An explanation of antioxidants as well as how they perform their functions is elucidated in this article. Antioxidants refer to substances that counteract the damage produced by oxygen, including that generated by free radicals. They are well-known compounds, namely enzymes and vitamins C, E, and beta-carotene, that can mitigate the detrimental effects of oxidation. They are also often added to food items, viz. vegetable oils and prepared meals, in order to prevent or postpone degradation caused by air. They are synthetic or natural agents that may help prevent or postpone some forms of cell damage. Numerous foods, including fruits and vegetables, contain antioxidants. Additionally, they are available as dietary supplements. Some plant-based foods are believed to be antioxidant-dense. Botanical antioxidants are classified as phytonutrients since they are obtained from plants. Additionally, the human body produces some antioxidants, which are referred to as endogenous antioxidants. Exogenous antioxidants come from somewhere outside the body and protect the body from damage. Antioxidants are considered to assist our human systems in neutralising free radicals, which is considered to improve general wellness.

Free radicals are metabolic waste products created by cells when they consume food and react to their surroundings. Oxidative stress can occur if the body is unable to adequately handle and eliminate free radicals. This can have a detrimental effect on cells and bodily functions. Additionally, free radicals are referred to as reactive oxygen species (ROS). Internal influences, for instance, inflammation, can boost the formation of free radicals in the body, as can environmental factors including pollutants, harmful UV rays, and tobacco smoke. These actions and exposures have the potential to cause cell impairment. This may result in an increased release of free iron or copper ions, activation of phagocytes, a kind of white blood cell involved in infection defence, increased enzymes that produce free radicals, and disturbance of electron transportation chains. All of these factors can contribute to oxidative stress. Oxidative stress has been related to cardiovascular disease, cancer, rheumatoid arthritis, stroke, respiratory illnesses, immunodeficiency, emphysema, Parkinson’s disease, and a variety of other inflammatory or ischemic problems. At times, the phrase “free-radical scavengers” is used as an explanation of antioxidants.


Antioxidants are estimated to be hundreds, if not thousands, of compounds. Each one has a specific purpose and can work together to help the body run smoothly. The word “antioxidant” refers to the impact that a range of substances can have. Exogenous antioxidants include vitamin A, vitamin C, vitamin E, beta-carotene, lycopene, lutein, selenium, manganese, and zeaxanthin. Plant foods include antioxidants and phytonutrients such flavonoids, flavones, catechins, polyphenols, and phytoestrogens. Antioxidants have distinct functions and cannot be replaced. That’s why a varied diet is vital. Fruits and vegetables contain antioxidants. They’re also called “superfoods” or “functional foods.” The following is an explanation of antioxidants found in foods: Yogurt contains vitamin A. Berry, orange, and bell peppers contain vitamin C. Nuts, seeds, oils, and leafy greens contain vitamin E. Beta-carotene is present in carrots, peas, spinach, and mangoes. Tobacco and melon contain lycopene. Leafy greens, maize, papaya, and oranges contain lutein. Selenium is a trace element found in whole grains such as rice and maize. Antioxidants are found in eggplants, beans (particularly kidney and black beans), red grapes, dark chocolate, pomegranates, and goji berries.

Antioxidants are considered to help mitigate various illnesses. According to one study, a basic explanation of antioxidants is they are chemical substances that shield cells from the damage caused by free radicals. Another study indicates that antioxidant supplementation may aid in the reduction of visual loss associated with age-related macular degeneration in older adults. Yet, there is a dearth of data to suggest that increasing particular antioxidant consumption might lower the risk of illness. Antioxidants are abundant in vegetables and fruits. Although research indicates that people who consume more vegetables and fruits have a lower risk of developing several diseases, it is unclear whether these findings are due to the antioxidant content of vegetables and fruits, other components of these foods, other factors in people’s diets, or other lifestyle choices. There is compelling evidence that eating a diet rich in vegetables and fruits is beneficial to one’s health. Organic fruits and vegetables outperform conventional food products by a wide margin.
