Randomly assigned messages were tailored to resonate with either monitors or blunters and delivered at baseline, 1 week, 2 months, and 3 months later. Surveys were conducted at baseline and 2 and 4 months later.

Participants

531 callers to a cancer information hotline who did not meet the 5 A Day guideline.

Intervention

A brief telephone-delivered …

Alteration Of The Gastrointestinal Microbiota Of Mice By Edible Blue-Green Algae, H. E. Rasmussen, I. Martínez, J. Y. Lee, J. Walter

Department of Nutrition and Health Sciences: Faculty Publications

Aims: To characterize the effect of edible blue-green algae (cyanobacteria) on the gastrointestinal microbiota of mice. Methods and Results: C57BL⁄6J mice were fed a diet supplemented with 0% or 5% dried Nostoc commune, Spirulina platensis, or Aphanizominon flos-aquae (w⁄w) for 4 weeks. Molecular fingerprinting of the colonic microbiota using denaturing gradient gel electrophoresis revealed that administration of N. commune induced major alterations in colonic microbiota composition, while administration of S. platensis or A. flos-aquae had a more subtle impact. Community profile analysis revealed that administration of N. commune did not reduce microbial diversity indices of the colonic microbiota. …

Aerobic Fitness Does Not Modulate Protein Metabolism In Response To Increased Exercise: A Controlled Trial, Tracey J. Smith, Matthew A. Pikosky, Ann Grediagin, Carmen Castaneda-Sceppa, Lauri O. Byerley, Ellen L. Glickman, Andrew J. Young

School of Medicine Faculty Publications

BACKGROUND: A sudden increase in exercise and energy expenditure is associated with an increase in protein turnover and nitrogen excretion. This study examined how a sudden increase in exercise-induced energy expenditure affected whole body protein metabolism and nitrogen balance in people of differing levels of aerobic fitness. We hypothesized that alterations in whole-body protein turnover would be attenuated, and nitrogen balance would be preserved, in individual with higher levels of aerobic fitness. METHODS: Eleven men, categorized as either having a lower (LOW-FIT; n = 5) or higher (FIT; n = 6) aerobic fitness level, completed a 4-d baseline period (BL) …

Measuring Patient Satisfaction After Providing A Choice Of Nourishment Options Between Meals In A Long-Term Care Setting., Samantha Hutson

Electronic Theses and Dissertations

The purpose of this study was to determine whether providing residents of the James H. Quillen Veterans Affairs Medical Center Community Living Center with a choice of nourishment options between meals would improve their satisfaction with the nourishment administration process. As opposed to being given the same nourishment item each day, residents were offered choices from a nourishment cart based upon their diet order. Sixteen residents completed the pre-survey, participated in the revised nourishment cart system for a 3-week period, and completed the postsurvey. Level of satisfaction was determined by analyzing the responses given by the residents on the pre- …

Correlates Of Soy Food Consumption In Adventist Health Study-2, Yen Ang

Loma Linda University Electronic Theses, Dissertations & Projects

Much has been discussed about the health benefits and risks of soy consumption but very little is known about who the consumers are. Most of what is known has been observed mainly in Asian populations who consume high levels of soy. Very little is known about soy food intake in the western population who typically has low consumption level. The Seventh-Day Adventist cohort in North America is the only population known in the West with soy food intake that is comparable to the Asian population living in the East.

Soy consumers in a population known for its healthier lifestyle and …

Effects Of Β-Alanine Supplementation And High-Intensity Interval Training On Endurance Performance And Body Composition In Men; A Double-Blind Trial, Abbie E. Smith, Ashley A. Walter, Jennifer L. Graef, Kristina L. Kendall, Jordan R. Moon, Christopher M. Lockwood, David H. Fukuda, Travis W. Beck, Joel T. Cramer, Jeffrey R. Stout

Department of Nutrition and Health Sciences: Faculty Publications

Background: Intermittent bouts of high-intensity exercise result in diminished stores of energy substrates, followed by an accumulation of metabolites, promoting chronic physiological adaptations. In addition, β-alanine has been accepted has an effective physiological hydrogen ion (H⁺) buffer. Concurrent high-intensity interval training (HIIT) and β-alanine supplementation may result in greater adaptations than HIIT alone. The purpose of the current study was to evaluate the effects of combining β-alanine supplementation with high-intensity interval training (HIIT) on endurance performance and aerobic metabolism in recreationally active college-aged men.

Methods: Forty-six men (Age: 22.2 ± 2.7 yrs; Ht: 178.1 ± 7.4 cm; Wt: …
