Soy protein improves the health status of women with gestational diabetes

Gestational diabetes mellitus (GDM) is a frequent medical condition that is defined as impaired carbohydrate and fat metabolism which has an impact on the insulin resistance and dyslipidemia during pregnancy. Estimates are that the prevalence of GDM ranges from 1.7 to 11.6%. New evidence suggests adding soy protein to the diet of women with GDM may result in pronounced health benefits. Women were randomly assigned to receive either a control diet containing 0.8 g/kg protein (70% animal and 30% plant proteins) or a soy diet containing the same amount of protein with 35% animal protein, 35% soy protein, and 30% other plant proteins for 6 weeks. Textured vegetable (soy) protein provided 15 g protein and 75 mg isoflavones. Compared to the control diet, the soy diet favorably affected fasting plasma glucose levels, insulin levels, insulin resistance, triglyceride levels and antioxidant capacity.   In addition, soy protein consumption reduced the incidence of newborn hyperbilirubinemia and hospitalizations.
