On February 28, a record in the Journal of the American healing connection (Jama) likened vitamins A and beta carotene to death pills that can expedite your funeral date by as much as five percent. While this Jama study may scare consumers away from the vitamin aisle, Harvard healing School has issued a guide called "Vitamins and Minerals: What you Need to Know" to help take the danger and difficulty out of supplement shopping.
Meier J. Stampfer, Md, PhD, a professor of Epidemiology and food at the Harvard School of social Health, edited the report. Highlights of the guide included the following tips:
Vitamine
Make sure supplements are Usp verified
When shopping, pick supplements bearing the U.S. Pharmacopeia Dietary Supplement Verification schedule (Usp-Dsvp) mark. The Usp establishes social standards for good ability medicines, dietary supplements and related products used to vocalize condition and treat disease.
Don't pay for marketing fluff:
According to the Harvard report, it doesn't matter whether vitamin C is derived from organic rose hips or synthesized in large batches in a laboratory. Your body will use the resulting vitamin similarly.
Plus, if you're not allergic to wheat, rice or lactose you don't need to pay extra for allergen-free vitamins.
Watch out for healing risky interactions:
Inform your doctor and pharmacists of all of the supplements you take to ensure that there are no potentially risky interactions in the middle of your medicines and the vitamins.
Verify vitamin benefits:
Before you spend on a bottle of herbs or coenzyme Q10, make sure that rigorous, large scale studies validate the costs and effectiveness of the product.
Vitamins Proven to benefit the Skin
Now that you know how to shop for vitamins, how do you know which vitamins and minerals are surely useful to the skin? Dermatologist Karen E. Burke, Md, observes that at least three antioxidants; selenium, vitamin E and vitamin C, are proven to decrease the corollary of the sun on the skin and forestall supplementary skin damage.
Selenium supports skin elasticity
According to the American Academy of Dermatology, selenium preserves tissue elasticity, and slows down the aging and hardening of tissues caused by oxidation. Also, oral supplements of 50 to 200 micrograms of selenium can safe the skin from damaging rays of the sun.
Moreover, a record in the February edition of Cancer Causes and operate reaffirmed the antioxidant properties of selenium and its ability to reduce unavoidable incidences of cancer.
Vitamin E protects against skin damage
Like selenium, vitamin E also possesses cancer preventing properties. For example, a study released in Carcinogenesis demonstrated that vitamin E supplements could help safe against tumors caused by ultraviolet radiation exposure.
In the study, researchers provoked tumors in mice by exposing them to ultraviolet radiation. Investigators then gave the mice operate meals or meals containing 62.5 international units of vitamin E per kilogram of body weight. Compared to the mice fed chow without vitamin E supplementation, the food with vitamin E reduced the tumor count in the mice by 30%.
Vitamin C promotes salutary skin growth
Similar to vitamin E, vitamin C repairs free radicals and prevents them from turning into cancers and accelerating aging. Vitamin C is the most abundant antioxidant found naturally in the skin and it helps the skin generate collagen. The protein collage comprises much of the skin.
A few years ago, researchers from Duke University examined the corollary of vitamin C on the ability of skin cells to generate collagen. In this study, researchers used skin cells from two age groups- newborns aged eight to three days old and elderly persons aged in the middle of 78 to 93 years old. In the cells not treated with vitamin C, the younger cells spurred more collagen increase than the elderly cells did.
Yet, once researchers added vitamin C to both sets of skin cells, the cells produced collagen at a faster rate in both groups. This led the investigators to conclude that vitamin C could help counteract the general decline of collagen yield in aged skin.
While the newest nutritional gossip may have you emptying all your skin supplements in the toilet, you may still want to keep selenium and vitamins E and C around. food is not only about how you digest food, but how you act before, while and after you consume nutrients. May all your feedings, foods and supplements, fortify you.
