WASHINGTON (AP) — Congressional Republicans are pushing back against proposed dietary guidelines that urge Americans to consider the environment when deciding what foods to eat.
House and Senate spending bills approved by subcommittees in each chamber say the guidelines must focus only on nutrition and diet. That’s a clear effort to thwart a recommendation by the Dietary Guidelines Advisory Committee that eating a diet higher in vegetables and other plant-based foods is better for the environment than eating a diet based on foods from animals.
This advice from a government advisory panel of independent doctors and nutrition experts has raised the ire of the meat industry.
The dietary guidelines come out every five years, and the government advice informs everything from school lunches and food package labels to advice from your doctor. The departments of Agriculture and Health and Human Services are expected to issue a final version by year’s end based on the advisory committee’s February recommendations.
While the guidelines always have been subject to intense lobbying by food industries, this year’s version has set off unprecedented political debate, fueled by Republicans’ claims the Obama administration has gone too far in telling people what to eat.
The advisory panel also suggested a tax on sugary drinks and snacks as one way people could be coaxed into eating better. That idea angered beverage companies and conservatives in Congress.
Two spending bills in the House set a new threshold for the science that can be used in setting the guidelines, saying the government only can make recommendations based on the strongest science.
The guidelines panel had used three grades to determine the strength of the science supporting its recommendations: Grade 1 is strong, Grade 2 is moderate and Grade 3 is limited.
The advisory committee sent a letter to lawmakers Tuesday strongly opposing the legislation.
“I don’t think public policy should be driven by the economic interests or the lobbyists,” panel chairman Barbara Millen said in an interview. “It needs to be driven by science, and good science.”
Millen said “strong” recommendations are unlikely to change over the years and are much harder to come by with limited research dollars.
The recommendation that a more plant-based diet is better for the environment is based on science rated moderate in the report. The moderate threshold means there’s a strong body of scientific evidence to support the recommendation, but it’s not as conclusive, Millen said.
“Research evolves and we expect it to change,” she said. “That doesn’t negate the importance of a large body of consistent data that may have limitations of a certain kind.”
A spokesman for Rep. Robert Aderholt, the author of one of the House bills, says the language in the legislation was intended to be a threshold, not to benefit one group over another. Aderholt, R-Ala., also has pushed back against healthier school lunch rules, and his bill tries to delay federal menu labeling requirements.
The bill has frustrated groups such as the American Cancer Society, which says the legislation could strip the dietary guidelines of a recommendation that reducing consumption of red meat and processed meats can lower the risk of colon cancer. The cancer society’s own guidelines have long urged people to take the same step.
“We wouldn’t make that recommendation in our own guidelines if we didn’t feel that the evidence was convincing,” said Gregg Haifley of the American Cancer Society Cancer Action Network.
Different medical organizations use a variety of definitions for when there’s enough evidence to back public health guidelines. However they label it, the common idea is that the preponderance of evidence to date supports the recommendation.
Based on the Grade 1 parameters, the guidelines also may be prevented from making recommendations on physical activity, including advising increased exercise based on its benefits for heart health and other disease prevention. It could also prevent the panel’s recommendations on package labeling and health and wellness in the workplace.
A Senate bill overseeing spending for the Health and Human Services Department is more vague, saying the guidelines must be “based only on a preponderance of nutritional and scientific evidence and not extraneous information.”
The advisory committee should have made “recommendations based on sound nutritional science and not issues they don’t have the authority or expertise to consider,” said Missouri Sen. Roy Blunt, the panel’s Republican chairman, after it approved the legislation Tuesday.
