Antioxidants: protecting the body from oxidative stress
Antioxidants are substances that help protect the body from oxidative stress. Oxidative stress is an imbalance between the production of free radicals and the functioning of the body's antioxidant system. Free radicals are molecules that have an unpaired electron and can damage cells and tissues in the body. Antioxidants help prevent this process by reducing the number of free radicals and protecting cells and tissues from their effects.
Antioxidants can be obtained from food or supplements. Some of the more well-known antioxidants include vitamins C and E, beta-carotene, selenium and zinc. They are found in many foods such as fruits, vegetables, nuts and green tea.
In addition, antioxidants can be used for cosmetic and medicinal purposes. They help reduce signs of skin aging, such as wrinkles and age spots, and can be used to treat diseases associated with oxidative stress, such as Alzheimer's disease, cancer and diabetes.
However, not all antioxidants are created equal. Some may have side effects or even increase the risk of developing certain diseases. Therefore, it is important to get antioxidants from a variety of foods and use supplements only when needed and under the guidance of a doctor.
Overall, antioxidants play an important role in maintaining the body's health and protecting against oxidative stress. Getting them from food is the safest and most effective way to use antioxidants, and using supplements should only be done after consulting with your doctor.
