Popular Misconception Mashed
Research from scientists at the University of California, Davis has mashed the notion that potatoes cause weight gain. The researchers tested 90 overweight people divided into three groups, with all of them eating five to seven servings of potatoes each week over a three-month period.
Two groups reduced their calorie intake by 500 calories per day, with one group eating low-glycemic index (GI) foods and the other group eating high-GI foods. The third group had no calorie restrictions. Despite the increased potato consumption during the study period, all three groups showed slight weight loss and reduced body mass index.
The researchers concluded, “Potato intake did not cause weight gain.”
