Trans Fat Ban in NYC Can Act as Model For Making Healthier Food Supply

While needing commercial food enterprises to replace trans fats with oils and spreads that are low in trans and saturated fats, New York City gives a good template for commencing public health measures to boost the quality of meals bought outside the home, Alice H. Lichtenstein, DSc, of Tufts University Nutrition Scientist pens in an editorial published on July 17 in the Annals of Internal Medicine.

"What New York City's trans fat ban has done is force the removal of unhealthy fats from foods that are eaten on a daily basis by many people," says Lichtenstein, the director of the Cardiovascular Nutrition Laboratory at the Jean Mayer USDA Human Nutrition Research Center on Aging and the Gershoff professor at the Friedman School of Nutrition Science and Policy, both at Tufts University. "Creating a healthier default option is a powerful tool to improve diet quality independent of someone''s health literacy, awareness and motivation, or level of nutrition knowledge."


The editorial appears alongside a New York City Department of Health & Mental Hygiene study that compares the trans fat content of fast food purchases before and after the 2007 ban went into effect. The authors report a significant decrease in trans fat content in foods purchased in 2009.

"Importantly, the results were consistent at all restaurants surveyed, regardless of their locations, meaning that patrons at all income levels benefitted -and not just those who could afford to pay for a healthier option," Lichtenstein said. "Prior to the ban, one of the initial concerns was that the replacement of partially hydrogenated oils would drive up food prices and operational costs, but there is no evidence that this has occurred."

The trans fat ban applies to New York City restaurants. It prohibits them from using partially hydrogenated oils and spreads that contain more than 0.5 grams of trans fat.
"Having a default option takes some of the stress of making healthy choices from the consumer, and this strategy could succeed where other population-wide initiatives, such as dietary guidelines or recommendations, have fallen short," Lichtenstein said. "The preliminary findings suggest that New York City's approach is worth pursuing for this and other nutrition interventions."

Lichtenstein underscores that a major contributor to the success of the public health initiative was New York City's carefully planned approach to the ban, which was implemented in two phases and was complimented by a strong education and support component. "New York City went beyond legislating a change. They supported food workers affected by the ban with concrete help translating the mandated changes into practice," she said. "They set up a telephone help hotline to field technical questions, offered trans fat 101'' courses in English, Spanish and Chinese to educate these involved and created a comprehensive website with guidance for preparing trans fat-free foods."

While Lichtenstein considers the health department's preliminary results very promising, she acknowledges that more data are needed to fully understand the impact of trans fat bans on public health. "One caveat is that most Americans consume far too many calories, particularly relative to their levels of physical activity," she added. "It is important to keep in mind that simply removing trans fat from an item does not decrease the caloric content. It is just one step toward improving the nutritional quality of the food. There should be no mistake, eating too many calories, even if they all come from healthy foods, "will result in weight gain."

The Gerald J. and Dorothy R. Friedman School of Nutrition Science and Policy at Tufts University is the only independent school of nutrition in the United States. The school's eight degree programs, which focus on questions relating to famine, hunger, poverty, and communications, are renowned for the application of scientific research to national and international policy. For three decades, the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University has studied the relationship between good nutrition and good health in aging populations. Tufts research scientists work with federal agencies to establish the USDA Dietary Guidelines, the Dietary Reference Intakes, and other significant public policies.
