But type 2 diabetes is not characterized by glycemic load. It is characterized by insulin resistance. Reducing intake of sugars, such as the amylose in rice, reduces the accumulation of blood glucose, but it does not reduce the insulin resistance which causes the buildup of blood glucose. Insulin resistance is more tied to carbohydrates like wheat which introduce dangerous opioid proteins.

Glycemic load is merely the study author's opinion of a marker. Reducing rice would reduce glycemic load, but would do nothing about insulin resistance.

....meaning rice in moderation is a lot healthier than 99% of alternative carbohydrates.
