Evaluation of the Factors Influencing Participation in the National School Lunch Program (NSLP) for Latino Students During Middle School and High School Years
Background and Purpose: In California, approximately 3.2 million students participated in the National School Lunch Program (NSLP in 2015). It is estimated that Latino students received over 760,000 meals through the NSLP program. This study evaluates factors that influence middle and high school Latino students’ participation in the (NSLP). Methods: Study participants were a convenience sample of students (n = 232) utilizing a 22-question survey tool. The independent variables were grade level, gender, ethnicity, perceived social stigma, competitive foods served on and off campus, peer influences and parental influences. The dependent variable was participation in the NSLP. T-test, ANOVA, and Stepwise multiple regression were used to answer the research questions. Results: Latino students were not significantly different from non-Latino students in their participation rates in the NSLP. There were several significant predictors of NSLP participation for Latino students. Meal eligibility was the only significant predictor of participation in the NSLP for Latino students who are low-participators. Conclusions: Latino students are different from non-Latino students in the factors that influence their participation in the NSLP. Future research is needed to clarify the factors impacting Latino NSLP participation
Cultural and Dietary Factors Influencing Traditional Latino Meal Patterns: Findings from Focus Group Discussion
Background: Despite a high prevalence of nutrition-related health disparities experienced by Latinos in the United States, there is limited recent information that can be used by health professionals to develop effective nutrition interventions for this diverse population. Purpose: The purpose of this study was to obtain qualitative information regarding usual dietary patterns of Latinos from Pomona, California, and utilize this data in the development of a tailored nutrition intervention. Methods: Latina women ages 30- 70, from a low socio-economic community sample, participated in one of three focus groups, and discussed eating patterns, recipes, and dietary concerns. Participants self-identified as the primary household food purchaser and preparer. Demographics and acculturation were assessed using validated surveys. Results: All participants (n=17) were considered less acculturated to the United States. Participants reported that traditional recipes and family preferences have the greatest influence on foods prepared, however they tend to be less healthy items. Motivators for eating healthy included maintaining family health and preventing weight gain. Barriers included conflicting meal schedules among family members and individual food preferences. Conclusion: To reduce health disparities for Latinos, cultural and dietary factors of communities, along with perceived motivators and barriers to making healthy choices, should be considered when developing tailored nutrition interventions
Four-Week Pedometer-Metered Step Walking Decreases Waist and Hip Circumference in Healthy College Students: A Pilot Study
Background and Purpose: Positive effects of pedometer-metered steps and motivation on body composition have not been documented in healthy adults. This study determined the effects of: 1) 4- weeks of pedometer-metered walking and steps on body composition, fasting blood glucose (FBG), blood pressure (BP), diet changes, waist-to-hip ratios (WHR), and 2) daily motivation on step count. Methods: For 4-weeks, participants (n=29, 24 ± 3.8yo) wore a pedometer and recorded daily steps. Subjects were randomized into two groups: 1) daily motivational quotes (MQ) (n=19) to determine changes in step counts and 2) a control group (no MQ). Measurements were performed baseline, at study end; and 3 randomized 3-day diet records were collected. Results: Waist and hip circumference decreased significantly (p=0.002 & p=0.03) in both groups and decreased fat free mass (FFM) approached significance (p=0.06). Decreased fruit intake was observed in the second (p=0.007) and third (p=0.023) diet records. Conclusion: Motivation did not increase steps or changes in FBG and BP. However, WHR decreased in both groups suggesting that 4-weeks of pedometer walking results in positive abdominal changes. Additional longer-term studies are needed to examine these physical changes as well as investigate the decreased fruit intake
Effects of Feeding Regular Eggs, N-3 Fatty Acid Enriched Eggs, and Walnuts, on Blood Lipids, Membrane Incorporation of Fatty Acids, and Serum Lutein, in Free-Living Lacto-Ovo Vegetarians
Americans do not receive enough n-3 fatty acids (F. A.) in their diets. Walnuts are good source of α-linolenic acid (ALA), while n-3 F.A. enriched eggs provide a dietary source of DHA. Whether ALA and DHA have equivalent effects modifying cardiovascular risk factors is not known. This study compared the changes in blood and erythrocyte membrane lipids in twenty free-living lacto-ovo vegetarians following the consumption of regular eggs (6/wk), n-3 F.A. enriched eggs (6/wk), or walnuts (6 oz/wk) in a triple crossover design.
Results indicate significant differences between treatments for serum triacylglycerols (TAGs), total cholesterol (TC), apo B, apo B: apo A ratio, TC: HDL ratio, and membrane differences for linolenic acid (LA), ALA, DHA, MUFA, and the ALA: LA ratio. Paired comparisons showed the walnut treatment had significantly lower values of serum TAGs, TC, apo B, ape B: apo A ratio, and TC: HDL ratio than the regular egg treatment. Walnuts significantly increased erythrocyte membrane ALA and LA compared to the egg treatments, and n-3 F.A. enriched eggs increased membrane DHA compared to the walnut treatment. The regular egg treatment increased serum TC, HDL, LDL, apo A, apo B, and the apo B: apo A ratio from baseline. The walnut treatment decreased the TC: HDL ratio, and the n-3 F.A. enriched egg treatment did not significantly change any of the blood lipid values from baseline.
We conclude walnuts and n-3 F.A. enriched eggs provide essential n-3 F.A. and may maintain optimum blood lipid parameters in healthy populations.
Lutein is a phytochemical found in egg yolk, dark green leafy and Brassica vegetables. Lutein may protect against some cancers, atherosclerosis and CVD, reduce ultraviolet radiation-induced inflammation, and is an antioxidant that quenches and scavenges photo-induced reactive oxygen species.
We tested the effects of feeding n-3 F.A. enriched eggs from flaxseed-fed chickens and regular eggs on blood serum lutein levels. The results indicate serum lutein was increased by 16.3% on the n-3 F.A. enriched egg treatment (p \u3c 0.016) and by 19.1% on the regular egg treatment (p \u3c 0.017). We conclude that both types of eggs increase serum lutein levels in healthy lacto-ovo vegetarians
The Effects of Linoleic Acid Consumption on Lipid Risk Markers for Cardiovascular Disease in Healthy Individuals: A Review of Human Intervention Trials
Cardiovascular disease (CVD) is the leading cause of death worldwide. Risk factors for developing this disease include high serum concentrations of total cholesterol, triglycerides, low-density lipoproteins, very-low density lipoproteins, and low concentrations of high-density lipoproteins. One proposed dietary strategy for decreasing risk factors involves replacing a portion of dietary saturated fatty acids with mono- and polyunsaturated fatty acids (PUFAs). The essential omega-6 PUFA, linoleic acid (LA), is suggested to decrease the risk for CVD by affecting these lipid risk markers. Reviewing human intervention trials will provide further evidence of the effects of LA consumption on risk factors for CVD. PubMed was used to search for peer-reviewed articles. The purpose of this review was: (1) To summarize human intervention trials that studied the effects of LA consumption on lipid risk markers for CVD in healthy individuals, (2) to provide mechanistic details, and (3) to provide recommendations regarding the consumption of LA to decrease the lipid risk markers for CVD. The results from this review provided evidence that LA consumption decreases CVD lipid risk markers in healthy individuals
Effect of a Garden-Based Nutrition Education Program on the Consumption of Fruits and Vegetables by Hispanic Children
Objective: A garden-based nutrition education program was developed to increase the fruit and vegetable intake among 6-to-12-year old children in an after-school setting in southern California. It was hypothesized that the intervention would increase intake and preference for fruits and vegetables. Methods: A 4-month curriculum using social cognitive theory was developed for participants at a Boys and Girls Club. A pre and post-test validated survey assessed measured fruit and vegetable intake and participants’ height and weight were measured to calculate BMI. We pilot tested an observational method of assessing snack preference. Results: Forty participants completed the study, 83% of which were Hispanic. Significant results were found in fruit and vegetable servings consumed daily (p<0.05). Self-reported scores for daily fruit servings increased from 2.23±4.18 to 4.13±2.16. Self-reported scores for daily vegetable servings increased from 2.17±1.82 to 3.07±1.87. Upward trends were shown in fruit and vegetable snack preference. Conclusions and Implications: No other garden-based nutrition education interventions have targeted primarily Hispanic youth in an extramural setting. Continued research using SCT curricula and quantitative measurements is warranted
Effects of fish oil supplementation on inflammatory acne
Abstract Background Given that acne is a rare condition in societies with higher consumption of omega-3 (n-3) relative to omega-6 (n-6) fatty acids, supplementation with n-3 may suppress inflammatory cytokine production and thereby reduce acne severity. Methods 13 individuals with inflammatory acne were given three grams of fish oil containing 930 mg of EPA to their unchanged diet and existing acne remedies for 12 weeks. Acne was assessed using an overall severity grading scale, total inflammatory lesion counts, and colorimetry. Findings There was no significant change in acne grading and inflammatory counts at week 12 compared to baseline. However, there was a broad range of response to the intervention on an individual basis. The results showed that acne severity improved in 8 individuals, worsened in 4, and remained unchanged in 1. Interestingly, among the individuals who showed improvement, 7 were classified as having moderate to severe acne at baseline, while 3 of the 4 whose acne deteriorated were classified as having mild acne. Conclusion There is some evidence that fish oil supplementation is associated with an improvement in overall acne severity, especially for individuals with moderate to severe acne. Divergent responses to fish oil in our pilot study indicates that dietary and supplemental lipids are worthy of further investigation in acne.</p
Alpha-Linolenic and Linoleic Fatty Acids in the Vegan Diet: Do They Require Dietary Reference Intake/Adequate Intake Special Consideration?
Good sources of the long-chain n-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) include cold-water fish and seafood; however, vegan diets (VGNs) do not include animal-origin foods. Typically, US omnivores obtain enough dietary EPA and DHA, but unless VGNs consume algal n-3 supplements, they rely on endogenous production of long-chain fatty acids. VGN diets have several possible concerns: (1) VGNs have high intakes of linoleic acid (LA) as compared to omnivore/non-vegetarian diets. (2) High intakes of LA competitively interfere with the endogenous conversion of alpha-linolenic acid (ALA) to EPA and DHA. (3) High somatic levels of LA/low ALA indicate a decreased ALA conversion to EPA and DHA. (4) Some, not all VGNs meet the Dietary Reference Intake Adequate Intake (DRI-AI) for dietary ALA and (5) VGN diets are high in fiber, which possibly interferes with fat absorption. Consequently, health professionals and Registered Dietitians/Registered Dietitian Nutritionists working with VGNs need specific essential fatty acid diet guidelines. The purpose of this review was: (1) to suggest that VGNs have a DRI-AI Special Consideration requirement for ALA and LA based on VGN dietary and biochemical indicators of status and (2) to provide suggestions to ensure that VGNs receive adequate intakes of LA and ALA
