Nutrition Education in Medical School

Recent statistics show that more than two-thirds of Americans are considered to be overweight or obese. With diabetes and obesity on the rise, in addition to spikes in other lifestyle-related diseases, it has become critical to highlight the necessity of self-care and healthy living habits. Yet while physicians are generally considered to be reliable sources regarding nutrition, more than 50% of graduating medical students continue to rate their knowledge as ‘inadequate,’ and only one in eight patients receives counseling from their doctors on dietary health benefits.

A study designed to quantify the required number of hours of nutrition education at U.S. medical schools, in addition to an investigation regarding the types of courses offered, reaffirmed the supposition that medical students receive an inadequate amount of nutrition education. Only 27% of surveyed schools required a course dedicated to nutrition; on average, U.S. medical schools only offer 19.6 hours of nutrition education—across four years of medical school.

A 2016 study in the International Journal of Adolescent Medicine and Health assessed the basic nutritional knowledge of fourth-year medical and osteopathic school graduates entering a pediatric residency program. On average, the incoming interns were only able to answer 52% of the 18 questions correctly. Marion Nestle, a renowned professor of nutrition, food studies, and public health at New York University, chalks much of this up to the fact that there is a primary focus on treating–rather than preventing–diseases.

Throughout the past several decades, there has been a push towards improving the medical nutrition education that students receive. With suboptimal knowledge about dietary habits, future physicians are selling both themselves and their patients very short. It is imperative to equip health practitioners with the necessary tools and information that they can utilize in their practices, ultimately addressing the root causes of real, pervasive problems.

How to Save Your Brain

A report published by the National Academies of Sciences, Engineering and Medicine (NASEM) cites promising evidence indicating that active cognitive training, blood pressure management, and physical activity may collectively help stave off age-related cognitive decline and dementia.

In 2015, the Alzheimer’s Association released similar findings that identified two critical activities that could minimize the risk of cognitive decline: increasing physical activity, and improving cardiovascular health. Dan G. Blazer, a member of the NASEM committee that conducted the study and the J.P. Gibbons Professor of Psychiatry Emeritus at Duke University Medical Center, states: “What is good for the heart is good for the brain. Therefore, exercise and controlling high blood pressure are good for the brain.” While controlling blood pressure is good preventive practice to combat heart disease, it may also reduce memory less and dementia—likely because high blood pressure damages delicate blood vessels in the brain.

In terms of diet, a study released by Temple University found that extra-virgin olive helped fend off Alzheimer’s in mice. The mice fed a diet rich in extra-virgin olive oil showed better learning and memory skills than those who did not receive the diet. While the evidence surrounding diet is not as conclusive and plentiful as the research regarding exercise, the panel singled out diets that emphasized whole grains, fruits and vegetables, low-fat dairy, and lower levels of salts.

Cognitive training has been receiving more attention recently, referring to tools and tactics engineered to improve reasoning, problem-solving, memory retention, and processing speed. In a randomized control trial reviewed by the committee titled “Advanced Cognitive Training for Independent and Vital Elderly,” participants who received cognitive training in processing speed and reasoning deduction demonstrated less decline than those who did not, over a time span of ten years.

More than 5 million Americans have been diagnosed with Alzheimer’s, the most common form of dementia, and the number is only expected to increase as the population ages. Statistics show that by 2050, numbers could reach up to 16 million. There is no cure, and few effective treatments. Yet the evidence suggests that these lifestyle changes may actively reduce risk, or at least delay the onset of dementia. Dr. Richard Hodes, director of the National Institute on Aging, advised people to “Try and avoid the tendency to sit down, watch television for endless hours at night. Get out there, do something.”

The Power of Ginger

A new review published in the Annals of the New York Academy of Sciences assesses findings of 60 studies surrounding ginger—as a supplement, or ingredient in food and drink. Although experts have not yet determined a specific dosage for preventive purposes, the review concludes that ginger consumption is medically sound and helpful.

The studies “have built a consensus that ginger and its major constituents exert beneficial effects against obesity, diabetes, cardiovascular diseases, and related disorders,” wrote authors from China Agricultural University. The researchers focused their studies on the different aspects of metabolic syndrome—a combination of three or more risk factors for type 2 diabetes and heart disease. Metabolic syndrome now affects almost a quarter of the world’s population: a growing health problem that has reached reportedly pandemic proportions.

Scientists have researched potential strategies in order to both prevent and treat metabolic syndrome, specifically non-pharmaceutical options. As ginger has a long history of treating a variety of ailments and illnesses, due to its phytochemicals and antioxidants, the general consensus is that there are several mechanisms behind ginger’s ‘superfood powers.’ The paper details the ways in which the spice plays a significant role in fat burning, carbohydrate digestion, and insulin secretion; ginger has also demonstrated an ability to inhibit oxidative stress—a form of cellular aging—in addition to anti-inflammatory properties.

During a study in which ginger was fed to rats, ginger significantly reduced body weight and systemic inflammation, while simultaneously lowering cholesterol and blood sugar. The accumulation of studies suggest that consuming ginger can also enhance calorie burn and reduce feelings of hunger, likely associated with weight loss in overweight adults. Associate professor of nutritional medicine at Columbia University Marie-Pierre St-Onge states that while the field is still developing in terms of assessing the impact of various spices, on humans, “The research is very promising.”
