In the United States many regulations and policies steer people toward certain dietary practices and away from others—nearly always with the backing of some powerful, entrenched, monied interest and nearly always for no good reason whatsoever. For instance, writes Baylen Linnekin, government subsidies pay farmers to produce some foods in lieu of others. Think corn, soy, dairy, and sugar. The latest example comes from North Carolina, where state officials say one man's blog, which promotes the "paleo" diet, runs afoul of North Carolina laws requiring a license to dispense anything the state considers dietary advice. Linnekin explains why the government has no business interfering with our dietary practices.
