Substituting Refined Grains with Whole Grains During Gestational Diabetes Linked with Less Childhood Obesity

Foods that moms choose during pregnancy may have an impact on their children’s health down the line. In a study of more than 500 mother-child pairs in Denmark, in which all of the moms were diagnosed with gestational diabetes (diabetes during pregnancy), Harvard researchers found that substituting 1 serving of refined grains per day with whole grains in the mom’s diet during pregnancy was associated with a 10% lower risk of the child being overweight or obese at age 7. They also found that eating more than 4.3 servings of refined grains per day during pregnancy was linked with nearly double the risk of children becoming overweight or obese at age 7 compared to those who ate fewer than 1.8 servings of refined grains per day. These results were especially strong in kids who were breastfed for less than 6 months.
