Healthy aging tip #13: Choose fish for your skin.
Omega-3 fatty acids in oily fish or supplements can help control inflammation and improve skin conditions, according to Julia Hunter, M.D., a dermatologist in Beverly Hills, Calif.

"In your skin, inflammation breaks down collagen, enlarges pores and contributes to rosacea, psoriasis, eczema and aging," she says.

For women past childbearing age, the benefits of eating at least two servings of fish per week outweigh the potential risks of mercury contamination, according to the American Heart Association. But to be on the safe side, you may want to avoid species that tend to contain high levels of mercury, including swordfish, king mackerel or tilefish.

Fish-oil supplements may also be helpful, but ask your doctor before taking them, the AHA recommends.

Healthy aging tip #14: Discuss hormone therapy with your doctor.
Many post-50 women are leery of menopausal hormone therapy (MHT), a combination of progesterone and estrogen delivered in pills or a patch, especially after the Women's Health Initiative. That observational study found higher short-term heart disease risks for post-menopausal women on hormone therapy.

Still, for menopause symptoms, such as hot flashes, night sweats and vaginal dryness, it's the treatment with the strongest evidence behind it, says Allison Hill, M.D., a Los Angeles ob-gyn.

For some women, MHT may be an option to relieve menopause misery, especially if used at the lowest effective dose for less than five years, Dr. Hill says.

Don't take it if you have a "history of blood clots, strokes, heart attacks or breast cancer," she adds. (Certain breast cancers are fueled by estrogen.)

If you're bothered by moderate to severe menopausal symptoms, discuss the pros and cons of MHT with your doctor.
