Eat a Brain-Boosting Diet
Just as the body needs fuel, so does the brain. You probably already know that a diet based on fruits, vegetables, whole grains, “healthy” fats (such as olive oil, nuts, fish) and lean protein will provide lots of health benefits, but such a diet can also improve memory. For brain health, though, it’s not just what you eat—it’s also what you don’t eat. The following nutritional tips will help boost your brainpower and reduce your risk of dementia:
Get your omega-3s. Research shows that omega-3 fatty acids are particularly beneficial for brain health. Fish is a particularly rich source of omega-3, especially cold water “fatty fish” such as salmon, tuna, halibut, trout, mackerel, sardines, and herring.
If you’re not a fan of seafood, consider non-fish sources of omega-3s such as walnuts, ground flaxseed, flaxseed oil, winter squash, kidney and pinto beans, spinach, broccoli, pumpkin seeds, and soybeans.
Limit calories and saturated fat. Research shows that diets high in saturated fat (from sources such as red meat, whole milk, butter, cheese, cream, and ice cream) increase your risk of dementia and impair concentration and memory.
Eat more fruit and vegetables. Produce is packed with antioxidants, substances that protect your brain cells from damage. Colorful fruits and vegetables are particularly good antioxidant "superfood" sources.
Drink green tea. Green tea contains polyphenols, powerful antioxidants that protect against free radicals that can damage brain cells. Among many other benefits, regular consumption of green tea may enhance memory and mental alertness and slow brain aging.
Drink wine (or grape juice) in moderation. Keeping your alcohol consumption in check is key, since alcohol kills brain cells. But in moderation (around 1 glass a day for women; 2 for men), alcohol may actually improve memory and cognition. Red wine appears to be the best option, as it is rich in resveratrol, a flavonoid that boosts blood flow in the brain and reduces the risk of Alzheimer’s disease. Other resveratrol-packed options include grape juice, cranberry juice, fresh grapes and berries, and peanuts.
For mental energy, choose complex carbohydrates
Just as a race car needs gas, your brain needs fuel to perform at its best. When you need to be at the top of your mental game, carbohydrates can keep you going. But the type of carbs you choose makes all the difference. Carbohydrates fuel your brain, but simple carbs (sugar, white bread, refined grains) give a quick boost followed by an equally rapid crash. There is also evidence to suggest that diets high in simple carbs can greatly increase the risk for cognitive impairment in older adults. For healthy energy that lasts, choose complex carbohydrates such as whole-wheat bread, brown rice, oatmeal, high-fiber cereal, lentils, and whole beans. Avoid processed foods and limit starches (potato, pasta, rice) to no more than one quarter of your plate.
