'Soda Tax' Proposed in New York

New York Gov. Paterson proposed an 18 percent sales tax on non-diet sodas and juice drinks in an effort to reduce the state's budget deficit. The tax, which would not affect bottled water, diet soda, coffee, tea or milk, is estimated to raise more than $400 million in the first year.

The beverage industry says the proposal would harm industry jobs in New York. Others are critical of the government’s involvement in food and drink consumption.

"One complaint about the concept of a food tax is that government should keep out of personal behavior such as what people eat. But government is involved in what we eat, often in negative ways," said Kelly D. Brownell, PhD, Rudd Center Director. "It has allowed sugared beverages to be promoted in schools, failed to restrict marketing of unhealthy foods to children (brand loyalty develops early) and subsidizes corn, making it very inexpensive to sweeten beverages with high-fructose corn syrup."

The public health implications of the proposal could be significant.

"More than for any category of foods, research has shown that consumption of sugared beverages is associated with poor diet, increased rates of obesity and risk for diabetes," said Brownell.

Work on price elasticities of soda consumption suggests that an 18% increase in price would lead to a drop in consumption of about 18%. As Brownell notes, there are many unknowns that will have to be examined if the tax is passed in New York. Among these issues are whether companies will lower costs to help offset the tax, consumers will migrate from brand name to generic versions (thus saving money but not improving nutrition), there will be a large switch from sugared to diet beverages and how industry will adjust its marketing practices.

Rudd Center Staff Develops Food Addiction Scale

Yale University researchers are developing a way to assess a person's dependence on food, which can influence treatments for food addiction and food marketing, especially to children.

The Yale Food Addiction Scale would represent the first measurement tool in the field, and is described in a forthcoming article by Ashley Gearhardt, a PhD student in Yale’s Clinical Psychology program, William Corbin, PhD, Associate Professor of Psychology at Yale, and Kelly D. Brownell, PhD, Rudd Center Director. Their article, "Preliminary Validation of the Yale Food Addiction Scale," will be published in the journal Appetite.

Initial findings suggest that the scale can help identify people with addictive inclinations toward food that is high in fat and sugar.

"Evidence is building that excess food consumption can closely resemble substance dependence. For research in this area to progress, it will be necessary to develop well-validated tools to identify those most likely to be experiencing symptoms of dependence," said Gearhardt.

In commenting on this work, Brownell noted, “There is now a critical mass of work on the issue of food and addiction and it looks more and more like certain foods, or constituents of food such as sugar, may be capable of triggering an addictive process. This scale will help clinical researchers examine the concept of dependence more thoroughly.”

When the article on the scale is published, information will be provided in a subsequent newsletter. Information on the issue of food and addiction is available from a Rudd Center Report.

Rudd Center Holds Steering Committee Meeting on Food Marketing to Youth Study

In early December, the Rudd Center and the Robert Wood Johnson Foundation hosted a distinguished group of public health, public policy and marketing experts for the first meeting of the Food Marketing and Childhood Obesity Steering Committee. Kelly D. Brownell, PhD, Rudd Center Director, and C. Tracy Orleans, PhD, Distinguished Fellow and Senior Scientist at the Robert Wood Johnson Foundation, hosted the meeting. The diverse group included leaders in public health research in the fields of economics, medicine, nutrition and the law; officials responsible for public health at the local and national government levels; members of the Institute of Medicine (IOM) Standing Committee on Childhood Obesity Prevention and the IOM Food Marketing to Children taskforce; experts on health promotion in African-American and Hispanic communities; and experts on childhood obesity. Staff from the Robert Wood Johnson Foundation and the Rudd Center Senior Leadership Team and Marketing Group also attended.

The goal of the meeting was to obtain expert advice about project plans for the Rudd Center’s $6.4 million grant from the Robert Wood Johnson Foundation to study food marketing and childhood obesity. The meeting involved discussions of key issues related to the project. The key issues included methods to evaluate the nutritional quality of foods marketed to youth and the tactics used to market them, how to measure youth exposure to food marketing across all media and how to interact with the food industry to encourage them to reduce the harm associated with food marketing to youth. The committee also discussed strategies to assess racial and ethnic disparities in exposure to food marketing and ways to educate policy makers about food marketing to children.

According to Brownell, “The level of enthusiasm and support for the project among the steering committee members was extremely encouraging. In addition, the suggestions and insights they provided will be invaluable in our ongoing implementation of the project and our ability to positively impact public health.”
