It’s Brain Awareness Week this week (12th-18th March) so we wanted to focus this week on brainpower, and the significant part nutrition plays to keep your brain health.
Eating well is good for your mental as well as your physical health. But which foods are particularly important to boost your brainpower and keep your grey matter happy and healthy?
Whether you want to optimise your nutrition during study 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 Alzheimer’s’ or dementia, paying attention to what you eat gives you the best chance of getting all the nutrients you need for cognitive health and brainpower.
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 with a low-GI, which release glucose slowly into the bloodstream, keeping you mentally alert throughout the day.
To help you boost your brainpower, opt for ‘brown’ wholegrain cereals, granary bread, rice and pasta.
2. Oily fish
Eating oily fish such as salmon or trout 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 for brainpower 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 have been 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
Research has suggested that eating blueberries may help boost short-term memory
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 and veg which contain the same protective compounds.
4. Tomatoes
There is good evidence that suggests 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.
Cooking tomatoes releases more lycopene so why not enjoy a healthy serving of tomatoes with a little olive oil to optimise absorption and boost that brainpower.

5. Eggs
We all know how delicious and versatile eggs are but did you know they may also help delay brain shrinkage?
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.
Boost your brainpower by opting for B-rich foods like eggs, chicken, fish and leafy greens.

6. Blackcurrants
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 is blackcurrants. Others include red peppers, citrus fruits such as oranges and broccoli.

7. Pumpkin seeds
May help enhance memory and boost mood and brainpower
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 a 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
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 these delicious recipes from the BBC Food website butternut soup with crispy sage, pearl barley & sage risotto and veal escalopes wrapped with prosciutto, sage & lemon.
10. Nuts
May help protect healthy brain function
A study published in the American Journal of Epidemiology suggests that a good 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 ageing process and helps us process information more effectively.
