10 foods to boost your brainpower

Eating well is good for your mental as well as your physical health. But which foods are particularly important to keep your grey matter happy and healthy?

10 foods to boost your brainpower

Whether you want to optimise your nutrition during exam season or simply want to stay sharp in your next work meeting, paying attention to your diet can really pay off. Although there is no single 'brain food' that can protect against age-related disorders such as Alzheimers' or dementia, and there are many other medical conditions that can affect the brain, paying attention to what you eat gives you the best chance of getting all the nutrients you need for cognitive health.

Eating a healthy, balanced diet that includes these 10 brain-boosting foods may help to keep your memory, concentration and focus as sharp as it can be.

1. Wholegrains

May help improve concentration and focus

Like everything else in your body, the brain cannot work without energy. The ability to concentrate and focus comes from an adequate, steady supply of energy in the form of glucose, in our blood, to the brain. Achieve this by choosing wholegrains which have a low-GI, which means they release glucose slowly into the bloodstream, keeping you mentally alert throughout the day. Opt for 'brown' wholegrain cereals, granary bread, rice and pasta.

2. Oily fish

May help promote healthy brain function

Essential fatty acids (EFAs) cannot be made by the body which means they must be obtained through diet. The most effective omega-3 fats occur naturally in oily fish in the form of EPA and DHA. Good plant sources include linseed (flaxseed), soya beans, pumpkin seeds, walnuts and their oils. These fats are important for healthy brain function, the heart, joints and our general wellbeing. What makes oily fish so good is that they contain the active form of these fats, 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. Low DHA levels may be linked to an increased risk of dementia, Alzheimer's disease and memory loss whilst having sufficient levels of both EPA and DHA is thought to help us manage stress and helps make the good mood brain chemical, serotonin. If you're vegetarian or vegan, you may wish to add seeds like linseed and chia to your diet, or consider a plant-based omega-3 supplement. If you are considering taking a supplement speak to your GP first.

3. Blueberries

May help boost short-term memory

Fresh blueberries

Evidence accumulated at Tufts University in the United States suggests that the consumption of blueberries may be effective in improving or delaying short-term memory loss. They're widely available, but you can also look out for dark red and purple fruits, like blackberries, and veg that contain the same protective compounds called anthocyanins.

4. Tomatoes

May help prevent free radical damage

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 that occurs in the development of dementia, particularly Alzheimer's. Favour cooked tomatoes and enjoy with a little olive oil to optimise absorption and efficacy.

5. Eggs

May help delay brain shrinkage

Two eggs cracked into a bowl and whisked

Certain B vitamins – B6, B12 and folic acid – are known to reduce levels of a compound called homocysteine in the blood. Elevated levels of homocysteine are associated with increased risk of stroke, cognitive impairment and Alzheimer's disease. A study of a group of elderly patients with mild cognitive impairment found that after two years of intervention with high doses of B6, B12 and folic acid there was significantly less brain shrinkage compared to a subset given placebo treatment. Opt for B-rich foods like eggs, chicken, fish and leafy greens.

6. Blackcurrants

May help reduce anxiety and stress

Vitamin C has long been thought to have the power to increase mental agility, and some research suggests that a deficiency may be a risk factor for age-related brain degeneration including dementia and Alzheimer's. Furthermore, interesting studies demonstrate that vitamin C may be useful in managing anxiety and stress. One of the best sources of this vital vitamin are blackcurrants. Others include red peppers, citrus fruits such as oranges and broccoli.

7. Pumpkin seeds

May help enhance memory and boost mood

Richer in zinc than many other seeds, pumpkin seeds supply this valuable mineral which is vital for enhancing memory and thinking skills. These little seeds are also full of stress-busting magnesium, B vitamins and tryptophan, the precursor to the good mood chemical serotonin.

8. Broccoli

May help improve brainpower

Broccoli is great source of vitamin K, which is known to enhance cognitive function and improve brainpower. Researchers have reported that because broccoli is high in compounds called glucosinolates, it can slow the breakdown of the neurotransmitter, acetylcholine, which we need for the central nervous system to perform properly and to keep our brains and our memories sharp. Low levels of acetylcholine are associated with Alzheimer's.

Discover more about the health benefits of broccoli.

9. Sage

May help boost memory and concentration

A sage plant

Sage has long had a reputation for improving memory and concentration. Although most studies focus on sage as an essential oil, it could be worth adding fresh sage to your diet too. Add at the end of cooking to protect the beneficial oils.

Put sage to good use in our healthy recipes, including butternut soup with crispy sage, pearl barley & sage risotto and veal escalopes wrapped with proscuitto, sage & lemon.

10. Nuts

May help protect healthy brain function

A selection of mixed nuts in a bowl on a table

A study published in the American Journal of Epidemiology suggests that an adequate intake of vitamin E might help to prevent cognitive decline, particularly in the elderly. Nuts are a great source of vitamin E along with leafy green vegetables, asparagus, olives, seeds, eggs, brown rice and wholegrains.

Learn more about the health benefits of nuts.

The importance of exercise

Don't forget that as well as a healthy diet, exercise helps to keep our brains sharp. Research suggests that regular exercise improves cognitive function, slows down the mental aging process and helps us process information more effectively.

Brainpower supplements

Although research linking diet and dementia is still in its infancy, there are a few important relationships between nutrients and brain health that are worth exploring. Having a nourishing, well rounded diet gives our brain the best chance of avoiding disease. If your diet is unbalanced for whatever reason, you may want to consider a multivitamin and mineral complex and an omega-3 fatty acid supplement to help make up a few of the essentials. If you are considering taking a supplement it is best to discuss this with your GP or qualified healthcare professional.

Professor David O Kennedy published a book in 2014 called Plants and the Human Brain. In his book he summarizes the last 15 years of research into cognitive nutrition, including the work he's done with colleagues at the Brain Performance Nutrition Research Center at Northumbria University. It's a great read and a good guide to what sorts of herbs and other plants to include in our weekly diet and it is all based on hard science rather than mere assertion or trendy but unsubstantiated beliefs.

I love this topic as I have been reading all about brain function and natural cognitive enhancers. I am currently using a product from brainfunctionbooster.com which is based more of plants and herbs. Keen for more articles on improving brain power.

When I have a glut of tomatoes, I make something the French call Concassé. Onions, lightly fried, but not browned, and tomatoes added - with basil or garlic if you wish - and cooked lightly. This makes a great base for soups, stews, ratatouille - all sorts of dishes - even a pizza sauce, if you boil it down further. Yummy.

Tomatoes - does that include tinned? And what about passata? And while we are at it, are frozen veg as good [or very nearly] as fresh? I'm particularly thinking of green veg like peas, broad beans, green beans. Fresh peas are a seasonal rarity, so are broad beans and green beans in supermarkets are often rather tired after their long trip from Kenya.

Hi there, yes it does include tinned tomatoes - two tinned tomatoes equal one portion of your five-a-day too. Frozen fruit and vegetables are great options and definitely count.Many thanks,The Good Food team
