Since 2001, the number of health claims on packages has gone up again. Martinez attributes that to companies trying to market to people's increased awareness of health issues and weight loss, which he measured by counting the number of obesity-related programs aired on major TV news channels. In 2010, 43 percent of new foods had some kind of nutrition claim. On average, foods with at least one claim were actually healthier than packaged foods in general, Martinez found. Foods with claims also tended to sell better.
