Tomatoes contain the antioxidant lycopene. The red ones are the best. Studies have show that having more lycopene in you diet decreases your risk of all types of cancers including skin, lung, prostate, bladder and stomach cancers and also reduce the risk of coronary artery disease. How much? 22mg a day which is about 1 glass of tomato juice or 8 little tomatoes. You can also get the same benefits from watermelon, grapefruit, guava, papaya. So go crazy adding tomatoes sauce to everything…lol….but remember most tomato products have too much of sodium so look for low sodium tomatoe products.
