Anxiety is something many people experience, especially during busy or stressful periods of life. While nutrition alone cannot cure anxiety, research shows that the foods we eat can play an important role in supporting brain health, stabilising mood, and reducing stress responses in the body.

The brain requires a steady supply of nutrients to produce neurotransmitters such as serotonin, dopamine and GABA — chemicals that help regulate mood, sleep and emotional wellbeing. Eating regularly and including specific nutrients can help support these processes.

Here are some of the best foods to include in your diet to support mental wellbeing and help reduce anxiety.

1. Omega-3 Rich Foods

Omega-3 fatty acids support brain health and may help reduce inflammation and stress hormones. They are particularly important for supporting mood regulation.

Foods rich in omega-3 include:

• Salmon

• Sardines

• Tuna

• Chia seeds

• Flaxseeds

• Walnuts

Aim to include oily fish 2–3 times per week, or plant sources of omega-3 regularly if you do not eat fish.

2. Magnesium-Rich Foods

Magnesium plays a key role in relaxing the nervous system and regulating the body’s stress response. Low magnesium levels have been linked to increased anxiety symptoms.

Good sources include:

• Spinach and leafy greens

• Pumpkin seeds

• Almonds and cashews

• Dark chocolate (70% or higher)

• Whole grains

• Avocado

Adding a handful of nuts or seeds to snacks or meals can be an easy way to boost magnesium intake.

3. Complex Carbohydrates

Carbohydrates help the brain produce serotonin, a neurotransmitter that supports mood and feelings of calm.

Choose slow-release carbohydrates to maintain steady energy levels and avoid blood sugar crashes that can worsen anxiety.

Examples include:

• Oats

• Brown rice

• Quinoa

• Wholegrain bread

• Sweet potato

• Legumes

Starting the day with oats, fruit and nuts is a great way to support stable energy and mood.

4. Probiotic and Gut-Friendly Foods

The gut and brain communicate closely through the gut-brain axis. A healthy gut microbiome may support improved mood and reduced anxiety.

Foods that support gut health include:

• Yoghurt with live cultures

• Kefir

• Sauerkraut

• Kimchi

• Miso

• Fibre-rich vegetables and legumes

Including a variety of fibre and fermented foods helps nourish beneficial gut bacteria.

5. Foods Rich in B Vitamins

B vitamins are essential for energy production and brain function. They also help the body manage stress and support neurotransmitter production.

Good sources include:

• Eggs

• Whole grains

• Legumes

• Leafy greens

• Dairy foods

• Lean meats

Eating regular balanced meals can help ensure consistent intake of these important nutrients.

6. Hydration Matters Too

Dehydration can worsen fatigue, irritability and difficulty concentrating, which can amplify feelings of anxiety.

Simple strategies include:

• Keeping a water bottle nearby

• Drinking water with meals and snacks

• Including hydrating foods such as fruit, vegetables and soups
