Thirty years ago, kids ate just one snack a day, whereas now they are trending toward three snacks, resulting in an additional 200 calories a day. And one in five school-age children has up to six snacks a day.
Portion sizes have also exploded- they are now two to five times bigger than they were in years past. Beverage portions have grown as well- in the mid-1970s, the average sugar-sweetened beverage was 13.6 ounces compared today, kids think nothing of drinking 20 ounces of sugar-sweetened beverages at a time.
In total, we are now eating 31 percent more calories than we were forty years ago–including 56 percent more fats and oils and 14 percent more sugars and sweeteners. The average American now eats fifteen more pounds of sugar a year than in 1970.
