(NaturalNews) Brazilian supermodel Gisele Bundchen recently made the bold move of publicly denouncing conventional sunscreens. According to a report in theBundchen called the toxic lotions "poison," and said that she never puts any synthetic chemicals on her body."I cannot put this poison on my skin," the 30-year-old is quoted as saying while promoting her own natural line of body products. "I do not use anything synthetic."Bundchen's comments naturally sparked the wrath of many so-called experts who quickly defended sunscreen as a necessary intervention to prevent skin cancer. Head of dermatology at Brazil's National Cancer Institute, for instance, immediately began making bizarre allegations that sunscreen is of "fundamental importance" for preventing cancer, even though no evidence exists to back such claims.A 2008 study released by the U.S. Centers for Disease Control and Prevention (CDC) found that roughly 97 percent of Americans are contaminated with oxybenzone, a toxic sunscreen additive that is linked to allergies, hormone disruption, cell damage, and low birth weights ( https://www.naturalnews.com/022990_oxybenzone... ). And according to Philippe Autier, a scientists at the International Agency for Research on Cancer, sunscreens actually cause skin cancer rather than prevent it ( https://www.naturalnews.com/029110_sunscreen_... )."Sunscreens were never developed to prevent skin cancer," Zoe Diana Draelos, editor of thesaid in a 2010 report. "In fact, there is no evidence to recommend that sunscreens prevent skin cancer in humans."Besides containing a slew of toxic chemicals, sunscreens also block out the necessary ultraviolet (UV) rays that the skin needs to produce vitamin D. Limited sun exposure combined with the heavy use of toxic sunscreens is responsible for widespread vitamin D deficiency and its related diseases ( https://www.naturalnews.com/vitamin_d.html ).To learn more about the importance of vitamin D, visit:
