Red Beet Essay
1. Antioxidant Compounds in Red Beet
Excessive formation of free radicals such as reactive oxygen species (ROS) and reactive nitrogen species (RNS) occur as a byproduct of cellular metabolism. Free radical generation causes oxidative stress which has been associated with undesirable health effects (Valko et al., 2007). Antioxidants are needed when ROS are generated inside the body, as the first line of defense (Lobo et al., 2010). Halliwell & Gutteridge (2015) describe an antioxidant as “any substance that delays, prevents or removes oxidative damage to target molecules” (Halliwell & Gutteridge, 2015). In a normal cell, there is an appropriate balance between the generation of free radicals and the amount of antioxidants present under normal physiological conditions. The human body can supply endogenous antioxidants that are generated by its own metabolic processes (). However, the amount of endogenous antioxidants available under the normal physiological conditions is sufficient only to deal with the normal threshold of a physiological rate of free radical production (). Therefore, exogenous antioxidants, obtained from a diet rich in fruits, vegetables, spices, herbs, cereals, legumes, and animal derived food are required when the normal threshold for free radicals is exceeded.

    Modern day society has put a massive emphasis into advertising antioxidants. Just about everyone has heard the word “antioxidant.” At least 150 million Americans regularly take dietary supplements that include antioxidants. Magazines, newspaper articles, product labels, supermarket displays, cosmetics, et cetera, hype the antioxidant potential, and market countless supplements as an additive to a healthy, youthful diet and lifestyle. “All seem to promise that eating the right antioxidant super food or , better yet, popping the right antioxidant pill will help ward off chronic disease, maybe even aging itself” (Antioxidant reality check, 2007, p. 1). Antioxidants are nutrients that help to lower the amounts of free radicals in your body by providing them with the oxygen molecule that they are missing and making them stable. Antioxidants are thought to block the damaging effects of free radicals of arterial walls as well as damage to cells that could cause cancer. So of course, one would be led to think, if you add more antioxidants to your diet then you could protect yourself from disease, slow the aging process, and be healthier overall. On the other hand, because there have only been observational studies and no long term medical research to prove the benefits of antioxidant supplementation, the benefits have not been completely accepted by the medical community.…

    Free Radicals and Aging

    • 445 Words
    • 2 Pages

    Free radicals are unstable oxygen molecules produced naturally in our body. When cells metabolize energy, these molecules are released. They interfere with normal cell function as their reaction to other cellular chemicals destroys fats, proteins and damaging DNA. Free radicals adversely alter proteins and lipids, triggering broad health issues. While cells are generally notorious for the rate at which they repair and regenerate, this rate is reduced dramatically as the skills of the cells can be hampered by the aging process itself or by the lack of adequate materials to initiate and promote healing. Put most simply, free radicals ultimately onset the unraveling of human DNA. If free radicals overwhelm the body’s abilities to regulate normal functions, the onset of a condition known as Oxidative Stress ensues. According to experts, over 60 age-related diseases (including cancer, cataracts, arthritis, neurodegenerative, and cardiovascular disease) have been proven to be closely associated with free radical cellular damage.…
