1. Spinach. At only 40 calories a cup, a serving of spinach contains almost half your daily requirement of folic acid, an essential nutrient for cell growth, blood production, and preventing memory loss. And spinach is one of the most nutrient-dense foods available—just one cup of spinach also contains all your body’s daily requirements of vitamins A and K, plus most of the folate and manganese you need each day too. These nutrients improve brain function and slow down the effects of premature aging by preventing the negative effects of oxidation on the brain. Spinach is also rich in iron, as well as lutein, which promotes healthy eyesight.
Smart Tip: Try replacing iceberg lettuce with spinach leaves in your next dinner salad, or add fresh spinach to an omelet.
2. Oatmeal. As a strong source of insoluble fiber, oatmeal provides a stable energy that helps your brain maintain consistent focus and concentration. Eating oatmeal can also slow down the digestion of starch, reducing the frequent spikes in blood sugar that usually occur after a big meal. The iron, magnesium, and zinc in oatmeal encourage cell growth and can increase metabolism and regulate blood sugar. To get the maximum nutritional benefits, avoid the instant pre-flavored packets, which are loaded with sugar, and stick with the plain, slower-cooking kind—it still cooks up in the microwave in just 2 or 3 minutes.
Smart Tip: Turn up the flavor naturally by preparing oatmeal with low-fat milk and topping it with fresh blueberries or banana slices.
3. Fish. Many studies have shown that eating oily fish rich in omega-3 fatty acids can boost memory, concentration, and mental acuity. Omega-3 acids also appear to strengthen the brain’s synapses that are directly related to learning and memorization. And if that’s not reason enough to eat more fish, the omega-3 fatty acids also help slow down mental cognitive decline.
Smart Tip: Watch mercury levels when choosing fish, and consider wild salmon, albacore tuna, and mackerel, which all contain omega-3s with minimal environmental contaminants.
4. Walnuts. Eating just a handful of these nuts every day can prevent the decline of cognitive and motor function, increase brain resiliency, and improve cell functioning. Walnuts are loaded with protein and omega-3 fatty acids that balance the unstable neurotransmitters that can cause depression and other mood swings.
Smart Tip: Sprinkle a handful of chopped walnuts on salads or fill a travel container for a healthy on-the-go snack. You’ll feel full longer, reducing the temptation to binge between meals.
5. Berries. Many types of berries, especially blueberries and strawberries, contain flavonoids, which have been linked to brain cell
growth and improved memory. Berries with the darkest, richest colors offer the most nutritional value. Eat the real thing to reap the benefits, and avoid anything that contains “berry flavoring.” The antioxidants, vitamin C, and anti-inflammatory properties in berries have been shown to preserve brain function and are a factor in the prevention of dementia.
Smart Tip: Sprinkle berries on salads, cereal, or yogurt, or make yourself a fresh berry fruit smoothie.
6. Yogurt. Widely known as a top calcium source for bone development and strength, yogurt also contains enough protein and carbohydrates in just one serving to keep both the body and the brain energized throughout the day. Yogurt also contains amino acids that encourage the production of neurotransmitters, and enough vitamin B to encourage—along with the protein—the growth of brain tissue while slowing down the aging process.
Smart Tip: Eat yogurt topped with berries for breakfast or lunch, or if you’re having a salad, nix the bottled dressing and make your own by mixing a quarter of a cup of plain nonfat or low-fat yogurt with fresh herbs.
7. Eggs. These low-calorie, nutrient-dense wonders are rich in protein as well as choline, an important nutrient that helps regulate the brain and nervous system by acting as a messenger between muscles and nerves. If you’ve been avoiding eggs because you’re worried about your cholesterol, take note: Numerous research studies have shown that eating eggs as part of a healthy diet is not a contributing factor to heart disease. The nutrients in eggs also increase memory development and aid in concentration. Another plus? Egg yolks contain lutein, which has been shown to improve eye health.
Smart Tip: Enjoy an egg and spinach omelet for breakfast, lunch, or dinner.
