RESUMO

Mental well-being is conditioned by several factors, including religious involvement and diet. However, this evidence does not exist among members of the Seventh-day Adventist Church (SDA) in Latin America, particularly Peru. This study evaluated the association between religious involvement and vegetarian diet with mental well-being in members of the SDA Church in Peru. In this cross-sectional study, the sample included 767 participants, aged 18 to 59 years. A face-to-face and online survey was administered that included information on the dietary regimen and sociodemographic characteristics. Religious involvement and mental well-being were measured using the 12-item version of the General Health Questionnaire (GHQ-12) and the Duke University Religion Index (DUREL), respectively. A multivariate analysis was conducted to investigate the factors associated with mental well-being. Being female (ß = 1.80, p < 0.001), coming from the highland region (ß = 1.98, p < 0.001), having a basic educational degree (ß = 1.85, p < 0.001), a higher level of religious involvement (ß = 0.34, p < 0.001), and being vegetarian (ß = 1.21, p < 0.001) were associated with greater mental well-being. This evidence highlights the implication of religious participation and a vegetarian diet in mental health, not only among SDA church members but also in a broader context. However, it should be recognized that direct transfer of church-based health promotion interventions and strategies to the general population can present challenges; therefore, it is suggested that these strategies should be adapted and adjusted to consider differences in the community context.

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

PURPOSE OF REVIEW: Bone fractures can have a devastating effect on health, especially in the elderly, undermining their independence for daily activities, and increasing the risk of comorbidities and mortality. Nutrition is a key factor in maintaining an optimal bone health across the lifespan. The number of people that choose to avoid meat or even all animal products is increasing globally, for a diversity of reasons. Properly planned vegetarian and vegan diets are widely recognized as a healthy dietary pattern, but the long-term impact of these diets on bone health and more specifically risk of bone fractures is less clear. Classic studies have observed a slightly lower bone mineral density in vegetarians but have many limitations, including inadequate adjusting for relevant confounding factors, and cross-sectional design. The aim of this review is to summarize and put into context the current evidence on the effect of vegetarian and vegan diets on bone health, with a focus on fracture risk. RECENT FINDINGS: In recent years, results from many large prospective studies have emerged, which allowed us to assess the risk of incident bone fractures in vegetarians. In these studies, vegetarian and especially vegan diets were associated with an increased risk of bone fractures. In many recent prospective cohort studies, vegetarian and especially vegan diets were associated with an increased risk of bone fractures. At least part of this risk could be due to a lower body mass index and a lower intake of nutrients such as calcium, vitamin D, and protein. Some evidence suggests that combined vitamin D and calcium supplementation and other factors such as consumption of protein-rich foods may attenuate this risk. The eventual deleterious effect of vegetarian diets on bone health should be contextualized and balanced with its benefits, such as lower risk of cardiovascular disease and cancer.

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 nutrient composition of plant-based burgers is a key factor when making their purchase/consumption decision to maintain a balanced diet. For this reason, ingredient list and nutritional information of burgers launched in the global market were retrieved from their labels. Products were classified based on the technology development, market position and region of the manufacturer. From the ingredient analysis, we observed a high heterogeneity in the ingredients used, a predominance of soy and wheat as main sources of proteins, and the increasing use of new protein sources (e.g. peas, other types of beans and pseudo-cereals). Oil was the most cited ingredient followed by salt. Nutritional composition varied mainly depending on the region with no clear pattern among countries. To less extent, technology development resulted in traditional products with lower amounts of protein and higher amounts of carbohydrates. Vegan and vegetarian products showed limited differences due to the high intra-heterogenicity.

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

INTRODUCTION: There is a growing interest in vegetarian and vegan diets, but both can potentially affect tissue fatty acids (FA) composition. We aimed to evaluate the effect of vegetarian diets on plasma, erythrocytes, and sperm n-3 polyunsaturated fatty acids (n-3 PUFA) status in healthy young men. METHODS: Four groups were studied: i) men consuming a regular omnivore diet (OMV-1, n = 35); ii) men consuming an omnivore diet but excluding fish and seafood (OMV-2, n = 34); iii) men consuming a pescetarian diet (including dairy, eggs, fish, and seafood) (PESC, n = 36); and iv) men following a strict vegan diet (VEG, n = 35). Participants in each group should follow their diet for at least the previous 12 months. Diet evaluation used a structured validated food frequency questionnaire. FA composition was measured in plasma, erythrocyte phospho-lipids, and spermatozoa by gas-liquid chromatography, expressed as a mole percentage of the total FA content. RESULTS: Main findings showed higher alpha-linolenic fatty acid (ALA) and total n-3 PUFA dietary intake in the VEG group. In plasma, arachidonic and eicosapentaenoic acids were higher in OMV and PESC groups, whereas docosahexaenoic acid (DHA) level was lower in VEG. Higher ALA, but reduced DHA and total n-3 PUFA levels were found in erythrocytes and spermatozoa in the VEG group. CONCLUSION: Higher dietary ALA intake was found in pescetarians and vegan men. However, the higher ALA intake was not reflected in higher DHA content in the evaluated tissues. PUFA assessment, with particular emphasis in DHA, are necessary to improve PUFA status in vegan men.

RESUMO

Resumen Introducción: recientemente, se ha evidenciado gran desarrollo de variados productos destinados a la población vegetariana/vegana. Sin embargo, su valor nutricional no ha sido estudiado en profundidad. El objetivo del presente estudio fue evaluar aporte potencial (AP) y porcentaje de cobertura de requerimientos diarios (%RD) de hierro, calcio y zinc de alimentos dirigidos a poblaciones adolescente y adulta vegetariana/vegana. Materiales y método: se analizaron cinco medallones (4 comerciales, 1 casero) y once bebidas (9 comerciales, 4 de ellas c/jugo frutal y 2 caseras) elaborados con materias primas vegetales. Se estableció el AP de Fe, Ca y Zn en los productos considerando su contenido y dializabilidad porcentual (D%). Se calculó, para una porción de alimento, el porcentaje de cobertura del requerimiento diario de estos minerales. Resultados: el contenido de los minerales en los medallones fue: [Fe] 1,64-4,21 mg%; [Ca] 104-213 mg% y [Zn] 0,53-3,57 mg%; en las bebidas se observó: [Fe] 0,24-2,39 mg%; [Ca] 71-214 mg% y [Zn] 0,18-0,79 mg%. La D% en medallones fue: Fe 7,3-11,9; Ca 10,2-18,2 y Zn 17,0-21,4 y para las bebidas, Fe 5,2-32,8; Ca 6,4-35,7 y Zn 5,9-33,9. El %RD para adolescentes, considerando una porción de medallones fue: Fe mujeres 3,0-9,0%; hombres 5,0-16%; Ca 0,7-6,8% y Zn 1,5-3,9% y para adultos fue: Fe mujeres 3,0-10%; hombres 7,0-20%; Ca 0,6-5,8% y Zn 2,0-5,1%. Al considerar las bebidas, el %RD para adolescentes fue: Fe mujeres 2,0-28%; hombres 4,0-53%; Ca 0,4-22% y Zn 1,3-9,5%. Para adultos fue: Fe mujeres 2,0-31%; hombres 5,0-64%; Ca 0,3-19% y Zn 1,8-12%. Conclusiones: en los medallones se observó bajo %RD para los minerales estudiados. Las bebidas con agregado de jugos de naranja o manzana aportaron cantidades significativas de hierro. El %RD para zinc y calcio de los dieciséis alimentos fue bajo (ambos grupos estudiados). Consecuentemente, para cubrir los requerimientos de estos minerales habría que combinar adecuadamente los alimentos que se consumen.


Abstract Introduction: recently, there has been great development of various products aimed at the vegetarian/vegan population. However, its nutritional value has not been studied in depth. The objective of this study was to evaluate potential intake (PI) and percentage of coverage of daily requirements (% RD) of iron, calcium and zinc from foods aimed at adolescent and adult vegetarian/vegan populations Materials and method: five medallions (4 commercial, 1 homemade) and eleven beverages (9 commercial, 4 of them with fruit juice and 2 homemade) made with vegetable raw materials were analyzed. The PI of Fe, Ca and Zn was established in the products considering their content and percentage dialyzability (D%). It was calculated, for a portion of food, the percentage of coverage of the daily requirement of these minerals. Results: the mineral content in the medallions was: [Fe] 1.64-4.21 mg%; [Ca] 104-213 mg% and [Zn] 0.53-3.57 mg%; in beverages it was observed: [Fe] 0.24-2.39 mg%; [Ca] 71-214 mg% and [Zn] 0.18-0.79 mg%. The D% in medallions was: Fe 7,3-11,9; Ca 10.2-18.2 and Zn 17.0-21.4 and for beverages, Fe 5.2-32.8; Ca 6.4-35.7 and Zn 5.9-33.9. The %RD for adolescents, considering a portion of medallions was: Fe women 3.0-9.0%; men 5.0-16%; Ca 0.7-6.8% and Zn 1.5-3.9% and for adults it was: Fe women 3.0-10%; men 7.0-20%; Ca 0.6-5.8% and Zn 2.0-5.1%. When considering beverages, the %RD for adolescents was: Fe women 2.0-28%; men 4.0-53%; Ca 0.4-22% and Zn 1.3-9.5%. For adults it was: Fe women 2.0-31%; men 5.0-64%; Ca 0.3-19% and Zn 1.8-12%. Conclusions: in the medallions, low % RD was observed for the minerals studied. Drinks with added orange or apple juices provided significant amounts of iron. The %RD for zinc and calcium of the sixteen foods was low (both groups studied). Consequently, to meet the requirements of these minerals, it would be necessary to properly combine the foods consumed.

RESUMO

Resumen Introducción: a nivel global, se ha ido incrementando progresivamente la cantidad de personas que adhieren a distintas variantes de dietas vegetarianas. Ello supone, entre otros desafíos, contar con profesionales de la salud y de la nutrición que puedan responder a las necesidades y demandas particulares de estos grupos. Objetivo: indagar conocimientos y actitudes de licenciadas y licenciados en Nutrición de Argentina sobre alimentación ovo-lacto-vegetariana y vegana. Materiales y método: para este estudio observacional, exploratorio y transversal, se diseñó un cuestionario orientado a evaluar conocimientos y actitudes sobre alimentación veg(etari)ana. El muestreo fue no probabilístico, de tipo intencional, convocándose a profesionales de la nutrición residentes en Argentina. Para el análisis de datos se utilizó el programa estadístico SPSS 29.0.0.0. Resultados: la muestra constó de 318 profesionales. Los mayores niveles de información acerca de temas clave de la alimentación y nutrición veg(etari)ana, así como las actitudes orientadas al interés por el impacto de la dieta en el medioambiente y/o en el bienestar animal, se asociaron significativamente con la pertenencia al intervalo de menor edad, menor cantidad de años transcurridos desde el egreso de la carrera de grado y la adherencia propia a dietas ovo-lacto-vegetarianas y veganas. La gran mayoría de los y las profesionales manifestó aceptación y comprensión hacia las elecciones de los/as pacientes veg(etari)anos/as. Conclusiones: los conocimientos y actitudes observados estarían más relacionados con circunstancias generacionales y elecciones personales que con la formación académica. Resulta necesario incluir sistemáticamente en las carreras de grado contenidos de alimentación y nutrición veg(etari)ana con un abordaje integral, contemplando aspectos nutricionales, ambientales y socioculturales.


Abstract Introduction: globally, the number of people who adhere to different variants of vegetarian diets has been progressively increasing. This involves, among other challenges, having health and nutrition professionals who can respond to the particular needs and demands of these groups. Objective: to search knowledge and attitudes of graduates in Nutrition of Argentina on ovo-lacto-vegetarian and vegan diets. Materials and method: for this observational, exploratory and cross-sectional study, a questionnaire was designed to assess knowledge and attitudes about veg(etari)an diets. The sampling was non-probabilistic, intentional, summoning nutrition professionals residing in Argentina. The statistical program SPSS 29.0.0.0 was used for data analysis. Results: the sample consisted of 318 professionals. Higher levels of information about key issues of veg(etari)an food and nutrition, as well as attitudes oriented to interest in the impact of diet on the environment and / or animal welfare, were significantly associated with belonging to the youngest age range, fewer years elapsed since graduation from the undergraduate career and adherence to ovo-lacto-vegetarian and vegan diets. The vast majority of professionals expressed acceptance and understanding towards the choices of vegan patients. Conclusions: the knowledge and attitudes observed would be more related to generational circumstances and personal choices than to academic training. It is necessary to systematically include in the undergraduate courses contents of veg(etari)an food and nutrition with a comprehensive approach, contemplating nutritional, environmental and sociocultural aspects.

RESUMO

Resumen Introducción: la alimentación es uno de los factores modificables más importantes que participa en la salud ósea. Contribuye a ésta, una adecuada ingesta de calcio, vitamina D y proteínas, como así también otros nutrientes. A la alimentación basada en plantas (ABP) se le ha atribuido importantes beneficios para la salud en general, pero mal planificada podría tener efectos deletéreos sobre la salud ósea. Materiales y método: revisión narrativa con búsqueda en el sistema digital de recopilación de información biomédica PubMed cuyo objetivo fue analizar la evidencia científica disponible en la actualidad sobre el efecto de la ABP sobre la salud ósea. Resultados: dentro de los patrones de consumo de la ABP, los veganos que exhiben un consumo de calcio inferior a 525 mg/día presentan mayor riesgo de fractura por fragilidad ósea [incidencia de fractura: 1.37 (IC95%: 1,07; 1,74)]. En cambio, el papel de la hiperhomocisteinemia (HHcy) secundaria al déficit de vitamina B12 y riesgo de fractura continúa siendo controvertido en esta población. Si bien, in vitro la HHcy puede incrementar la actividad de los osteoclastos, en estudios clínicos no se observaron diferencias estadísticamente significativas en los niveles de crosslaps sérico (marcador de resorción ósea) en los consumidores de ABP (vegetarianos) comparados con los omnívoros. Conclusión: una ABP bien planificada, óptima y adecuada, que cubra los requerimientos diarios de calcio, vitamina D, vitamina B12 y proteínas aportará importantes beneficios para la salud general sin afectar la salud ósea en particular, aunque se requiere de futuros estudios para una mejor comprensión de su efecto sobre aspectos específicos del sistema musculo esquelético.


Abstract Introduction: diet is one of the most significant and modifiable factors involved in bone health, as an appropriate intake of calcium, vitamin D and proteins, as well as other nutrients, contributes to this. Significant overall health benefits have been attributed to plant-based diets (PBD); however, poorly planned PBD could have detrimental effects on bone health. Materials and Method: a narrative review through a search in the digital biomedical data collection system PubMed whose objective was to analyze currently available scientific evidence about the effects of PBD on bone health. Results: within the PBD intake patterns, vegans exhibiting calcium intakes below 525mg/day are at a higher risk of fracture due to bone fragility [incidence of fracture: 1.37 (95% CI: 1.07; 1.74)]. In contrast, the role of hyperhomocysteinemia (HHcy) secondary to vitamin B12 deficiency and fracture risk remains controversial in this population. While in vitro HHcy osteoclast activity may increase, in clinical studies no statistically significant differences in serum crosslaps levels (bone resorption marker) were observed in PBD consumers (vegetarians) when compared to omnivores. Conclusion: a well-planned, optimal and adequate PBD, covering daily calcium, vitamin D, vitamin B12 and proteins requirements, will provide significant benefits to the overall health condition without affecting bone health in particular, although future studies are required in order to better understand its effects on specific aspects of the musculoskeletal system.

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

Dietary acid load (DAL) is an important determinant of the acid-base balance in humans and has been associated with several chronic non-communicable diseases. Plant-based diets, including vegetarian and vegan diets, decrease DAL-although their alkalizing potential varies substantially. Their net effect on common DAL scores, including potential renal acid load and net endogenous acid production, has been insufficiently quantified and is poorly understood-particularly in populations outside of Europe and North America. We assessed the associations between three plant-based dietary patterns (flexitarian vs. lacto-ovo-vegetarian vs. vegan diet) and DAL scores in a healthy Venezuelan population in the metropolitan area of Puerto La Cruz, Venezuela. Substantial differences in DAL scores were observed, whereby the vegan diet yielded the highest alkalizing potential, followed by the lacto-ovo-vegetarian and the flexitarian diet. DAL scores were substantially lower in comparison to European and North American plant-based populations, probably due to the higher potassium intake (exceeding 4000 mg/d in vegans), the higher magnesium intake (390.31 ± 1.79 mg/d in vegans) and the lower intake of protein in vegans and lacto-ovo-vegetarians. Additional studies in other non-industrialized populations are warranted to allow for a better understanding of the (numeric) impact of plant-based dietary patterns on DAL scores, potentially allowing for an establishment of reference ranges in the near future.

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

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.

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

ABSTRACT Objective To determine the dietary and sociodemographic profile of vegetarian women of childbearing age (18 and 49 years) from the Valle de Aburrá Metropolitan Area in 2021-2022 Methods Through an online survey, 232 vegetarian and vegan women of childbearing age (18 to 49 years) from the Valle de Aburrá Metropolitan Area were surveyed regarding their sociodemographic characteristics, amount of time following this eating pattern and, type and reason for choosing vegetarianism, physical activity, use of nutritional supplements and frequency of consumption of certain food groups. Descriptive analyses, association of variables with the type of vegetarianism and multinomial regression models were performed. Results A total of 232 vegetarian women were surveyed: 60.8% were between 18 and 30 years of age and belonged mainly to the middle class. According to the type of diet, 68.1% used an ovo-lacto-vegetarian diet, 18.1% were vegan, 9.0% lacto-vegetarian and 4.8% ovo-vegetarian. Among the factors evaluated in their potential relationship with the different types of vegetarianism, it is highlighted that vitamin B12 supplementation presents a statistically significant association when using veganism as a comparison category. Conclusion According to the results, among young female adults the vegetarian eating style predominates, without significant differences as to the educational level, adequate levels of physical activity in most of the population; there was a higher prevalence of ovo-lacto-vegetarianism. Vitamin B12 supplementation was significantly higher in the vegan population, indicating that ovo-lacto and ovo-vegetarian populations may be at high risk of vitamin B12 deficiency.


RESUMO Objetivo O estudo objetivou determinar a associação entre o perfil sociodemográfico e alimentar de mulheres vegetarianas em idade fértil (18 a 49 anos) na região metropolitana de Valle de Aburrá (Colômbia) em 2021-2022. Métodos Por meio de um questionário online, 232 mulheres vegetarianas e veganas em idade fértil (18 a 49 anos) pertencentes à região metropolitana de Valle de Aburrá foram entrevistadas sobre suas características sociodemográficas, tempo, tipo e motivo da escolha do vegetarianismo, atividade física, consumo de suplementos nutricionais e frequência de consumo dos grupos dos alimentos. Foi realizada análise descritiva, associação das variáveis com o tipo de vegetarianismo e modelos de regressão multinomial. Resultados Foram entrevistadas 232 mulheres vegetarianas: 60,8% tinham entre 18 e 30 anos e pertencem principalmente à classe social média. De acordo com o tipo de dieta, 68,1% tinham uma dieta ovolactovegetariana; 18,1%, vegana; 9%, lactovegetariana; e 4,8%, ovovegetariana. Entre os fatores avaliados em sua possível relação com os diferentes tipos de vegetarianismo, destaca-se que a suplementação de vitamina B12 apresenta associação estatisticamente significativa ao ter o veganismo como categoria de comparação. Conclusão De acordo com os resultados, entre mulheres adultas jovens, predomina o estilo alimentar vegetariano, sem diferença significativa observada no nível de escolaridade e níveis adequados de atividade física na maioria da população; há também maior prevalência de ovolactovegetarianismo. A suplementação de vitamina B12 é significativamente maior na população vegana, indicando um alto risco de deficiência nas populações ovolacto e ovovegetarianas.
