What we eat can have an impact on our ability to think clearly, our energy levels and our mood. Making healthier food choices will improve physical and mental health, fitness and your overall sense of well-being.

 6 tips to improve well-being through diet

Eat regularly

If your blood sugar drops you might feel tired, irritable and depressed. Eating regularly (3 balanced meals) and choosing foods that release energy slowly will help to keep sugar levels steady. Slow-release energy foods include pasta, rice, oats, wholegrain bread and cereals, nuts and seeds.

Stay hydrated

Dehydration can affect your ability to concentrate, think clearly and increase fatigue. 

Eat 5 pieces of fruit and veg

Vegetables and fruit contain a lot of the minerals, vitamins and fibre we need to keep us physically and mentally healthy. 

Look after your gut

Your gut can reflect how you are feeling emotionally. When stressed and/or anxious, our gut can respond by slowing down or speeding up. Plenty of fibre, fluid and exercise can help support healthy digestion.

Manage your caffeine intake

Caffeine is a stimulant, which means it will give you a quick burst of energy.  Caffeine can also leave you feeling nervous, moody and can keep you up all night.

Eat the right fats

Not all fats are bad. Your brain needs fatty acids (such as omega-3 and -6) to keep it working well. Healthy fats are found in oily fish, poultry, nuts, olive and sunflower oils, seeds, avocados, milk, yoghurt, cheese and eggs.


Keeping a regular food diary can help to increase your self-awareness of your diet and in turn improve your well-being.

It might take you time to get used to a new eating pattern. Make changes slowly and give yourself time to adjust. Write down what you eat and make notes about how you’re feeling in the hours and days thereafter. Over time, you might work out how particular foods make you feel and the impact on your energy or mood.
