Health Benefits Beyond Calories
Beyond their low-calorie and high nutrient content, the powerful antioxidants in tomatoes offer specific health benefits that make them a valuable part of a balanced diet. The antioxidant lycopene, in particular, has been a major focus of research.
- Heart Health: Studies suggest that diets rich in tomatoes, specifically those high in lycopene, may be linked to a lower risk of heart disease. Lycopene supplementation has also shown promise in lowering 'bad' LDL cholesterol.
- Cancer Prevention: Lycopene and beta-carotene found in tomatoes may have protective effects against various cancers, including prostate, lung, and stomach cancers.
- Skin Health: The lycopene and other plant compounds in tomatoes may offer protection against sunburn and improve skin health. The high water content also aids in keeping skin hydrated.
- Enhanced Antioxidant Absorption: Interestingly, the body's absorption of lycopene is enhanced when tomatoes are cooked and consumed with a source of fat, such as olive oil. This means processed tomato products like sauces and paste can be excellent sources of this antioxidant.
