Plants are where we get most of our foods and our medicines, relying on them almost entirely for developing our bodies to their full potential and at the same time reducing the causes of degenerative diseases. Recently, scientists have discovered the substance responsible for many of the health benefits we've been receiving from plants. It seemed that the more free radicals you have in your body, the faster the aging process becomes. Free radicals are harmful, unstable substances that develop after oxidation, a naturally occurring process of the body. Free radicals are not harmful in themselves. In fact, they can be beneficial. The only problem is they do not distinguish between healthy and harmful molecules so that there is a great possibility that they would also "attack" your other healthy cells, causing massive cellular damage, tissue damage, and eventually resulting in a chronic disease or disorder, such as aging. You probably remember from your old high school days that the human body is composed of many different cells and each cell is composed of many different molecules. Molecules consist of one or more atoms of one or more elements joined together by chemical bonds. A typical atom is comprised of a nucleus - neutrons, protons, and electrons. Scientists have linked free radicals to the development of degenerative diseases, causing massive cell damage that ultimately results in various disorders, such as cancer, Alzheimer's, Parkinson's, rheumatoid arthritis, atherosclerosis, heart disease, and much, much more. By neutralizing free radicals, antioxidants actually prevent the onset of these diseases and at the same time keep the body healthy and strong. 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. According to their findings, the overall best sources of antioxidant fruits under the berry category are dog rose, sour cherry, blackberry, strawberry, raspberry, crowberry, blueberry, and black currant. Free radicals are highly reactive chemical substances that are produced when the body undergoes the process of oxidation. The reason that free radicals are highly reactive is that they lack electrons, which cause them to be highly unstable. To achieve maximum stability, free radicals therefore steal electrons from other molecules around them and in so doing, destroy the cell membranes and weaken the cell.
