If you had to take a guess about the biggest difference between food back in the 1950s and today, what would your answer be? Two words: Portion size. The CDC reports that restaurant portions have quadrupled since the 1950s—in fact, according to a new analysis from the RAND corporation and published in the journal Public Health Nutrition, 96% of restaurant portions exceed dietary guidelines for sodium and fat. Could this be contributing to the high rates of obesity in the US and in Yakima County? In Yakima County, 31% of adults are obese – higher than the state average of 26%. Check out this infographic from the CDC for a look at just how drastically things have changed.
