Could “low-fat” diets be on the way out?

Kristin Wartman, on the Huffington Post:

“The low-fat trend finally appears to be on its way out. The notion that saturated fats are detrimental to our health is deeply embedded in our Zeitgeist–but shockingly, the opposite just might be true. For over 50 years the medical establishment, public health officials, nutritionists, and dietitians have been telling the American people to eat a low-fat diet, and in particular, to avoid saturated fats. Only recently, have nutrition experts begun to encourage people to eat “healthy fats.”

This past December, the Los Angeles Times reported that excess carbohydrates and sugar, not fat, are responsible for America’s obesity and diabetes epidemics. One of the lead researchers in this field, Dr. Frank Hu, professor of nutrition and epidemiology at the Harvard School of Public Health, said, “The country’s big low-fat message backfired.

Doing drugs such as cocaine and eating too much junk food both gradually overload the so-called pleasure centers in the brain, according to Paul J. Kenny, PhD, an associate professor of molecular therapeutics at the Scripps Research Institute, in Jupiter, Fla. Eventually the pleasure centers “crash,” and achieving the same pleasure—or even just feeling normal—requires increasing amounts of the drug or food, says Kenny, the lead author of the study.
