Natural Medicine, Starvation, and Murder: The Story of Linda Hazzard

History is replete with doctors who practiced quackery. Here is the story of one such quack whose fasting therapy resulted in many deaths, a story that is so bizarre and horrific that it's hard to believe it really happened, but it did.

Diet and exercise versus cancer: A science-based view

Yes, diet and exercise can be useful to prevent some cancers. Unfortunately, they don't prevent all cancers, and the effect size is more modest than often represented.

Vegan Betrayal: The Myths vs. the Realities of a Plants-Only Diet

NOTE: The original version of this book review was criticized for not making it clear when I was simply reporting the book’s content and when I was expressing support for one of its arguments. I have revised it to make it more clear. The additions are marked by brackets. Vegetarians come in several flavors. Ovo-vegetarians eat eggs, lacto-vegetarians eat dairy products but...

The rise and inevitable fall of Vitamin D

It’s been difficult to avoid the buzz about vitamin D over the past few years. While it has a  long history of use in the medical treatment of osteoporosis, a large number of observational studies have linked low vitamin D levels to a range of illnesses.

Supplements, Lies, and a Lengthy Transcript

S. 784, sponsored by Sen. Orrin Hatch, would eventually be enacted...
