Meal size is important

So yesterday we spoke about the "value" of food . . . and what's considered "junk food" and what's not . . .
We also spoke about "EMPTY CALORIES" . . . (which we'll continue with tomorrow)
But today . . . we need to ask the question . . . what's the difference between "serving size" and "portion size" . . . and why does it matter???
Well . . . "Serving" size is the amount of food listed on a product's package's Nutrition Facts label.
Whereas . . . "Portion" size is how much food you "choose" to eat at one time.
Okay . . . so a good example would be a bag of "chips" . . .
A "serving" size is what that bag of chips states on the label . . . like 15 chips per serving . . .
But . . . eating directly out of that bag of chips . . . will most likely turn into eating more than the "serving" size . . . and now "that" becomes a "portion" size because you just ate more than 15 chips per serving.
And with this . . . it almost always leads to overeating.
Okay . . . so did you know that the U.S. Food & Drug Administration updated the "serving size" on labels to "reflect" the amount people "typically" eat and drink today???
Another good example would be with soda . . . the "serving" size has been changed from 8 ounces to 12 ounces to accommodate the fact that "we" as the consumers. . . drink more soda today than we did when the FDA originally set up the "serving" size guidelines.
Or what about ice cream???
