From Divine Caroline:
Over the past few decades, portion sizes of everything from muffins to sandwiches have grown considerably. Unfortunately, Americaâ€™s waistbands have reacted accordingly. In the 1970s, around 47 percent of Americans were overweight or obese; now 66 percent of us are. In addition, the number of just obese people has doubled, from 15 percent of our population to 30 percent.
While increased sizes havenâ€™t been the sole contributor to our obesity epidemic, large quantities of cheap food have distorted our perceptions of what a typical meal is supposed to look like. These portion comparisons, adapted from the National Heart, Lung, and Blood Instituteâ€™s (NHLBI) Portion Distortion Quiz, give a visual representation of what sizes used to be compared to what they are today.
