Fish is one of the healthiest aniumal food products. Especially when it is rich in oils, it is the best dish for the protection of the heart. On the other hand, all its benefits could vanish, if it is cooked in fats or in a way that destrys all its nutrients, such as when overcooked. Grilling fish is a wonderful idea, since in only a few minutes you can taste all its flavor and aroma, without any additions apart from a few drops of oil or some salt. In addition, its content in calories does not increase as it does when it is fried.
