(MCT) — New York City’s pioneering ban on all but the smallest amounts of trans fats in restaurant food has led to a significant reduction in consumption, a change that should translate into better cardiovascular health in the nation’s largest city, according to a new report. It also demonstrates that coffee shops, fast-food joints and other eateries can play a major role in improving the health of the public, the study authors said.

Officials from the New York City Department of Health and Mental Hygiene conducted the study to assess whether the regulation that took effect in 2008 — which prohibits all restaurants from serving food prepared with partially hydrogenated vegetable oil or dishes that contain more than 0.5 gram of trans fat per serving — was making a difference for diners.
