Total Usual Intake of Shortfall Nutrients Varies With Poverty Among US Adults.

OBJECTIVE: To examine shortfall nutrient intakes (ie, calcium, folate, potassium, magnesium, and vitamins A, C, D, and E) by poverty-to-income ratio (PIR). DESIGN: National Health and Nutrition Examination Survey 2011-2012, a nationally representative, cross-sectional survey. PARTICIPANTS: US adults with complete data on poverty status and diet were included (n = 4,524). ANALYSIS: The National Cancer Institute method was used to estimate total usual micronutrient intakes from foods, beverages, medications, and dietary supplements reported on 2 24-hour dietary recalls using measurement error correction. MAIN OUTCOME MEASURES: Calcium, folate, potassium, magnesium, and vitamins A, C, D, and E across 3 PIR categories: <130%, 130% to 350%, and ≥350%. RESULTS: Mean intakes of folate, vitamin C, and vitamin D were significantly greater in men, and magnesium in women, across all PIR categories. Except for calcium in men and vitamin C in women, the highest PIR category had significantly higher mean total usual intakes of all remaining shortfall micronutrients. Importantly, men and women in the highest PIR category (≥350%) were significantly less likely to have intakes below the Estimated Average Requirement across all micronutrients compared with those in the lower PIR categories. CONCLUSIONS AND IMPLICATIONS: Even with dietary supplements, large proportions of US adults have micronutrient intakes below the Estimated Average Requirement. Adults at the highest adjusted income have higher micronutrient intakes and lower risk of inadequacy than those with lower incomes.

Nutrition competencies in health professionals' education and training: a new paradigm.

Most health care professionals are not adequately trained to address diet and nutrition-related issues with their patients, thus missing important opportunities to ameliorate chronic diseases and improve outcomes in acute illness. In this symposium, the speakers reviewed the status of nutrition education for health care professionals in the United States, United Kingdom, and Australia. Nutrition education is not required for educating and training physicians in many countries. Nutrition education for the spectrum of health care professionals is uncoordinated, which runs contrary to the current theme of interprofessional education. The central role of competencies in guiding medical education was emphasized and the urgent need to establish competencies in nutrition-related patient care was presented. The importance of additional strategies to improve nutrition education of health care professionals was highlighted. Public health legislation such as the Patient Protection and Affordable Care Act recognizes the role of nutrition, however, to capitalize on this increasing momentum, health care professionals must be trained to deliver needed services. Thus, there is a pressing need to garner support from stakeholders to achieve this goal. Promoting a research agenda that provides outcome-based evidence on individual and public health levels is needed to improve and sustain effective interprofessional nutrition education.

The need to advance nutrition education in the training of health care professionals and recommended research to evaluate implementation and effectiveness.

Nutrition is a recognized determinant in 3 (ie, diseases of the heart, malignant neoplasms, cerebrovascular diseases) of the top 4 leading causes of death in the United States. However, many health care providers are not adequately trained to address lifestyle recommendations that include nutrition and physical activity behaviors in a manner that could mitigate disease development or progression. This contributes to a compelling need to markedly improve nutrition education for health care professionals and to establish curricular standards and requisite nutrition and physical activity competencies in the education, training, and continuing education for health care professionals. This article reports the present status of nutrition and physical activity education for health care professionals, evaluates the current pedagogic models, and underscores the urgent need to realign and synergize these models to reflect evidence-based and outcomes-focused education.

Nutrition education in medical school: a time of opportunity.

Undergraduate medical education has undergone significant changes in development of new curricula, new pedagogies, and new forms of assessment since the Nutrition Academic Award was launched more than a decade ago. With an emphasis on a competency-based curriculum, integrated learning, longitudinal clinical experiences, and implementation of new technology, nutrition educators have an opportunity to introduce nutrition and diet behavior-related learning experiences across the continuum of medical education. Innovative learning opportunities include bridging personal health and nutrition to community, public, and global health concerns; integrating nutrition into lifestyle medicine training; and using nutrition as a model for teaching the continuum of care and promoting interprofessional team-based care. Faculty development and identification of leaders to serve as champions for nutrition education continue to be a challenge.

Nutrition and physical activity in health promotion and disease prevention: potential role for the dental profession.

Nutrition contributes to many of the leading causes of death in the United States, yet less than one-third of dental students feel competent to discuss the relationship of nutrition and systemic disease with their patients. The American Dental Association policy statements acknowledge a need for health professionals and organizations to provide continuing education to professionals and counseling to patients to combat the growing problems of overweight and obesity. Dentists can play a major role in educating patients to adopt a healthier lifestyle, including nutrition and physical activity recommendations. An understanding of the complexity of behavior change may enhance the dentist's ability to assist their patients in making desired changes.

Micronutrient requirements of physically active women: what can we learn from iron?

The health benefits of physical activity are well established and there is increasing recognition of the importance of fitness as a key modulator of chronic disease. The impact of physical activity on micronutrient requirements is a topic of tremendous interest to the lay public, but the interest is in sharp contrast to data from well-designed studies. Research in this area is poorly controlled for nutritional status of the participants, standardized exercise protocols, markers and cutoff points for measurement of micronutrient status, and variability in subject characteristics. The micronutrient status of women in the general population is of concern, but it is not clear that physical activity increases the requirement of most micronutrients. When dietary intake is adequate, the results of most studies are either equivocal or show no benefit to performance of supplementation. In the few instances where exercise does appear to increase an individual's requirement, the increase can be obtained within the additional calories required for energy balance. In the absence of consistent data, micronutrient supplementation is often indiscriminate without regard to nutrient status. Because iron is such a key nutrient for physical activity, and the status in women is often compromised, it serves as a useful example of how current research limits the ability to make recommendations regarding the impact of exercise on micronutrients requirements in women. With the recent recognition of the importance of physical activity to the prevention and treatment of chronic diseases through the life span, more attention should be focused on the impact of exercise on micronutrient requirements, especially in the context of weight loss regimens.
