Vitamins, herbs and other dietary supplements are sold as natural alternatives to pharmaceuticals and many people turn to them in an attempt to improve their health. Others seek supplements to lose weight or after hearing that they can help with serious medical conditions. These products are now used at least monthly by more than half of all Americans—and their production, marketing and sales have become a $23.7 billion industry, according to the Nutrition Business Journal.
What Are Dietary Supplements and How Are They Regulated?
98-year-old Bob Stewart, a retired podiatrist and senior Olympian, credits his use of supplements for his healthy aging. Writer Betsy McMillan, a mother of two now adult children, however, nearly suffered permanent liver damage due to a supplement that contained potentially fatal levels of niacin.
Unlike pharmaceuticals—which must be FDA-approved as safe and effective before they can be marketed—supplements are considered as foods by regulators and assumed to be safe until proven otherwise. Although pharmaceutical manufacturers face inspections to ensure that the right dose is in the right pill without dangerous contaminants, supplements do not undergo such intense government scrutiny.

“According to that study, nearly half of the 500 most popular sunscreens may actually increase the speed at which malignant cells develop and spread skin cancer such as melanoma.
Why? Because they contain Vitamin A, an ingredient that was added to sunscreen formulations because it’s an antioxidant that slows skin aging.
This isn’t necessarily new information….as some studies suggest “that vitamin A might have some phototoxicity.”

Take it easy folks. One study on the effects of Vitamin A on skin cancers in animals does not invalidate sunscreen use. We don’t really need Vitamin A in sunscreens though. We need good blockers of UVA and UVB at an SPF of at least 30.

At home the kids’ current TV show of choice is How I Met Your Mother, supplanting Scrubs as the veg out show in the evening. Both shows are always on a cable channel somewhere and are often broadcast late at night. Late night commercials can be curious, and as I work on projects, I watch the shows and commercials out of the corner of my eye.
Law firms trolling for business seem common. If you or a family member has had a serious stroke, heart attack or death from Avandia, call now. The non-serious deaths? I suppose do not bother. One ad in particular caught my eye: anyone who developed ulcerative colitis or Crohn’s disease (collectively referred to inflammatory bowel disease, or IBD) after using Accutane, call now. Millions have been awarded.
My eye may have been caught because of my new progressive lenses, but I will admit to an interest in inflammatory bowel disease, having had ulcerative colitis for years until I took the steel cure. It also piqued my interest as these were three conditions among which I could not seen any connections. Accutane, ulcerative colitis, and Crohn’s. One of these is not like the other. Read more »

This week I’ve been trying to eat according to the DASH guidelines for lowering blood pressure. It actually hasn’t been too difficult — partly because I’m not following their strictest guidelines, which call for just 1,300 milligrams of sodium and 16 grams of saturated fat a day. I’ve been shooting for 2,300 milligrams of sodium and 22 grams of saturated fat.
In 2003, I tried a somewhat different “diet,” which in some ways was more difficult to follow, even though it only lasted one day. My son Jim (then age 11) and I ate every meal at McDonald’s for an entire day (yes, this was before Super Size Me). We recorded the experience on the Web. I thought it would be interesting to compare my day at McDonald’s to a typical day on DASH. Read more »

Many over-the-counter (OTC) cosmetic products contain retinoids and are promoted (advertised) as anti-aging products.
An article in the February 2010 issue of the Aesthetic Surgery Journal is a review of the evidence behind retinoids in cosmeceutical products. It turns out there isn’t much. Read more »
