Is it true that the FDA allows actual nutrient content to differ from nutrition label values by up to 20 percent?

Yes. One peer-reviewed study states that under FDA regulation the nutrition labeling law allows a 20% deviation for all nutrients and product weight, and a separate study notes most sampled products fell within the allowable 20% over label calories per FDA regulations.
