How do antioxidants contribute to health?

Antioxidants contribute to health primarily by reducing oxidative stress in the body, which is achieved through their ability to neutralize free radicals. Free radicals are unstable molecules that can cause damage to cells, proteins, and DNA through oxidative reactions. This damage is associated with various health issues, including chronic diseases such as cancer, heart disease, and neurodegenerative disorders.

By neutralizing these free radicals, antioxidants help to maintain cellular integrity and promote overall bodily health. They achieve this through various mechanisms, such as donating electrons to free radicals, which stabilizes them and prevents further cellular damage. This process is crucial not only for protecting against specific diseases, but also for supporting general health and longevity.

In contrast, the other choices do not accurately describe the primary role of antioxidants. While muscle growth and strength, digestion, and energy levels are important aspects of health, they are not directly influenced by the antioxidant properties that help combat oxidative stress. Thus, the function of antioxidants centers on their protective role against oxidative damage, making the second choice the correct answer.
