According to a recent study:
In related news, it turned out that low-nutrient, calorie-rich foods -- mainly sweets and snack foods -- were far more expensive, nutrient for nutrient, than fruits and vegetables.
Using retail prices at major supermarket chains in Seattle, researchers at the University of Washington found that low-calorie, nutrient-rich foods -- mainly fruits and vegetables -- were far more expensive, calorie for calorie, than sweets and snack foods.
They found that snack foods, sweets and fatty foods offered the most bang for a shopper's buck. Whereas the price of the lowest-calorie fruits and vegetables was more than $18.16 per 1,000 calories, the most calorie-rich foods cost $1.76 per 1,000 calories.
The following, however, is a non-sequitur:
The fact that calorie-rich foods are cheaper per calorie will influence behavior only if you assume that the consumers are buying a given number of calories and trying to spend as little as possible. It might explain vitamin deficiencies but it cannot explain a calorie surplus by itself.
The findings, published in the Journal of the American Dietetic Association, highlight a key obstacle to healthy eating. And they may help explain why obesity rates are highest among the poorest Americans, according to the researchers.
"Whereas (calorie)-dense foods remain the most affordable option, the price of the recommended healthful foods of lower (calorie) density has disproportionately increased," write Drs. Pablo Monsivais and Adam Drewnowski.
