Are All Carbs Equal?

In How Carbs Can Trigger Food Cravings, some of Taubes' ideas get a further airing:

• Sugary foods and drinks, white bread and other processed carbohydrates that are known to cause abrupt spikes and falls in blood sugar appear to stimulate parts of the brain involved in hunger, craving and reward, the new research shows. The findings, published in The American Journal of Clinical Nutrition, suggest that these so-called high-glycemic foods influence the brain in a way that might drive some people to overeat.
  
  For those who are particularly susceptible to these effects, avoiding refined carbohydrates might reduce urges and potentially help control weight, said Dr. David Ludwig, the lead author of the study and the director of the New Balance Foundation Obesity Prevention Center at Boston Children’s Hospital.

 It has been known for some time that isocaloric is not isometabolic so these ideas shouldn't really come as a surprise to long time readers.
