Grabbing a burger and a doughnut may seem cheaper than downing a daily dose of fruits and vegetables, but that may not always be true, according to the U.S. Department of Agriculture.
Price depends on how you measure it, according to a new USDA report. When factored by calorie, a cookie will more often than not cost less than a red bell pepper.
Most previous studies have calculated cost by measuring food energy – or the price per 100 grams divided by the number of calories present. But the measure doesn’t account for the amount of food consumed or accurately predict out-of-pocket expenses, according to the authors of the study.
Consider skim milk, which has half the calories of whole milk. The price-per-calorie is much higher for the former, though the listed shelf price is often the same for both.
