Demographics and nutrition-related patient care encounters: a survey of physician assistants in Nebraska.

Purpose: To collect information regarding demographics, nutrition-related patient care encounters, and comfort levels in addressing nutrition-related problems in a population of physician assistants (PA) currently practicing in Nebraska.

Methods: A survey was developed by faculty members in the Medical Nutrition Education and Physician Assistant Education programs, School of Allied Health Professions, College of Medicine, University of Nebraska Medical Center. Data were analyzed using descriptive statistics and Fisher's exact test.

Dietary intake data collection: challenges and limitations.

The purpose of this paper is to succinctly review the origin of US dietary surveys, the challenges and limitations of obtaining dietary intake data, the National Nutrition Monitoring and Related Research Act of 1990, the integrated US federal food survey, and the development of the US Department of Agriculture's (USDA) automated multiple-pass method. The USDA has monitored the food consumption patterns of Americans since the late 1890 s. In 2002, the US Department of Health and Human Services and the USDA integrated their data collection efforts, with data now collected on a continuous basis.

Popcorn consumption and dietary and physiological parameters of US children and adults: analysis of the National Health and Nutrition Examination Survey (NHANES) 1999-2002 dietary survey data.

Popcorn is a whole-grain food/snack that is included among foods recommended in the 2005 Dietary Guidelines for Americans and MyPyramid to increase whole-grain consumption. The purpose of the present study was to use 1999-2002 National Health and Nutrition Examination Survey 24-hour dietary recall data to determine the average popcorn intake among Americans, and whether popcorn consumers exhibited different dietary intake patterns or physiological biomarkers of cardiovascular disease compared with popcorn non-consumers. Mean intake among consumers of popcorn was 38.

Dehydration and cognitive performance.

Human neuropsychology investigates brain-behavior relationships, using objective tools (neurological tests) to tie the biological and behavior aspects together. The use of neuropsychological assessment tools in assessing potential effects of dehydration is a natural progression of the scientific pursuit to understand the physical and mental ramifications of dehydration. It has long been known that dehydration negatively affects physical performance.

Hydration: issues for the 21st century.

Historically, hydration research reflected critical issues of the day. War, illness, surviving a shipwreck or time in the dessert, supplying fall-out shelters, and space exploration drove hydration research in the first half of the 20th century. The fitness revolution of the 1970s spurred research on dehydration in physically active people and athletes.

The effect on hydration of two diets, one with and one without plain water.

Objective: To measure the effect on hydration of two regimens, one that included drinking water as part of the dietary beverages and one that did not.

Methods: In healthy, sedentary subjects, two different diets were evaluated for their effect on hydration. Trial A provided plain water to drink as part of the beverages served.
