Jump to: — What are antioxidants? Another constant threat comes from chemicals called free radicals. In very high levels, they are capable of damaging cells and genetic material. The body generates free radicals as the inevitable byproducts of turning food into energy.

Antioxidants are natural or human-made substances that play a role in some cases of cell damage prevention or delay.

Read on to learn more. Antioxidants are molecules present in the body and found in plant-based foods that counteract oxidative stress.

Oxidative stress happens when there are more free radicals in the body but fewer antioxidants available to remove them. Free radicals are molecules or fragments of molecules with at least one set of unpaired electrons. They try to form bonds with atoms, electrons, or molecules to become stable.

As a result, free radicals can be a byproduct of normal metabolism. They may also form in response to exercise , sun exposure, and environmental pollutants like smog and cigarette smoke. The oxidative stress triggered by free radicals damages healthy cells and is thought to play a role in a variety of diseases, including:.

Antioxidants work to protect healthy cells from free radical attacks. By doing so, they help maintain proper physiological function and guard your health. There are two major types of antioxidants: endogenous and exogenous.

Endogenous antioxidants are ones that the body can produce. They can exist as enzymes, such as catalase CAT , or in non-enzyme forms like bilirubin or uric acid.

Antioxidants considered to be exogenous are ones that the body can't produce. These are the antioxidants most people may be familiar with, as they have to come from food.

Examples of exogenous antioxidants include:. Many plant-based foods provide antioxidants, so they're easy to come by. Some of the top sources include:.

To take in a broader spectrum of antioxidants—as well as vitamins, minerals, and fiber—aim for various plant-based food groups of different colors. Another way to increase your antioxidant intake is to replace processed foods with whole, plant-based foods.

Also, consider the following ideas and tips for increasing antioxidant consumption:. Antioxidant supplements are dietary supplements based on antioxidants that you can get from food like selenium, vitamin C, and beta-carotene.

Just like natural antioxidants, the supplements are intended to eliminate free radicals. However, scientists have concluded that getting antioxidants from foods is better than supplements.

Antioxidant supplements tend to come in high doses. Too much of any antioxidant can be more harmful than helpful. Also, research regarding the effectiveness of antioxidant supplements has been mixed, or the supplements have not resulted in significant benefits to individuals' health in the studies.

Some research has linked high-dose beta-carotene supplement use with an increased risk of lung cancer in smokers. Taking high-dose supplements of vitamin E has been associated with an increased risk of both hemorrhagic stroke—a type of stroke caused by bleeding in the brain—and prostate cancer.

Also, drug interactions can occur between antioxidant supplements and any medications you may be prescribed. As any glutathione in the gut is broken down to free cysteine, glycine and glutamic acid before being absorbed, even large oral intake has little effect on the concentration of glutathione in the body.

Measurement of polyphenol and carotenoid content in food is not a straightforward process, as antioxidants collectively are a diverse group of compounds with different reactivities to various reactive oxygen species.

In food science analyses in vitro, the oxygen radical absorbance capacity ORAC was once an industry standard for estimating antioxidant strength of whole foods, juices and food additives, mainly from the presence of polyphenols.

Alternative in vitro measurements of antioxidant content in foods — also based on the presence of polyphenols — include the Folin-Ciocalteu reagent , and the Trolox equivalent antioxidant capacity assay. Contents move to sidebar hide.
