A client age 71 years has recently integrated large amounts of blueberry and pomegranate juice into her diet, touting their antioxidant properties that mitigate the effects of separated high-energy electrons
The client's actions reflect which of the following theories of aging?
A) Free radical theory
B) Genetic theory
C) Cross-linkage theory
D) Immunity theory
Ans: A
Free radicals, formed during cellular metabolism, are molecules with separated high-energy electrons, which can have adverse effects on adjacent molecules. Antioxidants are purported to mitigate the effects of these free radicals. Neither the genetic theory, immunity theory, nor cross-linkage theory of aging directly addresses the potentially harmful effects of free radicals.
