The Mediterranean diet emphasizes whole grains, fruits and vegetables, fish, shellfish, nuts, olive oil, and other healthy fats. It includes very little red meat. This diet has been associated with lower LDL cholesterol, and a reduced risk of cardiovascular mortality, overall mortality, and a reduced incidence of cancer, Parkinson’s, and Alzheimer’s diseases. Neither high protein nor high carbohydrate diets are recommended in the prevention of disease. Intermittent fasting may be beneficial to cognitive functional but lacks strong research evidence, especially when compared to the well-studied Mediterranean diet.
