Everyone is talking about antioxidants, but misconceptions abound. For example, I just received an email that described antioxidants as “the ability to soak up toxins in the body.” One dictionary definition of an antioxidant is (1) “a substance that inhibits oxidation, especially one used to counteract the deterioration of stored… read more "Antioxidants: The Hype and the Reality"
Understanding Gluten
Until a few years ago, few people had even heard of gluten. Now going on a gluten-free diet has become a popular fad. People who have been diagnosed with celiac disease must avoid gluten to prevent symptoms; but others are avoiding gluten for questionable reasons, or for no reason at… read more "Understanding Gluten"
Is Meat Poison? Is Fat the Antidote?
Is a diet comprised solely of meat good for you? I think you know the answer. I have been watching the National Geographic series of documentaries Life Below Zero, which features individuals who live (often alone) in harsh conditions in the Alaskan wilderness. They are self-sufficient, providing their own water, heat,… read more "Is Meat Poison? Is Fat the Antidote?"
GOLO for Weight Loss
There are lots of testimonials from people who say they lost weight with GOLO, but its effectiveness is not supported by any scientific evidence. Advertisements for GOLO seem to be everywhere.

Misconceptions about Vitamins

The World’s First Productivity Drink
Magic Mind claims to be the world’s first productivity drink. It seems to me an increase in productivity should be easy to prove. If your widget factory produces 1,000 widgets a day you could do a controlled study comparing workers who used Magic Mind to workers who used a placebo. If… read more "The World’s First Productivity Drink"
The Word “Organic” Has Been Hijacked
The word “organic” has a precise definition in chemistry. It has been hijacked to refer to organic farming. Good communication requires that both parties use the same definition. Words matter. Imagine someone who only speaks English trying to communicate with someone who only speaks Mandarin Chinese. Imagine a physicist trying… read more "The Word “Organic” Has Been Hijacked"

Dietary Supplements and Deception
At least half of Americans (maybe as many as 2/3) take dietary supplements. They assume the government will guarantee safety, efficacy, and truthful advertising. They couldn’t be more wrong. The very term dietary supplement is based on a fiction. Dietary supplements are regulated by the FDA but the regulations are… read more "Dietary Supplements and Deception"
