The same scurvy-ish negligence shows up at every level of government. From marketing rules to antitrust regulations to international trade agreements, U.S. policy has created a food system that excels at producing flour, sugar and oil but struggles to deliver nutrients at anywhere near the same scale. The United States spends $1.5 billion on nutrition research every year compared to around $60 billion on drug research. Just 4 percent of agricultural subsidies go to fruits and vegetables. No wonder that the healthiest foods can cost up to eight times more, calorie for calorie, than the unhealthiest—or that the gap gets wider every year.
