This new disease-fighting substance is said to be found in red grapes, whose juice and skin may offer more than just wine. The antioxidant red grapes are contained in the seeds of the fruit. Scientists say that these antioxidant red grapes may offer significant protection against certain types of cancer, heart disease, rheumatoid arthritis, cataracts, and many other chronic and degenerative diseases. Research show that this particular form of antioxidant dietary supplement greatly helps in boosting the immune system and thus aid in preventing the onset of degenerative diseases. Another popular form of antioxidant dietary supplement is Vitamin E. This antioxidant dietary supplement works best when taken with Vitamin C as it seems that both vitamins have synergistic effect when taken in combination. Antioxidants, it seems, have created quite a huge wave in the scientific community that is devoting countless journals and magazine articles about their many benefits. Antioxidants are substances that work on free radicals, or more particularly work to counteract the damaging effects of these harmful oxygen byproducts. It seemed that in most major trials designed to see whether taking extra beta-carotene antioxidant supplements could ward off cancer, beta-carotene didn't do a good job at it. Worse, beta-carotene antioxidant supplements and pills seemed to increase rates of cancer for smokers in two large trials. And so, studies began to look towards other sources of antioxidants as possible antioxidant supplements. More particularly, fresh fruits and vegetables are the richest sources of antioxidant support available. For instance, the antioxidant support Retinol or Vitamin A (or beta-carotene) are found in dark green, yellow, and orange vegetables and fruits. In fact, it is the antioxidant support found in these fruits that protect them from solar radiation damage. Anti Aging Antioxidant Research shows that cells are only allowed so many cell divisions in a human lifetime before they would have to give out. Based on their findings, scientists say that by the time you are 20 years old, most of the cells that make up your body have already used up half of their available cell divisions in their cell lifespan.
