Another high-quality source of protein is fish. Both the American Diabetes Association and the American Heart Association recommend that you include fish in your meal plan two or three times a week. Besides being a great source of protein, fish contains anti-inflammatory fats called omega-3s. These healthy fats help prevent diseases, such as cancer and heart disease. They also help lower LDL (the bad cholesterol) and raise HDL (the good cholesterol).
The types of fish that have the most omega-3s are salmon, albacore tuna, mackerel, herring and rainbow trout.
