By Lisa Rapaport (Reuters Health) – For women who develop diabetes during pregnancy, low-carbohydrate diets may not necessarily help keep the disease at bay after the baby arrives, a U.S. study suggests. Researchers found that women eating diets high in animal proteins and low in carbs actually raised their diabetes risk. A low-carb diet that was heavy in plant-based protein and fat, in contrast, wasn’t linked to an increased risk of diabetes in the study.
