Milk products have a low glycaemic index (GI) but a high insulinaemic index (II), meaning they elicit an insulin response similar to white bread despite low blood glucose impact.

Be aware that while milk has a low glycaemic index, it can still stimulate a significant insulin response. This is due to milk proteins, not lactose. For most people, this is not a concern, but those monitoring insulin levels should be aware of this discrepancy.

ModerateQualifiesMEDIUM confidence
Consequently, milk products elicited elevated IIs, indistinguishable from a white bread reference meal, despite GIs in the lower range.
