Lentils

According to Katz, lentils are full of brainfriendly B vitamin folate, which helps keep your mind sharp as you age, thiamin and vitamin B6, which give you more focus and energy, iron, which is important for cognitive functioning in women during childbearing years, and zinc, which is said to be a memory booster. Silicon Valley has promised us that, someday, little nanobots will act like tiny microprocessors in our brains, helping to make us smarter, Katz says. I say, why wait? We already have a teensy food that does that. Its the lentil, the vegetable kingdoms version of a Lilliputian flying saucer.
