Which nutrient helps to protect the body from oxidative damage?

The nutrient that is known to protect the body from oxidative damage is antioxidants. Antioxidants are compounds that inhibit the oxidation of other molecules in the body. Oxidation is a chemical reaction that can produce free radicals, leading to cellular damage. Free radicals are unstable molecules that can cause harm to cell structures, proteins, and DNA, contributing to various chronic diseases and aging.

Antioxidants neutralize these free radicals by donating an electron, thereby stabilizing them and preventing further damage. Common antioxidants include vitamins such as vitamin C and vitamin E, as well as minerals like selenium and phytochemicals found in a variety of fruits, vegetables, and whole grains.

In contrast, carbohydrates, proteins, and fats play essential roles in providing energy, building and repairing tissues, and supporting hormonal functions, but they do not have the same protective properties against oxidative stress as antioxidants do. Understanding the specific roles of different nutrients emphasizes the importance of a balanced diet rich in fruits and vegetables to ensure adequate intake of antioxidants for optimal health.
