Potato Extract-Based Dietary Supplement Could Someday Solve Obesity Problem

December 20, 2014: 12:00 AM EST
A Canadian study in mice found that potato extract can prevent weight gain from a diet high in fat and refined carbohydrates. For the study, the researchers fed the mice an obesity-inducing diet for 10 weeks. Mice in the control group went from 25 grams to 41 grams. But those fed the potato extract – roughly equivalent to eating 30 potatoes – gained only seven grams. The reason for the difference is the high concentration of polyphenols, a beneficial chemical component of fruits and vegetable. The investigators don’t advise eating 30 potatoes a day, of course, but instead envisage creating a potato extract dietary supplement or kitchen cooking ingredient.
