When your cells finally use up their naturally allotted cell divisions, the result is death. It is an inevitable occurrence and there's not stopping it. There is however a way to retard it though. Recent research has found a way to give you new hope, a way to rejuvenate and extend the lifespan of cells. Because it is the nature of free radicals, which is basically an atom with an unpaired electron, to achieve stability, they will try to do so by capturing the needed electron from other molecules. When the free radicals steel electrons from a stable molecule, that molecule will become a free radical itself, beginning a chain reaction. Hence, this aspect of antioxidant antiaging therapy focuses more on extrinsic aging, which is the aging process compounded by externally caused factors. On the other hand, the programmed theories are primarily concerned with the genetics of how long and how efficient our cells can maintain optimum health. Prior and his colleagues used the most advanced technologies available to tabulate antioxidant levels in more than 100 different types of berry fruits, vegetables, nuts, and spices. The Top 20 list includes small red beans (dried), wild blueberry, red kidney beans, pinto beans, blueberry (cultivated), cranberry, artichokes (cooked), blackberry, prunes (dried plums), raspberry, strawberry, red delicious apples, Granny Smith apples, pecans, sweet cherries, black plums, russet potatoes (cooked), black beans (dried), plums, and gala apples. Since then, scientists and researchers have sought to understand the body's oxidation process and free radicals contribute in its acceleration. It seemed that these so-called free radicals are rogue oxygen molecules that are highly unstable and which have harmful effects to the body. There is growing evidence that the production of reactive oxygen species (ROS), including free radicals, is behind the aging process and initiation of age-related disease. 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.
