Red meat consumption has been linked to diabetes, cardiovascular disease, and several types of cancer (breast, colorectal, stomach, bladder, prostate, and lymphoma).
There are plausible mechanisms: Meat is a source of carcinogens, iron that may increase oxidative damage, and saturated fat. But correlation and plausibility are not enough to establish causation.
Is red meat really dangerous? If so, how great is the risk? A couple of recent studies have tried to shed light on these questions, but they have raised more questions than they have answered. Read more »

In his new book Breakthrough! How the 10 Greatest Discoveries in Medicine Saved Millions and Changed Our View of the World, Jon Queijo describes what he believes are the 10 greatest discoveries. Nine of them are uncontroversial discoveries that have been on other top-10 lists, but his 10th choice is one that no other list of top discoveries has ever included.
Queijo realizes this, and even admits in his introduction that a former editor of the New England Journal of Medicine refused to review his book because there is no such thing as alternative medicine, only treatments that work and treatments that don’t. But he “respectfully disagrees.” Read more »

A new product, Dream Water, is designed to help one relax, fall asleep and improve the quality of sleep using the “perfect blend” of all-natural ingredients melatonin, GABA and 5-HTP (tryptophan).
A single-dose 2.5-ounce bottle retails for $2.99. They also offer a more dilute formulation in an 8-ounce bottle. They suggest drinking half a bottle, keeping it at your bedside, and drinking more if you wake up during the night.
What dosage will you get from half a bottle? From a whole bottle? There’s no way to know. They offer a money-back guarantee, free shipping, free samples, and lots of testimonials. But they refuse to disclose how much of what is in their product. Read more »

One night in 1882, a critically ill 70-year-old woman was at the verge of death at her daughter’s home, suffering from fever, crippling pain, nausea, and an inflamed abdominal mass. At 2:00AM, a courageous surgeon put her on the kitchen table and performed the first known operation to remove gallstones. The patient recovered uneventfully. The patient was the surgeon’s own mother.
This compelling story is the beginning of an excellent new biography of William Halsted, the father of modern surgery, Genius on the Edge: The Bizarre Double Life of Dr. William Stewart Halsted, by Gerald Imber, M.D. Read more »

When I first heard that a retrovirus had been identified as a possible cause of chronic fatigue syndrome, I withheld judgment and awaited further developments. When I heard that two subsequent studies had failed to replicate the findings of the first, I assumed that the first had been a false alarm and would be disregarded. Not so.
It’s a classic case of wishful thinking outweighing good judgment. One unconfirmed report of an association between the XMRV virus and chronic fatigue syndrome (CFS) resulted in a rush to test for the virus, speculation about possible implications, and even suggestions for treatment. And the subsequent negative studies did little or nothing to reverse the trend. Read more »
