Understanding Food Labels: Serving Size Tricks to Watch For

The numbers on a nutrition label are always PER SERVING — not per package, and not necessarily a realistic single sitting. This single detail causes more confusion than almost any other part of food labeling.

A common pattern: a bag of chips lists a serving as a small handful, even though most people eat the whole bag in one sitting. A "low calorie" cracker might list an unrealistically small serving size to make the number look better. Always check the serving size FIRST, then check how many servings are actually in the package or container you're about to eat from — multiply the calorie and macro numbers accordingly if you plan to eat more than one serving.

This isn't about distrust of every product, but about reading labels with the right frame: the number on the front of a label (like "120 calories") only means something once you know exactly how much food that number is describing.
