High glycemic index (GI) meals require 1.5-fold more insulin to maintain similar glycemia compared to low GI meals.
Practitioners should consider the increased insulin needs when recommending high GI foods to individuals with T1D.
StrongSupportsmedium confidence
In a controlled feeding study, a high GI meal was associated with a 1.5-fold higher insulin requirement to obtain similar glycemia.
Why this rating
Based on the controlled feeding study design mentioned in the abstract.
