Few school-age youth consume the recommended amounts of fruits and vegetables, and increasing fruit and vegetable intake in children and adolescents is an important public health goal to maintain long-term good health and to decrease risk of chronic disease and obesity. School salad bars are an important tool to promote fruit and vegetable consumption among schoolchildren. Studies show that introduction of school salad bars increases the amount and variety of fruits and vegetables consumed by children in schools. However, many schools cannot afford the capital investment in the salad bar equipment. In 2010, the National Fruit & Vegetable Alliance (NFVA), United Fresh Produce Association Foundation, the Food Family Farming Foundation, and Whole Foods Market launched Let’s Move Salad Bars to Schools (LMSB2S) in support of First Lady Michelle Obama’s Let’s Move! initiative. The goal of LMSB2S is to place 6000 salad bars in schools over 3 years. As of June, 2012, over 1400 new salad bar...

Agricultural water is a precious and limited resource. Increasingly more water types and sources are being explored for use in irrigation within the United States and across the globe. As outlined in this chapter, the Produce Safety Rule (PSR) in the Food Safety and Modernization Act (FSMA) provide irrigation water standards for application of water to fruits and vegetables consumed raw. These rules for production and use of water will continue to develop and be required as the world experiences aspects of a changing climate including flooding as well as drought conditions. Research continues to assess the use of agricultural water types. The increased use of reclaimed water in the United States as well as for selected irrigation water needs for specific crops may provide increased water availability. The use of surface water can be used in irrigation as well, but several studies have shown the presence of some enteric bacterial pathogens (enterohemorrhagic E. coli, Salmonella spp. ...

Objective: To evaluate the acceptance and effectiveness of repetitive nutrition-related text messages on college students' nutrition knowledge and fruit and vegetable consumption. Participants: 150 undergraduate (18-24 y) non-health major students with a texting mobile phone. Methods: The intervention group received biweekly text messages of the MyPlate icon and the USDA's Dietary Guidelines (DGs) for 7 weeks. The control group received the same information in a mailed brochure. A pre-and post-online survey assessed the students' knowledge and behavior. Results: The intervention resulted in greater MyPlate food group recognition (p<0.05) compared to control and a trend toward improved knowledge of the DGs. In the intervention group, fruit consumption was elevated (p<0.05) and a trend toward elevated vegetable consumption was determined. No gender differences in intervention effectiveness exist. Conclusion: Texting repeated messages appears to be an acceptable and effective way to increase nutrition knowledge and promote positive diet-related behaviors in college students.

Introduction Several studies have shown the effect of dietary patterns on breast cancer risk, but none has been conducted in Argentina. The aim of this study was to extract dietary patterns from Food Frequency Questioner, to estimate their effect on breast cancer occurrence while taking into account aggregation factors (family history of breast cancer) and to explore the sensitivity of the estimates to changes in the assumptions. Methods A principal component exploratory factor analysis was applied to identify dietary patterns, which were then included as covariates in a multilevel logistic regression. Family history of BC was considered as a clustering variable. A multiple probabilistic sensitivity analysis was also performed. Results The study included 100 cases and 294 controls. Four dietary patterns were identified. Traditional (fat meats, bakery products, and vegetable oil and mayonnaise) (OR III tertile vs I 3.13, 95 % CI 2.58-3.78), Rural (processed meat) (OR III tertile vs I 2.02, 95 % CI 1.21-3.37) and Starchy (refined grains) (OR III tertile vs I 1.82, 95 % CI 1.18-2.79) dietary patterns were positively associated with BC risk, whereas the Prudent pattern (fruit and non-starchy vegetables) (OR III tertile vs I 0.56, 95 % CI 0.41-0.77) showed a protective effect. For Traditional pattern, the median bias-adjusted ORs (3.52) were higher than the conventional (2.76). Conclusions While the Prudent pattern was associated with a reduced risk of BC, Traditional, Rural and Starchy patterns showed a promoting effect. Despite the threats to validity, the nature of associations was not strongly affected.

Stomach cancer is not common in Thailand but the life styles of the Thai population are changing to become more Western so that information for planning control programme of stomach cancer is necessary. The highest incidence rates of this neoplasm are found in Eastern Asia, ranging from age-standardized rates of 95.5/105 (men) and 40.1/105 (women) in Yamagata, Japan to 4.1/105 (men) and 2.1/105 (women) in Khon Kaen, Northeast of Thailand. In Thailand, the estimated age-standardized incidence rates in 1993, 1996 were 4.9/105, 4.1/105 in men and 3.0/105 , 2.6/105 in women. Risk factors for stomach cancer in Thai population are unclear, but possibly include low intake of vegetables and fruits, alcohol drinking, tobacco smoking and high intake of salt. To investigate various aspects of dietary factors, smoking, and alcohol drinking in determining risk of stomach cancer in Thai population. A case-control study was conducted in Khon Kaen, Thailand during 2002-2006, to study the role of th...

To estimate the burden of disease attributed to low fruit and vegetable intake by sex and age group in South Africa for the year 2000. The analysis follows the World Health Organization comparative risk assessment (CRA) methodology. Population-attributable fractions were calculated from South African prevalence data from dietary surveys and applied to the revised South African burden of disease estimates for 2000. A theoretical maximum distribution of 600 g per day for fruit and vegetable intake was chosen. Monte Carlo simulation-modelling techniques were used for uncertainty analysis. South Africa. Adults &gt;or= 15 years. Mortality and disability-adjusted life years (DALYs), from ischaemic heart disease, ischaemic stroke, lung cancer, gastric cancer, colorectal cancer and oesophageal cancer. Low fruit and vegetable intake accounted for 3.2% of total deaths and 1.1% of the 16.2 million attributable DALYs. For both males and females the largest proportion of total years of healthy l...

Enough solid evidence now exists to offer women several fundamental strategies for healthy eating. They include emphasizing healthful unsaturated fats, whole grains, good protein ''packages,'' and fruits and vegetables; limiting consumption of trans and saturated fats, highly refined grains, and sugary beverages; and taking a multivitamin with folic acid and extra vitamin D as a nutritional safety net. A diet based on these principles is healthy through virtually all life stages, from young adulthood through planning for pregnancy, pregnancy, and on into old age.

Objective To assess the effectiveness of an intervention aimed to increase adherence to a Mediterranean diet. Design A 12-month assessment of a randomized primary prevention trial. Subjects/settings One thousand five hundred fifty-one asymptomatic persons aged 55 to 80 years, with diabetes or Ն3 cardiovascular risk factors.

The present work describes a method for determining ascorbic acid, which combines iodometry with a voltammetric technique to detect the end point of the titration. In addition, the validity of the method applied to natural vegetable or fruit samples was assessed. The results were compared with those obtained by an accurate method such as HPLC using UV detection. Similar values of ascorbic acid for different natural samples were obtained by means of this approach (p > 0.05). The limit of quantification was 0.1 mg. This technique presents the advantage of other electroanalytical methods such as avoiding filtration or ultracentrifugation steps, with the additional benefit of using the platinum electrodes, which are routinely used in the laboratory. These facts allow a rapid and efficient quantification of ascorbic acid with very low cost of reagents and equipment.

Background Data on large scale community-level interventions on fruit and vegetable consumption targeting minority communities are lacking. This study examined whether a multicommunity intervention decreased disparities in fruit and vegetable consumption. Materials and Methods The Racial and Ethnic Approaches to Community Health (REACH) 2010 program was conducted among 16 black communities. Five-year trends (2001-2006) in self-reported fruit and vegetable consumption among the target population were compared with trends among white and black populations in 14 states where communities were located. Results The geometric mean of combined fruit and vegetable consumption in the REACH communities increased 7.4 % (P<0.001) but did not change among white and black populations in comparison states (P>0.05). Increased consumption in REACH communities was higher in the lower quintiles of consumptions. The disparity in fruits and vegetables consumption between comparison white population and blacks in REACH communities decreased by 33 %-from 0.66 to 0.44 times per day. The target population of 1.2 million people consumed fruits and vegetables about 21.9 million additional times per year as a result of the REACH program. Conclusion This large community-based participatory intervention successfully reduced disparities in fruit and vegetable consumption between comparison white population and 16 disadvantaged black communities.

There is a theoretical basis for believing that healthy lifestyle interventions can improve mental well-being and evidence to show that mental well-being is protective of future health. This study contributes to the evidence base by examining changes in mental well-being associated with the One Body One Life (OBOL) healthy lifestyle programme in a community setting in the West Midlands. Quantitative, before and after the evaluation. We conducted a before and after study of the lifestyle intervention &#39;OBOL&#39;, a multi component intervention that includes exercise and healthy eating education. Mental well-being was measured with the Warwick-Edinburgh Mental Well-being Scale. Physical activity and fruit and vegetable consumption were self-reported. Measures were collected before and after the 12-week intervention and three months post completion. Non-parametric tests were used to assess differences between groups, and linear mixed models were used to assess change over time. Four...

Background: Measurement of social cognitive variables is often restricted to long-term and health-related outcomes. A more comprehensive measurement of cognitive determinants would enable evidence-based design of health behavior interventions with a focus on the most relevant targets. The purpose of this study was to examine the relative impact of different social cognitive determinants on fruit and vegetable (FV) and fast food consumption. Methods: Finnish male conscripts (N = 855, age M = 20) filled in questionnaires on social cognitive factors when entering the military service, and on food consumption frequency after two months. The data were analysed using structural equation modeling. Results: Physical well-being expectation and bad taste expectation were most strongly related to both FV and fat avoidance intentions. Perceived weight gain risk predicted fat avoidance intention, whereas perceived risk for other health problems predicted FV intention. Social self-efficacy was associated with FV intention only. Consumption of both FV and fast food was predicted by action planning and intention. Conclusions: A more careful evaluation of subtypes of social cognitions sheds light on the specific content behind motivation. Such understanding might help in designing more effective intervention messages.

The effects of the administration of 50 mg of guggulipid or placebo capsules twice daily for 24 weeks were compared as adjuncts to a fruit- and vegetable-enriched prudent diet in the management of 61 patients with hypercholesterolemia (31 in the guggulipid group and 30 in the placebo group) in a randomized, double-blind fashion. Guggulipid decreased the total cholesterol level by 11.7%, the low density lipoprotein cholesterol (LDL) by 12.5%, triglycerides by 12.0%, and the total cholesterol/high density lipoprotein (HDL) cholesterol ratio by 11.1% from the postdiet levels, whereas the levels were unchanged in the placebo group. The HDL cholesterol level showed no changes in the two groups. The lipid peroxides, indicating oxidative stress, declined 33.3% in the guggulipid group without any decrease in the placebo group. The compliance of patients was greater than 96%. The combined effect of diet and guggulipid at 36 weeks was as great as the reported lipid-lowering effect of modern drugs. After a washout period of another 12 weeks, changes in blood lipoproteins were reversed in the guggulipid group without such changes in the placebo group. Side effects of guggulipid were headache, mild nausea, eructation, and hiccup in a few patients.

Sporotrichosis is the most common subcutaneous mycosis in South America. Classic infection is associated with traumatic inoculation of soil, vegetables, and organic material contaminated with Sporothix schenckii. Animals of various species, including humans, are affected by this disease. This subcutaneous mycosis is an infection of implantation. The most frequent clinical form is the lymphocutaneous form. The fixed cutaneous form is characterized by infiltrated nodular, ulcerated, or erythematosquamous lesions located on exposed areas where fungal inoculation occurred. The disseminated cutaneous forms have mainly been observed among immunosuppressed patients, especially human immunodeficiency virus-positive individuals. Sporotrichosis is the only subcutaneous mycosis for which direct examination or histology is of little or no value for diagnosis. The diagnosis rests solely on the isolation of S schenckii in culture. Since 1998, researchers from Brazil suggested that feline transmis...

Five different fractions of the biodegradable municipal solid waste (BMSW) were evaluated as potential animal feedstuffs. For each source of waste (meat waste (MW), fish waste (FW), fruit and vegetables waste (FVW), restaurant waste (RW), household waste (HW)), samples were obtained from small shops (butchers, fishmongers, fruit and vegetable shops), restaurants and a MSW treatment plant (household waste). The chemical composition, microbiological characterization, dioxins, furans, PCBÕs and mineral content were determined for every type of waste fraction.

Non-Hodgkin's lymphoma is etiologically related to suppressed immune status, and certain nutrients found in fruits and vegetables have been associated with increased immune responses. However, limited information exists on associations between intake of fruits, vegetables, and related nutrients and non-Hodgkin's lymphoma risk. We thus examined these associations among 88,410 women in the Nurses' Health Study cohort who were aged 34 -60 years in 1980 and provided dietary information in 1980. During 14 years of follow-up, we documented 199 incident cases of non-Hodgkin's lymphoma. Higher intake of fruits and vegetables was associated with a lower risk of non-Hodgkin's lymphoma (P for trend ‫؍‬ 0.02); the multivariate relative risk (RR) was 0.62 [95% confidence interval (CI), 0.38 -1.02] for women who consumed greater than or equal to six servings per day as compared with those consuming less than three servings per day. When fruits and vegetables were examined separately, intake of vegetables rather than fruits was most clearly associated with a reduced risk (P for trend ‫؍‬ 0.02 for vegetables; P for trend ‫؍‬ 0.16 for fruits); compared with those consuming less than one serving per day, the multivariate RRs were 0.62 (95% CI, 0.35-1.07) for women who consumed greater than or equal to three servings per day of vegetables and 0.70 (95% CI, 0.44 -1.12) for women who consumed this amount of fruits. Higher intake of cruciferous vegetables was also associated with a decreased risk (P for trend ‫؍‬ 0.03); the multivariate RR was 0.67 (95% CI, 0.40 -1.11) for women who consumed greater than or equal to five servings per week as compared with those consuming less than two servings per week. These associations were slightly attenuated when we additionally adjusted for intake of beef, pork, or lamb as a main dish. Intake of dietary fiber from vegetable sources was related to a reduced risk; the multivariate RR was 0.54 (95% CI, 0.34 -0.87) for women in the highest quintile as compared with those in the lowest quintile (P for trend ‫؍‬ 0.01), and it was slightly attenuated with additional adjustment for saturated and trans unsaturated fats. However, we observed no associations between intakes of specific dietary carotenoids, vitamins A, C, E, and folate, and non-Hodgkin's lymphoma risk. Higher intake of vegetables, particularly cruciferous vegetables, may reduce the risk of non-Hodgkin's lymphoma among women.

The purpose of this study was to explore the relationships among the variables of the dietary consumption and the anthropometric measurements of Filipino Americans (FAs). The study sample consisted of 128 participants residing in the US who completed two questionnaires and biometric measurements. Strong positive correlations between the consumption of fat and sugar and body mass index (BM) among the participants were found. In contrast, the correlations between the consumption of fruits and vegetables and BMI were strongly negative. This study advances the limited body of knowledge on the dietary practices of FAs in the US.

The aim of this research was to evaluate the fertilizing capacity of an innovative zeolite product, characterised by an encapsulated structure with an organic matrix on vegetable and ornamental plants and the interaction with soil microorganisms present in the cultivation substrates. The experiments, started in January 2021, were conducted in the greenhouses of CREA-OF in Pescia (PT), Tuscany. The experimental groups were: i) group control, irrigated with water and substrate previously fertilized; ii) group with zeolite 21% ammoniacal nitrogen; iii) group with zeolite coated with Ecoat; iv) group with zeolite 21% ammoniacal nitrogen, SO3 57.7% with nitritification inhibitor dcd (dicyandiamide) and DMPP 3,4 dimethylpyrazole-phosphate. The trial carried out on strawberry and Polygala myrtifolia actually showed how the use of zeolite can improve the fertilizing properties of the substrate. In particular, the use of encapsulated zeolite resulted in an increase in plant height, vegetative and root weight, number and flowers life, number and weight of fruits in strawberry and Polygala myrtifolia. In addition, there were changes in substrate pH, microbiological count and nitrogen, phosphorus and potassium content depending on the type of zeolytic product used. Research has shown that the use of loaded zeolite can significantly improve the agronomic and production quality of strawberry and Polygala myrtifolia plants. For example, Ecoat treatment with zeolite encapsulated with organic matrices in strawberries resulted in a pot production of 39.61 fruits and a weight of 36.39 g/fruit, compared to 24.21 and 26.48 g/fruit for the untreated control. While in Polygala myrtifolia the same treatment (Ecoat) resulted in 48.00 flowers per plant and a flowers life of 9.20 days compared to 34.86 flowers and 6.20 of the control. The trial also showed that treatment with Ecoat can promote the development of microbial colonies in the substrate, 3.5 x 104 cfu/g compared with 2.3 x 102 cfu/g in the control in strawberries and 3.2 x 104 cfu/g compared with 2.6 x 102 cfu/g in Polygala myrtifolia. In addition, the application of these aluminosilicates in substrates can influence the pH and the microbial component that is essential for the cultivation and defence of plants. The Ecoat product that performed best in the trial can play the role of both a nitrogen based fertiliser and, thanks to its organic matrix, of stimulating microbial development in the substrate in which the plants are grown.

Coniothyrium minitans, a mycoparasite of sclerotia of Sclerotinia sclerotiorum and Sclerotium cepivorum, produced four closely related metabolites inhibitory to fungal growth. The major metabolite, identified as macrosphelide A, had IG 50 values (the concentration of metabolite to inhibit growth by 50%) of 46.6 and 2.9 Wg ml 31 against S. sclerotiorum and S. cepivorum, respectively. This is the first report of both antifungal activity due to macrosphelide A as well as isolation of macrosphelide A from C. minitans.

Cancer, a disease resulting from dysregulated cell growth control, is caused by an interaction of dietary, genetic, and environmental risk factors. Dietary factors, including physical activity, may contribute to approximately one-third of all cancers. This meta-review summarizes dietary factor and cancer risk associations and makes specific dietary recommendations to reduce risk of specific cancers. The evidence supporting specific dietary recommendations to reduce the risk of cancer is heterogeneous in its strength and consistency. Prospective epidemiologic studies have provided strong evidence supporting regular physical activity and minimal adult weight gain to lower risk of colorectal and breast cancer. The strongest evidence linking specific foods to decrease risk of certain cancers includes the consumption of fruits and vegetables and whole grains. Secondary prevention trials and observational prospective epidemiologic studies have demonstrated the efficacy of a Mediterranean-type dietary pattern to decrease risk of both cancer and cardiovascular diseases. We recommend the adoption of dietary patterns emphasizing regular physical activity, fruits and vegetables, whole grains, legumes, nuts, seeds, and lowfat dairy products to all people at risk for cancer and cardiovascular disease. These recommendations may be incorporated into enjoyable cultural food patterns as exemplified by Mediterranean-type diets. The preparation and enjoyment of meals in a convivial atmosphere is a vital component of lifestyles to prevent chronic diseases such as cancer and certain cardiovascular diseases.

Background Individuals consuming diets dense in fruits and vegetables consume an array of phytonutrients as well as recognized nutritional components, including vitamins, minerals, and fiber. There is a growing body of evidence that phytonutrients may play positive roles in health.

Although domestic computer use is increasing, most efforts to reduce energy use through improved power management have focused on computers in the workplace. We studied 20 households to understand how people use power management strategies on their home computers. We saw computers in the home, particularly desktop computers, are left on much more than they are actively used suggesting opportunities for economic and energy savings. However, for most of our participants, the economic incentives were too minor to motivate them to turn off devices when not in use, especially given other frustrations such as long boot up times. We suggest research directions for home computer power management that could help users be more green without having to dramatically change their home computing habits.

The role of dietary factors in the etiology of Crohn&#39;s disease (CD) is inconsistent largely due to difficulties in acquiring valid information on consumption habits. We examined the impact of diet on new onset CD in children using a validated food-frequency questionnaire (FFQ). A case-control study was carried out. Children &lt; or =20 yr, newly diagnosed with CD, were recruited from 3 pediatric gastroenterology clinics across Canada. Population or hospital controls were selected matched to cases for time of diagnosis (+/-6 months) and area of residence. Dietary consumption 1 yr prior to disease diagnosis was evaluated using a validated FFQ, administered within 1 month of diagnosis. Conditional logistic regression analysis adjusting for potential confounding variables (energy intake, age, gender, body mass index) was carried out. A total of 130 CD patients and 202 controls were studied. Mean age at diagnosis (+/-SD) was 14.2 (2.7). There were more male patients (59%). Comparing ...

A polymerase chain reaction (PCR) was developed for the detection of Clostridium botulinum type A, a cause of human botulism. A two primer set and an oligonucleotide detection probe were used to specifically detect Cl. botulinum type A neurotoxin gene (BoNT/A). After 40 cycles of amplification, detection of a 798 bp amplified DNA fragment was carried out by agarose gel electrophoresis and Southern blot hybridization. This assay was able to detect 12.5 fg of purified target DNA or five bacteria per reaction. The sensitivity in artificially contaminated food samples after an 18 h enrichment step ranges from 10 to 10(3) bacteria per g according to the type of food samples. No cross-reactions were observed with the other Cl. botulinum toxinotypes and other bacteria found routinely in food. This PCR method may provide a suitable and rapid alternative to standard techniques for detection of Cl. botulinum type A in food samples.

Dithiocarbamates are a class of fungicides extensively used in many crops worldwide. The current residue definition of dithiocarbamates in food for compliance with maximum residue limits, at national and international levels, is total residues arising from the use of any or each dithiocarbamate fungicide, determined as CS 2. The analytical method most frequently used to analyze dithiocarbamate residues in food for monitoring purposes was proposed more than 30 years ago. In this method, total dithiocarbamates are decomposed to CS 2 , which is purified and reacted with a cupric reagent. The yellow complex formed is quantified by spectrophotometry. In this paper, a new reaction system for the purification and complexation of CS 2 is proposed. The new system is less fragile than the traditional design, is easier to assemble, and allows for a higher sample throughput, in addition to being of low cost. Recovery of added mancozeb, thiram, or ziram (0.15-8.0 mg/kg) in rice, beans, apple, banana, orange, papaya, tomato, cucumber, and potato ranged from 82 to 120%, with relative standard deviations from 0 to 10% (n) 3 or 5). Analysis of apple, tomato, and papaya samples with field-incurred dithiocarbamate residues showed comparable results using both the traditional and the new reaction systems.

A variety of fresh market vegetables, including watermelon and tomato are economically important crops in Florida. Whitefly-transmitted Squash vein yellowing virus (SqVYV) was first identified in squash and watermelon in Florida in 2005 and shown to cause a severe decline of watermelon vines as crops approach harvest. Florida is most economically impacted by SqVYV, although the virus has been detected more recently in Indiana and South Carolina. The origin and evolutionary history of SqVYV, one of the few members of the genus Ipomovirus within the family Potyviridae, are not known. Sequence diversity of SqVYV isolates collected at different times, from different locations and from different plant species is being analyzed for insights into the origin of the virus. More recently, Cucurbit leaf crumple virus (CuLCrV) and Cucurbit yellow stunting disorder virus (CYSDV), also whitefly-transmitted, have been detected in watermelon in Florida. Tomato yellow leaf curl virus (TYLCV) was first detected in south Florida tomato crops in 1997. Several surveys have been conducted in the region to identify alternative hosts for these four viruses. Cucurbit weeds including Balsam-apple (Momordica charantia), creeping cucumber (Melothria pendula) and smellmelon (Cucumis melo var. dudaim) provide reservoirs for SqVYV, CuLCrV and/or CYSDV. Green bean (Phaseolus vulgaris) also can be a reservoir for CuLCrV. No wild hosts of TYLCV have been reported in Florida. The effectiveness of insecticides and silver plastic mulch to manage whiteflies and mitigate TYLCV has been demonstrated and is currently being evaluated for SqVYV, CuLCrV and CYSDV. In addition, potential sources of SqVYV resistance have been identified in greenhouse and field screening of watermelon germplasm. Further studies to refine these sources of resistance are underway. Lastly, a comprehensive map of 33,560 hectares (82,928 acres) of vegetable fields in the three counties comprising the majority of the southwest Florida vegetable production area has been developed to identify 'hot spots' and reservoir crops for viruses and whiteflies, and will be useful in evaluation of management strategies to decrease virus incidence in commercial fields.

Objective: To investigate changes in the consumption of fruits and vegetables in worksite canteens using the tools of continuous quality improvement, and to gain knowledge of practical strategies being effective in increasing the consumption. Design: Study design included baseline data collection, an 8 h training session for all canteen staff, goal setting, strategy development and implementation for each canteen, end-point data collection and a follow-up data collection 4 months from the end-point (1 year from baseline). The main outcome measurement was average grams of fruits and vegetables per lunch meal served per customer (net weight; potatoes not included). Setting: Five workplaces in Denmark: a military base, an electronic component distributor, a bank, a town hall and a waste-handling facility. Subjects: Work-site canteen managers, staff and customers. Results: There were significant increases in the total consumption of fruits and vegetables for all five work-site canteens from baseline to end-point, 70 g per customer on average (67, 54, 39, 88 and 103 g, respectively). The follow-up data collection showed that the canteens either maintained or significantly increased consumption, the average increase being 95 g per customer compared with baseline (77, 60, 86, 70 and 183 g, respectively). Conclusions: This study demonstrates a large potential for work-site canteens to increase customers' intake of fruits and vegetables at lunch and suggests a broad spectrum of strategies to compose meals that are both rich in fruits and vegetables and attractive to customers.

Background: Dietary lipids are one of the most effective stimulators of carotenoid absorption, but very limited data exist on the impact of endogenous food sources of lipids to enhance carotenoid absorption. The co-consumption of whole egg with carotenoid-rich foods may increase overall carotenoid absorption via lipid-rich egg yolk. Objective: We designed this study to assess the effects of egg consumption on carotenoid absorption from a carotenoid-rich, raw mixed-vegetable salad. Design: Healthy young men (n = 16) consumed the same salad (all served with 3 g canola oil) with no egg (control), 75 g scrambled whole eggs (1.5 eggs) [low egg (LE)], and 150 g scrambled whole eggs (3 eggs) [high egg (HE)] (a randomized crossover design). Control, LE, and HE meals contained 23 mg, 23.4 mg (0.4 mg from eggs), and 23.8 mg (0.8 mg from eggs) total carotenoids and 3 g, 10.5 g (7.5 g from eggs), and 18 g (15 g from eggs) total lipids, respectively. Blood was collected hourly for 10 h, and the triacylglycerol-rich lipoprotein (TRL) fraction was isolated. Total and individual carotenoid contents, including lutein, zeaxanthin, a-carotene, b-carotene, and lycopene in TRL were analyzed, and composite areas under the curve (AUCs) were calculated. Results: The total mean (6SE) carotenoid AUC 0-10h in TRL was higher for the HE meal than for LE and control meals [125.7 6 19.4 a compared with 44.8 6 9.2 b compared with 14.9 6 5.2 b nmol/ L $ 10 h, respectively (values with superscripts without a common letter differ); P , 0.0001]. The TRL AUC 0-10h of lutein and zeaxanthin increased 4-5-fold (P , 0.001), and the TRL AUC 0-10h of carotenoid not present in eggs, including a-carotene, b-carotene, and lycopene, increased 3-8-fold (P , 0.01) for the HE meal compared with the control meal. Conclusion: These findings support that co-consuming cooked whole eggs is an effective way to enhance carotenoid absorption from other carotenoid-rich foods such as a raw mixed-vegetable salad. This trial was registered at clinicaltrials.gov as NCT01951313.

The specific aim for this pilot study was to evaluate the effectiveness of a nutrition and media literacy intervention targeting elementary students and their parents. The purpose of the intervention was to increase child fruit and vegetables (FV) consumption and change the home nutrition environment (measured with FV availability and accessibility and parental social support). During the intervention, students learned about nutrition, the role media plays in shaping values concerning nutrition, and developed a media campaign for their parents. A quasi-experimental research design was used to evaluate the effectiveness of the intervention. The media intervention was effective in changing the home environment.

The Centers for Disease Control and Prevention has reported that foodborne disease outbreaks associated with fruits and vegetables increased during the past decade. This study was conducted to characterize the routes of microbial contamination in produce and to identify areas of potential contamination from production through postharvest handling. We report here the levels of bacterial indicator organisms and the prevalence of selected pathogens in produce samples collected from the southern United States. A total of 398 produce samples (leafy greens, herbs, and cantaloupe) were collected through production and the packing shed and assayed by enumerative tests for total aerobic bacteria, total coliforms, total Enterococcus, and Escherichia coli. These samples also were analyzed for Salmonella, Listeria monocytogenes, and E. coli O157:H7. Microbiological methods were based on methods recommended by the U.S. Food and Drug Administration. For all leafy greens and herbs, geometric mean indicator levels ranged from 4.5 to 6.2 log CFU/g (aerobic plate count); less than 1 to 4.3 log CFU/g (coliforms and Enterococcus); and less than 1 to 1.5 log CFU/g (E. coli). In many cases, indicator levels remained relatively constant throughout the packing shed, particularly for mustard greens. However, for cilantro and parsley, total coliform levels increased during the packing process. For cantaloupe, microbial levels significantly increased from field through packing, with ranges of 6.4 to 7.0 log CFU/g (aerobic plate count); 2.1 to 4.3 log CFU/g (coliforms); 3.5 to 5.2 log CFU/g (Enterococcus); and less than 1 to 2.5 log CFU/g (E. coli). The prevalence of pathogens for all samples was 0, 0, and 0.7% (3 of 398) for L. monocytogenes, E. coli O157:H7, and Salmonella, respectively. This study demonstrates that each step from production to consumption may affect the microbial load of produce and reinforces government recommendations for ensuring a high-quality product.

Following breast cancer diagnosis, women often attempt to modify their lifestyles to improve their health and prevent recurrence. These behavioral changes typically involve diet and physical activity modification. The aim of this study was to determine association between healthy eating habits and physical activity with quality of life among Iranian breast cancer survivors. A total of 100 Iranian women, aged between 32 to 61 years were recruited to participate in this cross-sectional study. Eating practices were evaluated by a validated questionnaire modified from the Women&#39;s Healthy Eating and Living (WHEL) study. Physical activity was assessed using the International Physical Activity Questionnaire (IPAQ). A standardized questionnaire by the European Organization of Research and Treatment of Cancer Quality of Life and its breast cancer module (EORTC QLQ-C30/+BR-23) were applied to determine quality of life. Approximately 29% of the cancer survivors were categorized as having h...

Background Fruit and vegetable (F/V) intake surveillance can provide information critical to the design and evaluation of interventions and the assessment of progress toward national intake objectives. The CDC's Youth Risk Behavior Surveillance System (YRBSS) assesses F/V intake among high school students using six questions about the frequency of intake in times per day. It is not known whether F/V intake frequency in times per day can be used as a proxy for intake in servings per day. Objective To compare F/V intake estimates based on responses to three sets of survey questions, including the standard set of six YRBSS questions, with criterion F/V intake in servings per day based on data from 24-hour dietary recall interviews. Participants/setting Study participants were 610 high school students who completed an in-class questionnaire and three telephone-administered 24-hour dietary recall interviews. The questionnaire asked students how many times they consumed 100% fruit juice and ate fruit, carrots, potatoes, green salad, and other vegetables during the "past 7 days" (set 1), the number of times they did so "yesterday" (set 2), and the number of cup-equivalents of fruits and vegetables they consumed per day (set 3). Main outcome measure Mean estimated F/V intake either as "times/day" or "servings/ day" and the percentage of students whose estimated F/V intake was !1, !2, and !3 times/day or servings/day. Statistical analyses performed t tests and corrected Pearson correlations were used to compare F/V intake estimates based on survey question responses with estimates based on responses to the 24-hour dietary recall interviews.

Objective: To explore the relationship among children's diet quality, weight status and food environment in subarctic Canada. Design: In the cross-sectional study, children's BMI was calculated, diet quality was assessed using three 24 h dietary recalls and children were asked about their home food environment and source of meals. Setting: Two Aboriginal Cree communities in northern Québec. Subjects: Two hundred and one children in grades 4-6. Results: The majority (64?2 %) of children were overweight (29?9 %) or obese (34?3 %). Weight status was not associated with reported restaurant meal frequency or the home food environment. The 18 % of children who consumed three or more restaurant meals in the three days of recall consumed, on average, 2004 kJ (479 kcal) more energy daily than children consuming no restaurant meals and had higher intakes of fat, saturated fat, Ca and soda. Most foods contributing to energy and dietary fat were energy-dense market foods of low nutritional value such as sweetened beverages and snack foods. Only 68 % of children reported often having fruits and vegetables in the home and 98?5 % of children consumed less than 5 fruits and vegetables daily. Many children (42?8 %) were at risk of Zn inadequacy. Only 19 % of children consumed 2 or more servings of milk daily, and the mean intakes of Ca and vitamin D were below the recommended adequate intake. Traditional game meat was consumed infrequently, but contributed significantly to Fe and Zn intake. Conclusions: Childhood obesity in subarctic communities prevailed in a food environment typified by high-energy-density commercial foods of low nutritional value.

Physical activity (PA) and poor fruit/vegetable intake are contributors of health disparities among African Americans (AA). In order to design effective interventions to address these behaviors, it is essential to assess where individuals are in terms of their attitudes and decisions. The aim of this study was to use the Stages of Change Model to assess AA's attitudes and decisions regarding pertinent health behaviors and provide suggestions about how to address them. A survey was administered to 242 low-income, medically underserved adults (47% AA, 27%

To simultaneously detect Sudan dyes and carotenoids in red pepper and tomato products, high-performance liquid chromatography (HPLC) methods with photodiode-array detection are developed and validated. The methods include the use of end-capped and nonend-capped adsorbents with a gradient elution system starting with water containing methanol. Water content of 9% in the starting mobile phase is found to be necessary to ensure sufficient separation of Sudan dyes and to avoid overlapping or interference with the carotenoids of considerable content. The data of the validation reveal the accuracy and precision of the developed methods. A limit of Sudan dyes detection of 1-5 µg/g in red pepper or tomato sauce could be approached. The methods provide excellent separation of the carotenoids from the unsaponified extracts of red pepper and the tomato products

ANTRACT: A carotenoid database for individual and multicomponent foods has been compiled that contains values for the five most common carotenoids (a-carotene, 3carotene,-cryptoxanthin, lycopene, lutein) in 2,458 fruits, vegetables, and multicomponent foods containing fruits and vegetables. The database was used to estimate intakes of specific carotenoids for 19-to 50-year-old women (n = 1,102), using food consumption data obtained from dietary recalls in the US Department of Agriculture Continuing Survey of Food Intake by Individuals, 1986. The major contributors of acarotene were carrots consumed as a single food or as an ingredient in multicomponent foods. Carrots, cantaloupe, and broccoli were the main sources of-carotene. Orange juices and blends, oranges, and tangerines were important contributors of-cryptoxanthin. Tomatoes and tomato products consumed as single foods or as ingredients in multicomponent foods provided most of the dietary lycopene. Contributors of lutein + zeaxanthin included collard, mustard, or turnip greens; spinach; and broccoli. The per capita consumption of total carotenoids (the sum of the five specific carotenoids) among these women was approximately 6 mg/day.
