If you don’t drink enough fluid, you may find it difficult to concentrate or think clearly. You might also start to feel constipated (which puts no one in a good mood).
Vegetables and fruit contain a lot of the minerals, vitamins and fibre we need to keep us physically and mentally healthy.
Eating a variety of different coloured fruits and vegetables every day means you’ll get a good range of nutrients.

Healthy gut foods include: fruits, vegetables and wholegrains, beans, pulses, live yoghurt and other probiotics.

Protein is in: lean meat, fish, eggs, cheese, legumes (peas, beans and lentils), soya products, nuts and seeds.
Whatever your diet, why not do some research into other foods that contain protein, and find something new to try? For ideas on healthy recipes, visit NHS Choices.

Caffeine is in: tea, coffee, chocolate, cola and other manufactured energy drinks.

Healthy fats are found in: oily fish, poultry, nuts (especially walnuts and almonds), olive and sunflower oils, seeds (such as sunflower and pumpkin), avocados, milk, yoghurt, cheese and eggs.
