The researchers studied eight different types of fish from the Indus River to see what they are made of and what kind of fats they have. They found that the fish have different amounts of water, ash, protein, and fat. The fat in the fish is mostly monounsaturated, followed by saturated and polyunsaturated fats. The most important polyunsaturated fats in the fish are eicosapentaenoic acid and docosahexaenoic acid. These fish are a good source of healthy fats, which are good for your body.
