Antioxidants play a vital role in reducing the rate of specific oxidation reactions, which involve the transfer of electrons from a substance to an oxidizing agent. In the context of organic chemistry and biology, these chemical warriors are of utmost importance, as they protect living cells from oxidative damage, ensuring the integrity of their components. The significance and complexity of antioxidants in biology have led to an extensive body of medical literature, with over 142,000 scholarly articles dedicated to their study.
The inclusion of antioxidant-rich plant-based foods in our diet is essential for maintaining good health, as plants serve as a primary source of organic antioxidant compounds. Consequently, antioxidants have become a common ingredient in dietary supplements, touted for their potential in preventing cancer and heart disease. While numerous studies have suggested the benefits of antioxidant supplementation, large clinical trials have not consistently demonstrated clear advantages for the tested formulations, and in some cases, excessive supplementation could even be harmful.
Researchers have established a strong correlation between oxidative damage and the development of various diseases. For instance, oxidative damage to LDL (low-density lipoprotein) is associated with cardiovascular disease. This complex process involving multiple chemical pathways and networks begins with the oxidation of LDL by free radicals, leading to inflammation and the formation of plaques.
Studies suggest that consuming antioxidant-rich foods can reduce cellular and biochemical damage caused by free radicals. This, in turn, may slow down, prevent, or even reverse certain diseases resulting from cellular damage and possibly decelerate the natural aging process.
The importance of antioxidants in our diet has been recognized since the discovery of vitamins. In recent times, mounting evidence has shown that supplementing the diet with various types of antioxidants can improve health and potentially extend life.
In response to this growing interest, many nutraceutical and health food companies now offer antioxidant supplements in various forms. Some supplements contain specific antioxidant chemicals, such as resveratrol from grape seeds, while others combine antioxidants like beta carotene (provitamin A), vitamin C, vitamin E, and selenium in “ACES” products. Additionally, specialty herbs known for their antioxidant properties, like green tea and jiaogulan, are also available.
