Cruciferous vegetables & dark leafy greens
Cruciferous vegetables and dark leafy greens have proven brain health benefits. In a very large study in women in their 60s, researchers found that those who ate more leafy greens and cruciferous vegetables--like broccoli, cabbage, kale, and Brussels sprouts--showed less decline in memory, attention, and verbal abilities than women who ate less of those foods. Spinach, kale, chard, and other dark leafy greens are true superfoods, packing in almost 400% of the recommended daily value of vitamin A in just one cup, with healthy doses of vitamin C and E and folic acid as well. All of the foods in this category are fantastic sources of antioxidants.
