Mediterranean diet
Overview
The Mediterranean diet is a dietary pattern traditionally followed in the Mediterranean region, particularly in countries like Italy, Greece, and Spain. It is characterized by high consumption of fruits, vegetables, legumes, nuts, seeds, cereals, olive oil, and fish, moderate intake of dairy products and wine, and low intake of meat and meat products. The Mediterranean diet is considered one of the healthiest diets due to its association with lower risk of chronic diseases such as heart disease, cancer, and diabetes.

History
The Mediterranean diet has its roots in the dietary patterns of the Mediterranean region dating back to the early 20th century. The diet gained international recognition in the 1950s when American scientist Ancel Keys conducted a study, known as the Seven Countries Study, which found that populations in the Mediterranean region, particularly in Greece and Italy, had lower rates of heart disease compared to other countries. This was attributed to their dietary habits, which were rich in plant-based foods and low in animal products. Learn more about Ancel Keys.
Nutritional Profile
The Mediterranean diet is rich in dietary fiber, antioxidants, and unsaturated fats, particularly omega-3 fatty acids, due to high consumption of fruits, vegetables, whole grains, nuts, seeds, and fish. Olive oil, a staple in the Mediterranean diet, is a source of monounsaturated fats, which are known to be heart-healthy. The diet is also low in saturated fats and trans fats due to limited intake of red meat and processed foods.

Implementation
Implementing the Mediterranean diet involves incorporating more fruits, vegetables, whole grains, legumes, nuts, seeds, and olive oil into your diet, eating fish and seafood at least twice a week, consuming moderate amounts of cheese and yogurt, limiting intake of red meat, and drinking wine in moderation, preferably with meals. It also emphasizes enjoying meals with family and friends, being physically active, and maintaining a balanced lifestyle. Learn more about physical activity.
Criticisms and Controversies
Despite its numerous health benefits, the Mediterranean diet has faced some criticisms and controversies. Some argue that it may not be suitable for everyone due to individual dietary needs and preferences. Others point out that it may be difficult to follow in non-Mediterranean countries due to the availability and cost of certain foods. Moreover, there are concerns about the environmental impact of the diet, particularly the overfishing of certain species of fish. Learn more about overfishing.
