Antioxidants are naturally occurring compounds that play a crucial role in maintaining the body’s health by neutralizing free radicals—unstable molecules that can cause oxidative stress. Oxidative stress arises when there is an imbalance between free radicals and antioxidants in the body, leading to cellular damage. This damage can contribute to various chronic diseases and accelerate the aging process.
Antioxidants work by donating electrons to free radicals, effectively stabilizing them and preventing them from causing harm to cells. This protective mechanism is vital for maintaining cellular integrity and function, as well as for promoting overall health. The body produces some antioxidants endogenously, such as glutathione, but it also relies on dietary sources to obtain a wide range of these beneficial compounds.
Common antioxidants include vitamins C and E, beta-carotene, and selenium, among others. These substances can be found in a variety of foods, particularly fruits, vegetables, nuts, and whole grains. The synergistic effect of these antioxidants working together enhances their overall efficacy in combating oxidative stress.
Understanding how antioxidants function at a molecular level provides insight into their importance in health and disease prevention, highlighting the need for a balanced diet rich in these protective compounds.
