The parade of diet fads is unending; they will continue to proliferate as long as humans have to eat. They have created a hellish world in which every food component is a potential demon: fat, gluten, carbs, sugar, wheat, salt, etc. Diet gurus, both professional and amateur, are always… read more "Food Faiths and Diet Religions"
Decoding Food Labels
It is only natural for food companies to present their products in the best light so people are more likely to buy them. If they can give the impression that their foods are healthy, low in calories, and low in added sugar, it’s to their advantage. But food labels can… read more "Decoding Food Labels"
Smokey the Bear Medicine and Prevention
When I was an intern, we used to joke that we were practicing “Smokey the Bear” medicine: stamping out forest fires. Patients would wait until a spark of disease had developed into a dangerous flame, and then they’d expect us to deal with it. We were mostly doing disaster control,… read more "Smokey the Bear Medicine and Prevention"
Colloidal Silver, Smurfs, and Ebola
Colloidal silver is back! It competed in the ring of science and was thoroughly clobbered. If it had any dignity, it would have stayed down for the count and admitted defeat; but like some bizarre whack-a-mole or zombie it keeps stumbling back to its feet, wanting to fight again. This… read more "Colloidal Silver, Smurfs, and Ebola"
Evidence: “It Worked for My Aunt Tillie” Is Not Enough
Evidence means different things to different people. Even quacks and their victims claim to have evidence that their treatments work. Sometimes that evidence consists only of testimonials from satisfied customers or from personal experience. “I tried X and I got better.” “I know Y works because it cured my Aunt… read more "Evidence: “It Worked for My Aunt Tillie” Is Not Enough"

Who’s Crazy Now? DSM-5 and the Classification of Mental Disorders
What does it mean to be crazy? We use the word loosely. In casual conversation we might say “He’s crazy” or “That’s insane!” but that doesn’t mean we really think the person is certifiable. Sometimes all it means is “He doesn’t agree with me.” What does it take to be… read more "Who’s Crazy Now? DSM-5 and the Classification of Mental Disorders"
Mirror Neurons and the Pitfalls of Brain Research
In his new book The Myth of Mirror Neurons: The Real Neuroscience of Communication and Cognition , Gregory Hickok, a professor of cognitive science, challenges current conceptions about mirror neurons. He shows how a complex mythology arose and why it is unwarranted, how experimental results were misinterpreted and disconfirming evidence ignored, and… read more "Mirror Neurons and the Pitfalls of Brain Research"
On Miracles
Is there such a thing as a miracle? Miracles are defined as unusual events that are not explicable by scientific or natural laws and that are assumed to be the result of supernatural intervention. The very concept is so fuzzy that it borders on the unintelligible. Religious believers refer to… read more "On Miracles "
Music Hath Charms But “Sound Healing” Hath Nonsense
There is no doubt that music has effects, both pleasant and unpleasant. We respond to music with emotion and with foot-tapping. As Congreve famously said, “Music hath charms to soothe a savage breast.” Cows produce more milk when music is played in the barn. Infants respond to lullabies. But music… read more "Music Hath Charms But “Sound Healing” Hath Nonsense"
