A 20 year study has revealed that when junk food prices rise, people eat less of it. A 10% increase in the price of soda or pizza was associated with a 7% drop in buying soda and 11.5% drop in eating pizza. A $1.00 increase in the price of both soda and pizza led to lowered energy intake, weight loss, and an improvement in insulin resistance.
