Mixed fruitEating a healthy diet is not just good for your waistline, it's good for your brain too! So make sure you eat your 'Five a Day' of fruit and vegetables. And you can still eat well on a budget.

At the Brain Charity's centre in Liverpool we have healthy cooking classes, and we even have our own Brain Food Café.

Five of the best brain foods

Oily fish

Fish such as salmon, herring, and sardines are a very good source of Omega-3 fatty acids. These healthy fats are essential for the development and maintainance of the brain. Omeega-3 has been shown to help ward off dementia, and as well as that, Omega-3 fatty acids can help with depression, and reduce the risk of diabetes. Our bodies can't make their own Omega-3, so you have to make sure good sources are part of your diet.

Veggie sources of Omega-3

For vegetarians and vegans, alternatives to fish include walnuts, rapeseed oil and linseed oil, and soya-based food.

Nut allegies

If you have a nut allergy, then avocadoes are great to eat for your healthy fatty acids.

Pumpkin seeds

Pumpkin seeds are another good source of the healthy fat Omega-3, and they are good for vitamins and minerals too. This can all help with reducing blood pressure and improving your sleep, both of which are important for your brain.

Blueberries

Blueberries are great for vitamins, and for antioxidants which are good for your heart - and therefore good for your brain. Blueberries have been shown to be good for your memory too.

Avocadoes

Avocadoes are high in healthy, unsaturated fat which helps with healthy blood flow and lowers blood pressure, and are a good source of vitamins and minerals. They even include a type of healthy fatty acid that is good for your nervous system. You might have to keep an eye on the extra calories, but avocadoes are great.

Dark chocolate

Great news: chocolate can be good for you! Dark chocolate is best. Chocolate includes anti-oxidants, it can help reduce blood pressure, and it can reduce inflammation. Chocolate is another good superfood for your memory too. But don't forget to watch out for sugar and those extra calories.
