapid blood sugar fluctuations that amplify anxiety and irritability, making a stressful day feel harder than it needs to.

Slow-release carbohydrates keep blood sugar stable, which directly helps keep your stress response calmer. On a difficult day, reaching for oats, wholegrain bread or lentils instead of a biscuit is one of the most practical things you can do.

If the craving wins — a small piece of dark chocolate is one of the better options. It satisfies the urge without a heavy sugar hit.

Your gut and brain are in constant two-way communication, and what you eat directly affects your ability to handle stress. A varied diet — with a wide range of plant foods, healthy fats and fermented foods — supports both gut health and the brain’s ability to regulate mood and emotions.

Variety is key. The more diverse your diet across the week, the better. Include plenty of vegetables, wholegrains, lentils and beans, nuts and seeds, oily fish and plain yoghurt. These foods work together to support a healthy gut microbiome and keep your stress response better balanced.

Watch caffeine and alcohol

Caffeine raises cortisol levels. On a calm day this is manageable — on an already stressful day it amplifies the physical stress response, increasing feelings of anxiety and tension. Try to keep it to mornings and notice whether it's making things feel sharper or just more frantic.

Alcohol feels relaxing short-term but disrupts sleep overnight, leaving you less resilient the next day. Stress and poor sleep compound each other quickly. On high-pressure weeks it's worth being more mindful of both than usual.

Herbal teas — particularly chamomile and peppermint — are a genuinely calming afternoon swap.

Try not to eat on the run

When you eat while distracted, rushed or anxious, you're less likely to notice when you're full and less likely to choose anything nourishing. Eating while stressed tends to mean eating the nearest thing rather than the right thing.

Even five minutes away from your screen to eat lunch makes a meaningful difference — to how satisfied you feel and to your stress levels for the rest of the afternoon. A proper lunch break is one of the most underrated stress management tools available.

When it's not possible — have something genuinely nourishing ready to go. Convenience and quality don't have to be in conflict if you've planned slightly ahead.
