A recently published study in the New England Journal of Medicine found that those who eat more potatoes weigh more than those who don’t.
On average, an extra serving of potatoes per day when compared to the baseline study population’s intake equated to a 1.69 pound weight gain over four years.
Potato chip eaters weighed an average 1.28 pounds more than the less heavy users of potatoes. If potato eating tended to be in the french fried form, that was correlated with a 3.35 pound weight gain.
The study was conducted by researchers at the Harvard School of Public Health and analyzed previous studies of over 120,000 men and women who were not obese when the study started and who were also generally healthy.
Not surprisingly, eating more high fiber foods such as fruits and vegetables, whole grains and nuts was correlated with slight weight loss over the four year study period. Yogurt intake – despite being fiber free in its natural form – also tracked with weight loss.
