GI IN MIXED MEALS
Sugiyama et al. (2003) found that the ingestion of milk with rice resulted in a significantly lower GI than when rice was eaten alone

INDIKASI PEMBERIAN LOW GLYCEMIC DIET
Wolever et al suggest that, in patients with type 2 diabetes on diet alone, a Low-GI diet for 1 year increases disposition index, an index of beta cell function, compared with a Low-CHO diet.
Moses et al suggest that Using a low–glycemic index diet for women with GDM effectively halved the number needing to use insulin, with no compromise of obstetric or fetal outcomes

GLYCEMIC LOAD
GL takes into account how much carbohydrate a serving of a food contains and may be determined by indirect and direct methods.
Indirect methods :GI x the amount of available arbohydrate in the portion offood consumed
Glycemic equivalence is a method of directly determining GL

Hubungan GI dan GL
The relationship between GI and GL is not straightforward;
for example, a high GI food can have a low GL if eaten
in small quantities. Conversely, a low GI food can have a
high GL dependent upon the portion size eaten
