The Dangers of Commercial Sunscreens, Part 2

Sunscreen

In last week’s post, I talked about the toxicity of commercial sunscreens, and why they are bad for your health. I also mentioned that the sun is not the primary cause of skin aging and skin cancer, and promised to share my conclusions with you this week.

Despite the enormously bad press the sun has received in the past few decades, all skin damage is not the fault of the sun. The root cause of skin aging (including wrinkling, hyperpigmentation, and loss of collagen) as well as skin cancer is oxidative damage caused by reactive oxygen species (ROS). While the sun is one of the factors that create ROS, there are many other culprits, including external factors (air pollution and chemical exposure) and internal factors (poor diet, emotional stress, lack of sleep, and the natural aging process). ROS are believed to trigger skin cancer and photosensitivity diseases by activating proliferative and cell survival signaling that can alter apoptotic pathways (the self-destruction of abnormal cells).

The Dangers of Commercial Sunscreens

Dangers of Sunscreen

Wherever I go this summer, it seems that people are slathering or spraying sunscreen onto themselves and their children. Whether or not you want to use sunscreen, you essentially have no choice – aerosol sprays disperse and pollute the air, and sunscreens and sun blocks wash off in pools or lakes, contaminating the water. (Despite what labels proclaim, there is no such thing as “waterproof sunscreen.”)

Are Fish Oils Harmful To Your Health?

You may have seen last week’s highly publicized study targeting fish and fish oil as a cause of increased prostate cancer. Published in the online edition of the Journal of the National Cancer Institute, the authors state that EPA, DPA and DHA (the fatty acids derived from fatty fish and fish-oil supplements) are associated with a 71 percent increased risk of high-grade prostate cancer, a 44 percent increase in the risk of low-grade prostate cancer, and an overall 43 percent increase in risk for all prostate cancers. These figures are enough to scare any man away from eating even one more salmon dinner.

Is Milk A Healthful Food?

Few dietary topics create as much controversy as the issue of milk. Billboards, commercials, and magazine ads (featuring celebrities with milk moustaches) encourage us to drink more milk via the influential “Got Milk?” campaign, launched by the dairy industry in 1993. Even our government promotes the heavy consumption of milk—the latest federal nutritional guidelines recommend the equivalent of 3 glasses of milk daily, either fat-free or 1% fat.

Unfortunately, the recommendations for dairy are channeled to us through the perspective of the dairy industry, and are based more on marketing schemes than on scientific research. If you didn’t already know, the dairy lobby is a powerful force, and drives the government’s recommendations.

Recent Highlights In Health Research

Painted Hills - health research

To enhance my work as a clinician, I spend an average of two hours every day researching and compiling data in the fields of health, nutrition, botanical medicine, dietary supplements, and conventional medicine. This includes evaluating studies on innovative pharmaceutical drug therapies, particularly in the realm of oncology.

From time to time, I’ll be sharing a few of the week’s highlights with you. I hope you will find these interesting, and perhaps the information will be beneficial for you or someone you know.

Evaluating New Guidelines for PSA Screening

Today’s guest article is written by Mark Bricca, ND, LAc. Mark practices as a clinician at the Mederi Centre for Healing in Ashland, Oregon.

For years, “routine” PSA screening was considered a standard part of prudent, preventive medicine, and surveillance was commonly encouraged by doctors for men beginning in their 50’s. About a year ago, in May of 2012, the U.S. Preventive Services Task Force (USPSTF) came out with a new recommendation—namely that all men, regardless of their age, should not regularly have PSA screening tests performed unless they are determined to be at increased risk for prostate cancer. What changed, and why the new guidelines? Let’s see if we can understand this whole situation a little better!
