RESUMEN

B group vitamins, except folate, are involved in at least one step of cellular energy production. Vegetables are considered essential for a healthy diet plan. Vegetables significantly affect diet quality by contributing to the adequate intake of some B group vitamins. Our results demonstrated that the level of vitamins B1, B2, and B3 in the studied vegetables was in the range of 9-85 µg/100 g, 22-319 µg/100 g, and 459-3497 µg/100 g, respectively. However, it is fundamental to investigate the bioaccessibility of all vitamins to identify primary dietary sources. We observed that the average bioaccessibility values for vitamins B1 and B2 were 68.9% and 63.9%, respectively. The bioaccessibility of the nicotinic acid form of vitamin B3 was 40%, while the nicotinamide form was 33.9%. As revealed in this research, the bioaccessibilities of vitamins B1, B2, and B3 in vegetables were generally low in vitro.

RESUMEN

Color is the first attribute that influences the acceptance of foods as they become more attractive to consumers when they are more intense and uniform. In recent years, the interest of producers and consumers in purchasing products containing natural ingredients have constantly increased. Natural pigments are commonly extracted from fruits and vegetables, and have been proven to provide health benefits to reduce the risk of diseases such as type-1 diabetes, obesity, and coronary diseases. Additionally, advanced extraction and encapsulation technologies that make food matrices more efficient are useful tools for improving the use of these pigments. In this review, the state-of-the-art of pigments such as carotenoids, anthocyanins, and betalains of plant origin are discussed, including their main sources of production and the factors that affect their physicochemical stability. In addition, different extraction methods are discussed, listing their advantages and disadvantages, and providing some applications of natural pigments in food.

RESUMEN

The overuse of swelling agents in fruits and vegetables has rapidly increased, resulting in food safety problems. Hence, a new method for the selective extraction and detection of thidiazuron (TDZ) and forchlorfenuron (KT30) was developed using deep eutectic solvent-molecularly imprinted hydrophilic resin (DES-MIHR) as a pipette tip solid-phase extraction (PT-SPE) adsorbent with excellent molecular recognition in aqueous matrixes. DES-MIHR interacted with TDZ and KT30 via π-π interactions and hydrogen bonding. The miniaturized PT-SPE can be performed with just 5.0 mg adsorbent, 0.3 mL water, and 0.2 mL eluent, thus having the advantage of the low consumption of adsorbent and organic reagents. The performance of the DES-MIHR-PT-SPE-high-performance liquid chromatography (HPLC) method was demonstrated with the recoveries from various fruits and vegetables being 81.1-102.9 % (RSD ≤ 7.1 %). Thereby indicating the general applicability of the developed method for the accurate determination of trace swelling agents in fruits and vegetables.

RESUMEN

Herbicides atrazine and acetochlor are used in crop production. Because of environmental and health hazards with respective maximum contamination levels of 3 and 20 ng/mL, quantifying these herbicides is important when considering presence in foods and vegetables. We utilized two Pd@Pt nanoparticle-amplified immunoassays, a colorimetric Pd@Pt nanoparticle-linked immunosorbent assay (NLISA) and differential pulse voltammetry (DPV) dependent on catalytic activity of Pd@Pt in a dual-lateral flow immunoassay (dual-LFIA-DPV). We achieved overall recoveries of 88.5-114 % in juice, fruit, and vegetable samples for both immunoassays. The NLISA yielded limits of detection (LODs) of 0.59 and 0.31 µg/kg and the dual-LFIA-DPV 0.27 and 0.51 µg/kg for the two respective species. Results for both immunoassays were validated by high-performance liquid chromatography (HPLC), for all food and drink samples though LODs are compromised when configuring the HPLC for both species with the same chromatogram. We expect Pd@Pt-based immunoassays to prove useful in various fields.

RESUMEN

The World Health Organization states prevention of chronic diseases should be based on good lifestyle behaviors and healthy diets as they can reduce the risk of chronic diseases by 80%. The theory of traditional Chinese medicine constitution (TCMC) emphasizes the congenital differences of TCMC stem from the genes of parents, while acquired differences in TCMC are caused by factors as living environments, lifestyle behaviors, and dietary habits. From the perspective of preventive medicine, this study explores the correlation between dietary habits and lifestyle behaviors as potential risk factors for different types of TCMC-balanced constitution, Yang deficiency, Yin deficiency, and Phlegm stasis. Research data were collected from 2760 subjects aged 30 to 70 years participating in a survey conducted by Taiwan Biobank in 2012 to 2017. The survey included basic demographic characteristics, lifestyle behaviors, and dietary habits along with a Body Constitution Questionnaire. Compared to men, women were 3 to 4 times more likely to develop Yang-deficiency, Yin-deficiency, and Phlegm stasis. Variables that affected TCMC were smoking, midnight snack consumption, consumption of gravy-soaked or lard-soaked rice/noodles, deep-fried soybean products, bread spread, pickled vegetables as side dishes for the main course of a meal, and the dietary habit of vegetables or fruits instead of high-fat desserts. Poor dietary habits and lifestyle behaviors are the cause of unbalanced TCMCs. Understanding the specific TCMC of individual can provide useful information and predictions to maintain physical health and achieve early disease prevention to meet the goal of preventive medicine.

RESUMEN

BACKGROUND & AIMS: This study aimed to describe the association of healthy eating literacy (HEL) with energy, nutrients, and food consumption in young women who had normal and lean weight at a Japanese university, considering their resident status. METHODS: Cross-sectional data from the Ochanomizu Health Study were used in this study. Participants answered a self-administered, two-part, anonymous survey in 2018 and 2019. A total of 203 female undergraduate students with lean and normal body mass index (BMI) were included in the analysis. Single and stepwise multiple linear regression analysis was used to examine the association of HEL and resident status with healthy food consumption, such as vegetables, fish, and shellfish. The dependent variables were HEL and resident status, and the covariates were age, BMI, and the total metabolic equivalents. RESULTS: The median (25th and 75th percentiles) age, BMI, and total HEL score were 20 (19, 21) years, 20.2 (18.9, 21.3) kg/m 2, and 18 (16, 20), respectively. Resident status and HEL were independently associated with vegetables, fish, and shellfish intake. Participants who had higher total HEL scores and lived in their family home consumed significantly more vegetables (ß = 0.17 and -0.34, p < 0.05) and fish and shellfish (ß = 0.24, -0.28, p < 0.001). CONCLUSION: This study provides an insight into the association between HEL and dietary consumption in young women with normal and lean BMI.

RESUMEN

<b>Background and Objective:</b> Nitrogen is an essential macronutrient for plant growth, improving the absorption and utilization of some other nutrients and controlling total plant development. Compost tea (CT) is an aqueous extract of compost that contains high organic matter levels necessary for plants and aerobic soil microorganisms. <i>Spirulina platensis</i> is a multi-cellular blue-green micro-alga that contains green pigments, high levels of nutrients and plant growth regulators. This work was designed to study the possibility of using CT and <i>S. platensis</i> algae culture filtrate (ACF) in improving plant growth, yield and quality of sugar beet grown under different nitrogen fertilizer levels. <b>Materials and Methods:</b> Two field experiments were conducted at Ismailia Research Station, Ismailia Province, Egypt, during the 2019/2020 and 2020/2021 seasons. The study involved two N levels (90 and 120 kg/fed), three CT rates (without, 30 and 60 l/fed) and three ACF levels (without, 1 and 2 l/fed) three times. A split-plot design was used. <b>Results:</b> Adding 120 kg N/fed increased crop growth rate (CGR), root yield/fed (RY) and sugar yield/fed (SY), while, sucrose (%) and quality index (QI) decreased. Soil drench with 60 l CT/fed incremented leaf area index (LAI), CGR, sucrose (%), RY and SY. Increasing ACF level up to 2 l/fed increased LAI, sucrose (%), QI, RY and SY. Root yield was positively correlated with SY and negatively with QI. <b>Conclusion:</b> Applying 90 kg N/fed combined with a soil drench of 60 l CT/fed and foliar spraying with 2 l ACF/fed thrice can be recommended to attain economical root and sugar yields.

RESUMEN

<b>Background and Objective:</b> In high plants, the 70 kDa heat stress proteins (Hsp70-s) have been regarded as one of the vital components of the cellular network of chaperones and folding catalysts that play important roles in numerous biological processes during growth and development. The Hsp70 families have been reported in many plant species, unfortunately, no information on this important protein family in papaya (<i>Carica papaya</i>). The objective of this study was to provide comprehensive information on the CpHsp70 family in papaya. <b>Materials and Methods:</b> The <i>CpHsp70</i> genes in the papaya genome were identified by a basic local alignment search tool against the papaya genome database by using well-known <i>Arabidopsis</i> Hsp70-s. Sequences were then analyzed by various bioinformatics tools to investigate the characteristics of the CpHsp70 family. <b>Results:</b> A total of 12 members of the CpHsp70 family has been identified and characterized in papaya. By using various computational tools, these results revealed that all general characteristics of the CpHsp70 family, like physic-chemical parameters, gene structure, phylogenetic tree and subcellular localization were provided. The transcriptome atlas was applied to re-analyze the expression patterns of genes encoding the CpHsp70 family in major tissues/organs during the growth and development of papaya plants. <b>Conclusion:</b> Results from this work exhibited the characteristics and expression analysis of the <i>CpHsp70</i> genes of this important tropical fruit crop. Taken together, this study could provide a solid foundation of the CpHsp70 family, which will be helpful in the construction of stress tolerance in papaya plants.

RESUMEN

Trace and potentially toxic elements represent one class of food contaminants that has stimulated research. In markets, two main methods of growing vegetables are generally available: conventional and organic. Conventional farming has been the target of some concerns about the use of agrochemicals, especially the excessive use of pesticides, whereas organic agriculture minimizes the use of agrochemicals. As the main route for potentially toxic elements' absorption by humans is by food intake, it is important to evaluate if the method of cultivation influences their concentrations. This study evaluated the levels of potentially toxic elements and nutrients on four leafy vegetables: curly lettuce, collard greens, escarole, and rocket, cultivated by conventional and organic farming. We found that Al, Ba, Fe, and Sr levels were higher in conventional samples, whereas K, Pb, and Zn were higher in organic. Amongst the elements analysed, values of Fe, Al, and K were around 0.2, 0.3, and 70 g kg-1, respectively, except in collard greens, in which the values were lower. On the other hand, Ba, Sr, and Mn presented higher concentration in collard greens compared to the other vegetables in conventional cultivation (~ 35, 80, and 120 mg kg-1, respectively). The principal component analysis result shows that the samples were grouped according to the type of vegetable, regardless of the type of cultivation. Despite this, the evaluation of the cultivation by different types of farming is important in order to choose the healthiest option.

RESUMEN

Fruits and vegetables are widely known to be rich in nutrients, antioxidants, vitamins, dietary fiber, minerals, and a bioactive molecule, making them an essential component of a balanced diet with multiple documented positive effects on human health. The probiotication of plant-based juices for the production of functional and nutraceutical food serves as a healthy alternative to dairy probiotics. They are cholesterol free, lack several dairy allergens, and also encourage ingestion for people with lactose intolerance. This review highlights valuable claims regarding the efficacy of different probiotic strains on various diseases. A comprehensive nutrition comparison and the preference of plant-based over dairy probiotic drinks is also discussed, supported with updated market trends of probiotic drinks (dairy and non-dairy based). An extensive compilation of current plant-based probiotic drinks that are available in markets around the world is listed as a reference. The fermentability of carbon sources by probiotic microorganisms is crucial in addressing the development of plant-based drinks. Therefore, the pathway involved in metabolism of sucrose, glucose, fructose, and galactose in fruit and vegetable juice was also underlined. Finally, the key factors in monitoring the quality of probiotic products such as total soluble solids, sugar consumption, titratable acidity, pH, and stability at low storage temperatures were outlined.

RESUMEN

BACKGROUND: Current guidelines for the management of childhood wasting primarily focus on the provision of therapeutic foods and the treatment of medical complications. However, many children with wasting live in food-secure households, and multiple studies have demonstrated that the etiology of wasting is complex, including social, nutritional, and biological causes. We evaluated the contribution of household food insecurity, dietary diversity, and the consumption of specific food groups to the time to recovery from wasting after hospital discharge. METHODS: We conducted a secondary analysis of the Childhood Acute Illness Network (CHAIN) cohort, a multicenter prospective study conducted in six low- or lower-middle-income countries. We included children aged 6-23 months with wasting (mid-upper arm circumference [MUAC] ≤ 12.5 cm) or kwashiorkor (bipedal edema) at the time of hospital discharge. The primary outcome was time to nutritional recovery, defined as a MUAC > 12.5 cm without edema. Using Cox proportional hazards models adjusted for age, sex, study site, HIV status, duration of hospitalization, enrollment MUAC, referral to a nutritional program, caregiver education, caregiver depression, the season of enrollment, residence, and household wealth status, we evaluated the role of reported food insecurity, dietary diversity, and specific food groups prior to hospitalization on time to recovery from wasting during the 6 months of posthospital discharge. FINDINGS: Of 1286 included children, most participants (806, 63%) came from food-insecure households, including 170 (13%) with severe food insecurity, and 664 (52%) participants had insufficient dietary diversity. The median time to recovery was 96 days (18/100 child-months (95% CI: 17.0, 19.0)). Moderate (aHR 1.17 [0.96, 1.43]) and severe food insecurity (aHR 1.14 [0.88, 1.48]), and insufficient dietary diversity (aHR 1.07 [0.91, 1.25]) were not significantly associated with time to recovery. Children who had consumed legumes and nuts prior to diagnosis had a quicker recovery than those who did not (adjusted hazard ratio (aHR): 1.21 [1.01,1.44]). Consumption of dairy products (aHR 1.13 [0.96, 1.34], p = 0.14) and meat (aHR 1.11 [0.93, 1.33]), p = 0.23) were not statistically significantly associated with time to recovery. Consumption of fruits and vegetables (aHR 0.78 [0.65,0.94]) and breastfeeding (aHR 0.84 [0.71, 0.99]) before diagnosis were associated with longer time to recovery. CONCLUSION: Among wasted children discharged from hospital and managed in compliance with wasting guidelines, food insecurity and dietary diversity were not major determinants of recovery.

RESUMEN

Recent changes to the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) Cash-Value Benefit (CVB), which provides participants with money to spend on fruits and vegetables, have the potential to reduce disparities in healthy food access and food insecurity that were exacerbated by the COVID-19 pandemic. However, few studies have examined how the changes to the CVB allotment that occurred during the pandemic influenced WIC participants' perceptions of the benefit or their fruit and vegetable purchasing and consumption. To address this gap, we conducted semi-structured interviews with 51 WIC participants in Wilmington, Delaware. Survey measures included demographic questions, the Hunger Vital Sign food insecurity screener, and open-ended questions regarding perceptions of the CVB increase and its influence on participants' fruit and vegetable purchasing and consumption. Data were analyzed using a hybrid inductive and deductive coding approach. The results demonstrate that higher CVB allotments increased WIC participants' purchasing and consumption of fruits and vegetables, increased the frequency of their shopping occasions, and enhanced their dietary variety. Our findings also suggest that WIC participants highly value the increased CVB. Consequently, maintaining the increased CVB allotment could improve the nutritional outcomes of low-income mothers, infants, and children participating in WIC.

RESUMEN

Selenium is a trace element essential for the proper functioning of human body. Since it can only be obtained through our diet, knowing its concentrations in different food products is of particular importance. The measurement of selenium content in complex food matrices has traditionally been a challenge due to the very low concentrations involved. Some of the difficulties may arise from the abundance of various compounds, which are additionally present in examined material at different concentration levels. The solution to this problem is the efficient separation/preconcentration of selenium from the analyzed matrix, followed by its reliable quantification. This review offers an insight into cloud point extraction, a separation technique that is often used in conjunction with spectrometric analysis. The method allows for collecting information on selenium levels in waters of different complexity (drinking water, river and lake waters), beverages (wine, juices), and a broad range of food (cereals, legumes, fresh fruits and vegetables, tea, mushrooms, nuts, etc.).

RESUMEN

Geriatric depression, a chronic condition, has become a substantial burden in rural China. This study aimed to assess the association between dietary patterns and the risk of geriatric depression in rural China. Between March 2018 and June 2019, 3304 participants were recruited for this cross-sectional study in rural Tianjin, China. Principal component analysis was used to determine the major dietary patterns. The associations between dietary patterns and the risk of geriatric depression were assessed using a logistic regression model. Four dietary patterns were identified: vegetables-fruit, animal food, processed food, and milk-egg. The study found that vegetable-fruit (Q2 vs. Q1: OR = 0.62, 95% CI: 0.46-0.83; Q3 vs. Q1: OR = 0.54, 95% CI: 0.38-0.75; Q4 vs. Q1: OR = 0.39, 95% CI: 0.26-0.57) and animal food patterns (Q3 vs. Q1: OR = 0.69, 95% CI: 0.50-0.95; Q4 vs. Q1: OR = 0.58, 95% CI: 0.41-0.82) were associated with a decreased risk of depression, and inflammatory dietary pattern (Q2 vs. Q1: OR = 1.71, 95% CI: 1.23-2.38; Q3 vs. Q1: OR = 1.70, 95% CI: 1.22-2.36; Q4 vs. Q1: OR = 1.44, 95% CI: 1.03-2.03) was associated with an increased risk of depression. The present findings reinforce the importance of adopting an adequate diet consisting of vegetables, fruit and animal foods, while limiting the intake of pro-inflammatory foods, to decrease the risk of depression.

RESUMEN

Cardiovascular (CV) system dysfunction can result in the development of cardiovascular diseases (CVDs), a key cause of death around the world. For many people, the most common treatment choices are still based on various plants used in traditional and folk medicine. Interestingly, many of these plants demonstrate various biological activities and pro-health properties; as such, there has been growing scientific interest in their use as medicines, including treatments for CVDs. Due to their varied biological properties, including anti-inflammatory and anticancer potential, the members of the Asteraceae and Cucurbitaceae have long been used in traditional medicine. These properties are believed to derive from the chemical composition of the plants, which includes various flavonoids, phenolic acids, and terpenes. Although many of their pro-health properties have been well described, their effect on the cardiovascular system and CVDs remains unclear. The present work reviews the current literature about the effects of preparations of vegetables of the Asteraceae and Cucurbitaceae families on the cardiovascular system and CVDs. Various species from the two families demonstrate antioxidant and antiplatelet activities in vitro and in vivo, which play key roles in the prophylaxis and treatment of CVDs. Additionally, some species have been evaluated for their anticoagulant activity. This review also describes the biological properties of these vegetables and discusses their anti-hyperlipidemic action, and their potential for obesity prevention and body weight control.

RESUMEN

The education sector is recognised as an ideal platform to promote good nutrition and decision making around food and eating. Examining adolescents in this setting is important because of the unique features of adolescence compared to younger childhood. This systematic review and meta-analysis examine interventions in secondary schools that provide a routine meal service and the impact on adolescents' food behaviours, health and dining experience in this setting. The review was guided by Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Checklist and Cochrane Handbook recommendations. Studies published in English searched in four databases and a hand search yielded 42 interventions in 35 studies. Risk of bias was assessed independently by two reviewers. Interventions were classified using the NOURISHING framework, and their impact analysed using meta-analysis, vote-counting synthesis or narrative summary. The meta-analysis showed an improvement in students selecting vegetables (odds ratio (OR): 1.39; 1.12 to 1.23; p = 0.002), fruit serves selected (mean difference (MD): 0.09; 0.09 to 0.09; p < 0.001) and consumed (MD: 0.10; 0.04 to 0.15; p < 0.001), and vegetable serves consumed (MD: 0.06; 0.01 to 0.10; p = 0.024). Vote-counting showed a positive impact for most interventions that measured selection (15 of 25; 41% to 77%; p = 0.002) and consumption (14 of 24; 39% to 76%; p = 0.013) of a meal component. Interventions that integrate improving menu quality, assess palatability, accessibility of healthier options, and student engagement can enhance success. These results should be interpreted with caution as most studies were not methodologically strong and at higher risk of bias. There is a need for higher quality pragmatic trials, strategies to build and measure sustained change, and evaluation of end-user attitudes and perceptions towards intervention components and implementation for greater insight into intervention success and future directions (PROSPERO registration: CRD42020167133).

RESUMEN

BACKGROUND: Nutritional status affects the health of the public and is one of the key factors influencing social-economic development. To date, little research on the nutritional status of the Macao university student population has been conducted. OBJECTIVES: To identify and evaluate the dietary pattern and the nutritional intake among Macao university students. METHODS: The Macao students were selected by the stratified cluster random sampling method. A semi-quantitative food frequency questionnaire was used to investigate food consumption. Data were analyzed through a t-test and factor analysis by using SPSS Version 24.0. RESULTS: A total of 1230 questionnaires were distributed. From the respondents, 1067 (86.7%) were valid. In general, we identified three major dietary patterns in this population: (1) fruit and vegetable dietary pattern, characterized by abundant consumption of fruits and vegetables; (2) grain and high fat dietary pattern, characterized as high intakes of grains and animal foods; (3) high sugar dietary pattern, characterized by a large quantity of daily sugary drinks. The average daily intake of vitamin A, thiamine, calcium, and iodine were significantly lower than the Chinese Recommended Nutrient Intake (RNI) in the subjects. Conclusions: The dietary pattern of Macao students is similar to that of other Asians. Surprisingly, the daily intake of vitamin A, thiamine, calcium, and iodine by Macao university students is significantly lower than the Chinese RNI.

This cross-sectional study aimed to determine the associations between food groups and health-related quality of life (HRQoL). The data of 14,979 participants in the Korea National Health and Nutrition Examination Survey from 2016 and 2018 were examined. The HRQoL was assessed with EuroQol-5 Dimension. The 24-h recall test was used to examine the dietary intake of food groups. Males and females accounted for 13.79% and 21.62% of the low HRQoL groups. The males in the lowest tertile of the "vegetables" and "fish and shellfish" food groups were more likely to have a low HRQoL (odds ratio (OR), 95% confidence interval (CI) = 1.25 (1.05-1.65), 1.45 (1.12-1.89), respectively) than those in the highest tertile, whereas those in the lowest tertile of the "cereal and grain products" were less likely to have a low HRQoL (OR (95% CI) = 0.69 (0.52-0.91)). The females in the lowest tertile of the "vegetables" food group were more likely to have a low HRQoL (OR (95% CI) = 1.56 (1.17-3.01)) than those in the highest tertile. After adjusting for confounders indagated with not only dietary but also non-dietary factors such as stress, we found that low HRQoL was significantly associated with food groups of "vegetables", "fish and shellfish", and "cereal and grain products" among males and of "vegetables" among females.

RESUMEN

An ultrasound-assisted, one-pot cloud point extraction was developed for the determination of iron in vegetable samples by UV-Visible spectrophotometry. This method was based on the complexation of iron with an environmentally-friendly natural chelating agent extracted from Dipterocarpus intricatus Dyer fruit at pH 5.5 in the presence of Triton X-114. Reagent extraction, complexation, and preconcentration were performed simultaneously using ultrasound-assisted extraction at 45 °C. The surfactant-rich phase was diluted with ethanol and loaded through a syringe barrel packed with cotton that acted as a filter to trap the reagent powder. Analyte-entrapped on cotton was eluted using 0.1 mol·L-1 nitric acid solution. Filtrate and eluate solutions were measured absorbance of the dark-blue product at 575 nm. Influential parameters for the procedure were investigated. Under the optimum experimental conditions, the calibration curve was linear, ranging from 0.1 to 1.0 mg·L-1 with r2 = 0.997. Limits of detection and quantification were 0.03 and 0.09 mg·L-1, respectively while precision values of intra-day and inter-day were less than 5%. Recovery at 0.5 mg·L-1 ranged from 89.0 to 99.8%, while iron content in vegetable samples ranged from 2.45 to 13.36 mg/100 g. This method was cost-effective, reliable, eco-friendly, and convenient as a green analytical approach to determining iron content.
