Opt for whole grains
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. Achieve this by choosing whole grains, which release glucose slowly into the bloodstream, keeping you mentally alert throughout the day. Opt for 'brown' cereals, wheat bran, granary bread and brown pasta.
Eat oily fish
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. 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. The main sources of oily fish include salmon, trout, mackerel, herring, sardines, pilchards and kippers.
Eat more tomatoes
There is good evidence to suggest that lycopene, a powerful antioxidant found in tomatoes, could help protect against the kind of free radical damage to cells which occurs in the development of dementia, particularly Alzheimer's.
Add vitality with vitamins
Certain B vitamins - B6, B12 and folic acid - are known to reduce levels of homocysteine in the blood. Elevated levels of homocysteine are associated with increased risk of stroke, cognitive impairment and Alzheimer's disease.
Get a blackcurrant boost
Vitamin C has long been thought to have the power to increase mental agility. One of the best sources of this vital vitamin are blackcurrants.
Pick up pumpkin seeds
Just a handful of pumpkin seeds a day are all you need to get your recommended daily amount of zinc, vital for enhancing memory and thinking skills.
Bet on broccoli
A great source of vitamin K, which is known to enhance cognitive function and improve brainpower.
Nuts are a great source of vitamin E along with leafy green vegetables, asparagus, olives, seeds, eggs, brown rice and whole grains.
