Food can improve your brainpower. A study from Rush University in Chicago, US, found that adults who followed a heart-healthy diet reduced their risk of developing Alzheimer's disease by up to 50 per cent compared with those who didn’t. The diet, a hybrid of Mediterranean and DASH (Dietary Approaches to Stop Hypertension), is called MIND (Mediterranean-DASH Intervention for Neurodegenerative Delay) and was developed by researchers who found that people following meal plans designed to curb heart disease and type 2 diabetes also had lower rates of Alzheimer’s.

Berries may decrease neuron loss and improve memory performance.
How often: Twice a week (try them in a smoothie).
3/ Colourful veg
Colours indicate that a food is rich in antioxidants, which can help protect your neurons from age-related decay.
How often: Once a day.
Try: Packing a variety of veg into this peanut noodle salad.
Leafy greens are rich in folate, which researchers have linked to slower rates of brain decline.
How often: A salad a day.

Walnuts, almonds, pecans, hazelnuts and pistachios are rich in fibre, fat and vitamin E (walnuts are the best for your mind).

8/ Red wine and dark red juices
In moderation, red wine can help ward off brain decline, thanks to its antioxidants. Unsweetened grape and pomegranate juices can do the job, too.
How often: No more than a glass of wine a day.
9/ Oily fish
The omega-3 fats in oily fish such as salmon, tuna, mackerel and anchovies are essential for the maintenance of good brain health.

The B vitamins and vitamin E in wholegrains such as wholewheat bread, oats, wild rice and quinoa may help decrease your risk of Alzheimer's by ridding the body of compounds linked to brain damage.
