Create a Diet and Supplement Regimen Right for You

4. Find a doctor who specializes in geriatrics or anti-aging. Barbara M. Morris, RPh, author of Boomers Can Really Put Old on Hold, recommends an anti-aging doctor. But according to Marc R. Blackman, MD, chief of the laboratory of clinical investigation of the National Center for Complementary and Alternative Medicine (part of the National Institutes of Health), a geriatrician would be more mainstream and recommend fewer unproven treatments. "Anti-aging is like saying anti-puberty or anti-pregnancy. This is a natural process," he says. Whatever his or her style, your new doctor may recommend yearly assessment of various biomarkers, including lipids, DHEA, estrogen, cortisol, thyroid, lung function, and micronutrient assays.

5. Cut saturated fat, up omega-3 fats. It's gospel by now: eat less or no red meat; lose the cake and ice cream; consume more complex carbs, such as whole grains, fruits, and vegetables; and get plenty of fatty fish. The healthy fats in salmon, mackerel, and sardines help keep oxygen free-radical molecules from damaging your cells.

6. Consider moderating your total food intake. Studies in rats show that a 30% calorie restriction means longer life (no, it doesn't just seem longer!). Blackman also cites studies in rhesus monkeys showing a gain in years from a reduction in food. Obviously, losing excess pounds means less strain on your system.

7. Be careful when tweaking your hormones. Morris swears by controversial human growth hormone -- for her. Blackman is no fan. "There have been big studies to determine the relationship between decreases in human growth hormone and thinner bones, more body fat, and mood swings. Giving growth hormone can build muscle, but it has not been shown that the muscle is any stronger." HGH has also been associated with water retention, carpal tunnel syndrome, high blood pressure, and blood-sugar fluctuations. "[HGH science] is not at a point where any responsible provider could recommend it," Blackman says. And what about the other substance -- a steroid called DHEA -- often recommended for aging? "Dramatically less evidence than HGH!" exclaims Blackman. As for estrogen and progesterone replacement, it's been in all the papers. The combo therapy may increase, rather than cut, the risk of cancer and heart disease. Many natural alternatives to these substances exist -- your own situation should dictate your decision, but always consult your doctor.

8. Supplement, supplement, supplement. Most of us suffer from "overconsumption malnutrition" -- too much of the wrong things, Morris says. She takes a fistful of vitamins and minerals each morning. Even the cautious American Medical Association recently endorsed taking a daily multivitamin. In addition to the effective antioxidant vitamin C, Morris says CoQ10, vitamin E, alpha lipoic acid (another antioxidant), and perhaps some of those "mental acuity" mixtures in the health-food store should be in your medicine cabinet. Again, your doctor can help you fashion a routine.
