Studies of people who eat a diet that is typical of the Mediterranean region have shown that this type of diet leads to reductions in heart disease as well as forms of cancer. A typical Mediterranean diet has a large amount of fruit, vegetables, whole grain breads and cereals, beans, potatoes and seeds. Olive oil is the main source of fat and there is a daily use of dairy products (such as cheese and yogurt) in low to moderate amounts. The main meats are fish or poultry with rare red meat. Desserts are usually fruits with rare sweets. Wine is also used in low to moderate amounts with meals.
