Antioxidants and Free Radical Prevention Lecture by Dr Whiting - Maqui Berry





Antioxidants are substances that work on free radicals, or more particularly work to counteract the damaging effects of these harmful oxygen byproducts. 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. 

Such damage, when accumulated, could lead to degenerative conditions. Fortunately, nature has provided us with a system to help control free radicals. Antioxidants are natural enemies of free radicals because one of their functions is to break the chain reaction and destroy free radicals. Therefore, while antioxidants can be found in many fresh fruits and vegetables, it still pays to take antioxidant dietary supplement along with your food. 

These antioxidant enzymes neutralize many types of disease-causing free radicals, ridding the body of their harmful effects. Supplements of these antioxidant enzymes are also available. Usually they are for oral administration in the form of pills or capsules. However, the absorption of antioxidant enzymes in supplement form is minimal at best. 

How antioxidants work is a two-way process. First is the chain-breaking. This is where the antioxidant comes in to break the chain reaction of free radicals turning other molecules into free radicals like them. Chain-breaking is also called Stabilization. The other aspect is more on the preventive side. 

This list of foods contained most of the very rich antioxidant foods as ranked by nutrition scientists at the US Department of Agriculture (USDA) and reported by the University of Alabama website on November 1, 2004. Wild blueberry was narrowly beaten out by the small red bean, which captured the red-blue medal. 

A typical atom is comprised of a nucleus - neutrons, protons, and electrons. Electrons are those negatively charged particles that orbit the cluster of protons in an atom. When there are eight electrons in an orbit, it means that that particular orbit (or shell as it is called) is full which further means the atom is stable.
