That’s what University of Washington researchers found when they compared the prices of 370 foods sold at supermarkets in the Seattle area. Calorie for calorie, junk foods not only cost less than fruits and vegetables, but junk food prices also are less likely to rise as a result of inflation. The findings, reported in the current issue of the Journal of the American Dietetic Association, may help explain why the highest rates of obesity are seen among people in lower-income groups."
