FROM THE USDA AND HHS
The U.S. Department of Health and Human Services and the U.S. Department of Agriculture have released the eighth iteration of the Dietary Guidelines for Americans, a set of recommendations for healthy eating habits Americans should adopt to prevent development of hypertension, heart disease, and type 2 diabetes, among other conditions.
The new guidelines , effective through 2020, highlight the importance of eating a wide variety of fruits, vegetables, grains, and dairy products, while staying away from processed foods heavy in saturated fats, sugar, and cholesterol as much as possible. The difference between this and earlier editions of the guidelines, the health agencies say, is to promote the importance of a wider variety of foods Americans should be consuming, rather than focusing on just a few isolated foods that should be integrated into an otherwise inadequate diet.
“Protecting the health of the American public includes empowering them with the tools they need to make healthy choices in their daily lives,” Secretary of Health and Human Services Sylvia M. Burwell said in a statement. “By focusing on small shifts in what we eat and drink, eating healthy becomes more manageable. The Dietary Guidelines provide science-based recommendations on food and nutrition so people can make decisions that may help keep their weight under control, and prevent chronic conditions, like Type 2 diabetes, hypertension, and heart disease.”
The American Medical Association voiced their support of the new guidelines, saying that they are “extremely pleased that the new recommendations call for significantly reducing the amount of added sugars and sugar sweetened beverages from the American diet.” Similarly, the American College of Cardiology issued a statement saying that the existence of “a source of clear science-based information about diet” is more important than ever for Americans in the face of increasingly omnipresent and often confusing information available; the college also lauded the recommendations to limit the intake of added sugars, saturated and trans fats, and sodium. The American Heart Association released a new Authoritative Review of data on the topic of nutritional balance as it related to chronic diseases.
While the recommendations may seem common sense and geared more towards patients and laymen, they are of equal importance to health care providers. Dr. Carolyn Lopez – a Chicago-area family physician and adjunct professor of medicine at Northwestern University – called the guidelines an important resource for physicians, with several elements that will be of particular benefit to physicians and clinicians looking to improve the quality of care given to their patients.
“People [should] understand that while individual food choices are important, the pattern of eating is paramount,” Dr. Lopez explained in an interview. “It’s not impossible to bring vegetables into breakfast – veggie omelettes are great – but it’s hard to imagine bringing a vegetable into the whole grain cereals with skim milk breakfast.”
As a family practitioner, however, Dr. Lopez stressed the difficulty of any doctor having a significant enough amount of time with each patient to really go in-depth into what needs to be done to enact meaningful nutritional and lifestyle changes. “These guidelines can only be effective if the whole team is talking to patients,” she explained. “On its own, it would be extraordinarily difficult [or] impossible to accomplish.
Dr. Helena W. Rodbard – an internist in Rockville, Md., who is a Fellow of the American College of Physicians (ACP) and a Master of the American College of Endocrinologists (ACE) – stressed the need for health care providers to take the time to actively discuss these guidelines with their patients rather than just giving them a few quick tips at the end of the checkup.
“Most physicians are so rushed nowadays by the health care system that they typically do not have adequate time to discuss these very important issues,” Dr. Rodbard said in an interview. “It takes time and perseverance to educate the patient and provide individualized care, assessing their current diet, assessing their willingness or potential for changing their diet or increasing their physical activity.”
On that last point. Dr. Rodbard criticized the new guidelines for not emphasizing the importance of exercise enough. “More clarity and emphasis on physical activity should have been provided,” she said, adding that “people need continual, gentle reminders with repetition and long-term follow-up.” Dr. Rodbard summed up the guidelines as “marginally adequate” but “a step in the right direction.”
An endocrinologist who practices in Winter Park, Fla., Dr. Victor L. Roberts – a Fellow of the ACP and ACE – agreed that time with the patients is critical in order for these guidelines to have any effect, calling the guidelines “just the GPS, not the destination.”
Preaching an ABC strategy – accountability, behavior, and calories, the latter of which he stressed is the most important part of any dietary strategy – Dr. Roberts explained that clinicians and physicians should leave the more specific dietary advice to nutritional experts and focus on telling their patients to watch calories, watch the amount of food they’re eating of any given type, and to exercise more.
“These guidelines crystallize and summarize what we’ve already known, and what we should have been practicing and advocating, for decades,” Dr. Roberts said in an interview, adding that “the difficulty is putting these recommendations into practice and having patients and doctors accept responsibility.”
Ultimately, all three doctors concur that the new guidelines are imperfect, and likely won’t result in any automatic widespread change. Dr. Rodbard admitted that she does not anticipate the guidelines affecting the way she treats her patients very much, if at all, while Dr. Lopez said that she’s “not sure it’s going to have a major effect.” Furthermore, the sheer volume of data and information available often leads to patients simply not knowing what to believe, which Dr. Roberts described as a “glazed over” effect of being told so many different things from so many different sources, patients just tune everything out.
Ultimately, while it’s important for health care providers to give advice and recommendations as necessary, these should be done on an individual basis. And, if a patient requires extensive dietary and nutritional intervention, that should be left in the hands of specialist who can accurately determine what the patient is capable of, what their goals should be, and how to tailor a plan specifically for them.
“I don’t know many clinicians, even in my own specialty, who know much about what specifically to eat,” said Dr. Roberts. “That should come from nutritional medicine people, not us.”
Dr. Lopez, Dr. Rodbard, and Dr. Roberts did not report any relevant financial disclosures.
