Tea

Yes, caffeine is one reason tea makes the brain-booster list. (FYI: We’re talking about green, black and white teas made from the Camellia sinensis plant, and not those derived from herbs and flowers.) But tea is also chock full of other brain-promoting nutrients that help you think and remember better. One is the calming amino acid theanine, which, in combination with stimulating caffeine, cuts mental fatigue, improves alertness and increases memory.

Teas also contain an abundance of powerful brain-friendly plant antioxidants called catechins. Studies show these special disease-fighting nutrients not only enhance cognition, memory and attention, but some may also decrease depression and mental dysfunction.
