TOO FAT? Maybe it’s time to blame the feds.

Instead of nagging ... the feds ought to consider how their own policies have contributed to Americans’ expanding girth.

Science journalist Gary Taubes said federal advocacy for a low-fat diet, starting in the ’70s, helped shift Americans toward a diet emphasizing the carb-heavy bottom of the USDA food pyramid. “We ate more fat-free carbohydrates,” Taubes wrote, “which, in turn, made us hungrier and then heavier.”

Farm subsidies were a major contributing factor. Take the Twinkie, food journalist Michael Pollan wrote, it’s “basically a clever arrangement of carbohydrates and fats teased out of corn, soybeans and wheat — three of the five commodity crops that the farm bill supports.”

Local produce, organic food, farmers markets, and your backyard garden? In the name of food safety, be gone.
