But food’s benefits for the brain are sometimes overlooked. “The brain needs healthy fats, lean proteins, vitamins and minerals to function properly,” says Howard Fillit, MD, founding executive director and chief scientist of the Alzheimer’s Drug Discovery Foundation (ADDF) and the ADDF’s Cognitive Vitality Program.

Replace butter with healthy fats, such as olive oil, and limit your intake of red meat, instead opting for other lean protein sources including chicken and fish. Here are some of the treatable causes of dementia.
