Tomatoes contain a pigment called lycopene that gives the plant its red color. Lycopene is a very powerful antioxidant, so consuming
tomato-based products such as canned tomatoes, tomato sauces, tomato soup or juice and even ketchup will provide your body with antioxidant activity. Lycopene is also present in watermelon in highly concentrated quantities. Additionally, lycopene is available as a dietary supplement.
Lutein is a carotenoid type antioxidant found in green leafy vegetables that has been recently implicated in preventing or lessening the severity of macular eye degeneration. It too is available as a supplement.
Citrus fruits such as oranges, grapefruit, lemons and limes are extremely high in antioxidant activity because they contain natural substances such as carotenoids, flavonoids, terpenes and coumarins, all of which offer good free radical protection.
Certain members of the berry family contain powerful antioxidants as well including cranberries, blueberries, elderberries, acai, black currants and grapes, all of which contain high concentrations of anthocyanins, which possess high antioxidant activity. Grapes also contain another powerful antioxidant called resveratrol that is getting a lot of interest as of late. Resveratrol is the component of red wine that is thought to be the healthy component that, along with the abundant flavonoid polyphenols also present, helps contribute to the fact that the French suffer a relatively low incidence of coronary heart disease despite having a diet rich in saturated fats. More research is necessary to prove this correlation.
When it comes to antioxidant activity, the described compounds work more powerfully as a group rather than separately. Combining the vitamins, minerals, specialty supplements and foods provide a far greater benefit as a result of the antioxidants working synergistically together. It is not necessary to take all of the aforementioned products to get this beneficial effect. You can pick and choose those that fit into your dietary habits and supplement regimen.
It is impossible for us to avoid all damage by free radicals because they arise both inside and outside of our bodies. By utilizing the protective effect of antioxidants, however, one can feel comfortable with the fact that research shows that people who eat a diet rich in antioxidants, fruits and vegetables are less likely to get certain diseases.
Individuals with special dietary requirements and individuals with special needs often have elevated oxidative stress. There are laboratory markers which measure levels of antioxidant compounds present in the body. Talk to your doctor about appropriate testing and subsequent supplementation with antioxidants.
