Evidenced-Based Nutrition for Gestational Diabetes Mellitus

Area of Science:

• Obstetrics and Gynecology
• Nutritional Science
• Endocrinology

Background:

• Gestational diabetes mellitus (GDM) affects maternal and fetal health.
• Dietary interventions are a cornerstone of GDM management.
• Evidence on optimal dietary approaches requires ongoing review.

Purpose of the Study:

• To synthesize the latest evidence on dietary interventions for GDM treatment.
• To evaluate the efficacy and safety of various dietary strategies in GDM management.

Main Methods:

• Systematic review of high-quality evidence.
• Analysis of data from multiple systematic reviews and recent studies.

Main Results:

• Low-carbohydrate and calorie-restricted diets show no major advantages.
• Low glycemic index (GI) diets are associated with reduced insulin use and macrosomia risk.
• Mediterranean diet safety is suggested, but efficacy requires further trials.
• Insufficient data exists for ketogenic diet safety in GDM.
• Liberalized carbohydrate intake may improve adherence and outcomes.

Conclusions:

• The low GI diet may improve maternal and neonatal outcomes in GDM.
• Further research is essential to determine the optimal, sustainable, and acceptable medical nutrition therapy for GDM.
• Dietary approaches should consider cultural adaptability and long-term adherence.
