                                According to the FDA, food manufacturers are permitted a 20% margin of error on the calories stated on nutrition labels, adding a layer of complexity to tracking intake. Understanding what 150 calories per serving actually means requires a closer look at the label, as this figure is tied directly to the specific portion size, not the entire package.
