The Sunscreen Myth: How Sunscreen Products Actually Promote Cancer

Seven Important Questions About Sunscreen

The next time you see some public service advertisement urging you to smother yourself and your children with sunscreen chemicals, think hard before taking action. Ask yourself these seven commonsense questions:

1) Is the sun really dangerous to humans? If so, how did humans survive for the last 350,000 years on planet Earth?

2) Have the chemicals used in sunscreen products ever been safety tested or approved by the FDA? (The answer is no.)

3) Who financially benefits when you keep buying and using sunscreen products?

4) What is the environmental impact of sunscreen chemicals washing off into the ocean, a lake, a swimming pool or being washed down the drain in your shower?

5) Sunscreen manufacturers say the skin doesn’t absorb their chemicals. If that’s true, then how do nicotine patches work? How do transdermal drugs get absorbed through the skin if sunscreen chemicals don’t? (Answer: ALL these chemicals get absorbed through the skin. The skin is not selective about what it chooses to absorb.)

6) If the sun is so dangerous, then why is the vitamin generated by sunlight (vitamin D) so healthy for humans? Why would humans evolve a mechanism for generating a vitamin from sunlight if we weren’t supposed to be exposed to sunlight in the first place?

7) If sunlight is so dangerous, then why is virtually every living creature on planet Earth dependent on sunlight for survival? Plants use sunlight to generate their nutrition, too, and most animals eat either plants or other animals that originally ate plants. Nearly all life on planet Earth is powered by sunlight. Why does the cancer industry believe sunlight causes death when, in reality, sunlight delivers life?

Once you answer these questions, the reality of the situation becomes obvious: Sunlight is good for you, and sunscreen is a hoax.

The idea that sunscreen prevents cancer is a myth. It’s a myth promoted by a profit-seeking tag-team effort between the cancer industry and the sunscreen industry. The sunscreen industry makes money by selling lotion products that actually contain cancer-causing chemicals. It then donates a portion of that money to the cancer industry through non-profit groups like the American Cancer Society which, in turn, run heart-breaking public service ads urging people to use sunscreen to “prevent cancer.”

The scientific evidence, however, shows quite clearly that sunscreen actually promotes cancer by blocking the body’s absorption of ultraviolet radiation, which produces vitamin D in the skin. Vitamin D, as recent studies have shown, prevents up to 77 of ALL cancers in women (breast cancer, colon cancer, cervical cancer, lung cancer, brain tumors, multiple myeloma… you name it). Meanwhile, the toxic chemical ingredients used in most sunscreen products are actually carcinogenic and have never been safety tested or safety approved by the FDA. They get absorbed right through the skin (a porous organ that absorbs most substances it comes into contact with) and enter the bloodstream.

Vitamin D Deficiency Widespread During Pregnancy

Posted by Tan Man on March 2, 2008

“This study is among the largest to examine these questions in this at-risk population,” Marjorie L. McCullough, Sc.D., senior epidemiologist at the American Cancer Society, wrote in an accompanying editorial. “By the end of pregnancy, 90 percent of all women were taking prenatal vitamins and yet deficiency was still common.”

PITTSBURGH, February 27, 2007 — Even regular use of prenatal multivitamin supplements is not adequate to prevent vitamin D insufficiency, University of Pittsburgh researchers report in the current issue of the Journal of Nutrition, the publication of the American Society for Nutrition. A condition linked to rickets and other musculoskeletal and health complications, vitamin D insufficiency was found to be widespread among women during pregnancy, particularly in the northern latitudes.

“In our study, more than 80 percent of African-American women and nearly half of white women tested at delivery had levels of vitamin D that were too low, even though more than 90 percent of them used prenatal vitamins during pregnancy,” said Lisa Bodnar, Ph.D., M.P.H., R.D., assistant professor of epidemiology at the University of Pittsburgh Graduate School of Public Health (GSPH) and lead author of the study. “The numbers also were striking for their newborns – 92.4 percent of African-American babies and 66.1 percent of white infants were found to have insufficient vitamin D at birth.”

A vitamin closely associated with bone health, vitamin D deficiency early in life is associated with rickets – a disorder characterized by soft bones and thought to have been eradicated in the United States more than 50 years ago – as well as increased risk for type 1 diabetes, asthma and schizophrenia.

“A newborn’s vitamin D stores are completely reliant on vitamin D from the mother,” observed Dr. Bodnar, who also is an assistant investigator at the university-affiliated Magee-Womens Research Institute (MWRI). “Not surprisingly, poor maternal vitamin D status during pregnancy is a major risk factor for infant rickets, which again is becoming a major health problem.”

Lack of milk, sunshine and exercise hurts kids’ bones

Posted by Tan Man on March 2, 2008

 

U.S. children break their arms more

often today than four decades ago —

girls 56 percent more,

and boys 32 percent more,

according to a Mayo Clinic study.

 

 

Too little milk, sunshine and exercise: It’s an anti-bone trifecta. And for some kids, shockingly, it’s leading to rickets, the soft-bone scourge of the 19th century.

But cases of full-blown rickets are just the red flag: Bone specialists say possibly millions of seemingly healthy children aren’t building as much strong bone as they should — a gap that might leave them more vulnerable to bone-cracking osteoporosis later in life than their grandparents are.

“This potentially is a time-bomb,” says Dr. Laura Tosi, bone health chief at Children’s National Medical Center in Washington.

Now scientists are taking the first steps to track kids’ bone quality and learn just how big a problem the anti-bone trio is causing, thanks to new research that finally shows just what “normal” bone density is for children of different ages.

Dr. Heidi Kalkwarf of the Cincinnati Children’s Hospital led a national study that gave bone scans to 1,500 healthy children ages 6 to 17 to see how bone mass is accumulated. The result, published last summer: The first bone-growth guide, just like height-and-weight charts, for pediatricians treating children at high risk of bone problems.

Next, the government-funded study is tracking those 1,500 children for seven more years, to see how their bones turn out. Say a 7-year-old is in the 50th percentile for bone growth. Does she tend to stay at that level by age 14, or catch up to kids with denser bones? If not, is she more prone to fractures?

Ultimately, the question is what level is cause for concern.
