To realize the health benefits associated with peanut consumption, it is important that they remain acceptable with regular intake. Peanuts are marketed with various flavorings so that consumers will not become fatigued by frequent consumption of any single flavor. This study sought to determine whether liking of peanuts or compliance to a peanut f...
Background:
Chronic peanut consumption is associated with health benefits. To encourage consumption, peanuts are marketed with various flavorings, but questions have been raised as to whether seasonings offset the benefits of peanuts alone.
Objective:
This study sought to determine whether flavorings on peanuts affect health benefits over 12 wk....
Consumption of spicy foods containing capsaicin, the major pungent principle in hot peppers, reportedly promotes negative energy balance. However, many individuals abstain from spicy foods due to the sensory burn and pain elicited by the capsaicin molecule. A potential alternative for nonusers of spicy foods who wish to exploit this energy balance...
Some individuals savor spicy foods, while others avoid them. Reasons underlying this range of hedonic responses are unknown. The purpose of this study was to explore the basis for individual differences in preference for spicy foods. Regular spicy food users (n=13) and non-users (n=12) were characterized for selected sensory, physiological, persona...
Previous studies suggest consumption of red pepper (RP) promotes negative energy balance. However, the RP dose provided in these studies (up to 10 g/meal) usually exceeded the amount preferred by the general population in the United States (mean=~1 g/meal). The objective of this study was to evaluate the effects of hedonically acceptable RP doses s...
Background:
Obesity is a growing epidemic among university students, and the high levels of stress reported by this population could contribute to this issue. Singular relationships between perceived stress; engagement in restrained, uncontrolled, and emotional eating; sleep; dietary risk; and body mass index (BMI) have been reported in the curren...
Background:
The prevalence of mental health concerns among university students in the United States (U.S.) continues to increase, while current treatments, including medication and counseling, present shortcomings. Higher dairy and calcium intakes are associated with protective effects on mental health; however, previous studies have focused on in...
Body composition of collegiate swimmers has been extensively studied; however, there are limited reports of body composition among Masters swimmers. This study compared the accuracy of air displacement plethysmography (ADP) and bioelectrical impedance (BIA) to the gold standard method of underwater weighing (UWW) in Masters level swimmers. The rela...
Objective: This study explored how COVID-related mental health and well-being varied between undergraduate and graduate students. Relationships with physical health behaviors were also examined. Participants: Undergraduate (n = 897) and graduate (n = 314) students were recruited from three US universities between mid-April and late-May 2020. Method...

Higher financial stress (FS) is associated with undesirable dietary behaviors. However, the relationships are not well characterized among higher education students, and investigations into why these relationships exist are lacking. As FS influences sleep while sleep influences dietary behaviors, sleep may serve as a mediator in these re...
The coronavirus disease 2019 (COVID-19) pandemic worsened financial stress for higher education students in the U.S. Financial stress is associated with poor dietary behaviors; however, factors that might influence this relationship are not well characterized. The present cross-sectional study investigated the associations between financial stress...
Background:
The coronavirus disease 2019 (COVID-19) pandemic has increased the already high levels of stress that higher education students experience. Stress influences health behaviors, including those related to dietary behaviors, alcohol, and sleep; yet the effects of stress can be mitigated by resilience. To date, past research studying the c...
Health behaviors of higher education students can be negatively influenced by stressful events. The global COVID-19 pandemic presents a unique opportunity to characterize and compare health behaviors across multiple countries and to examine how these behaviors are shaped by the pandemic experience. Undergraduate and graduate students enrolled in un...
Perceived stress affects emotional eating and food choices. However, the extent to which stress associates with food choice motives is not completely understood. This study assessed whether emotional eating mediates the associations between perceived stress levels and food choice motives (i.e., health, mood, convenience, natural content, price, sen...
High levels of perceived stress and anxiety among university students are a global concern and are known to negatively influence sleep. However, few studies have explored how stress response styles, like psychological resilience and rumination, might alter these relationships. Using validated tools, perceived stress, anxiety, stress response styles...
While the college years present an ideal time for chronic disease prevention, students often do not seek services or perceive themselves to be at health risk. Researchers at Bowling Green State University have been exploring the health patterns of first-year university students for several years, initially as a health-based research study (August 2...
For university students, alterations in sleep and diet quality are common, and the propensity for weight gain is well established. The role of sleep duration during periods of rapid weight gain is understudied. This study explored the relationships between sleep duration, diet patterns, and body composition in first-year university students. Data c...
This study compared body composition measurements in lean female athletes. The primary objective was to compare the accuracy of percent body fat (%BF) determined by bioelectrical impedance analysis (BIA), air-displacement plethysmography (ADP), and underwater weighing (UWW) in female Division I cheerleaders (n = 10 bases, 6 back-spots, and 12 flyer...
Studies demonstrate that first-year university students are at high risk for weight gain. These reports typically rely on self-selected participants. The purpose of this study was to explore if students who chose to participate in a health-based research study had more desirable health measures and behaviors than students who completed health asses...
The Army Physical Fitness Test (APFT), including timed push-ups, sit-ups, and run, assesses physical performance for the Army. Percent body fat is estimated using height and circumference measurements. The objectives of the study were to (a) compare the accuracy of height and circumference measurements to other, more accepted, body fat assessment m...
This study compared student impressions of a text-rich contractual syllabus to a graphic-rich engaging syllabus. Students enrolled in sections of an undergraduate introductory nutrition course viewed either a contractual or engaging syllabus and completed a survey regarding their perceptions of the course and instructor. Students perceived both typ...
A substantial proportion of the population does not achieve the recommended amount of sleep. Previous work demonstrates that sleep alterations perturb energy balance by disrupting appetite hormones, increasing energy intake, and decreasing physical activity. This study explored the influence of sleep duration on taste perception as well as effects...
Most investigations concerning the validity of self-reported anthropometrics focus on weight, height, and body mass index. This study extends those investigations by exploring the impact of self-reporting bias on the disease risk indicators of waist circumference and body fat percentage. Female college freshmen (n=128) self-reported weight and heig...
Application of historical knowledge and beliefs about plant-based health remedies has been limited in Western nations. However, with increased awareness of, and interest in, alternative health management techniques has come a growing openness to their potential efficacy for numerous conditions. This chapter focuses on the effects of single pungent...
While it is well documented that college freshmen gain weight, there is a dearth of studies examining critical time periods for this weight change. Freshmen living on campus (n=103; 21M, 82F) visited the laboratory in August/September, November, January, February/March, and April/May. Measurements at each visit included: weight, waist circumference...
Background
The general population is not compliant with national dietary recommendations for promoting health and reducing chronic disease risk. While rising obesity rates suggest that the majority of the population is overconsuming, many individuals affected with either acute or chronic diseases struggle to maintain adequate dietary intake and are...
Introduction
Capsaicin, the major pungent component of hot peppers, promotes negative energy balance; however, many individuals avoid capsaicin-containing foods due to pungency. Capsiate, a capsaicin analog found in CH-19 sweet peppers, is a non-pungent alternative that promotes negative energy balance when consumed as an encapsulated supplement. N...
The purpose of this was study to explore the prevalence of health risk indicators in college students upon commencement of freshman year. Within three weeks of arriving on campus, freshmen (n=20 M, 68 F; 18±0.4y) underwent measurement of height, weight, body mass index (BMI), waist circumference (WC), blood pressure (BP), and body composition (BF%)...
The visual analog scale (VAS) and the general labeled magnitude scale (gLMS) are common response formats for assessing chemosensory sensation. The gLMS is recommended when comparing sensations between individuals whose perceptual experiences vary in a manner that may not be accurately captured on the VAS. This may occur when one group has a wider r...
While some previous literature indicates that red pepper (RP) consumption confers weight management benefits, findings have been contradictory. It was posited that these inconsistencies related to poor control over characteristics of the subject population, such as failure to stratify results by habitual use of spicy foods. Consequently, this disse...
Some studies suggest that capsaicin diminishes orexigenic sensations, but reports are conflicting. One methodological issue potentially accounting for inconsistencies may be differing characteristics of study populations. The purpose of this trial was to contrast responsiveness to capsaicin’s appetitive effects in regular spicy food users (n=13) an...
Previous studies suggest consumption of red pepper (RP) promotes negative energy balance. However, the RP dose provided in these studies (e.g., 10 g/meal) generally exceeded the amount preferred by the population (~1 g/meal). The objective of this study was to evaluate the effects of realistic and preferred RP doses served at a single meal in healt...
A cross-sectional study of 77 patients infected with human immunodeficiency virus (HIV) in Khon Kaen, Thailand examined association of nutritional status with active opportunistic infections (AOIs)/HIV status and assessed degree of correlation between bioelectrical impedance analysis (BIA) and anthropometry. Many patients (41.3%) were malnourished...
