antioxidants are chemicals that prevent the harmful effects of oxidation in these cells in the body. Researchers have noted that the oxidative damage caused by free radicals is one of the main reasons behind the chronic and degenerative disorders. Antioxidants are mainly found in fruits and vegetables. Many health experts suggest that consumption of antioxidants as food offers more health benefits, which when taken in supplement form. While it is not possible to completely block free radicals, consuming foods rich in antioxidants help in reducing their presence inside the body.
Here are 5 benefits of antioxidants you should know about:
immune Benefits of antioxidants
University Penn state explains that the antioxidants present in food helps boost immune function by destroying free radicals, which are highly reactive compounds that are produced by normal body processes or enter the body through the environment. These antioxidants include selenium, polyphenols and vitamins A, C and E. Antioxidants play an integral role in preventing cancer and HIV infection by strengthening the immune system and the destruction of free radicals.
Anti-Aging benefits of antioxidants
the Mayer USDA Human Nutrition Research Center on aging at Jean tuffs University has participated in clinical trials over the past 8 years to determine the relationship between antioxidants and aging. These clinical studies have shown that diets rich in antioxidants may reduce age-related losses in cognitive performance and reduce inflammatory chemicals in the brain that could lead to deficiencies of behavior and nerve impairment in the elderly.
Antioxidants fight against cancer
While there are several conflicting views on antioxidants for cancer, a large number of research studies and laboratory animals have indicated that antioxidants can help prevent cellular damage caused by free radicals, linked to the cancer, according to the National Institute cancer. They also concluded that antioxidants may slow or even stop the development of cancer. However, clinical studies are continually examining the role of antioxidants in preventing cancer in humans. Antioxidants such as catechins present in tea, help in slowing the growth of tumors, and prevent colon and skin. Resveratrol, present in red grape skin, helps in preventing breast, lung, prostate and colorectal cancers.
benefits of antioxidants for eye health
research has shown that antioxidants such as vitamins C and E, zinc and carotenoids may protect the eyes from harmful blue light from the sun. According to a research study published in the journal Archives of Ophthalmology, low levels of antioxidants are linked to loss of vision and macular degeneration related to age in the elderly.
benefits of antioxidants for heart health
red wine, when consumed in moderation, can keep your heart healthy. This is because red wine is a good source of antioxidants, such as flavonoids and resveratrol. In addition, antioxidants help in the prevention of heart disease by improving HDL lipoprotein (high level) while lowering LDL (low density lipoprotein). Antioxidants may also prevent arterial damage. According to a research study published in the journal Nutrition Journal in 2008, the polyphenols present in green tea may help lower cholesterol, blood pressure, and markers of oxidative stress.
