Natural approaches to anti-aging must take into account the modern theories of aging. There has been a tendency to look for “magic bullets,” but the causes of tissue aging are multi-factorial and the approach to anti-aging must be multi-pronged. Dietary supplements and natural topical agents have become extremely popular in the U.S., but their use is often questioned by conventional medicine. An appropriate argument has emerged that “anti-aging tactics” must be evidence-based .
In brief, widely accepted theories of aging include oxidative stress, cross-linking of body proteins, altered immunity, changes in genetic codes, stress theories and repair- budget theories. Of all theories of aging, most attention has focused on the free-radical theory of aging where the use of antioxidants appears to be of great potential.
