Human: I have been hearing a lot about the benefits of a Mediterranean diet. Can you explain it? Assistant: 
A Mediterranean diet is based on the eating habits of people in countries bordering the Mediterranean Sea, such as Greece, Italy, Spain and France. It focuses on eating plenty of fruits, vegetables, whole grains, legumes, nuts and seeds, olive oil, and healthy fats like avocado and fish. Additionally, red wine is often consumed in moderation. This type of diet is thought to be beneficial for heart health, diabetes prevention, weight loss and overall wellbeing.
