Diet to Promote Memory and Brain Health

The optimal "memory" diet is one that emphasizes plant foods in as close to their natural state as possible.

Plant foods are rich sources of antioxidant vitamins and minerals that counteract oxidation. Green, leafy vegetables contain high amounts of vitamin A, vitamin B12, and folic acid. Insufficient levels of these important vitamins have been shown to cause memory impairment. Sweet potatoes, squash, and other yellow-orange vegetables are rich in beta-carotene. Unprocessed oils and grains and raw nuts and seeds contain vitamin E. Fruits, especially citrus fruits and berries, have high levels of vitamin C. These vitamins help protect the brain as you age.

Reduce your intake of saturated fat and cholesterol by eliminating high-fat dairy (cheese, sour cream, butter, whole milk) from your diet and relegating meat to side dish status a few times a week. Also avoid trans fatty-acids, which are found in margarine, processed oils, fried foods, and most commercially baked goods. And artificial sweeteners—especially aspartame—should be avoided like the plague.

At the same time, make sure you're getting enough of the good fats—omega-3 and omega-6 fatty acids—which are considered essential because they can be obtained only through foods or supplements. Fresh raw nuts and seeds are rich in omega-6 fatty acids, while cold-water fish (salmon, mackerel, herring, sardines, tuna, and trout) and flax are the richest sources of omega-3 fatty acids. I recommend eating salmon or other cold-water fish several times a week, and having one-quarter cup of freshly ground flaxseed daily. For cooking, use extra-virgin olive oil.
