Antioxidants: What You Need to Know As the name implies, antioxidants are substances that are capable of counteracting the damaging, but normal, effects of the physiological process of oxidation in animal tissue.Antioxidants are nutrients (vitamins and minerals) as well as enzymes (proteins in your body that assist in chemical reactions).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.t is impossible for us to avoid damage by free radicals. Free radicals arise from sources both inside (endogenous) and outside (exogenous) our bodies. Oxidants that develop from processes within our bodies form as a result of normal aerobic respiration, metabolism, and inflammation.

Antioxidants Free radicals may play a role in heart disease, cancer and other diseases. Antioxidants, such as vitamins C and E, and carotenoids may help protect cells from damage caused by free radicals. Other naturally occurring antioxidants include flavonoids, tannins, phenols and lignans. Plant-based foods are the best sources.These include fruits, vegetables and their juices, whole-grain products, nuts, seeds, herbs and spices, and even chocolate. As a bonus, most foods high in antioxidants are high in fiber, low in saturated fat and cholesterol, and good sources of vitamins and minerals.ree radicals may play a role in heart disease, cancer and other diseases.

What Antioxidants Are and Why They Are Beneficial To Our Health Antioxidants benefit us by helping to protecting us against free radicals in our environment. Our immune system creates antioxidants which are able to neutralize free radicals and prevent much cellular damage. We can also consume antioxidants in our diet in fruits, vegetables, nuts, grains, some meat, poultry and fish.I bet you may recognize these antioxidants: vitamin E, C and beta carotene.learly antioxidants are important for all of us to strengthen and protect our immune systems and to help guard against disease. Antioxidants may even help us live longer.

Antioxidants Vitamins & Minerals: The most well-known antioxidants are: vitamins A, C, and E; beta carotene; the mineral selenium; and more recently lycopene, a carotenoid. Carotenoids are plant pigments-usually red, orange, or deep yellow-that provide the array of colors in fruits and vegetables.oods contain many different combinations or interactions of phytochemicals that supplements can't duplicate. Food sources of antioxidants, including fruits, vegetables, whole grains, nuts and seeds, are potentially active in reducing risk for disease and can benefit your overall health.

What Are Antioxidants? | Antioxidant benefits | Antioxidants Foods | Antioxidants In Tea. As free radicals (see below) have deficiency of electrons, compounds are needed which can neutralize free radicals by donating their own electrons to free radicals but they themselves do not become free radicals in the process. Pecans, walnuts, hazelnuts, ground nut or peanuts, sunflower seeds contain good amount of antioxidants. 2  Roasted peanuts are far richer in antioxidants than apples, beets and carrots and comparable to the antioxidant content of strawberries and blackberries.

- There are three primary types of antioxidants found in nature. These include phytochemicals, vitamins, and enzymes. Most of the most powerful antioxidants are found in plants. This is due to the fact that plants are exposed to UV light all throughout the day.hytochemicals are the antioxidants that are naturally used by plants to protect themselves against free radicals. Studies show that humans who eat sources of phytochemicals also benefit from the antioxidant properties of the plant.

Antioxidant An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction that can produce free radicals, leading to chain reactions that may damage cells. Antioxidants such as thiols or ascorbic acid terminate these chain reactions. The term antioxidant is mainly used for two different groups of substances: industrial chemicals which are added to products to prevent oxidation, and natural chemicals found in foods and body tissue which are said to have benef

Antioxidants: In Depth However, there is debate as to whether consuming large amounts of antioxidants in supplement form actually benefits health. There is also some concern that consuming antioxidant supplements in excessive doses may be harmful. Vegetables and fruits are healthy foods and rich sources of antioxidants. The beneficial health effects of a diet high in vegetables and fruits or other antioxidant-rich foods may actually be caused by other substances present in the same foods, other dietary factors, or other lifestyle choices rather than antioxidants.

Antioxidants: In Depth Antioxidants are man-made or natural substances that may prevent or delay some types of cell damage. Diets high in vegetables and fruits, which are good sources of antioxidants, have been found to be healthy; however, research has not shown antioxidant supplements to be beneficial in preventing diseases.

What are Free Radicals? Antioxidants, present in many foods, are molecules that prevent free radicals from harming healthy tissue. Radicals do play a key role in several biological processes. They play a part in the work of the white blood cells called phagocytes, which eat bacteria and other pathogens in the body.

Antioxidants and cancer risk: the good, the bad, and the unknown Antioxidants prevent a chemical process known as “oxidation,” which is a natural part of living and aging. Oxidation damages cells and can lead to the development of disease, including Alzheimer’s, heart disease, and cancer. Antioxidants are found in fruits, vegetables, nuts, beans, grain cereals, and other foods. Even dark chocolate is rich in antioxidants.

- Any compound that can donate electrons and counteract free radicals has antioxidant properties. Natural antioxidants are mainly found in fruits and vegetables, marine plants, and some seafood that eat marine plants.There are thousands of antioxidant compounds out there, but the most common dietary ones are vitamins A, C, and E, beta-carotene, and lycopene.Antioxidants can also be produced artificially and consumed in supplement form.alseIf the human body were a baseball game, antioxidants would be the first baseman. Antioxidants are one of the first lines of defense that the body employs to keep free radicals in check and prevent them from causing a domino effect of damage on other cells.

What is the role of antioxidants in the body? Antioxidants in certain foods -- green tea, olive oil, blueberries, salmon or sunflower seeds -- act like superhero nutrients in the body. They extinguish toxic oxygen molecules known as free radicals, the bad byproducts of cell renewal that are also produced by pollution and sun damage.he body has a complex system of natural antioxidants to fight free radicals. There are vitamin antioxidants including vitamin C, A and E as well as enzyme antioxidants. These two types of antioxidants work together mopping up free radical as they are produced. Sun exposure depletes naturally occuring antioxidants.

BioAstin Astaxanthin Antioxidants benefit the body by neutralizing and removing the free radicals from the bloodstream. There are a wide range of antioxidants found in nature, and because they are so varied, different antioxidants provide benefits to different parts of the body.ntioxidants come up frequently in discussions about good health and preventing diseases. These powerful substances, which mostly come from the fresh fruits and vegetables we eat, prohibit (and in some cases even prevent), the oxidation of other molecules in the body.
