RESUMO
Dietary intake and alcohol consumption might be influenced by genetic variations in taste receptor genes. The objectives of this study were to examine the relationship between polymorphisms in the bitter taste receptor genes TAS2R13 (rs1015443) and TAS2R38 (rs1726866, rs10246939, and rs713598) as well as alcohol consumption and body fat percentage in college students. Four hundred and two students with a mean age of 20.2 years participated in this study. An NIH Diet History Questionnaire (DHQ II) was used to collect data on their dietary intake, while an AUDIT survey was used to determine their level of alcohol consumption. Bitter taste receptor gene polymorphisms were assessed by TaqMan allelic discrimination assays. Despite significant associations between TAS2R13 (rs1015443) and certain aspects of alcohol consumption, including the frequency of alcohol intake, no significant associations were found between TAS2R13 (rs1015443) and alcohol consumption after accounting for confounding variables in the regression model. Neither association was found regarding percent of body fat. In contrast, ethnicity and gender significantly influenced percent of body fat (p < 0.001), while no significant association was observed between TAS2R13 (rs1015443) and percent of body fat. Likewise, TAS2R38 (rs1726866, rs10246939, and rs713598) demonstrated no significant association with alcohol consumption and percent of body fat. These results were controlled for confounding factors, such as ethnicity and gender. Body fat percentage and alcohol consumption may be influenced by ethnicity, gender, and age rather than SNPs of TAS2R13 and TAS2R38 genes. Assessing taste genes' interactions with diet and body composition might be useful in identifying human disease risk.

INTRODUCTION: fish can be an affordable and accessible animal-source food in many Low- and Middle-Income Countries (LMIC). BACKGROUND: Traditional fish processing methods pose a risk of exposing fish to various contaminants that may reduce their nutritional benefit. In addition, a lack of literacy may increase women fish processors' vulnerability to malnutrition and foodborne diseases. OBJECTIVE: The overall aim of the project was to educate women and youth fish processors in Delta State, Nigeria about the benefit of fish in the human diet and to develop low literacy tools to help them better market their products. The objective of this study was to describe the development and validation of a low-literacy flipbook designed to teach women fish processors about nutrition and food safety. METHOD: developing and validating instructional material requires understanding the population, high-quality and relevant graphics, and the involvement of relevant experts to conduct the content validation using the Content Validity Index (CVI) and the index value translated with the Modified Kappa Index (k). RESULT: The Item-level Content Validity Index (I-CVI) value of all domains evaluated at the initial stage was 0.83 and the Scale-level Content Validity Index (S-CVI) was 0.90. At the final stage, the material was validated with CVI 0.983 by four experts and satisfied the expected minimum CVI value for this study (CVI ≥ 0.83, p-value = 0.05). The overall evaluation of the newly developed and validated flipbook was "excellent". CONCLUSIONS: the developed material was found to be appropriate for training fish processors in Nigeria in nutrition and food safety and could be modified for a population of fish processors in other LMICs.

OBJECTIVE: The purpose of this study was to investigate the association between sugar and NNS consumption with body fat percentage in young adults. METHODS: 524 college students were asked to complete the Web-based National Institutes of Health (NIH) Diet History Questionnaire II and had their body fat percentage measured using a bioelectrical impedance analysis scale. RESULT: One-fourth of the participants were classified as overfat/obese and of those overfat or obese, 49% of them were African American. Overfat/obese participants consumed significantly more sugar than the heathy group and the underfat group (p < 0.001). Saccharin consumption was significantly higher in the overfat/obese group compare to the underfat and normal groups (p < 0.001). The odds of becoming overfat/obese increased 1.2 times for excessive total sugar consumption (95% CI: 1.0-1.8, p < 0.05). CONCLUSION: Excessive sugar and saccharin consumption were associated with higher body fat percentage in young adults.
RESUMO
Food insecurity has emerged as a leading health care problem in the United States, impacting college students' health, well-being, and academic performance. The aims of this study were: (1) to assess the prevalence of food insecurity, (2) to identify college students' perceptions about food access resources, and (3) to explore students' expressed needs from the university in improving food security status. A mixed-methods approach was used to assess the quantitative and qualitative aspects of the study aims. An online survey to gather demographic information and assess food security status using the 6-item version of the US Household Food Security Scale Module (HFSSM) was administered. Next, qualitative focus groups with subsets of participants was conducted to gain further insight into the perceptions, coping mechanisms, and resource utilization issues related to food insecurity. This study found 34.1% of undergraduate college students to be food insecure and demonstrates that students with a meal plan are less likely to be food insecure (p = 0.012; OR = 0.68; 95% CI = 0.489, 0.918). Qualitative data identified key influencers of food insecurity: (1) personal beliefs, (2) life skills, and (3) the university. The results of this study contribute to the literature focused on food insecurity prevalence in college students and presents insight from the college student perspective. Findings may support the development of relevant interventions that are congruent with students' needs, enhancing resource utilization to increase food security status among college students.

A growing body of evidence suggests that food insecurity is associated with adverse mental health outcomes such as depression and anxiety. In this study, the relationship between food insecurity and depression was examined using data from the 2005−2016 National Health and Nutrition Examination Survey (NHANES). Food insecurity was assessed with the 18-item United States Food Security Survey Module with zero affirmative responses indicating high food security, 1 or 2 affirmative responses indicating marginal food security, and ≥3 affirmative responses indicating food insecurity. Depression was assessed with the Patient Health Questionnaire-9 with scores ≥10 indicating depression. Data were analyzed from 28,448 adult participants aged 20 or older. Food insecurity was present in 19.2% of the sample population (n = 5452). Food security status was significantly associated with gender, race, education level, marital status, smoking status, and BMI (Rao-Scott chi-square, p < 0.05). Fully food secure and very low food security adults experienced depression at a rate of 5.1% and 25.8%, respectively (Rao-Scott chi-square, p < 0.0001). Participants with very low food security had a significantly greater odds of depression than food secure adults, OR = 3.50 (95% CI: 2.98, 4.12). These findings suggest that food insecurity is a significant risk factors for depression in US adults over 20 years of age. To address this issue in our citizenry, police initiatives and public health interventions addressing both food access and mental health should be prioritized.

Malnutrition and hunger can lower a child's ability to learn effectively. Many countries in Africa experience high rates of childhood undernutrition, and school feeding programs are a common tool used to address this challenge. A systematic review was conducted to evaluate the effect of school-provided meals on educational outcomes in preschool and primary school children. Specific outcomes of interest in this review included test scores, attendance, and enrollment rates. PubMed and Scopus were used for an electronic search of relevant studies. Studies included in this review were randomized and non-randomized controlled trials, prospective cohort studies, controlled before-after studies, and pre/post-test design studies published in the past 10 years in English in sub-Sahara Africa. Findings from the nine studies included in this review suggest a positive correlation between school feeding programs and educational outcomes. Although mealtime may reduce classroom time, the benefits of providing a meal outweigh the potential loss of learning time because hungry children may not learn as effectively. In conclusion, it is recommended that school meal programs be implemented and expanded. To improve general wellbeing and learning capabilities of children, school meals should be employed starting at a young age. More research on school feeding programs is needed concerning the preschool age group (2-5 years), as there is a limited amount of information in this area.

The developing human brain requires all essential nutrients to form and to maintain its structure. Infant and child cognitive development is dependent on adequate nutrition. Children who do not receive sufficient nutrition are at high risk of exhibiting impaired cognitive skills. This systematic review aimed to examine the effects of nutritional interventions on cognitive outcomes of preschool-age children. PubMed, PsycInfo, Academic Search Complete, and Cochrane Library electronic databases were searched to identify Randomized Controlled Trials (RCTs) published after the year 2000. Studies assessing the effects of food-based, single, and multiple micronutrient interventions on the cognition of nourished and undernourished children aged 2-6 years were deemed eligible. A total of 12 trials were identified. Eight out of the twelve studies found significant positive effects on cognitive outcomes. Iron and multiple-micronutrients supplementation yield improvements in the cognitive abilities of undernourished preschool-age children. Increased fish consumption was found to have a beneficial effect in the cognitive outcomes of nourished children. On the other hand, B-vitamin, iodized salt, and guava powder interventions failed to display significant results. Findings of this review highlight the importance of adequate nutrition during preschool years, and the crucial role sufficient nutrition plays in cognitive development.

BACKGROUND: Different taste preferences correlated with genetic variations may lead to food consumption patterns that contribute to nutrient-related health outcomes such as hypertension. OBJECTIVES: The aim of this study was to determine whether single nucleotide polymorphisms (SNPs) in the salt taste receptor genes SCNN1B and TRPV1 affect salt taste perception among normotensive and hypertensive people. MATERIALS AND METHODS: We conducted a cross-sectional case control study by design consisting of a normotensive and hypertensive group. Participants were 253 adults with age range of 20-82 residing in Mississippi, USA. For each of 128 normotensives and 125 hypertensives, the salt taste recognition threshold and salt taste receptor genotype were determined. RESULTS: The hypertensive group had a higher salt taste recognition threshold than the normotensive group (P < 0.001). The polymorphism of TRPV1, rs4790522, with the AA genotype was associated with a higher salt recognition threshold (lower salt taste sensitivity) in people with hypertension and obesity. Moreover, the polymorphism of TRPV1, rs8065080, and SCNN1B, rs239345, genes were associated with a risk of hypertension (P=0.016 and P=0.024). CONCLUSION: Correlations between SNPs, salt taste sensitivity, and hypertension risk were observed. People with hypertension had a higher salt taste threshold than those with normotension.
RESUMO
OBJECTIVES: Bitter taste perception affects food preference, eating behavior, and nutrient intake. The purpose of this study was to investigate the contribution of bitter taste gene polymorphisms to body fatness as measured by percentage of body fat. METHOD: Three common single nucleotide polymorphisms (SNPs) of the TAS2R38 gene which result in amino acid changes in the protein (A49P, V262A, and I296V), were studied in three racially diverse groups: European Americans n = 313, African Americans n = 109, and Asians n = 234. RESULTS: The allele frequencies of the three SNPs were similar to previous studies. The rare haplotypes, AAI and AAV, were found in high prevalence in the African American subgroup (22.94%) and European American subgroup (6.07%). The PROP non taster; AVI/AVI diplotype was associated with a higher risk of obesity in European American and Asian but not African American subjects after age adjustment. CONCLUSIONS: TAS2R38 polymorphisms could be associated with obesity development. In addition to taste perception, nutrient sensing and energy metabolism should be studied in relation to bitter taste receptors to confirm the association between genetic polymorphisms and body fatness. Genetic polymorphisms, race, gender, and environmental factors such as dietary patterns could all contribute to body fat.
RESUMO
Food insecurity is common among college students in the United States and is associated with poorer health-related outcomes and academic performance. The aims of this study were to assess the prevalence of food insecurity at a large, public university in Mississippi, a state with the second highest rate of food insecurity in the nation, and to examine the associations between food insecurity, depression, and race in this group of students. Food security was measured using the United States Department of Agriculture Household Food Security Survey Module: Six-Item Short Form, and depression was measured using the Patient Health Questionnaire-9. In total, 131 students ages 18-24 participated in the study. Food insecurity was present in 38.2% of students surveyed. The odds of food insecurity were higher among African American students compared to Caucasian students (OR = 3.50, 95% CI: 1.38, 8.90). Students with very low food security had 4.52-times greater odds of having depression than food-secure students (p = 0.011, 95% CI: 1.42, 14.36). Neither body mass index nor body fat percentage were associated with food security status. Further research is needed on strategies to address the risk of depression among food-insecure college students and the racial disparity in food insecurity rates present among college students.

Communicating scientific results with community partners is often lacking in intervention programs, thus eB4CAST was developed to facilitate impact sharing. This article investigated using the eB4CAST dissemination tool to communicate impact from a campus-based obesity prevention program. Data from Get Fruved RCT university sites collected at baseline were used to generate eB4CAST reports. Experts (n = 13) and RCT sites (n = 15) were asked to provide feedback on eB4CAST reports based on appeal, understanding, and clarity. On all Likert items, participants rated above 7 on each (out of 10). Positive responses from open-ended questions included eB4CAST reports being clear, visually appealing, and aid in program understanding. Overall, eB4CAST was successful in relaying data and information for the Get Fruved program, thus a means for science communication that could be used in interventions. Utilizing infographics to report data and information is a feasible way to disseminate and communicate in a cost-effective, timely manner.
