Which of these nutrients can be classified as dietary antioxidants?

Vitamins are essential organic compounds that play a vital role in numerous bodily functions, including acting as dietary antioxidants. Specifically, certain vitamins, such as vitamin C and vitamin E, are well-known for their antioxidant properties. These vitamins help to neutralize free radicals—unstable molecules that can cause oxidative stress and damage to cells. By combating oxidative stress, dietary antioxidants contribute to the prevention of various diseases and promote overall health.

Proteins, minerals, and carbohydrates, while important for various physiological functions, do not primarily serve as antioxidants. For example, proteins are involved in building and repairing tissues, minerals contribute to enzyme functions and bone health, and carbohydrates primarily serve as a source of energy. However, they do not possess the characteristic of neutralizing free radicals like vitamins do. Hence, vitamins stand out as the primary dietary antioxidants in this context.
