Answer:
Creating a delicious product is no easy feat, but more often than not, the process is infused with creativity, excitement, and of course, lots of tasting. Determining the serving size of a food product, on the other hand, is a lot less fun (and certainly less satiating) for food manufacturers. The measuring, the math, and the many FDA guidelines with respect to serving size can all be a little overwhelming.
By definition, serving size is the quantity of a particular product that is meant to be consumed in one sitting based on an average 2,000 calorie per day diet. This quantity helps consumers visualize or measure the amount they should eat at once. On nutrition facts panels, the serving size also gives context to the nutritional profile of the food product, as the calories, macronutrients, vitamins, and minerals displayed represent those present in a single serving.
