retail news in context, analysis with attitude

The Wall Street Journal reports that it may not just be the saturated fat and cholesterol in red meat that could be a health risk, and that a study published in Nature Medicine points to carnitine, described as "a compound abundant in red meat that also is sold as a dietary supplement and added to energy drinks" as being a potential problem.

According to the story, "Carnitine typically helps the body transport fatty acids into cells to be used as energy. But researchers at the Cleveland Clinic found that in both humans and mice, certain bacteria in the digestive tract convert carnitine to another metabolite, called TMAO, that promotes atherosclerosis, or a thickening of the arteries."

The story goes on to say that "the new findings don't mean that red meat is more hazardous than previously thought, but they may help explain the underlying risk."

Critics of the study say that it is just an "emerging hypothesis," and that large conclusions are being drawn from small studies.

Suddenly, I'm glad I had a tuna steak last night, marinated in a nice Thai Ginger Sauce and cooked with onions.
