Foods to boost your brainpower #(1)

Like everything else in your body, the brain cannot work without energy. The ability to concentrate and focus comes from the adequate, steady supply of energy - in the form of glucose in our blood to the brain.

Opt for 'brown' cereals, wheatbran, granary bread and brown pasta

Essential fatty acids (EFAs) cannot be made by the body and must be obtained through diet. The most effective omega-3 fats occur naturally in oily fish as EPA and DHA. Good sources include linseed (flaxseed) oil, soya bean oil, pumpkin seeds, walnut oil and soya beans. They are good for healthy brain function, the heart, joints and general wellbeing. Oily fish contains EPA and DHA in a ready-made form, which enables the body to use it easily. The main sources of oily fish include salmon, trout, mackerel, herring, sardines, pilchards and kippers.
