What are antioxidants and how do they work in the body?
Antioxidants are compounds that help protect the body from damage caused by harmful molecules called free radicals. Free radicals are unstable molecules that can cause damage to cells and DNA, leading to chronic diseases such as cancer, heart disease, and Alzheimer’s disease. Antioxidants work by neutralizing free radicals before they can cause damage.
The body naturally produces some antioxidants, but it also needs to obtain them from food sources. Common antioxidants include vitamins A, C, and E, as well as minerals like selenium and zinc. Other antioxidants come from plant-based compounds called phytochemicals.
Antioxidants can help protect the body from oxidative stress, which occurs when there is an imbalance between free radicals and antioxidants in the body. This can happen due to factors like pollution, smoking, and a poor diet. By reducing oxidative stress, antioxidants can help prevent chronic diseases and promote overall health.
It’s important to consume a variety of antioxidant-rich foods to ensure that the body gets all the nutrients it needs. In the next section, we’ll discuss the benefits of antioxidants in preventing chronic diseases.
