But what is the most important thing on those nutrition labels for you to know? Quite simply, the most important thing on the label for you to know is the serving size! Everything else is based on that knowledge. All the other numbers are per serving! You may notice 15g of sugar, for example, and think that's not bad. But is that for the whole bag, can, etc, or for 1/2 cup, 10 chips, etc? Make sure the first thing you read is the serving size and then apply that to the other numbers based on how many servings you are going to eat!
