According to data analyzing packaged foods in the US, what deviation in caloric content from the label claim was noted in up to 20% of items?
Answer
A deviation of more than 20%.
One significant challenge facing modern, meticulous calorie counters is the inherent variability and potential inaccuracy of input data provided on food labels. Studies examining packaged foods within the United States revealed that a substantial portion, up to 20% of tested items, exhibited caloric content that deviated by more than 20% from what was officially claimed on the packaging. This deviation could be either an over- or underestimation. This variability means that even perfect adherence to a calculated dietary plan can result in unintentional calorie surpluses or deficits, undermining the perceived precision of the counting method.
