RESUMO

INTRODUÇÃO: A percepção e satisfação corporal têm sido amplamente estudadas em diversos públicos, principalmente em estudantes universitários; porém, existem poucas investigações com vegetarianos, sendo assim, torna-se necessário avaliar se o padrão alimentar vegetariano está relacionado com os fenômenos inerentes à imagem corporal. OBJETIVO: Avaliar a percepção e a satisfação corporal entre estudantes universitários vegetarianos. MÉTODO: Trata-se de um estudo transversal com 123 participantes, no qual foram aplicados o Questionário de Imagem Corporal - BSQ (Body Shape Questionnaire) e a Escala de Silhuetas de Stunkard. RESULTADOS: Os dados mostraram que 86,2% dos participantes eram eutróficos (IMC=22,4±3,3), sendo o score obtido no BSQ foi de 84,6 pontos (±36,0) correspondente à leve insatisfação com a imagem corporal. Cerca de 82,1% dos estudantes se mostravam insatisfeitos com a silhueta, dentre estes, 61,4% desejavam diminuí-la. CONCLUSÃO: O padrão alimentar (ovolactovegetariano, lactovegetariano, vegetariano estrito e vegano) não se relacionou com a insatisfação corporal, mas sim o desejo de ter silhuetas magras que são valorizadas pelo padrão de beleza vigente.

INTRODUCTION: For Body perception and satisfaction have been widely studied among different publics, especially among college students; however, there are few investigations with vegetarians. Therefore, it is necessary to evaluate whether the vegetarian eating pattern is related to the phenomena inherent to body image. OBJECTIVE: To evaluate body perception and body satisfaction among vegetarian college students. METHOD: This is a cross-sectional study with 123 participants, in which the Body Image Questionnaire (BSQ) and the Stunkard Silhouette Scale were applied. RESULTS: The data showed that 86.2% of the participants were eutrophic (BMI=22.4±3.3), and the score obtained in the BSQ was 84.6 points (±36.0) corresponding to a mild dissatisfaction with body image. About 82.1% of the students were dissatisfied with their silhouette, and 61.4% of them wanted to reduce it. CONCLUSION: Dietary patterns (ovolactovegetarian, lactovegetarian, strict vegetarian, and vegan) were not related to body dissatisfaction, but rather the desire to have thin silhouettes that are valued by the prevailing beauty standard.

RESUMO

En la actualidad cada vez más familias optan por seguir una alimentación basada en plantas (ABP). Es fundamental que pediatras y agentes de salud conozcan estos tipos de patrones alimentarios para asesorar adecuadamente a sus pacientes y derivarlos oportunamente a especialistas capacitados con el objetivo de garantizar un adecuado crecimiento y desarrollo principalmente en la edad pediátrica, evitando posibles consecuencias negativas sobre la salud. La mayoría de las sociedades científicas del mundo considera a las dietas vegetarianas apropiadas para todas las etapas de la vida si están correctamente planificadas, suplementadas y con un seguimiento adecuado por especialistas capacitados. Con respecto a las dietas veganas existen controversias por parte de las distintas sociedades con respecto a si son adecuadas o no en pediatría. Recientemente se han revisado las descripciones respecto a las tipificaciones de una ABP y se ha propuesto una definición estándar de estos tipos de dieta. Los riesgos más significativos asociados a la mala planificación de estas dietas son las deficiencias de calcio, vitamina D y vitamina B12, aunque también se debe tener en cuenta el estado del zinc, selenio, yodo y los ácidos grasos Omega 3. Es importante la planificación diaria de un plato nutricionalmente completo y es incuestionable que quienes siguen estos patrones alimentarios reciban suplementos con vitamina B12 adecuados para cada etapa de la vida. Se requieren más estudios en pediatría para evaluar los efectos de las distintas ABP sobre la ingesta de nutrientes, el estado nutricional, el crecimiento, desarrollo y la prevención de enfermedades no transmisibles (AU)

Currently, an increasing number of families are choosing to follow a plant-based diet (PBD). It is essential that pediatricians and healthcare agents know these types of dietary patterns in order to properly advise their patients and refer them to trained specialists to ensure adequate growth and development, especially in the pediatric age, avoiding possible negative health consequences. Most of the world's scientific societies consider vegetarian diets appropriate for all stages of life if they are adequately planned, supplemented and monitored by trained specialists. However, there is controversy among different societies regarding the appropriateness of vegan diets for children. Recently, there has been a review of descriptions concerning the characteristics of a plant-based diet, leading to a proposed standard definition for these types of diets. The most significant risks associated with poorly planned diets are calcium, vitamin D, and vitamin B12 deficiencies, although zinc, selenium, iodine and omega-3 fatty acid status should also be considered. The daily planning of a nutritionally complete meal is important and it is imperative that those who follow these dietary patterns receive vitamin B12 supplementation appropriate for each stage of life. Further studies in children are needed to evaluate the effects of different PBDs on nutrient intake, nutritional status, growth, development, and prevention of noncommunicable diseases (AU)

RESUMO

Diet therapy in conservative treatment of chronic kidney disease involves protein restriction, but there is not enough evidence to recommend a particular type of protein, whether animal or plant based. However, studies suggest that plant-based diets help reduce the consumption of total and animal protein, reduce the need for nephroprotective drugs, improve complications and bring advantages in terms of disease progression and patient survival. The article considers up-to-date data on the effects of this diet and observed that when low in protein, primarily vegetable and in some cases supplemented with ketoanalogues, it can result in positive clinical outcomes, such as: delay in the decrease in the glomerular filtration rate, lower concentrations of urea, reduction of serum creatinine and phosphorus concentrations, lower metabolic acidosis, higher insulin sensitivity and lower systemic inflammation. As a whole, this dietary pattern may be able to postpone the start of dialysis with less progression of renal insufficiency. Additional research is needed to better characterize this dietary pattern.

La dietoterapia en el tratamiento conservador de la enfermedad renal crónica implica la restricción de proteínas, pero aún no hay pruebas suficientes para recomendar un tipo concreto de proteínas, ya sean animales o vegetales. Sin embargo, los estudios sugieren que las dietas basadas en plantas ayudan a reducir la ingesta de proteínas totales y animales, disminuyen la necesidad de fármacos nefroprotectores, mejoran las complicaciones y presentan ventajas con respecto a la progresión de la enfermedad y la supervivencia de los pacientes. En este artículo se consideran datos actualizados sobre los efectos de esta dieta y se observa que, cuando es hipoproteica, principalmente vegetal y en algunos casos se complementa con cetoanálogos, puede dar lugar a resultados clínicos positivos, como una disminución retardada de la tasa de filtración glomerular, concentraciones más bajas de urea, concentraciones reducidas de creatinina y fósforo séricos, menor acidosis metabólica, mayor sensibilidad a la insulina y menor inflamación sistémica. En conjunto, este patrón dietético tiene el potencial de retrasar el inicio de la diálisis con una menor progresión de la insuficiencia renal. Es necesario seguir investigando para caracterizar mejor este patrón dietético.

RESUMO

The continuous biomonitoring of a population directly or indirectly exposed to pesticides could be an additional tool for decision makers to improve their health conditions. In this work, we performed biomonitoring on two groups of people from the Mexicali Valley who were continuously exposed to pesticides using the cytokinesis-block micronucleus cytome assay (L-CBMN) to evaluate cytotoxic and genotoxic damage in human peripheral blood lymphocytes. The study groups comprised 14 indigenous Cucapah with non-vegetarian habits (NV group) from Ejido el Mayor (32.12594°, -115.27265°) and 21 lacto-ovo vegetarian (LOV) persons from the Seventh-day Adventist Church of Ejido Vicente Guerrero (32.3961°, -115.14023°). The L-CBMN assay determines the nuclear division index (NDI), apoptosis, necrosis, micronuclei (MNs), nuclear buds (NBUDs), and nucleoplasmic bridges (NPBs). Our results show that, regardless of diet or daily habits, both the studied groups presented with cytogenotoxic damage compared with non-exposed pesticide individuals, without modifications to the nuclear division index. In the rest of the evaluated biomarkers, the NV group exhibited greater cytotoxic and genotoxic damage than the LOV group. Nevertheless, individuals practicing a lacto-ovo vegetarian diet (LOV) showed lower damage than those with non-vegetarian habits (NV), suggesting a better antioxidant response that helps decrease the genotoxic damage due to the enhanced intake of folates and antioxidants from a plant-based diet.

RESUMO

Atherosclerosis, chronic non-communicable diseases, and metabolic syndrome are highly interconnected and collectively contribute to global health concerns that reduce life expectancy and quality of life. These conditions arise from multiple risk factors, including inflammation, insulin resistance, impaired blood lipid profile, endothelial dysfunction, and increased cardiovascular risk. Adopting a plant-based diet has gained popularity as a viable alternative to promote health and mitigate the incidence of, and risk factors associated with, these three health conditions. Understanding the potential benefits of a plant-based diet for human health is crucial, particularly in the face of the rising prevalence of chronic diseases like diabetes, hypertension, dyslipidemia, atherosclerosis, and cancer. Thus, this review focused on the plausible advantages of consuming a type of food pattern for the prevention and/or treatment of chronic diseases, emphasizing the dietary aspects that contribute to these conditions and the evidence supporting the benefits of a plant-based diet for human health. To facilitate a more in-depth analysis, we present separate evidence for each of these three concepts, acknowledging their intrinsic connection while providing a specific focus on each one. This review underscores the potential of a plant-based diet to target the underlying causes of these chronic diseases and enhance health outcomes for individuals and populations.

RESUMO

BACKGROUND: Psoriasis is a chronic inflammatory disease associated with systemic inflammation and comorbidities. Changes in the composition of the intestinal microbiome are involved in the pathogenesis of inflammatory diseases and metabolic syndrome. Characterizing the intestinal microbiome of patients with psoriasis may be relevant for the understanding of its clinical course and comorbidity prevention. OBJECTIVE: To characterize the intestinal microbiome of men with psoriasis compared to omnivore and vegetarian controls (without psoriasis). METHOD: Cross-sectional study of 42 adult males: 21 omnivores with psoriasis; and controls: 14 omnivores and 7 vegetarian individuals. The characterization of the intestinal microbiome was performed by metagenomic analysis. Serum levels of lipopolysaccharide-binding protein (LPB) and C-reactive protein (CRP) were evaluated. RESULTS: The groups differed from each other regarding nutritional aspects and microbiome; individuals with psoriasis had a higher consumption of protein and lower consumption of fibers. Levels of LPB, CRP, and the Firmicutes/Bacteroidetes ratio were higher in the group with psoriasis than in the vegetarian group (p<0.05). The genera Prevotella, Mogibacterium, Dorea, Bifidobacterium and Coprococcus, differed in the group with psoriasis compared to vegetarians; the genera Mogibacterium, Collinsella and Desulfovibrio differed from omnivores. A microbiome pattern linked to psoriasis (plsPSO) was identified, which was associated with higher LPB levels (rho=0.39; p=0.02), and lower dietary fiber intake (rho=-0.71; p<0.01). STUDY LIMITATIONS: Only adult men were evaluated. CONCLUSION: A difference was identified in the intestinal microbiome of adult men with psoriasis when compared to healthy omnivores and vegetarian controls. The identified microbiome pattern was correlated with dietary fiber intake and serum levels of LPB.

RESUMO

Diferentes estudios han relacionado el nivel socioeconómico con la calidad de la dieta y la prevalencia de riesgo de deficiencia de nutrientes. En personas vegetarianas, cuando no se sigue una dieta adecuada, existe la posibilidad de tener una baja ingesta de ciertos nutrientes, principalmente de vitamina B12, vitamina D, calcio, hierro, zinc, ácidos grasos omega-3 y proteínas. Este estudio tiene como objetivo evaluar la ingesta dietética en personas vegetarianas según su nivel socioeconómico en una región de Colombia. Los participantes completaron un cuestionario en el cual se les preguntó por variables socioeconómicas, antropométricas y la frecuencia de consumo de 48 alimentos y suplementos. Posteriormente, a un subgrupo de la muestra se le realizaron dos recordatorios de 24 horas en diferentes días de la semana. Se encontró que, a menor nivel socioeconómico, hay un menor consumo de lácteos, cereales integrales, frutas y verduras. Así mismo, se observó que según el tipo de vegetarianismo hay diferencias en el consumo de cobalamina, fibra y calcio. Se concluye que, de manera similar a los omnívoros, se requiere de educación nutricional para mejorar la elección de los alimentos y lograr suplir los requerimientos nutricionales, independientemente del nivel económico.

Different studies have related socioeconomic status to diet quality and the prevalence of nutrient deficiency risk. Among vegetarians, when an adequate diet is not followed, there is a possibility of having a low intake of certain nutrients, mainly vitamin B12, vitamin D, calcium, iron, zinc, omega-3 fatty acids and proteins. This study aims to evaluate the dietary intake of vegetarians according to their socioeconomic level in a region of Colombia. Participants completed a questionnaire in which they were asked about socioeconomic and anthropometric variables and the frequency of consumption of 48 foods and supplements. Subsequently, a subgroup of the sample was given two 24-hour reminders on different days of the week. We found that the lower the socioeconomic level, the lower the consumption of dairy products, whole grains, fruits and vegetables. Likewise, it was observed that depending on the type of vegetarianism, there are differences in the consumption of cobalamin, fiber and calcium. We conclude that, similar to omnivores, nutritional education is required to improve the choice of foods and to meet nutritional requirements, regardless of economic level.

RESUMO

PURPOSE: This paper aims to present an overview of the definitions of "plant-based and "vegetarian diets" adopted by different organizations worldwide, proposing new standard definitions and discussing the notion of vegetarianism as a restrictive dietary pattern. METHODS: An extensive literature review on the different definitions of vegetarian and plant-based diets was conducted. Definitions of different international vegetarian and vegan organizations were also taken into account. Objective definitions for vegetarian and plant-based diets, as well as for their subcategories, were proposed. Other aspects related to how vegetarian diets are viewed and defined were also discussed. RESULTS: We proposed that a vegetarian diet should be defined as "a dietary pattern that excludes meat, meat-derived foods, and, to different extents, other animal products". This definition would include, among others, ovolactovegetarian and vegan diets. The proposed definition for a plant-based diet was "a dietary pattern in which foods of animal origin are totally or mostly excluded". Other types of diets, such as flexitarian and pescetarian diets, could be considered plant-based. A vegetarian diet should not be considered restrictive. Instead, terms such as alternative or non-conventional could be used to define it and to distinguish it from the conventional diet adopted by most of the Western population. CONCLUSION: This paper was able to elaborate objective definitions of vegetarian and plant-based diets. Standardizing nomenclatures may reduce misinterpretation and confusion in this field of study.

RESUMO

Interest in plant-based diets and vegetarianism is increasing worldwide, however, a concern for total vegetarians is vitamin B12 (B12) deficiency. We conducted a systematic review to investigate non-animal food sources of B12. Databases were PubMed, LILACS, Cochrane, Embase and Google Scholar, up to September 9, 2020. Quality of the eligible studies were assessed. We identified 25 studies which assessed B12 content in seaweeds, mushrooms, plants and fermented foods. Initial studies were microbiological bioassay, ELISA and HPLC. In the last decade, more sensitive method for real B12 determination was used, the liquid chromatography-electrospray ionization tandem mass spectrometry chromatograms. Real B12 content varied from mean (SD) mcg/portion size of seaweed hijiki 3 × 10-3/7 g to nori 1.03 - 2.68/sheet; mushroom white button cap 2 × 10-3(7 × 10-4)/20 g dry weight (dw) to shiitake 0.79(0.67)-1.12 (0.78)/20 g dw; and fermented foods from soy yogurt 20/cup. It is possible that daily recommendations for B12 can be met by a varied diet containing non-animal B12 food sources. Future research should consider different methods of storage, preparation, fermented foods and standardization of the production of certain foods.Supplemental data for this article is available online at https://doi.org/10.1080/10408398.2022.2053057.

RESUMO

BACKGROUND: The association between vegetarianism and depression is still unclear. We aimed to investigate the association between a meatless diet and the presence of depressive episodes among adults. METHODS: A cross-sectional analysis was performed with baseline data from the ELSA-Brasil cohort, which included 14,216 Brazilians aged 35 to 74 years. A meatless diet was defined from in a validated food frequency questionnaire. The Clinical Interview Schedule-Revised (CIS-R) instrument was used to assess depressive episodes. The association between meatless diet and presence of depressive episodes was expressed as a prevalence ratio (PR), determined by Poisson regression adjusted for potentially confounding and/or mediating variables: sociodemographic parameters, smoking, alcohol intake, physical activity, several clinical variables, self-assessed health status, body mass index, micronutrient intake, protein, food processing level, daily energy intake, and changes in diet in the preceding 6 months. RESULTS: We found a positive association between the prevalence of depressive episodes and a meatless diet. Meat non-consumers experienced approximately twice the frequency of depressive episodes of meat consumers, PRs ranging from 2.05 (95%CI 1.00-4.18) in the crude model to 2.37 (95%CI 1.24-4.51) in the fully adjusted model. LIMITATIONS: The cross-sectional design precluded the investigation of causal relationships. CONCLUSIONS: Depressive episodes are more prevalent in individuals who do not eat meat, independently of socioeconomic and lifestyle factors. Nutrient deficiencies do not explain this association. The nature of the association remains unclear, and longitudinal data are needed to clarify causal relationship.
