Food-specific morning and night intake scores are associated with impaired glucose tolerance during pregnancy.

ABSTRACT:

Background

Impaired glucose tolerance (IGT) during pregnancy is associated with numerous short and long-term adverse health outcomes. Diet is a key factor influencing glucose tolerance, yet there is little data on the relationship between specific foods or intake timing and IGT.
