Tomatoes are high in the antioxidant vitamins beta-carotene, vitamin C and vitamin E, as well as the carotenoid lycopene. This means that tomatoes are helpful in preventing heart disease and cancers. Tomatoes are also high in potassium but very low in sodium which means they help combat high blood pressure and fluid retention.
Unlike some other canned foods, canned tomatoes retain most of their nutrients. In fact, cooked or canned tomatoes contain more lycopene than raw tomatoes. If buying canned tomatoes choose varieties without added sodium.
