For a fatty liver diet, nutritional habits that support metabolism and improve overall health should be adopted. The principles of the Mediterranean diet are especially recommended; this includes promoting the consumption of sources rich in monounsaturated fatty acids like olive oil, fish, and plenty of fresh vegetables. Refined sugar, processed baked goods, trans fats, excessive saturated fats, and packaged foods containing preservatives should be strictly avoided. Fresh and natural foods should be the primary choice.
