Vitamins A and E are of nutritional interest because they possess antioxidants and constitute a protective factor against certain degenerative, cardiovascular diseases and cancer. Vitamin D acts in the intestine favoring the absorption of calcium and phosphate.

Unlike other animal foods, fish contains polyunsaturated fatty acids in amounts from 25-45 per cent (percentages based on total fatty acids).
