antioxidant benefits and claims labels cover all grocery stores, but how they work and where they are naturally? Antioxidants consist of some vitamins, minerals, carotenoids and polyphenols found in a variety of foods. Vitamin C, vitamin E, beta carotene, carotenoids, some phytonutrients containing enzymes and some trace minerals (zinc, selenium, copper and manganese) are considered all antioxidants. They are associated with delay or prevent oxidative stress and repair damage to cells. Moreover there is some evidence that they can improve immune function and reduce the risk of cancer or infections.

Oxygen is constantly required by all cells of the body for energy. The hydrogen burns by producing cells byproducts called free radicals. Free radicals are molecules that lack an electron, which makes unstable and potentially damaging to DNA, body tissues and cells. To become stable, free radicals steal electrons from cells in the body, which can result in cell dysfunction and health problems such as heart disease, cataracts, diabetes, cancer, Alzheimer's disease, age-related deterioration and other issues health related. Free radicals can also be formed from negative environmental factors, such as UV light and cigarette smoke. You can see this reaction even in foods such as an apple and slices turn brown is cut due to oxidation - but when dipped in lemon juice, which goes blank

Antioxidants work by free radicals give an electron and thus conversion into waste products which can be eliminated from the body without harm. Antioxidants may even repair some of the damage already done. All work together synergistically different antioxidants, so a deficiency in one may hinder the effectiveness of the other. Some of the best known are vitamin C, vitamin E and carotenoids / beta carotene, which are precursors of vitamin A.

Vitamin C

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that helps form the connective tissue that holds the bones, muscles and tissues together and makes the capillaries and blood vessels strong. It also functions to allow your body to better absorb plant sources of iron and folic acid for the body to use.

As with all vitamins, minerals and phytonutrients, food sources are the best for your body. Be careful not on supplements, as research has not proven effective and in some cases there may be harmful side effects. Vitamin C rich foods include peppers, guava, papaya, oranges, broccoli, grapefruit, mango, melon, cabbage and kale. Citrus and fruit and vegetables are good sources.

Vitamin E

Vitamin E is an antioxidant that does more to fight the effects of oxidation and damage from free radicals! This fat-soluble vitamin may help reduce the risk of heart disease, stroke and other health problems. Helps protect vitamin A, essential fatty acids and LDL cholesterol is oxidized. The natural form of vitamin E is found in vegetable oils, nuts and sunflower seeds, soy, spinach and peanut butter is better than synthetic forms found in supplements absorbed. When cooking with vegetable oils, be careful not to overheat the oil or vitamin E is destroyed. Vitamin E protects the unsaturated fats in oils, nuts and seeds are oxidized.

Carotenoids, beta carotene and vitamin A

Beta carotene is one of the more than 600 different carotenoids, which are all precursors of vitamin A. Al as with other antioxidants, carotenoids provide protection against disease and degenerative changes associated with aging. They help maintain normal vision and ability to see in the dark, and maintain healthy skin and tissue infections. By supporting your immune system, these antioxidants can help reduce the risk of cancer and to promote growth and well-being of body tissues and cells. They are considered essential in the development of the embryo and reproductive cells. Vitamin A is a fat-soluble vitamin, which can have many adverse reactions if excessively supplemented. Dietary sources are well because your body slows down conversion of carotenoids into vitamin A once the body has stored enough.
