 In this review, it was found that healthy diets reduce the risk of gestational diabetes mellitus, GDM, in white European women, but not in other populations. This suggests that diet may be more effective at reducing GDM risk in certain ethnicities than others. Further research is needed to determine if this finding can be replicated in other populations.
