The serving size listed on a food label is a standardized amount to help you compare the nutrition content of various foods. This serving size doesn't mean it's the amount you should necessarily consume; that will depend on your hunger, activity level, health needs, and personal preferences. It's a good starting point, though, especially because we're used to eating large amounts of food, and understanding a serving size can help us eat more appropriate amounts of food especially if we're trying to lose weight.
