Lycopene is an antioxidant that has been shown to reduce prostate cancer. Additionally, lycopene can increase HDL (healthy cholesterol) and reduce LDL (bad cholesterol). Some studies have shown a relationship between lycopene in tomatoes and the reduction of the presence of oxidized LDL, which can contribute to the plaque on the walls of the arteries.
Tomatoes are also an excellent source of vitamin A, which is an essential component for normal vision and immune function. They are also a very good source of vitamin K, which assists in blood clotting and potassium, which can help to reduce blood pressure.
