Blood glucose response to rate of consumption of digestible carbohydrate



When the glycemic response to consuming digestible carbohydrate is measured, little or no attention appears to have been paid to the possible effect on this response of the rate at which the food is consumed. We compared glycemic responses when volunteers ate or drank foods containing digestible carbohydrate as rapidly as possible, or in five equal portions over 12 min. Expecting that the response would be greater when the food was consumed rapidly, we found that the responses were equally and randomly distributed between the two rates of eating. At the same time, marked differences were noted in the responses elicited when different individuals consumed the same foods, leading to an investigation of this phenomenon, published elsewhere.
