Oxidation reactions that occur in the body can produce free radicals. This is very dangerous because it can cause chain reactions that can damage body cells. To prevent the danger of oxidation, antioxidants are needed. Antioxidants are substances that function to reduce damage to body cells due to oxidation. Excessive free radicals in the body are often associated with various diseases that attack the body. What Is Dangerous Oxidation Like? Every day, your body constantly interacts with oxygen. This process triggers the appearance of free radicals and can cause oxidative stress. Oxidative stress occurs when the amount of free radicals and the body's defenses (antioxidants) is out of balance and tends to be more free radicals. Free radicals are molecules that are very reactive in interacting with other molecules in the cell body. Free radical activity can cause damage to cell membranes, various proteins and genes. The damage caused is called oxidative damage. If this damage o
