Although the vitamin C contained in cooked or processed tomatoes (tomato sauce, tomato juice and canned tomatoes) will be destroyed, the content of lycopene can be increased several times, and its antioxidant function is stronger. Therefore, nutritionists strongly recommend tomatoes to people and advise people to eat them in large quantities. Lycopene, an antioxidant component in tomatoes, has been proved to reduce the chances of arterial obstruction and cardiovascular diseases. After lycopene is heated and cooked into tomato sauce, its antioxidant effect can be improved. Most canned ketchup also contains vitamins A, C and fiber.
It is advisable to heat tomato sauce with iron utensils (such as adding it to pasta). Acidic components will dissolve a small amount of iron and provide additional iron supplement.
