According to a survey by the International Food Information Council, intermittent fasting was the most popular weight loss diet in 2018. Some have called it a fad whose adverse effects have not been sufficiently studied, and

Medical Tests to Avoid

When I first started looking into chiropractic, I read about one of their continuing medical education (CME) offerings. CME for physicians is intended to update their knowledge so they can treat patients more effectively.  This chiropractic CME course didn’t try to inform chiropractors about new knowledge from recent studies (there isn’t much new chiropractic research),

Should I Get a Second Booster?

In China, COVID-19 vaccination is required for everyone and sometimes force and coercion are used. In the United States, vaccines are never required. No one is forced to get vaccinated, although consequences have been imposed; for instance, the unvaccinated have been refused employment for certain jobs and not allowed to attend public schools. The CDC makes recommendations,

The Prince of Alternative Medicine

It’s common knowledge that Prince Charles is a persistent and outspoken champion of alternative medicine, but the full story has never been told until now. Edzard Ernst reveals all the shocking details in this unauthorized biography. The shocks come from Charles’ own words, which Ernst quotes extensively.  It is beyond ironic that Charles’ supporters were

Misconceptions about Vitamins

In 1747, one of the first controlled clinical trials in the history of medical science involved vitamin C, but the researcher had no idea what a vitamin was: vitamin C wasn’t discovered until 1912. Scurvy, a disease caused by vitamin C deficiency, was rampant in the British Royal Navy, disabling and killing more sailors than

I have long been skeptical of the diagnosis of multiple chemical sensitivity (MCS). Here’s what I wrote about it four years ago in an article in Skeptic magazine: An episode of ABC’s Nightline news show about Dr. Rea’s controversial diagnoses and treatments aired in 2009.

The World’s Most Deadly Animal

Animals can be hazardous to human health. When asked to name the most dangerous animal, many people will give the wrong answer. Sharks have captured the attention of the public, and other animals that kill people may come to mind, like black widow spiders, rabid dogs, and venomous snakes. And don’t forget the human animal:

The Science and Pseudoscience of Aging

Some animals (such as hydras and some jellyfish) can apparently live forever, but we humans are all going to die. Longevity is desirable, but aging—a slow process of deterioration—is not. Hearing declines (half of those older than seventy-five have disabling hearing loss), as does visual acuity (by age eighty, 70 percent of white Americans have
