Medical and research teams are studying the aging process and trying to find a preventive or treatment for the aging process. Antioxidant therapy is in the forefront of many of the research projects. Antioxidants have been shown to have the ability to slow the aging process, as well as help to prevent many diseases that are associated with aging. An understanding of the free radical theory is necessary for anyone that wants to start any type of anti-aging treatment with antioxidants.
In simple terms, free radicals are molecules created during the normal process of metabolism that are considered unstable because they are missing an electron in their outer shells. These free radical molecules seem to attach most readily to electrons in fat molecules. As we get older the human body produces more and more of these free radicals and these molecules can damage the cells around them by stealing an electron from the surrounding cells leaving them vulnerable to diseases commonly associated with the aging process.
Since over 40 percent of the total calories in the typical American diet is derived from fat it not difficult to see how we might be exposed to extensive damaging free radical activity. Antioxidants are able to stabilize these free radicals by pairing up or binding with the free radicals thus inhibiting them from damaging the adjacent cells.
Anti aging vitamins that have antioxidant properties actually include several different kinds of vitamins. Some of the more common antioxidants include Vitamin A, Vitamin B, Vitamin E, Selenium, Beta Carotene, Lycopene, L-Glutathione, Vitamin D, and Green Tea. The vitamins A, D, E, and K are all fat-soluble vitamins and are stored the liver and in the fat cells of the human body so an overdose is possible. These vitamins are extremely important in anti aging therapy but you must not take more than the recommended doses. Water-soluble vitamins are not stored in the body so the chance of an overdose is highly unlikely.
Many antioxidants can be found in many of the foods we consume every day. Some of these foods include berries, apples, many different types of vegetables, fish, red meats, chicken and eggs are all sources of varying types of antioxidants. Following a good diet that has many different types of nutritional food may be the best way to ensure you get all of the antioxidants needed for a healthy lifestyle.
Vitamin A is an important immune system stimulant. Vitamin A deficiency may increase the risk of cancers of the lung, larynx, bladder, esophagus, stomach, colon, rectum and prostate. Vitamin A is stored in the liver and fat cells of the human body and can reach toxic levels.
Up to one-third of older people can no longer absorb Vitamin B from their food. Vitamin B is needed to form red blood cells and keep nerves healthy.
Vitamin E is also clinically proven as an effective antioxidant. It helps in supplying oxygen to the heart and other muscles of the body and aids in the functioning of the immune system.
