Human: I've been hearing a lot about the Mediterranean diet. Can you tell me what it is? Assistant: 
The Mediterranean diet is based on the traditional eating habits of people in countries bordering the Mediterranean Sea, such as Greece and Italy. It focuses on eating plenty of fresh fruits and vegetables, whole grains, legumes, nuts, and olive oil; moderate amounts of fish, poultry, and dairy products; and limiting red meat and sweets. This diet emphasizes healthy fats, like those found in extra-virgin olive oil, avocados, olives, and fatty fish, which are thought to help reduce inflammation and improve heart health.
