What theory of aging is demonstrated by a 74-year-old client incorporating more fresh fruit and vitamin supplements to increase antioxidant levels?

The free radical theory of aging posits that aging results from cumulative damage caused by free radicals, which are unstable molecules that can damage cellular components such as DNA, proteins, and lipids. By incorporating more fresh fruit and vitamin supplements, the client is actively seeking to increase antioxidant levels in their body. Antioxidants are known to neutralize free radicals, thereby potentially reducing oxidative stress and cellular damage, which can contribute to the aging process.

This proactive approach to health emphasizes the significance of dietary choices in combating the effects of aging, specifically by targeting the oxidative damage associated with free radicals. This demonstration perfectly aligns with the principles of the free radical theory and underscores the importance of nutrition in aging-related health strategies.
