That’s the advice from the updated U.S. nutritional guidelines, released Thursday by the Department of Agriculture and the Department of Health and Human Services. The guidelines are published every 5 years and aim to reflect the latest science-based evidence about what we eat.
“Diet is one of the most powerful tools we have to take control of our own health,” Health and Human Services Secretary Sylvia Burwell told reporters at a briefing Thursday. “There are many ways to stay healthy, but nutrition will always be at the foundation of good health.”
While some groups like the American Medical Association praise and support the guidelines, critics say the recommendations don't go far enough -- and they've accused the government of playing politics with Americans' health.
"It really is a betrayal of science to politics," says David Katz, MD, founding director of the Yale Prevention Research Center, a federally funded program that studies how changes to lifestyle can prevent disease. "Public health, which means the lives of real people, is being thrown under the political bus."
Some of the biggest controversy centered on what wasn't in the guidelines -- a recommendation to eat less red and processed meat. The Dietary Guidelines Advisory Committee, a panel of independent experts, called eating large amounts of red and processed meat “detrimental.”
The guidance does recommend we eat lean meats and poultry, and it notes that eating less meat, including processed meat and processed poultry, has been linked to a lower risk of heart disease. But it doesn’t offer specific instructions or limits around red and processed meats. Choices can include processed meats and processed poultry, as long as eating patterns stay within the limits for sodium, saturated fats, added sugar, and calories recommended by the new guidelines.
"The science on the link between cancer and diet is extensive," says Richard Wender, MD, chief cancer control officer for the American Cancer Society. "By omitting specific diet recommendations, such as eating less red and processed meat, these guidelines miss a critical and significant opportunity to reduce suffering and death from cancer."
