Gestational Diabetes, Obesity, Pregnancy, High Risk
Conditions
Brief summary
The purpose of this clinical study is to collect baseline information on dietary habits and metabolic risk factors, and to examine the effects of a dietary intervention focusing on fiber and antioxidant rich berries on the development of gestational diabetes, maternal glucose and lipid control and inflammation in obese pregnant women at risk of developing diabetes. With the ongoing epidemic of obesity, the prevalence of gestational diabetes is significantly increasing and the goal of this research is to identify optimal dietary strategies that can reverse this condition or control the rise in blood glucose among those with already developed diabetes.
Interventions
