The Mediterranean diet consists of moderate consumption of dairy, healthy fats like olive oil, fish and poultry twice a week, low meat, and high plant foods. It is rich in vitamins and reduces risks of heart disease, cancer, and neurological diseases. First publicized in 1975, numerous studies since have shown it promotes good health and longevity, in contrast to modern high-fat, low-fiber diets. Key aspects include high intake of olive oil, vegetables, fruits, grains, nuts and legumes, along with moderate dairy, poultry and wine, and low intake of red meat and sweets paired with regular exercise.
