Dumbest Glycemic Index Study Ever?

   At first I thought [1]this was interesting:

     Diets that distinguish between "good carbs" and "bad carbs," are
     not an effective way of controlling blood sugar levels, a new study
     suggests.
     ...
     The new study, published in the February issue of the British
     Journal of Nutrition, relied on food questionnaires from more than
     1,000 people over five years and assessed their consumption of
     high- and low-glycemic foods. Researchers tested their blood sugar
     levels twice during the study period and found no significant
     correlation between the glycemic index of foods and the blood-sugar
     levels of participants.

   After reading that last part I could only laugh at the silliness of
   the study. The whole point of the glycemic index is the short-term
   effect on blood sugar. If you wanted to challenge the benefit of a low
   glycemic index diet, you'd have to test blood sugar levels at least
   twice a day, not twice in the course of five years.
   As Glenn is wont to say, sheesh.
