They are derived from molecular oxygen under reducing conditions, such as when a person breathes. However, because of their high reactivity, free radicals often participate in unwanted side reactions resulting in cell damage. Many forms of cancer are thought to be the result of reactions between free radicals and DNA, resulting in mutations that can adversely affect the cell cycle and potentially lead to malignancy.
Free radicals are highly reactive chemical substances that are produced when the body undergoes the process of oxidation. The reason that free radicals are highly reactive is that they lack electrons, which cause them to be highly unstable. To achieve maximum stability, free radicals therefore steal electrons from other molecules around them and in so doing, destroy the cell membranes and weaken the cell.
"It's still too early to say definitely, but honey seems to have potential to serve as a dietary antioxidant," Engeseth said. In January, Engeseth and Jason McKibben, a researcher with Anheuser Busch in Santa Monica, CA, reported in the same journal that the dietary antioxidants in honey were more effective compared to traditional preservatives, such as butylated hydroxytoluene and tocopherol in slowing oxidation in cooked, refrigerated ground turkey.
With antioxidant supplements still far from the high expectations of the scientific community, you can in the meantime turn to the more reliable source of these helpful compounds, which are antioxidant foods. Below are some examples of antioxidant foods which you can include in your daily diet: Berries The provocative allure, the fragile charm, the rich concentration of nutrients.
It seemed that the more free radicals you have in your body, the faster the aging process becomes. Free radicals are harmful, unstable substances that develop after oxidation, a naturally occurring process of the body. Free radicals are not harmful in themselves. In fact, they can be beneficial. The only problem is they do not distinguish between healthy and harmful molecules so that there is a great possibility that they would also "attack" your other healthy cells, causing massive cellular damage, tissue damage, and eventually resulting in a chronic disease or disorder, such as aging.
During oxidation, certain chemical substances are produced and among them are those that are highly reactive and chemically unstable. These substances are called free radicals. Free radicals can be harmful to the body, especially if there is an excess of them. They may cause damage to the cell membranes, causing them to weaken.
