Antioxidants include the Vitamins A,C and E, and yellow-coloured carotenoids, such as beta-carotene. There are a number of naturally occurring substances in food, such as vitamins and phenolic compounds which are large molecules comprised of a number of ring structures which have antioxidant properties.
Much research has recently focused on how antioxidant vitamins may reduce cardiovascular disease risk. Considerable laboratory evidence from chemical, cell culture, and animal studies indicates that antioxidants may slow or possibly prevent the development of cancer.
In order to understand antioxidants and cancer prevention, we must know what exactly antioxidants are and how they help our bodies.
The way in which Free Radicals are normally kept in check is by the action of Free Radical Scavengers that occur naturally in the body. Free radicals are cells that have lost an electron, thus are unstable cells. Antioxidants are substances that may protect cells from the damage caused by unstable molecules known as free radicals.
Antioxidants are abundant in fruits and vegetables, as well as in other foods including nuts, grains and some meats, poultry and fish. Although there are several enzyme systems within the body that scavenge free radicals, the principle micronutrient (vitamin) antioxidants are vitamin E, beta-carotene, and vitamin C. Not only does your body produce them as part of normal metabolism but there are also many external sources such as air pollution, alcohol, pesticides, sunlight, tobacco smoke, drugs, and even fried foods.
Only well-designed long-term research can determine whether any of these chemicals, taken in a pill, would be useful for preventing any disease.
When our body cells use oxygen, they naturally produce free radicals (by-products) which can cause damage. Antioxidants are often described as "mopping up" free radicals, meaning they neutralize the electrical charge and prevent the free radical from taking electrons from other molecules. They are believed to play a role in preventing the development of such chronic diseases as cancer, heart disease, stroke, Alzheimer's disease, Rheumatoid arthritis, and cataracts. Antioxidants boost our immunity, make our muscles stronger, and keep our bones and skin healthy. Antioxidants along with a good multi-vitamin are necessary as due to many busy lifestyles and careers, many of us are not getting all of our daily nutrients.
Under conditions of stress the human body's ability to produce antioxidants can become severely impaired.
Flavonoids are antioxidants found in plant pigments, fruits, vegetables, dark chocolate and certain beverages, such as Perugina Bittersweet, Dark Chocolate, and Dark Chocolate with nuts Bars. The more colorful fruits and vegetables, such as the deep orange, yellow, green, red and purple varieties, tend to be the richest sources of antioxidants.
There is still some question as to whether antioxidants in the form of dietary supplements counteract the effects of increased numbers of free radicals in the body.
The antioxidants in green tea have powerful anti-carcinogenic, cardio-protective, nuero-protective, and anti-microbial actions.
Oxygen damage (oxidation) to your cells may be partly responsible for the effects of aging and certain diseases. Researchers are studying how antioxidants in food may protect against this damage.
All living organisms maintain a reducing environment inside their cells, all cells contain complex systems of antioxidants to prevent chemical damage to the cells' components by oxidation. A diet containing polyphenol antioxidants from plants is required for the health of most mammals, since plants are an important source of organic antioxidant chemicals.
Many studies have suggested benefits for antioxidant supplements in laboratory experiments. At the molecular and cellular levels, antioxidants serve to deactivate certain particles called free radicals. Antioxidants are believed to slow down the formation of free radicals.
Although regular exercise produces many positive health benefits, it also causes an increased production of free radicals.
According to recent studies, antioxidant vitamins in produce and other foods may actually represent a modern-day "Fountain of Youth." The American Heart Association continues to promote a diet rich in fruits, vegetables, whole grains, fish, legumes, poultry and lean meats to derive antioxidant vitamin benefits.
Researchers also studied the effects of the antioxidant on mice. They found most notably that mice given a high-calorie diet and resveratrol had healthy livers, unlike the livers of mice given a high-calorie diet and no antioxidant.
Some scientific evidence suggests that consumption of antioxidant
vitamins may reduce the risk of certain forms of cancer.
However, FDA has determined that this evidence is limited and not conclusive.
Antioxidants can decrease LDL and cholesterol, increase high density lipoprotein(HDL), and lower blood pressure. An adequate and well-balanced supplementation of antioxidant nutrients, at doses that might be reached with a healthy diet that includes a high consumption of fruits and vegetables, had protective effects against cancer in men.
Recent research supports a specific role as an antioxidant in mitochondria, which have an high level of reactive oxygen species produced during aerobic metabolism, but lack some of the protective mechanisms of cell nuclei.
It is best to remember that vitamin and mineral supplements should never be used as substitutes for a healthy, well balanced diet!
