Don’t ask the doc
As I have pointed out in many past issues of Health Yourself, research consistently points to a link between an individual’s nutritional status and chronic disease. The growing list of diet-related diseases and a burgeoning obesity epidemic prove diet regulation is the most important element in the treatment of most lifestyle-induced chronic diseases. In many cases, if diet were skillfully addressed, it could comprise a patient’s entire treatment.
While we know the importance of diet for enhancing overall health, our physicians and health-care providers — the very people most responsible for the direct treatment of disease — lack the adequate education to provide current, science-based nutrition advice to their patients, or even themselves.
In 1895, the famous medical educator W.G. Thompson complained about the lack of nutrition education in his medical textbooks on nutrition. “The subject of the dietetic treatment of disease has not received the attention in the medical literature which it deserves,” he wrote, “and it is to be regretted that in the curriculum of medical colleges it is either wholly neglected or disposed of in one or two brief lectures at the end of a course in general therapeutics.” (Thompson, W.G., 1895 Practical Dietetics with Special Reference to Diet in Disease, D. Appleton & Co., Publ.)
Thompson surely would be dismayed to know that we continue to face a striking absence of funding for nutritional intervention research to study, in a comprehensive manner, the relationship between the foods we consume and the chronic diseases we develop.
On the one hand, we see an increase in preventable nutrition-related diseases (e.g., obesity, diabetes, cardiovascular disease). On the other hand, we have “Internet pseudo-experts” and “quasi-self-prepared” charlatans promoting opinion as fact, guidelines that are moving targets, and a public that relies on nutritional supplements and self-diagnosed remedies as magic cures.
Some seven out of 10 deaths among Americans each year are the result of chronic diseases that could be prevented with proper lifestyle intervention. This fact underscores the need for increased nutrition education among our medical professionals.
Status of nutrition education in U.S. medical schools
Reports between 1979-84 indicate that less than 30 percent of all medical schools required even one course in nutrition. Surely this inadequate state of affairs would improve as nutrition research became more ubiquitous? Well, a follow-up study of all U.S. medical schools in 2004 found no increase in nutrition education. Only 32 schools (30 percent) required medical students to take a separate nutrition course. On average, medical students received between 1-20 contact hours of nutrition instruction out of literally thousands of pre-clinical education hours. Disappointingly, only 40 of the 126 U.S. medical schools required the minimum 25-hour curriculum recommended by the National Academy of Sciences.
The most recent national survey in 2010 of nutrition education in U.S. medical schools is not encouraging. Only about 26 medical schools, just 25 percent of the total (down from 30 percent in 2006), required a dedicated nutrition course. Overall, on average, medical students received just 19.6 contact hours of nutrition instruction during their medical school careers (range: 0-70 hours). And, only 27 percent of all schools met the minimum 25 required hours set by the National Academy of Sciences. It is tough to know how individual schools rank; the researchers at the University of North Carolina who produced the study will not release data on specific programs.
Surveys of nutrition education in Western European medical schools reveal slightly better results; estimates suggest about 69 percent of schools required, on average, 24 hours of nutrition education.
Lack of nutrition
One of the most disturbing aspects of the lack of nutrition training for physicians is the finding that many medical school faculties do not believe more nutrition knowledge is necessary. In 2004, about 88 percent of U.S. medical school faculty thought they needed to include more nutrition education; in 2009 that figure dropped to 79 percent. With the growing demand for greater specialization and supporting education, I would not be surprised that in today’s academic environment even fewer medical school faculty feel more basic nutrition education can be added to an already packed medical school curriculum.
With such poor training in nutrition, it should not be surprising that doctors know less then they think they know about the subject. Of course, most people don’t challenge their health professionals regarding their expertise in nutrition and lifestyle intervention. That would be awkward, right? Well, I’ve done it. And with few exceptions, I’ve been shocked, disappointed, and dismayed.
Actual versus perceived expertise
Based on several studies that tested medical professionals’ knowledge of nutrition and lifestyle change (including physicians in many disciplines), there is an undeniable misalignment of actual and perceived nutrition and lifestyle-modification knowledge, mainly related to diet and exercise. Doctors say they are knowledgeable about nutrition and chronic disease management. However, research shows the majority are getting failing grades in this important area. Test results indicate misinformation and misconceptions regarding lifestyle/nutrition knowledge is endemic among physicians and other medical professionals.
According to a review published in 2010 “virtually every published study about physicians and nutrition counseling showed that primary care physicians … were not delivering nutrition services to their patients.” Another study recorded thousands of patient visits to more than 150 physicians and measured how much nutrition advice was offered. It could not have been very much; the average time per visit was less than 10 seconds!
I believe all of us need to become more responsible for managing our physical and mental health – hence the name of this column, Health Yourself. Educating yourself about the role nutrition and physical activity play in lifestyle management is top of the list.
Become a self-advocate. Ask your health professional about his/her nutrition and lifestyle management training and check for advanced continuing-education credentials. Don’t be afraid to ask for referrals for health professionals who are qualified to provide nutrition counseling, advice, or evaluation of your current status.
One encouraging trend is that medical professionals are beginning to integrate patient nutrition/lifestyle management into their practices. Some medical practices now include a board-certified dietitian/nutritionist; others include experts educated and trained in lifestyle management.
