Antioxidant Support Free radicals are a natural consequence of oxidation - that vital process that allows our body to function normally. Free radicals actually play an important role in a number of biological processes, some of which are necessary for life, such as intracellular killing of bacteria by neutrophil granulocytes. Oxidative stress is a process which many a scientist has linked with the development of chronic and degenerative diseases such as heart disease and cancer. Antioxidant fruits may be plain fruits, cereals, and vegetables. Some antioxidant fruits may also be taken in dried, powdered forms, like dietary supplements or pills. The group of researchers who conducted the study say that a compound extracted from the seeds of red grapes called Activin (tm) is that substance with powerful antioxidant red grapes properties. Because of its apparent powerful benefits, Activin was dubbed as the "super" antioxidant red grapes. Although antioxidants cannot completely rid our bodies of free radicals, they can however work to retard or minimize the damage caused. Antioxidants block the process of oxidation by neutralizing free radicals. By neutralizing, they themselves become oxidized. For this reason, our bodies are always in need of a constant source of antioxidants. Blueberries and cranberries are usually the fruits that are often touted by nutrition scientists as the top antioxidant rich foods. In the vegetable variety, russet potatoes, red beans, and red cabbage are topping the list as well. However, there are also other fruits and vegetables that may contain more essential benefits to our health. The result is a rapid chain reaction which when left unattended can lead to various degenerative diseases such as heart disease, stroke, cancer, Alzheimer's disease, Parkinson's disease, memory loss, etc. Natural antioxidants are primarily derived from plants. The human body cannot produce its own supply of natural antioxidants; that is why we have to depend solely on our diet to get the amount of antioxidants our body needs.
