How accurate are nutrition labels?
Unfortunately, Nutrition Facts labels are not always factual. For starters, the law allows a pretty lax margin of error—up to 20 percent—for the stated value versus actual value of nutrients. In reality, that means a 100-calorie pack could, theoretically, contain up to 120 calories and still not be violating the law.
