Ask the doctor

Q. My doctor says the Mediterranean diet is not only good for my health in general, but that it is particularly good for my brain. That got my attention. Anything to it?

A. I think there is. The Mediterranean diet is rich in whole-grain bread, root vegetables, green vegetables, fish, poultry, fruit, and olive oil. It includes relatively little red meat, butter, and other foods rich in saturated fats and trans fats. As is often the case with research into a medical question, not all studies come to the same conclusion. But many studies have found that people who regularly adhere to the Mediterranean diet are less likely to develop Alzheimer's disease.
