Brain Foods-- Foods to keep your memory intact:

Blueberries, Strawberries and Spinach act as brainboosters
What makes these foods so potent?

The above have been shown to protect brain cells from the onslaughts of ageing
Blueberries (Jamun as commonly known in India) and strawberries are rich in anthocyanins, formidable antioxidants in deep red and purple pigments.
Studies suggest anthocyanins may protect the neurons ability to respond to chemical messengers; they also seem to discourage blood clots from forming.
Spinach is a antioxidant powerhouse, bursting with betacarotene, vitamin C and folic acid. All three foods contain other compounds that keep blood vessels supple and help transport nerve impulses more efficiently.
These substances almost certainly get their oomps from teamwork, which is why researchers advise eating the foods rather than popping a supplement made from them
