Question: Canned fish contains oil in its composition. When it is olive it is specified, but if it is simply reflected "vegetable oil", could it be a fat that is harmful to health? Margarita (Plasencia).
Answer: Canned fish can contain vegetable oil in its composition, being olive oil, rich in monounsaturated fatty acids, sunflower or corn seed oil, rich in polyunsaturated fatty acids, or a mixture of both. In these cases, unsaturated fatty acids dominate, which are beneficial for health, since no harmful oils are used in canned fish.
