“Some researchers suggest that may be a good idea, since a new study finds that women who eat more potatoes before conceiving may face a higher risk of developing gestational diabetes while pregnant.
…”We found that a diet with a higher level of potato consumption before pregnancy was related to a greater risk of developing diabetes during pregnancy,” said study author Dr. Cuilin Zhang, senior investigator in the Epidemiology Branch of the Division of Intramural Population Health Research at NIH’s Eunice Kennedy Shriver National Institute of Child Health and Human Development. It’s estimated that about four to eight percent of pregnancies are affected by gestational diabetes, said Zhang.
…The authors also found that when two servings per week of potatoes were dropped in favor of other vegetables, legumes, or whole grain foods, women had a nine to 12 percent lower risk of developing diabetes during pregnancy.”
