Let me spell it out for you: true, a type one diabetic will have to take some insulin to control their blood sugar regardless of their diet, however, the more carbohydrates they eat, the more insulin they will have to take. The unfortunate reality of this disappointing conflict of interest is that the de facto customers of the ADA, WDF, and others, are insulin manufacturers, not diabetics.
And while the Juvenile Diabetes Research Foundation does not provide diet or treatment advice to diabetics, its chapters are free to fund their events as they see fit. Here's a picture of a recent JDRF promotion. Does that seem right to you?
