5. MIND Diet
The MIND a mix of DASH and the Mediterranean diet—is supposed to help protect the brain and prevent Alzheimer’s disease, though much more research is needed to determine whether it really helps curb brain decline. People are encouraged to eat from 10 brain-healthy food groups: green leafy vegetables, all other vegetables, nuts, berries, beans, whole grains, fish, poultry, olive oil and wine. They are also told to avoid foods from five food groups: red meats, butter and stick margarine, cheese, sweets and fried or fast food.
6. TLC Diet
Tied for fifth place, the TLC (Therapeutic Lifestyle Changes) diet is meant to help people cut down on high cholesterol. Adherents cut down on fat overall, especially saturated fat. They are also encouraged to eat more fiber.
