Human: I've been hearing a lot about the Mediterranean diet lately. What is it and is it healthy? Assistant: 
The Mediterranean diet focuses on eating whole grains, fruits, vegetables, legumes, nuts, and olive oil as main sources of food. It also encourages consuming fish and poultry, but limiting red meat intake. Additionally, the Mediterranean diet emphasizes using herbs and spices to add flavor to dishes instead of adding salt or other condiments. Lastly, it includes moderate amounts of alcohol in moderation. This type of diet has been linked to numerous health benefits including lower risk for heart disease, diabetes, and some types of cancer.
