Tomatoes are one of the most popular types of produce in America. They are also one of the most nutritious vegetables you can eat. Tomatoes are high in antioxidants like lycopene, beta-carotene, and vitamins C and E. These antioxidant nutrients may help reduce your risk of certain cancers caused by free radicals or oxidative damage to cells, such as prostate cancer and breast cancer. Tomatoes also contain folate, which is important for women who may become pregnant or who are pregnant because it helps prevent birth defects like neural tube defects (NTDs).
