Many Foods' 'Trans-Fat-Free' Claims False: Study

Many processed foods contain more trans-fats than you might suspect, according to a New York City health department study.

That's because many of the products that claim to be trans-fat-free actually contain some of the unhealthy fats. The researchers examined 4,340 top-selling packaged foods and found that nine percent had trans-fats, NBC News reported.

Of the foods found to have trans-fats, 84 percent said they had 0 grams of the artery-clogging substance, according to the study in the journal Preventing Chronic Disease.

"This labeling is cause for concern because consumers, seeing the 0 g trans-fat on the Nutrition Facts label, are probably unaware that they are consuming trans-fat," wrote Jenifer Clapp, of the New York City Department of Health and Mental Hygiene, and colleagues, NBC News reported.
