Legumes
These protein powerhouses contain folate, which helps to protect the brain. Legumes (like lentils, beans and peas) are also a good source of slow-digesting glucose, providing the brain with a steady source of fuel. Toss them in a salad, make them the star of the show in a soup or incorporate into a healthy Buddha bowl. Easy peasy.
Olive Oil
Veggies, meats, salads, heck, even cakes—is there anything olive oil can’t do? Apparently not. “Olive oil contains polyphenols, powerful antioxidants that can prevent and possibly reverse disease and age-related memory loss,” says Rumsey. Drizzle away.
