Om nu tabellen på
http://www.mendosa.com/insulin_index.htm stämmer, där brown rice har ett GI på 104 men ett II på låga 62 så verkar det faktiskt så. Som han skriver:
"At the present time, we don't know how to interpret this type of response (low glycemia, high insulinemia) for long-term health. It may be a good outcome because the rise in insulin has contributed to the low level of glycemia. On the other hand, it may be not-so-good, because the increased demand for insulin contributes to beta-cell "exhaustion" and the development of type 2 diabetes. Until studies are carried out to answer these types of questions, the glycemic index remains a proven tool for predicting the effects of food on health. "
Det borde gälla "åt andra hållet" också.
