USANA CellSentials™: Premium Minerals and Antioxidants | USANA Video





Free radicals are still necessary for life, but in order to prevent yourself from developing these diseases, you need to take action in keeping free radicals at a minimum. Fortunately for us, the body has a number of mechanisms to minimize free radical induced damage and to repair the damage which does occur. 

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. That means by the time you are 40, your cells may only have 30 per cent of cell divisions left. This is actually the reason behind the physical changes that goes on not only inside but outside the body as you approach your years. 

The Top 20 list of antioxidants published in the Journal of Agricultural and Food Chemistry shows the ranks of the capacity of berry foods, fruits, and vegetables to interfere with or prevent oxidative processes where free radicals are formed. Ronald L. Prior, a USDA nutritionist and research chemist based in Little Rock, Ark explains that berry antioxidants were ranked according to their total antioxidant capacity. 

Scientists point out that this might be because consuming antioxidant fruits in food may provide a combination of lesser-known but potent antioxidant substances, which may afford greater effect than that of any single nutrient or individual antioxidant supplement. In a recent issue of the Journal of Nutrition, the total antioxidant content of several antioxidant fruits, including fruits, berries, vegetables, cereals, nuts, and legumes, was analyzed. 

As mentioned earlier, many foods with high antioxidant levels are vegetables and fruits. Tomatoes, broccoli, cauliflower, peppers - these are but a few of the many antioxidant foods out there. However, you should note that not all vegetables are high sources of antioxidant foods. Some vegetables or fruits may have lesser amount or concentration of antioxidant foods as other vegetables. 

Now, I'm sure you know what free radicals are. This is probably not the first time you've heard about it. But for the sake of those who have only just stumbled on the term, free radicals are those unstable chemical substances that are highly reactive and are by-products of the process of oxidation in the body.
