No time for crossword puzzles? A B vitamin could help keep you sharp. Dutch scientists found that folic acid may improve your memory. The researchers say that people who got 800 micrograms (mcg) of folic acid every day for 3 years exhibited memories that were 5 to 7 years younger than those who didn’t. A lack of folic acid may contribute to atrophy of the hippocampus, a part of the brain that plays a major role in memory, says study author Jane Durga, Ph.D. To get your daily dose of folate, just toss a handful of tender amaranth (chowli) or baby spinach into any rice, noodle or pasta dish. Stir fresh, raw leaves into cooked grains or noodles soon after draining the pot, and the heat wilts them for you. Every cup adds 15 per cent of your daily requirement of the folic acid. Other good sources of the B vitamin are bengal gram, colocasia, cluster beans (guar), peanuts.
