The Mediterranean diet is a way of eating based on the traditional foods of countries around the Mediterranean Sea. It emphasizes plant-based foods, healthy fats, and overall eating patterns. A focus on vegetables, fruits, whole grains, beans, nuts, and seeds characterizes the diet. Olive oil is the main source of fat, and fish and other seafood are also a key part of the diet. Foods are prepared with herbs and spices instead of sauces and gravies. Red wine is consumed in moderation, with meals, but not every day. Little or no red meat is consumed, and instead, poultry, fish, or beans are eaten. Little or no sweets, sugary drinks, or butter are included.
