Did you know 2/3s of Americans are overweight or obese? There are many aspects to obesity: not enough exercise, drinking extra calories, frequent fast food, high-calorie snacking, etc. But a study reports a disconnect between serving size listed on a package label and how much folks actually eat.In a survey of 2,500 adults, 25% admitted eating an entire product that was supposed to serve 2-3 people. And frozen meals designed to serve 4 are frequently eaten by one person. That means MORE calories, fat, sodium and sugar are consumed than what is listed on the package label.One serving of canned soup = half the can. So if you eat the entire can, which is what most people do, then you can double the amount of sodium that you take in. And with most soups, that’s probably over 1,500 mg – an entire day’s worth of sodium.What’s in a serving size? A 100-calorie serving of cookies may sound reasonable – but if you eat four servings, then you’retaking in 400 calories. Similarly, an 8-oz serving of soda at 120 calories doesn’t sound too bad – but if you drink the entire bottle (not just 8-oz!), then you’ve actually consumed 480.Calories add up quickly.The serving size listed on a label is not a suggestion for you to eat that portion, but to realize that the calories, sodium and other nutrients listed are for that portion. If you eat or drink more, you will increase the calories and other nutrients also. This may sound like common sense but a lot of folks miss this important distinction when choosing their snacks.
