Introduction: The use of vegetable proteins as ingredients in food systems is based on their functional properties. The water and oil holding capacity, foaming, and emulsifying capacity/stability, and antioxidant assay of the protein fractions - albumins, globulins 7S/11S, glutelins and prolamins - isolated from Leucaena seed were evaluated. Objective: The objective of this study was to evaluate the functional properties and antioxidant capacity of the concentrate and protein fractions of ripe Leucaena spp. seeds. Materials and methods: Ripe Leucaena seeds were collected and evaluated in Oaxaca, Mexico (16°59’21’’N 96°43’26’’O) during the months of February-April 2021.The protein concentrate was isolated by isoelectric precipitation (pH=9, pH=4). The albumins, globulins, glutelins and prolamins were isolated based on their solubility properties in different extracting solutions. Results: Glutelins constituted the main protein fraction (75.88%). Prolamins were not found. The glutelins fractions showed the highest oil holding capacity (0.93±0.08 mL g-1). The albumins fraction had the highest water holding capacity (2.53±0.15 mL g-1), foaming capacity and foam stability (71.83±1.26 % and 70.00±0.00%, respectively) and antioxidant capacity (18.09±0.88%). The globulins exhibited the highest emulsifying capacity and emulsion stability (56.83±1.76% and 55.67±1.20%, respectively). Conclusions: The concentrate and protein fraction of Leucaena seeds showed different techno-functional and antioxidant properties of interest for the food industry, like those showed by other commercial vegetable proteins.

Introduction: vegetarian diets are diets that avoid animal meat, it includes ovolactovegetarian and vegan diets, among other plant-based variants. Objective: to characterize food consumption, anthropometric nutritional assessment, physical activity level and motivations in a sample of vegetarian adults from the Capital District, Yaracuy and Carabobo states of Venezuela. Materials and methods: 51 adults were evaluated, 23.5% vegan and 76.5% ovo-lacto vegetarian, aged between 18 and 65 years. A 24-hour dietary recall was carried out, indicators of dimension (BMI and waist circumference) and body composition (muscle area and percentage of fat) were taken, the long IPAQ instrument of physical activity was applied and it was asked about the main motivation to follow these diets. Results: the diet was deficient in calories (60.8%), low in carbohydrates (72.5%) and fats (58.8%), and high in proteins (43.1%) and dietary fiber (70.6 %). The anthropometric nutritional assessment of the individuals resulted in an adequate weight (62.7%), average muscularity (51%) and fat (68.6%), and low risk according to waist circumference (86.3%). The level of physical activity that prevailed were the moderate and intense categories with 39.2% each. The majority decided to follow the vegetarian diet for health reasons 72.5%. Conclusions: the majority of the study group, despite having an unbalanced diet (low in carbohydrates and fats, but high in proteins and fiber), presented an anthropometric nutritional status and levels of physical activity within acceptable ranges

Introduction: Rice is a staple food in Costa Rica representing almost 24 % of the total calorie intake in the diet. Consumers have become more quality conscious about the rice consumed, so producers need to focus on the quality of rice along with production. Objective: The aim of this study was to investigate the physicochemical profile and consumer preference of five Costa Rican rice varieties: Palmar 18, Basmatico, Chin Chin, INTA-Miravalles, and CR- 5272. Materials and methods: Proximate analysis, amylose, and mineral content were performed in the raw grain. Two different sessions were performed (n=120 each) to evaluate consumer preference measurements using the John Brown R-Index (RJB) index. The first sensory panel selected the best cooking preparation and the second, the preferred rice variety. Instrumental color measurements (L*, C*, hº, DE) were applied to the cooked rice varieties (76-96ºC for 38 min). Results: Regarding the physicochemical characterization, INTAMiravalles showed the highest protein content (8.2%), while Basmatico and Chin Chin, the lowest. Four varieties presented high amylose content (AC) and INTA-Miravalles reported an intermediate AC. The mineral content varied among varieties. INTA-Miravalles showed the highest N, followed by Palmar 18. The cooking preparation from the regulatory agency was preferred by consumers. The consumers’ preference of the varieties ranked from high to low: Basmatico>Chin Chin=CR5772>Palmar 18=INTA-Miravalles. Conclusions: This study suggests that consumer preference for cooked rice was influenced by physicochemical characteristics such as protein, AC, mineral content, and aromatic attributes. Consumer acceptance is an important factor to consider when new varieties are developed. The water-to-rice ratio during cooking played an important role in cooked rice sensory quality.

The green tea catechins (Camellia sinensis) (CTV) have beneficial effects for health associated with their antioxidant potential. Moreover, oxidative stress is one of the pathways for inducing genotoxic damage. Hence, in this review, an analysis of the antigenotoxic and genotoxic effects of CTV was carried out, emphasizing the pathways involved in these processes and their effects on health. A review of articles indexed in the PubMed® and ScienceDirect® (2021) databases with the keywords “green tea” and “green tea catechins” was carried out. Studies were delimited using the Boolean operators “AND”, “OR” and “NOT” (“antigenotoxic”, “genotoxic”, “antioxidant” and “prooxidant”). For the most part, publications from 2016 to 2021 were considered. It was observed that the beneficial health effects of CTVs are related to: a) their antioxidant activity through the capture, inhibition and prevention of the formation of reactive oxygen species; b) the regulation of the endogenous antioxidant system; c) the activation of the repair mechanisms by contributing to the elimination of the 8-hydroxy-2'-deoxyguanosine adduct; d) the induction of apoptosis in cells with DNA damage; and e) the inhibition of inflammation related to its antiapoptotic activity. Although some of the studies reported genotoxic effects, these in turn contributed to the elimination of cells with genetic damage. Therefore, the genotoxic activity of CTV cannot be considered as harmful to health.

In 2009, a food classification was proposed, called NOVA classification. Latin American countries have stood out in their use in nutritional recommendations and regulatory agenda. Objective. To evaluate how scientific production in food and nutrition in Latin America has incorporated the NOVA classification. Materials and methods. The analysis of scientific production was carried out from annals at the Latin American Congress of Nutrition (SLAN) in 2012, 2015 and 2018. The terms used for the search were: NOVA, ultra-processed, processed, processing and food guide, in Portuguese, English and Spanish. After the search, the exclusion and inclusion criteria were applied and the selected abstracts were described according to previously defined analytical variables. Results. A total of 153 were analyzed, 24 of which were published in 2012, 20 in 2015 and 109 in 2018. Most studies were carried out in Brazil (56,2%), followed by Mexico (12,4%) and involved adolescents (28,8%), adults (21,6%) and food (19,6%) as subject or unit of analysis. Most of the works were classified in the area of Public Health Nutrition (88,9%), were observational (82,3%) and used a quantitative method (76,5%). The sale and/or consumption of food (46,4%) and the food environment (24,2%) were the most common objects of study. Conclusion. The scientific production that considers the NOVA classification in Latin America increased in 2018, with Brazil and Mexico leading the development of studies. Studies that explore the relationship of NOVA classification to food price, culinary skills and public policy analysis are research opportunities.

The obesity worldwide has produced an increase in obesity-related diseases and can be associated with low concentrations of 25-hydroxyvitamin-D. Also obesity and low physical activity can decrease sun exposure, so the aim was to correlate vitamin D intake with serum 25-hydroxyvitamin-D levels and to assess sun exposure habits in schoolchildren with obesity. Materials and methods. A correlational study was performed from January 2017 to January 2018 on 103 children between 6-12 years of age, with a body mass index ≥+2SD for age and sex, according to the World Health Organization. Blood samples were taken to determine the serum concentrations of 25-hydroxyvitamin-D, a nutritional survey to determine the vitamin D intake and a sun exposure questionnaire were applied. A Spearman correlation coefficient analysis was performed. Results. Forty-seven percent of the children were girls. The median years of age was 10. The median serum 25-hydroxyvitamin-D levels were 35.5 ng/mL, 74.8% had sufficient levels, 25.2% had insufficient levels. The median vitamin D intake was 214.7IU in boys and 231.9IU in girls. Regarding sun exposure, most of the children had excessive levels of sun exposure and inadequate sun protection practices. A positive correlation between vitamin D intake and serum 25-hydroxyvitamin-D was identified only in boys (rho=0.276, p=0.041). Conclusion. A positive correlation between vitamin D intake and serum 25-hydroxyvitamin-D levels was found in obese boys and excessive levels of sun exposure with inadequate sun protection practices in boys and girls.

At present, education in Health Sciences requires interaction with real patients, which is made more complex due to the need to ensure their health safety. For this reason, new teaching methodologies are now being implemented, which help to improve and protect safe care. Objective: This study was carried out using a quantitative approach with a non-experimental, descriptive design. Materials and Methods: The sample was non-probabilistic and consisted of 87 undergraduate students. A questionnaire was used, with 18 statements divided into 3 dimensions: dimension 1, simulation structure, with six questions reflecting aspects related to its implementation; dimension 2, learning, with seven questions related to aspects of effective communication, trust, learning and respect for diversity; dimension 3, feedback for learning, with five questions, including feedback by the teacher and the simulated patient, as well as their own views with regard to participating in another similar experience again. A five-point Likert scale was used. Results: The three dimensions studied, simulation structure, learning and feedback for learning, report a high level of positive perceptions. Conclusion: The simulation strategy is an educational tool in health-related careers that enhances the clinical competencies of the students as well as the relevant theoretical and practical skills and abilities in their learning process, promoting integration of the knowledge acquired in previous subjects.

Conclusion: The simulation strategy is an educational tool in health-related careers that enhances the clinical competencies of the students as well as the relevant theoretical and practical skills and abilities in their learning process, promoting integration of the knowledge acquired in previous subjects.","PeriodicalId":8390,"journal":{"name":"Archivos Latinoamericanos De Nutricion","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43714553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
The investigations carried out during the last century related to the description of the Gut Microbiota (GM) suggest a concrete relationship between its composition and the health of the host. Its deregulation called intestinal dysbiosis has been associated with different types of gastrointestinal, metabolic, oncological and even psychiatric diseases. Numerous reports that have described the condition of dysbiosis in obesity stand out, both in animal and human models of different age groups and regions of the world. In turn, the composition of the microbiome has also been associated with the different comorbidities of obesity, postulating that MI has an influence on adipose tissue (AT) dysfunction, understanding that it corresponds to the main modulator of the pathogenesis of obesity. However, it is not yet possible to establish a plausible mechanistic explanation. Currently, the use of multi-omics technologies, together with the evaluation of physiological variables, could provide us with a better understanding of the question raised. In view of this, this review aims to review the latest advances in understanding the influence of the intestinal microbiota on AT and its contribution to the mechanisms related to the pathogenesis of obesity. Among the main mechanisms identified, the evidence reports physiological links between the composition of GM and the modulation of inflammation, intestinal permeability and adipogenesis. The pathways involved derive from the influence of intestinal dysbiosis on the action of short-chain fatty acids, claudins, macrophages, oligosaccharides, among others. The mechanisms involved, mainly studied in animal models, should be considered for evaluation in future longitudinal and experimental studies in humans in order to obtain a better understanding of the implication of each mechanism in the global pathogenesis of obesity.

During pregnancy, omega 3 supplementation has raised its popularity due to evidence that it would show not only benefits in the neural and visual development of the unborn child, but also in the prevention of obstetrical pathologies associated with of perinatal morbidity and mortality. Omega 3 polyunsaturated fatty acids (PUFAs), specifically, docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), possess anti-inflammatory, vasodilatory and anti-aggregating properties, which have led to the use of PUFAs in the prevention of cardiovascular diseases. In this review, we detail the effects of omega 3 supplementation on different aspects of pregnancy such as prevention of preterm birth, pre-eclampsia, postpartum depression, and improved metabolism during gestational diabetes. Although there are several randomized clinical trials using omega-3 supplementation during pregnancy, the evidence remains inconclusive, due to variability in dosage and administration time. Certainly, a greater number of high-quality studies including randomized clinical trials are necessary to determine the impact of omega 3 supplementation during pregnancy in the prevention of obstetric pathologies.
