Link between mothers' poor diets, kids' obesity
New work may have found the missing link between mothers' diets and obesity in kids. A study published in the June issue of Cell Metabolism suggests that a hormone may explain the connection between mothers who are poorly nourished and an increased risk of obesity in their children.
