Impacts of dietary fat changes on pregnant women with gestational diabetes mellitus: a randomized controlled study.
OBJECTIVE This study aims to determine the impact of increasing polyunsaturated fatty acid intake on blood glucose , lipid metabolism , and pregnancy outcomes of pregnant women with gestational diabetes mellitus . METHODS Under constant total energy and protein intake , 84 pregnant women with gestational diabetes mellitus were r and omly divided into the experimental and control groups , which were given oil-rich and conventional low-oil meals , respectively . RESULTS After the dietary intervention , the intake and energy supply of fat and the three fatty acids were significantly higher in the experimental group than the control group ( p<0.001 ) . The intake and energy supply of polyunsaturated fatty acids  increased significantly post-intervention in the experimental group but did not change in the control group . In both the intervention and the control group , fasting blood glucose , 2 h postpr and ial plasma glucose , and the insulin resistance index decreased significantly post-intervention ( p<0.05 ) ; the lipid changes were consistent between groups . Pregnancy outcomes did not differ significantly between the two groups ( p>0.05 ) . CONCLUSIONS An appropriate increase in polyunsaturated fatty acid intake benefits pregnant women with gestational diabetes mellitus as well as fetuses , as long as the diet therapy follows basic recommendations and total energy intake is strictly controlled
