Rana ZH, Frankenfeld CL, Kennedy EJ, Bertoldo J, De Jonge L, Cheskin LJ. Why don't college freshmen meet the US dietary guidelines for added sugar, refined grains, sodium, and saturated fat? JOURNAL OF AMERICAN COLLEGE HEALTH : J OF ACH 2024; 72:142-152. [PMID: 35080478 DOI: 10.1080/07448481.2021.2024213] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/13/2021] [Revised: 12/05/2021] [Accepted: 12/26/2021] [Indexed: 06/14/2023]
Abstract
OBJECTIVE The objective of the study was to evaluate how well college students meet U.S. dietary guidelines by examining the mean intakes of nutrients to limit (sodium, sugar, refined grains, and saturated fat), and what factors lead to exceeding the dietary recommendations. PARTICIPANTS Participants were first-year undergraduate students (N = 269). METHODS Diet was assessed using a DHQ-III and estimated with food source composition tables. Multivariable logistic regression analysis was used to model variables associated with exceeding the recommendations. One-sample t-tests were performed to compare the cohort with national intakes. RESULTS One-third met added sugar guidelines; only 4% met daily refined grains requirements, Fewer than half met saturated fat guidelines, and slightly over half met recommended sodium guidelines. Level of physical activity, race/ethnicity, and living on campus were the important predictors for exceeding recommended intakes. CONCLUSIONS Most students do not adhere to the U.S. dietary guidelines for nutrients to limit.

Abstract
Studies show that regularly consuming whole grains reduce the risk of obesity and a wide range of chronic diseases. Despite this, studies reveal that students are consuming fewer whole grains. In the present study, we aimed to investigate the barriers to the consumption of whole grains among Iranian students. This cross-sectional study examined students at Fasa, Iran in 2020–2021. The online questionnaires were completed by students after receiving informed consent. Statistical analysis was performed using SPSS 26 and Chi-square, t-test, and logistic regression (P > 0.05). The current study involved 1890 students (1287 (68.1%) girls and 603 (31.9%) boys). Despite the preference for white flour bread among 53.8% of all students, 77.4% ate other whole-grain products, and 75.2% consumed all products at least once a week. Additionally, barriers such as access issues (70.5%), family supply issues (91.8%), lack appeal (72.8%), non-consumption by classmates (96.2%), and high prices in recent years (43.9%) were identified as obstacles to whole grain consumption. Furthermore, white bread eating students had significantly lower appetite levels and tended to eat fast food more often than those who ate whole grains (P < 0.05). We found that slightly more than half of the participants preferred to eat bread prepared with refined flour. Several other factors, including lack of access, lack of attractiveness, product price, parents not purchasing whole-grain products, students not paying attention to nutrition labels, peers’ effect, and eating with friends instead of family, also contribute to students avoiding whole-grain products.

A Pilot Study on RTE Food Purchasing and Food-Related Behaviors of College Students in an Urbanized Area. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19063322. [PMID: 35329009 PMCID: PMC8953631 DOI: 10.3390/ijerph19063322] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/23/2021] [Revised: 01/27/2022] [Accepted: 03/02/2022] [Indexed: 11/16/2022]
Abstract
Ready-to-eat (RTE) food is widely used, and younger age groups are increasingly purchasing these items. This study investigated college students' consumption of RTE foods and food-related behaviors such as dietary habits, lifestyle, eating out behaviors, and demographic characteristics. We used quantitative methods to gather data. A questionnaire was developed from previous studies and was self-administered to college students in Daejeon, Republic of Korea. Descriptive analysis, ANOVA, and Chi-square tests were conducted to investigate RTE food consumption behaviors and food-related lifestyle factors. A total of 285 data points was entered for analysis. This study found that BMI and gender significantly impacted dietary habits. Residence type and gender showed significant effects on dining out partners. Furthermore, results showed the time of snack consumption and RTE food were similar, suggesting that a snack was replacing college students' meals or that they might consider RTE food as a snack, or vice versa. A nutrition intervention program for college students should be implemented to encourage a healthy diet.

Abstract
Sexual and gender minority college students are underrepresented in nutrition research and may face unique challenges related to eating which impact their overall diet quality. We assessed the differences in eating competence and dietary intake between sexual and gender minority (SGM) and cisgender heterosexual (CH) college students. Participants (n = 2645) reported sexual orientation, gender identity and completed the Eating Competence Satter Inventory (ecSI 2.0™ through an online questionnaire. Three-day food records examined dietary intake. Intake was compared to recommendations for nutrients of public health concern. Chi-square and ANCOVA examined differences between eating competence and dietary intake. There were no differences in total ecSI 2.0™ scores. Subscale scores for Eating Attitudes and Contextual Skills were significantly higher in CH vs. SGM students (13.4 ± 0.1 vs. 12.4 ± 0.4 p = 0.01 and 10.7 ± 0.1 vs. 9.9 ± 0.3, p = 0.01, respectively). Most students (40.8%) met one nutrient recommendation. The proportion of students meeting nutrient recommendations were similar for SGM and CH. SGM populations may struggle with attitudes and eating behaviors. Dietary intake of SGM and CH students were similarly inadequate when compared to recommendations.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18063173. [PMID: 33808575 PMCID: PMC8003352 DOI: 10.3390/ijerph18063173] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Revised: 03/08/2021] [Accepted: 03/17/2021] [Indexed: 12/24/2022]
Abstract
College students’ lifestyle and eating habits strongly affect their health. Among many healthy eating behaviors, including whole grain food in the diet is known as providing health benefits such as maintaining a steady blood sugar, lower cholesterol, and since it is rich in fiber and minerals, it is essential for the well-being. However, consumers’ intakes of whole grain products remain below recommendation, including college students. This study aims to evaluate determinant factors contributing to college students’ willingness to include whole grain pasta in their diets. A sample of 499 students enrolled in a US college participated in this study. Most students perceived whole grain pasta as healthy and filling and somewhat tasty. Availability and price were not barriers for consumption. Logistic regression results suggested that factors affecting students’ willingness to consume whole grain pasta in the future were the desire to eat, cognitive and affective attitudes, perception of whole grain pasta, as well as having already chosen pasta thanks to its availability at the dining. Two student segments were identified according to their healthy eating perception: Uninvolved and Health-conscious. Cognitive attitudes such as beneficial and essential had positive effects on consumption in both segments, suggesting that information provision covering specific health/nutritional benefits of whole grains for students is crucial.

Kissock KR, Neale EP, Beck EJ. Whole Grain Food Definition Effects on Determining Associations of Whole Grain Intake and Body Weight Changes: A Systematic Review. Adv Nutr 2020; 12:693-707. [PMID: 33070194 PMCID: PMC8166549 DOI: 10.1093/advances/nmaa122] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2020] [Revised: 07/21/2020] [Accepted: 09/04/2020] [Indexed: 02/06/2023] Open
Abstract
Within epidemiological and intervention studies, whole grain consumption has generally shown positive associations with reductions in markers of overweight and obesity. However, studies use varied methods of determining whole grain intake, including different definitions of a whole grain food, which may explain varied results. This systematic review aimed to identify how different methods of reporting and calculating whole grain intake, including whole grain food definitions, affect reported associations between whole grain intake and body weight measures in adults. Systematic searching of PubMed, Scopus, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Central Register for Controlled Trials (CENTRAL), and MEDLINE (all years to 11 June, 2020) identified eligible studies. Cohort and cross-sectional studies assessing whole grain intake and body weight measures in adults were included. Studies that did not specify methods used to calculate whole grain intake were excluded. Twenty-one cross-sectional studies (from 24 articles) and 9 prospective cohort studies (from 7 articles) were included in the review. Many cross-sectional studies showed whole grain intake was, to some degree, significantly associated with body weight measures, whereas associations varied greatly among cohort studies. Studies calculating whole grain intake using total grams of intake, USDA databases, or ≥25% whole grain in combination with listing specific foods, showed consistent beneficial effects of increasing whole grain intake on body weight. Studies with general lists of foods included as "whole grain foods" or lower cut-offs for whole grain content were inconsistent. The majority of studies reported whole grain intake as servings/day or grams whole grain/day. This review suggests that an association between whole grain and body weight measures remains likely, although precise associations are difficult to determine due to heterogeneity in methodologies and an inability to formally compare studies. Moving forward, application of a standardized methodology to calculate whole grain intake is essential.

Abstract
One-third of all food produced for human consumption is wasted producing landfill accumulation and greenhouse gas emissions. Brewers' Spent Grains (BSGs) are the leftover grains from beer production, and each year approximately 30 million tons of BSG is generated globally by the brewing industry. Reclaiming BSG as a potential human food source is an opportunity for reducing food waste in the food supply chain. Six focus groups were conducted using 37 college students to determine their consumption of whole grains, perceptions of whole grains versus refined grains, and interest in or barriers related to consuming and purchasing foods made with BSG. Focus groups were transcribed verbatim and analyzed using constant comparative analysis to identify themes and discover relationships among the study aims. Thirteen themes emerged from focus group discussions with Concept of Health, Sensory, and Experience with BSG representing the top three discussed. Participants believed whole grains are healthier and contain more nutrients than refined grains. Most participants enjoyed the BSG foods provided; however, some noted a darker appearance and lingering fiber particles or aftertaste. Findings indicate participants who are hereditary whole grain consumers are acculturated to whole grain sensory attributes and nutritional benefits and would be more receptive to consuming BSG foods in future studies. We concluded most focus group participants were open to tasting BSG foods, but hereditary whole grain consumers should be the target consumer audience, and educating consumers on sensory attributes, potential health benefits, and environmental benefits is necessary to overcome the barriers associated with BSG.

Abstract
BACKGROUND Unhealthy dietary patterns are associated with metabolic changes and increased risk of non-communicable diseases (NCDs), but these associations have not been investigated in representative populations of university undergraduates in low-to-middle income countries (LMICs). METHODS This study was conducted in the three universities in Lagos State, Nigeria to assess the dietary pattern and metabolic risk factors of NCDs among university undergraduate population. Multistage sampling technique was used to select 506 undergraduates from the universities. Pre-tested questionnaire was used to obtain data on socio-demographic characteristics and dietary patterns. Body mass index and metabolic risk factors (abdominal obesity, dyslipidemias, high blood pressure and hyperglycemia) were assessed following standard procedures. SPSS (version 20) was used for data entry and analysis. Association between variables was determined using chi-square and Fisher's exact tests. RESULTS The mean age was 20.3 ± 3.5 years; 54.7% of them were female. More than one third (37.6%) had no consistent source of income or received less than N10, 000 ($31.7) per month. Less than one third (31.0%) ate three daily meals, 23.0% ate breakfast regularly, and only 2% consumed the recommended daily amount of fruits and vegetables. Almost half (44.0%) ate pastry snacks daily. Refined rice was the commonest cereal (28.2%) consumed while meat was more commonly consumed daily (32.0%) than milk (14.0%) and fish (10.0%). Twenty-nine (29.0%) and 6.2% of the population daily consumed carbonated soft drinks and alcohol, respectively. Prevalence of abdominal obesity (based on waist circumference) was 5% (1.3% in males and 8.4% in females), dyslipidemias (57.3%), pre-hypertension (8.2%), hypertension (2.8%), and pre-diabetes (1.0%). Obesity was positively associated with consumption of alcohol (χ2 = 13.299, p < 0.001). CONCLUSION Unhealthy diets and metabolic risk factors of non-communicable diseases are prevalent in the undergraduate population studied. Well-recognized recommendations regarding adequate consumption of fruits, vegetables, fish, and whole grains should be emphasized in a targeted manner in this population. Carbonated soft drinks and alcohol consumption should be discouraged to stem a rising tide of metabolic risk factors for non-communicable diseases among undergraduate students.

Abstract
Adolescents and young adults in the United States do not consume recommended amounts of whole grains. University dining services have opportunities to inform students about whole grains and to offer foods containing blends of whole grains with refined flour to increase daily consumption of these healthful foods. An online survey of university students (n = 100) found that 70% of respondents did not know the proportion of servings of whole grains that should be eaten daily. Mini blueberry muffins containing 50, 75, and 100% white whole wheat flour were served to 50 undergraduate students who rated their liking of the muffins using a nine-point hedonic scale. Respondents liked all muffin formulations similarly for appearance, taste, texture and overall liking. After the whole grain content of each muffin was revealed, 66% of students increased their liking of the muffins containing 100% whole wheat flour. Only half of the students increased their liking for the 75% whole wheat flour muffins, and most students reported no change in liking for the muffins made with the lowest percentage of whole wheat flour. Labeling whole grain foods in university foodservice operations may increase consumption of this food group by some students. Further research with actual purchase behavior is needed.

Abstract
Observational studies consistently find an inverse relationship between whole-grain intake and weight gain. We aimed to confirm this in an open-label researcher-blinded parallel design randomised trial. A total of 179 overweight/obese women with a habitually low whole-grain intake (<16 g/day) were randomised to a weight maintenance diet with refined-grain (RG) or whole-grain (WG) foods (80 g/day) for 12 weeks after an initial weight loss program over 8 weeks. Body weight and composition was assessed at baseline, after the initial weight loss, and after the 12-week dietary intervention. During the 12-week dietary intervention phase, there were no group differences in changes in body weight and total fat mass %, whereas abdominal fat mass tended to increase more during the dietary intervention phase in the WG compared to the RG group (0.7 (SD 3.6) vs. −0.3 (SD 3.8) %; p = 0.052). Plasma alkylresorcinol concentrations, biomarkers of wholegrain wheat and rye intake, indicated poor compliance, particularly in the WG group, where >60% of participants had alkylresorcinol concentrations below 70 nmol/L, a concentration indicating low or no intake of whole-grain wheat. Further, weight regain was lower than expected in both intervention groups, further supporting a lack of compliance to the post-weight-loss diet. The rate of compliance was too low to conclude any effect of whole grain on weight maintenance, and reinforces the need to use objective measures of compliance in nutrition intervention studies.

Abstract
Purpose
The health benefits of whole grains are well established, yet intake remains below recommendations. Knowledge and familiarity with whole grains may increase short-term intake, but sensory properties can limit consumption. These factors usually are researched separately, thus, this study aims to explore the relationships among sensory liking, knowledge, attitudes and intake.
Design/methodology/approach
This cross-sectional study had 69 college students participate in four tasks: sensory liking of whole vs refined grain bread, rice, pasta and tortillas; bitter taster status; knowledge and attitudes; and intake of whole grains.
Findings
Whole wheat bread and tortillas were liked, as well as their refined grain counterparts. However, white rice and pasta were liked significantly more than the whole grain products (p < 0.05), which are less familiar to most people. Higher consumers of whole grain foods preferred those samples to the refined product for some sensory attributes (p < 0.05). Bitter taster status was not related to sensory preferences. Understanding and recognition of whole grains was low, but attitudes were generally positive. Whole grain intake was overestimated by the food frequency questionnaire because of problems with the instrument and also subjects’ lack of understanding about these foods.
Research limitations/implications
The link between preference and consumption warrants further study. The survey used to measure whole grain intake was a limitation and demonstrates the need for an accurate and efficient tool. Although knowledge about whole grains is limited, the positive attitudes expressed by participants can strategically inform outreach. If people believe that they consume more whole grains than they actually do, they may have a false sense of security. Further research with different age groups and a wider variety of foods is needed.
Practical implications
Participants overestimated their consumption of whole grain foods, indicating that consumers may think that they are meeting recommended amounts but they are actually deficient in whole grain intake; thus, improved education and promotional efforts are needed.
Originality/value
Few studies examine the inter-relationships among sensory preference, bitter taster status, knowledge, attitude and intake of whole grains.

Abstract
The transition from adolescence to adulthood is a unique period during which lifelong dietary habits are shaped. Dietary patterns (DPs) among young adults attending college have not been adequately described, and associations between DPs and indicators of disease risk are not well understood in this age group. Dietary data were collected from undergraduates participating in the Tufts Longitudinal Health Study (TLHS; 1998-2007) by Food Frequency Questionnaire (FFQ; n = 1323). DPs were derived using principal components analysis with varimax rotation. Scree plots; eigenvalues; factor loadings; and previous studies were used to determine and label the DPs retained. Cross-sectional relationships between DP scores and anthropometric measures (percent body fat (PBF) and (BMI) and lipid biomarkers (total; HDL and LDL cholesterol; and triglycerides) were assessed with multivariable regression models; adjusted for demographics; physical activity; smoking; intention to gain/lose weight; and total energy intake. Effect modification by sex was tested. Three DPs were identified: Prudent; Western; and Alcohol. Greater adherence to the Prudent DP was associated with favorable anthropometric outcomes. The Alcohol DP was associated with a favorable lipid profile. Associations between the Western DP and blood lipids differed by sex; with unfavorable impact observed only among males. Our findings add to the literature linking DPs in young adults with measurable adiposity and cardiometabolic outcomes; suggesting that improving nutrition among college students could reduce chronic disease risk.

Abstract
BACKGROUND Evidence from epidemiological studies suggests that higher whole grain intake is associated with improvements in body weight measures. Evidence from randomized controlled intervention studies is controversial. OBJECTIVE To assess the scientific evidence, using a descriptive systematic approach, related to the relationship/effects of whole grain on weight management. METHODS Medicine Medical Subject Headings (MeSH) were used to search in Medline and Scopus, dating from 1980 to July 2013. Subsequently, 2 researchers assessed independently the resulting abstracts, using hierarchically targeted selection criteria. RESULTS A moderate body of evidence from epidemiological studies consistently demonstrates that a higher intake of whole grains is associated with lower body weight, BMI, waist circumference, abdominal adiposity, and weight gain. The evidence from intervention studies is, in comparison, limited and less consistent. Current evidence fails to clearly demonstrate that whole grain intake can contribute to weight loss independent of hypocaloric diets. The lack of consistency in intervention studies may partly be explained by heterogeneity in study duration, types and amounts of whole grain foods included, population, and sample sizes. CONCLUSIONS Future epidemiological and intervention studies are needed to address the limitations observed in the current body of evidence, importantly using a consistent definition of whole grain foods, and the amount of whole grains consumed. Furthermore, studies need to be conducted on diets that potentially include single grains.

Abstract
More than one-half of young adults aged 18-24 y have at least 1 coronary heart disease (CHD) risk factor and nearly one-quarter have advanced atherosclerotic lesions. The extent of atherosclerosis is directly correlated with the number of risk factors. Unhealthy dietary choices made by this age group contribute to weight gain and dyslipidemia. Risk factor profiles in young adulthood strongly predict long-term CHD risk. Early detection is critical to identify individuals at risk and to promote lifestyle changes before disease progression occurs. Despite the presence of risk factors and pathological changes, risk assessment and disease prevention efforts are lacking in this age group. Most young adults are not screened and are unaware of their risk. This review provides pathological evidence along with current risk factor prevalence data to demonstrate the need for early detection. Eighty percent of heart disease is preventable through diet and lifestyle, and young adults are ideal targets for prevention efforts because they are in the process of establishing lifestyle habits, which track forward into adulthood. This review aims to establish the need for increased screening, risk assessment, education, and management in young adults. These essential screening efforts should include the assessment of all CHD risk factors and lifestyle habits (diet, exercise, and smoking), blood pressure, glucose, and body mass index in addition to the traditional lipid panel for effective long-term risk reduction.

Abstract
PURPOSE This study evaluated the food stores on and near postsecondary campuses varying in institutional size. DESIGN The design of the study is an environmental audit survey. SETTING Fifteen U.S. postsecondary education institutions participated in this study between 2009-2011. SUBJECTS Eighty-one stores (44% grocery, 17% campus, and 39% convenience/drug) were evaluated. MEASURES The Nutrition Environment Measures Survey for Stores was modified to evaluate food stores. Analysis. Analysis of variance with post hoc Tukey B and t-tests assessed differences between store types and by institutional size. RESULTS Grocery stores had significantly higher scores than campus/convenience stores for healthy foods (19.5 ± 3.8 vs. 2.4 ± 1.7), and for the availability (19.5 ± 3.8 vs. 2.4 ± 1.7) and quality (5.9 ± 0.5 vs. 1.8 ± 2.2) of fruits/vegetables (p < .001). Healthy foods and beverages were significantly more expensive (-0.6 ± 3.4 vs. 0.9 ± 2.0; p < .031) than their less healthful alternatives in grocery stores, but not in convenience stores. There were no differences by institutional size for grocery stores; however, smaller institutions' convenience stores had significantly lower availability and quality of fruits/vegetables and total food store environment scores. CONCLUSION A college campus provides a food environment with an array of shopping venues, most of which are not consistent with dietary recommendations for obesity prevention. The limited quality of healthy food in on-campus and convenience stores and the exacerbated deficiencies for small postsecondary institutions provide evidence to support environmental and policy initiatives to improve the quality of campus food store environments.

Abstract
PURPOSE Differences in knowledge, perceptions, and consumption of whole grains were compared between students who had taken an introductory university nutrition course and those who had not. METHODS The sample consisted of two groups: 109 students who had completed a nutrition course and 61 who had not. The two samples were drawn from second-year nursing students and students in second-year psychology courses, respectively. All students completed a 25-item questionnaire. Chi-square tests were used to identify associations between completion of a nutrition course and responses. RESULTS Nutrition education students had more knowledge of whole grain recommendations, of whole grains available in stores, and of whole grains as a factor in disease risk reduction (p<0.05). In contrast, non-nutrition education students had more knowledge of whole grain health claims, reported a greater preference for the taste of whole grains, and had a greater than mean intake of whole grain cereals (p<0.05). CONCLUSIONS This prelimary study indicates that completion of an introductory nutrition course has a greater influence on positive perceptions of whole grains than on students' consumption frequency or knowledge of whole grains. Further study may provide more information on nutrition education and whole grains.

Abstract
OBJECTIVE The present study evaluated the restaurant and dining venues on and near post-secondary campuses varying in institution size. DESIGN The Nutrition Environment Measures Survey for Restaurants (NEMS-R) was modified to evaluate restaurants as fast food, sit down and fast casual; and campus dining venues as dining halls, student unions and snack bar/cafe´s. ANOVA with post hoc Tukey’s B and T tests were used to distinguish differences between dining venues and associated institutions by size. SETTING The study was conducted at fifteen US post-secondary institutions, 2009–2011. SUBJECTS Data presented are from a sample of 175 restaurants and sixty-eight on-campus dining venues. RESULTS There were minimal differences in dining halls by institution size, although medium-sized institutions as compared with small-sized institutions offered significantly more healthful side dish/salad bar items. Dining halls scored significantly higher than student unions or snack bar/cafe´s on healthful entre´es, side dish/salad bar and beverages offerings, but they also had the most barriers to healthful dietary habits (i.e. all-you-can-eat). No differences were found by restaurant type for NEMS-R scores for total restaurant dining environment or healthful entre´es and barriers. Snack bars had more healthful side dishes (P50?002) and fast-food restaurants had the highest level of facilitators (i.e. nutrition information; P50?002). CONCLUSIONS Based on this evaluation in fifteen institutions, the full campus dining environment provides limited support for healthy eating and obesity prevention. The quality of campus dining environments can be improved via healthful offerings, providing nutrition information and other supports to facilitate healthy eating and prevent unwanted weight gain.

Abstract
CONTEXT The link between adolescent fiber consumption, inflammation, and body fat distribution has not been investigated. OBJECTIVE This study investigated associations of dietary fiber intake with inflammatory-related biomarkers and robust measures of total and central adiposity in a sample of 559 adolescents aged 14-18 yr (49% female, 45% Black). METHODS Fasting blood samples were measured for leptin, adiponectin, resistin, C-reactive protein, and fibrinogen. Diet was assessed with four to seven 24-h recalls, and physical activity was determined by accelerometry. Fat-free soft tissue mass and fat mass were measured by dual-energy x-ray absorptiometry. Visceral adipose tissue was assessed using magnetic resonance imaging. RESULTS Multiple linear regression, adjusting for age, race, Tanner stage, fat-free soft tissue mass, energy intake, and physical activity, revealed that dietary fiber intake was inversely associated with fat mass and serum leptin in males (all P < 0.03) but not in females. In both genders, dietary fiber intake was negatively associated with visceral adipose tissue, plasma C-reactive protein, and plasma fibrinogen and positively associated with plasma adiponectin (all P < 0.05). No relations were found between dietary fiber intake and plasma resistin in either males or females. CONCLUSION Our adolescent data suggest that greater consumption of dietary fiber is associated with lower visceral adiposity and multiple biomarkers implicated in inflammation.

Abstract
OBJECTIVE To examine the roles of gender and race in students' determinants of food choices on a college campus. METHODS A total of 405 college students participated in a survey entitled "Campus Food: You Tell Us!" Chi-square and logistic regression were used to examine associations between demographics and food choice determinants. RESULTS Gender and race appeared to play a significant role in determinants of students' food dislikes. Males were significantly more likely to choose cost, taste, and poor quality over poor nutrition as determinants. White students were significantly less likely to choose cost, inconvenience, and taste over poor nutrition than students of other races. Gender was also a significant factor associated with student preferences for campus dining location and determinants of unhealthful food. CONCLUSIONS AND IMPLICATIONS Future marketing may be more effective if tailored to gender and race. Nutrition educators should consider addressing taste and convenience when attempting to influence students' food choices.

Abstract
Cereal-based food products have been the basis of the human diet since ancient times. Dietary guidelines all over the world are recommending the inclusion of whole grains because of the increasing evidence that whole grains and whole-grain-based products have the ability to enhance health beyond the simple provision of energy and nutrients. In this review we will examine the main chemical components present in whole grains that may have health enhancing properties (dietary fiber, inulin, beta-glucan, resistant starch, carotenoids, phenolics, tocotrienols, and tocopherols) and the role that whole grains may play in disease prevention (cardiovascular diseases and strokes, hypertension, metabolic syndrome, type 2 diabetes mellitus, obesity, as well as different forms of cancer). The knowledge derived from the functional properties of the different chemical components present in whole grains will aid in the formulation and development of new food products with health enhancing characteristics.

Abstract
The recently discovered SCFA-activated G-coupled protein receptors FFA receptor 2 and FFA receptor 3 are co-localised in l-cells with the anorexigenic 'ileal brake' gut hormone peptide YY, and also in adipocytes, with activation stimulating leptin release. Thus, SCFA such as acetate and propionate show promise as a candidate to increase satiety-enhancing properties of food. We therefore postulate SCFA may have a role in appetite regulation and energy homeostasis. SCFA can be delivered either directly within food, or indirectly via the colon by the provision of fermentable non-digestible carbohydrates. A review of studies investigating the effects of oral SCFA ingestion on appetite suggests that while oral SCFA ingestion is associated with enhanced satiety, this may be explained by product palatability rather than a physiological effect of SCFA. Colon-derived SCFA generated during microfloral fermentation have also been suggested to explain satiety-enhancing properties of non-digestible carbohydrates. However, findings are mixed from investigations into the effects of the prebiotic inulin-type fructans on appetite. Overall, data presented in this review do not support a role for SCFA in appetite regulation.

Abstract
OBJECTIVE To estimate current consumption of whole grains in college students and determine whether there would be an increase in whole-grain consumption after the students completed an interactive introductory nutrition course focusing on disease prevention. METHODS Eighty college students, 18-24 years old, participated in the study. Grain and whole-grain consumption, whole-grain food sources, and energy intake were measured before and after the nutrition course. Repeated-measures analysis of variance was performed. RESULTS After the study, whole-grain intake significantly increased from 0.37 ounces (oz) to 1.16 oz (P < .001), whereas total grain intake remained the same (3.07 oz). The number of whole-grain food sources increased from 7 to 11 food items after the intervention. CONCLUSIONS AND IMPLICATIONS A general nutrition course can be used as an avenue to increase whole-grain intake by college students.

Abstract
The symposium "Putting the Whole Grain Puzzle Together: Health Benefits Associated with Whole Grains" sponsored by the ASN brought together researchers to review the evidence regarding the health benefits associated with whole grains. Current scientific evidence indicates that whole grains play an important role in lowering the risk of chronic diseases, such as coronary heart disease, diabetes, and cancer, and also contribute to body weight management and gastrointestinal health. The essential macro- and micronutrients, along with the phytonutrients present in whole grains, synergistically contribute to their beneficial effects. Current evidence lends credence to the recommendations to incorporate whole grain foods into a healthy diet and lifestyle program. The symposium also highlighted the need for further research to examine the role of whole grain foods in disease prevention and management to gain a better understanding of their mechanisms of action.

Abstract
OBJECTIVE We examined dietary fiber intake, food sources of dietary fiber, and relation of dietary fiber to body composition and metabolic parameters in college students with plausible dietary reports. METHODS Students (18-24 y of age) provided data on anthropometry, fasting blood chemistries, and body composition (bioelectric impedance). Diet and physical activity were assessed with the Diet History Questionnaire and the International Physical Activity Questionnaire. Plausible dietary reporters were identified (+/-1 SD cutoffs for reported energy intake as a percentage of predicted energy requirement). Multiple regression analyses were conducted with the total (n = 298) and plausible (n = 123) samples, adjusting for age, race, sex, smoking status, physical activity, energy intake, and fat-free mass (where applicable). RESULTS Food sources of dietary fiber were similar in men and women. In the plausible sample compared with the total sample, dietary fiber was more strongly associated with fat mass (beta = -0.24, P < 0.001), percentage of body fat (beta = -0.23, P < 0.001), body mass index (beta = -0.11, P < 0.01), waist circumference (beta = -0.67, P < 0.05), and fasting insulin (beta = -0.15, P < 0.001). When the effect of sex was investigated, dietary fiber was inversely related to fasting insulin and fat mass in men and women and inversely related to percentage of body fat, body mass index, and waist circumference in men only (P < 0.05). CONCLUSION Inclusion of implausible dietary reports may result in spurious or weakened diet-health associations. Dietary fiber is negatively associated with fasting insulin levels in men and women and consistently associated with adiposity measurements in men.

Abstract
Dairy calcium may help prevent excess weight gain and obesity when consumed in adequate amounts (three or more servings per day) and combined with energy balance. This prospective cohort study was conducted to evaluate dairy intake and examine the association between low-fat dairy intake and body weight and composition changes in college students. Seventy-six college students (65 women and 11 men; mean age+/-standard error [SE]=19.2+/-0.2 years) completed 7-day food records, body height (cm), weight (kg), and waist circumference (cm) measurements twice (September 2004 and April 2005). Percentage of truncal fat and percentage of total body fat were measured by dual-energy x-ray absorptiometry. One-way multivariate analysis of covariance was conducted. Overall (mean+/-SE) total dairy (1.4+/-0.1 servings/day), low-fat dairy (0.5+/-0.1 servings/day), and calcium (815+/-41 mg/day) intakes were low. Subjects who consumed a higher amount of low-fat dairy products (mean+/-SE=0.8+/-0.1 servings/day) had better diet quality, gained less body weight, and had reductions in waist circumference, percentage truncal fat, and percentage total body fat compared to those with lower intake (mean+/-SE=0.1+/-0.0 servings/day). Low-fat dairy intake may be associated with better diet quality and weight management in college students. Nutrition interventions in young adults should promote low-fat dairy intake as part of an overall healthful lifestyle.

Abstract
Young adults attending college are more vulnerable to weight gain than the general population. We sought to identify health behavior change targets related to weight management in college students. Based on the Social Cognitive Theory model for health behavior change, we investigated the health-related lifestyle behaviors and physiological characteristics of this population. Forty-three college students (18.3+/-0.1 years) completed a series of quantitative assessments (eg, body weight and composition, cardiorespiratory fitness, and diet and activity habits) and structured qualitative assessments (ie, structured interview or focus group). Participants were predominantly normal weight (mean body mass index 22.2+/-0.4) and fit (maximal oxygen consumption 50.5+/-1.5 mL/kg/minute). However, healthful eating and physical activity were not considered high priorities, despite having ample free time, high exercise self-efficacy, positive outcome expectations for exercise, and a desire to exercise more. Participants reported that regularly engaging in exercise was difficult. This may have been due to poor planning/time management, satisfaction with body image, lack of accountability, and feelings of laziness. Dietary patterns generally met recommendations but were low in fruits, vegetables, and whole grains. Social support for exercise and healthful dietary habits were important factors associated with health behaviors. Students reported a decline in exercise and dietary habits relative to high school, which may have contributed to college weight gain. Our results suggest that this population may not have adequate self-regulatory skills, such as planning and self-monitoring, to maintain healthful behaviors in the college environment. Food and nutrition professionals working with young adults attending college may use these findings to guide the behavioral therapy component of their weight management medical nutrition therapy goals and outcomes.
