Canadian Researchers Discover New Evidence That Vitamin D Shuts Down Cancer Cells

Use Natural Sunscreen

Skin color adapts to sunlight intensities which produce vitamin D or ultraviolet light damage to folic acid.

Researchers at the University of Leeds suggest that people with very pale skin may be unable to spend enough time in the sun to make the amount of vitamin D the body needs — while also avoiding sunburn.

The key is to stay away from conventional subscreen and use non-toxic alternatives to extend exposure time.

The further you live from the equator, the longer exposure you need to the sun in order to generate vitamin D. Canada, the UK and most U.S. states are far from the equator and the logic of using sunscreen is quickly becoming illogical even in scientific circles.

Unlike fads that sizzled and fizzled, the evidence for Vitamin D’s health benefits is now strong and keeps growing. If it bears out, it will challenge one of medicine’s most fundamental beliefs: that people need to coat themselves with sunscreen whenever they’re in the sun. Doing that may actually contribute to far more cancer deaths than it prevents, some researchers think.

The vitamin is D, nicknamed the “sunshine vitamin” because the skin makes it from ultraviolet rays. Sunscreen blocks its production, but dermatologists and health agencies have long preached that such lotions are needed to prevent skin cancer.

Now some scientists are questioning that advice. The reason is that vitamin D increasingly seems important for preventing and even treating many types of cancer. (1)

Comprehensive scientific reviews indicate that 83% of 785 sunscreen products offer inadequate protection from the sun, or contain ingredients with significant safety concerns.

Only 17% of the products on the market are both safe and effective, blocking both UVA and UVB radiation, remaining stable in sunlight, and containing few if any ingredients with significant known or suspected health hazards.

The assessment is based on a review of nearly 400 scientific studies, industry models of sunscreen efficacy, and toxicity and regulatory information housed in nearly 60 government, academic, and industry databases.

Many products lack UVA protection. Fully 12% of high SPF sunscreens (SPF of at least 30) protect only from sunburn (UVB radiation), and do not contain ingredients known to protect from UVA radiation, the sun rays linked to skin damage and aging, immune system problems, and potentially skin cancer. FDA does not require that sunscreens guard against UVA radiation.

Sunscreens break down in the sun. Paradoxically, many sunscreen ingredients break down in the sun, in a matter of minutes or hours, and then let UV radiation through to the skin. Our analyses show that 54% of products on the market contain ingredients that may be unstable alone or in combination, raising questions about whether these products last as long as the label says. FDA has not proposed requirements for sunscreen stability.
