Popular Diets and Skin Effects: A Narrative Review. / Dietas populares y su impacto en la piel. Una revisión narrativa.

Numerous diets for losing weight, building strength, and managing a range of cardiovascular, neurologic, and skin diseases have become popular in recent years. The ketogenic diet and intermittent fasting in particular have shown promising results in clinical and sports medicine. The Mediterranean diet, in turn, is widely recognized for its numerous health benefits. Also popular are the paleo diet and vegan and gluten-free diets. Positive effects on inflammatory conditions, such as psoriasis, atopic dermatitis, hidradenitis suppurativa, and acne, have been observed in patients who practice intermittent fasting or follow ketogenic or Mediterranean diets. This last choice may also protect against certain skin cancers. We review the role of several popular diets in the management of skin disorders.

[Association between diet of the vegan population and self-perception of periodontal state in Metropolitan Lima]. / Asociación entre la dieta de la población vegana y la autopercepción del estado periodontal en Lima Metropolitana.

INTRODUCTION: Objective: to determine the association between vegan diet and self-perceived periodontal status in a vegan population of Metropolitan Lima, Peru. Materials and methods: a total of 240 people (120 vegans and 120 non-vegans) were surveyed in this study during the months of August to December 2020 in a virtual way. To evaluate self-perception of periodontal status and oral hygiene habits, the self-report of periodontal disease was used, which is validated with a Cronbach's alpha of 0.77. In addition, other variables such as age, sex, socioeconomic level, educational level, and tobacco consumption were registered. A Poisson regression with robust variance estimator was used both for the association of variables, and prevalence ratios were reported in a crude and adjusted model. The confidence level was 95 % and the significance level was p < 0.05. Results and conclusions: a statistically significant association was found between the appearance of reddish and/or swollen gums (PR = 0.67; 95 % CI: 0.25-0.54) and poor perception of the state of the gums (PR = 0.43; 95 % CI: 0.33-0.56) with the vegan diet. Finally, for the gum bleeding dimension during brushing, no statistically significant differences were observed between vegans and non-vegans.

INTRODUCCIÓN: Objetivo: determinar la asociación entre la dieta vegana y la autopercepción del estado periodontal en una población vegana de Lima Metropolitana, Perú. Materiales y métodos: un total de 240 personas (120 veganas y 120 no veganas) fueron encuestadas en este estudio durante los meses de agosto a diciembre del año 2020 de manera virtual. Para evaluar la autopercepción del estado periodontal y los hábitos de higiene oral se utilizó el autorreporte de enfermedad periodontal, que se encuentra validado con una alfa de Cronbach de 0,77. Además se registraron otras variables como la edad, el sexo, el nivel socioeconómico, el grado de estudio y el consumo de tabaco. Se utilizó la regresión de Poisson con estimador robusto de la varianza para la asociación de las variables y se reportaron razones de prevalencia en un modelo crudo y ajustado. El nivel de confianza fue del 95 % y el de significancia fue de p < 0,05. Resultados y conclusiones: se encontró asociación estadísticamente significativa entre la apariencia de encías rojizas y/o hinchadas (RP = 0,67; IC 95 %: 0,25-0,54) y la mala percepción del estado de las encías (RP = 0,43; IC 95 %: 0,33-0,56) con la dieta vegana. Por último, para la dimensión del sangrado de encías durante el cepillado no se observaron diferencias estadísticamente significativas entre las personas veganas y las no veganas.

Nutritional imbalances in a Mexican vegan group: urgent need for country-specific dietary guidelines.

Introduction: Introduction: vegan diets exclude the consumption of animal-derived products, and health advantages have been reported when followed. However, heterogeneous eating habits, food availability, and sociocultural characteristics among regions could lead to different physiological results. Case reports: twelve patients following a strict vegan diet for an uninterrupted period of ≥ 3 years were subjected to clinical assessment. Patients significantly exceeded the suggested intake for sugar, presented six mineral deficiencies, and exhibited three vitamins below the recommended consumption. We further identified hyperglycemia, hypertriglyceridemia, subnormal serum vitamin B12 concentrations, as well as macrocytosis and microcytic anemia in several participants. Discussion: this Mexican vegan diet is strongly influenced by endemic and cultural adaptations that could limit the benefits reported in other populations. Professional guidance is required to avoid specific deficiencies with potential repercussions. We urge country-specific vegan guidelines considering local eating habits, food availability, and sociocultural perspectives around food.

Introducción: Introducción: la dieta vegana excluye el consumo de productos de origen animal y se ha vinculado con una disminución del riesgo de morbimortalidad. Sin embargo, los distintos hábitos alimentarios entre países podrían condicionar los beneficios reportados para las dietas basadas en vegetales. Casos clínicos: doce pacientes siguiendo una estricta dieta vegana por ≥ 3 años se sometieron a una evaluación clínica. Exhibieron una ingestión de azúcar que supera el consumo sugerido, presentaron tres deficiencias vitamínicas y seis de minerales. Se identificó la presencia de hiperglucemia, hipertrigliceridemia, concentraciones séricas subnormales de vitamina B12, macrocitosis y anemia microcítica en varios participantes. Discusión: la dieta vegana de este grupo resultó fuertemente influenciada por adaptaciones culturales que podrían limitar los beneficios reportados en otras poblaciones. Se requiere orientación profesional para evitar desequilibrios nutricionales. Enfatizamos la necesidad del desarrollo de guías alimentarias y de práctica clínica que consideren los hábitos alimentarios locales, la disponibilidad de alimentos en la región y las perspectivas socioculturales en torno a la dieta vegana.

[Pellagra: an ancient disease in a modern world]. / Pelagra: una enfermedad antigua en un mundo moderno.

INTRODUCTION: Introduction: pellagra is a systemic disease due to deficiency of vitamin B3 or tryptophan, its precursor. Vitamin B3 is needed for several metabolic processes, cell signaling, and DNA repair. It is characterized by a classic tetrad of dermatitis, diarrhea, dementia, and death. Pellagra is considered rare nowadays; however, due to the popularity of restrictive diets without necessary supplementation such us veganism, there has been an increase in cases in recent years. Clinical case: we report the case of a young strict vegan female patient in which a pellagra diagnosis was made, and early treatment was administered with an excellent outcome. Discussion: the interest of this case lies in the importance of clinical suspicion and directed history taking focused on social and nutritional factors, as adapted for the current times, in order to make the diagnosis of a rare, subdiagnosed disease that is life-threatening if treatment is delayed.

INTRODUCCIÓN: Introducción: la pelagra es una enfermedad sistémica secundaria a la deficiencia de vitamina B3 o de su precursor, el triptófano. La vitamina B3 es necesaria para varios procesos metabólicos, de señalización celular y reparación del ADN. Se caracteriza por la tétrada clásica de dermatitis, diarrea, demencia y muerte. La misma es considerada una enfermedad rara hoy en día; sin embargo, con el auge de las dietas restrictivas sin la adecuada suplementación, como es el caso del veganismo, se ha visto un aumento de los casos en los últimos años. Caso clínico: exponemos el caso de una paciente adulta joven, vegana estricta, a la cual se le realizó el diagnóstico de pelagra y se le instauró un tratamiento de forma precoz, con una excelente evolución. Discusión: el interés del caso radica en la importancia de la sospecha clínica y la anamnesis dirigida a factores sociales y nutricionales, adaptados a la época actual, para poder hacer el diagnóstico de una enfermedad rara e infradiagnosticada que es potencialmente mortal de retrasarse el inicio del tratamiento.

[Severe encephalopathy and vitamin B12 deficiency: reversibility after nutritional therapy]. / Encefalopatía grave y deficiencia de vitamina B12: reversibilidad tras la terapia nutricional.

INTRODUCTION: Introduction: the vitamin cobalamin is essential for a proper functioning of the CNS, hematopoiesis, and DNA synthesis. Its deficiency is frequently secondary to pernicious anemia or strict vegetarian diets. Case report: an 18-month-old male infant presented with a decreased level of consciousness and movement disorder (tremor and choreiform movements) of several hours' standing. He had a history of delayed acquisition of motor milestones (not standing, monosyllabic language), and progressive loss of these over the last few weeks (head support and sitting). He had been breastfed from birth. His family has a vegetarian diet. In neuroimages, cranial CT and MRI scans showed generalized supratentorial atrophy involving both matters and the basal ganglia. Treatment was started with intramuscular vitamin B12, which increased its levels. Subsequently, the patient was subjected to dietary diversification and oral cyanocobalamin, with clinical normalization after 6 months and radiological normalization after 7 months. Conclusions: we emphasize the importance of vitamin B12 supplementation during pregnancy and lactation in vegetarina mothers and their infants.

INTRODUCCIÓN: Introducción: la vitamina cobalamina es esencial para el buen funcionamiento del SNC, la hematopoyesis y la síntesis de ADN. Su déficit es frecuentemente secundario a la anemia perniciosa o a las dietas vegetarianas estrictas. Caso clínico: lactante varón de 18 meses con disminución del nivel de conciencia y trastorno del movimiento (temblor y movimientos coreiformes) de horas de duración. Como antecedentes, presenta retraso de adquisición de hitos motores (no bipedestación, lenguaje monosilábico) y pérdida progresiva de los mismos en lúltimas semanas (sostén cefálico y sedestación). Alimentado mediante lactancia materna desde el nacimiento. La familia sigue una alimentación vegetariana. En las pruebas de neuroimagen, la TC y la RM craneales muestran atrofia supratentorial generalizada de ambas sustancias y de los ganglios basales. Se inicia tratamiento con vitamina B12 intramuscular, aumentando sus niveles. Posteriormente se procede a la diversificación alimentaria y la administración de cianocobalamina oral, con normalización clínica al cabo de 6 meses y radiológica al cabo de 7 meses. Conclusiones: recalcamos la importancia de la suplementación con B12 durante el embarazo y lactancia tanto en la mujer como en el lactante.

Spanish population trends in Internet searches for information on different diets. / Tendencia de la población española de búsqueda en internet sobre información relacionada con diferentes dietas.

OBJECTIVE: To use Google Trends to explore the trends of interest of the Spanish population regarding information related to different types of diets, focused on those that are popular and with evidence-based studies, over the last 10years. MATERIAL AND METHODS: The search trends referred to the terms «Mediterranean diet¼, «ketogenic diet¼, «low fat diet¼, «intermittent fasting¼ and «vegan diet¼ were analyzed. The relative search volumes (RSV) of the terms were compared. The direction of the trend was studied using the Spearman's correlation coefficient (SC). RESULTS: «Mediterranean diet¼ was the most widely searched term, with a median RSV of 16 (interquartile range [IQR] 6; range 8-100), though it exhibited a decreasing chronological trend (SC=-0.216). It was followed by «ketogenic diet¼, with an RSV of 8 (IQR 9; range 1-57); «vegan diet¼, with an RSV of 4 (IQR 5; range 0-16); «intermittent fasting¼, with an RSV of 2 (IQR 5; range 0-27), and «low fat diet¼, with an RSV of 1.16 (IQR 0; range 0-2). The term with the best correlation over time was «intermittent fasting¼ (SC=0.96), followed by «ketogenic diet¼ (SC=0.91) and «vegan diet¼ (SC=0.85). CONCLUSIONS: In Spain, the interest of the population in information about the Mediterranean diet is greater than for other diets. However, in recent years there has been a progressive increase in interest (measured as RSV) in other diets such as the ketogenic diet, vegan diet or intermittent fasting, and there has been a decrease in interest in the Mediterranean diet. The low fat diet does not generate interest in the Spanish population.

[Are vegetarian diets nutritionally adequate? A revision of the scientific evidence]. / ¿Son las dietas vegetarianas nutricionalmente adecuadas? Una revisión de la evidencia científica.

INTRODUCTION: Vegetarian diets are booming and, although these diets have been linked to some health benefits, the low bioavailability of some micronutrients in plant foods may result in risk of nutritional deficiencies, which makes necessary adequate planning of these diets. In this regard, vitamin B12 deficiency in vegetarians has been evidenced and there is a consensus on the need of supplementation of this vitamin. Vitamin D deficiency may be more frequent than in omnivores, particularly during the winter, when skin synthesis is minimal. The low bioavailability of iron, zinc and selenium in vegetables can also affect nutritional status of vegetarians. Furthermore, vegetarian diets are usually deficient in polyunsaturated fatty acids of the omega-3 family, eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids. On the other hand, these diets appear to provide adequate quantities of other vitamins, such as ascorbic acid, folic acid and the fat-soluble vitamins A and E. In this review, the characteristics of the intake of macro- and micronutrients of vegetarian diets and the diet and health relationships are presented. In addition, data on nutritional status of this population are also shown and suggestions on nutritional recommendations to prevent deficiencies are given. Finally, the possible clinical application of controlled interventions with vegetarian diets is presented.

INTRODUCCIÓN: El seguimiento de dietas vegetarianas está en auge y, aunque estas se han relacionado con algunos beneficios para la salud, la baja biodisponibilidad de determinados micronutrientes en los alimentos vegetales puede resultar en riesgo de déficit nutricional, por lo que se hace necesaria una adecuada planificación de dichas dietas. En este sentido, se ha evidenciado el déficit de vitamina B12 en vegetarianos y está consensuada la necesidad de ingerir complementos de esta vitamina. La deficiencia de vitamina D puede ser más frecuente que en omnívoros, particularmente durante el invierno, cuando la síntesis cutánea es mínima. La baja biodisponibilidad del hierro, el zinc y el selenio en los alimentos vegetales puede afectar también al estado nutricional de vegetarianos. Además, las dietas vegetarianas suelen ser deficitarias en ácidos grasos poliinsaturados de la serie omega-3, eicosapentaenoico (EPA) y docosahexaenoico (DHA). Por otro lado, estas dietas sí parecen aportar cantidades adecuadas de otras vitaminas, como el ácido ascórbico, el ácido fólico y las vitaminas liposolubles A y E. En esta revisión se presentan las características de la ingesta de macro- y micronutrientes procedentes de las dietas vegetarianas y la relación dieta-salud. Se exponen, además, datos sobre el estado nutricional de adultos que consumen dichas dietas, proponiendo recomendaciones nutricionales primordiales para prevenir deficiencias. Finalmente, se presenta la posible aplicación clínica de intervenciones controladas con dietas vegetarianas.

[An exploratory study of vegetarianism in catering establishment]. / Estudio exploratorio del vegetarianismo en restauración colectiva.

INTRODUCTION: Introduction: interest in vegetarian diets is rising, however, it remains a very controversial topic, and with many reservations regarding it. Questions like their conceivable nutritional deficiencies, or if they are adequate or healthy, might be widely unknown. Objectives: exploring vegetarian diets, examining the current level of knowledge about them, and analyzing and improving, from a nutritional standpoint, the vegetarian menus of a restaurant with vegetarian options. Methods: this study was designed as an exploratory, crossover, descriptive study. Surveys with 17 items and a food frequency questionnaire were given among the customers of the restaurant. A total of 155 people, aged between 18 and 62, took part in it. A total of 30 menus were analyzed, and some suggestions were made in order to improve them. Results: out of the total sample, 138 people were omnivores, 12 people were vegetarians and two were vegans. More than half of the vegetarians did not know vitamin B12 is the only required supplement by default, and almost 60% of them stated never taking B12 supplements. The vegetarian menus which were analyzed provided a mean of 1,195 kcal, and covered 89% of the requirements of fiber, 212% of vitamin C, ≈30% of both calcium and zinc, 86% of iron, and 38% of B12. Conclusion: a great lack of knowledge regarding several aspects of vegetarian diets was found, even among vegetarian themselves. Informing the general public is essential for both avoiding dangerous nutritional deficiencies (like B12), and attracting more people towards this kind of diets, with all the benefits this would provide. In the vegetarian menus of Foodtopía, adequate levels of nutrients were observed. The main suggestions to improve the menus were: reducing the total calories and the amount of sunflower oil, and increasing the amount of legumes, nuts and seeds.

INTRODUCCIÓN: Introducción: el interés por las dietas vegetarianas está en auge, pero siguen existiendo muchas dudas y controversia al respecto. Temas como sus posibles deficiencias nutricionales, o si son adecuadas o saludables, podrían no ser ampliamente conocidos. Objetivos: explorar estas dietas, ver el nivel de conocimiento que existe sobre ellas y analizar y mejorar nutricionalmente los menús vegetarianos de un restaurante con opciones vegetarianas. Métodos: el diseño del estudio fue de tipo descriptivo, transversal y exploratorio. Se entregaron cuestionarios con 17 preguntas y un cuestionario de frecuencia de consumo de alimentos entre los clientes del restaurante. Participaron un total de 155 personas, con un rango de edad de 18-62 años. Se analizaron un total de 30 menús y se hicieron sugerencias para mejorarlos. Resultados: de la muestra total, 138 personas eran omnívoras, 12 eran vegetarianas y dos, veganas. Más de la mitad de los vegetarianos no sabían que la única suplementación necesaria por defecto es la B12 y el ≈60% de ellos dijo no suplementarse nunca con ella. Los menús vegetarianos analizados aportaban de media 1.195 kcal y cubrían el 89% de la ingesta recomendada de fibra, el 212% de vitamina C, ≈30% de calcio y zinc, el 86% de hierro y el 38% de B12. Se observaron niveles insuficientes de vitamina D. Conclusiones: existe un gran desconocimiento sobre muchos aspectos de las dietas vegetarianas, incluso entre los propios vegetarianos. Informar al público es primordial, tanto para evitar deficiencias nutricionales potencialmente peligrosas (B12), como para atraer a más personas hacia este tipo de dietas, con los beneficios que esto acarrearía. Se observaron niveles muy adecuados de nutrientes en los menús vegetarianos de Foodtopía. Las principales sugerencias de mejora fueron: reducir las calorías totales y la cantidad de aceite de girasol y aumentar la cantidad de legumbres, frutos secos y semillas.

Characterization of the dietary and sociodemographic profile of a group of Colombian vegetarian women in childbearing age during the period 2021-2022 / Caracterização do perfil alimentar e sociodemográfico de um grupo de mulheres vegetarianas colombianas em idade fértil no período 2021-2022

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.

Aquafaba proveniente da cocção do grão-de-bico (CicerarietinumL): características químicas, padronização do uso e aplicação culinária / Aquafaba obtained from chickpea cooking: Chemical characterization, standardization of use and viability in a recipe

Introdução: A aquafaba, proveniente da cocção do grão-de-bico (CicerarietinumL.), pode ser uma alternativa interessante para formação de espuma, sendo um ingrediente vegetal capaz de conferir características físico-químicas e sensoriais agradáveis a preparações culinárias veganas. Objetivo: Padronizar o processo de obtenção da aquafaba caseira visando aplicação em preparação culinária vegana. Material e Métodos: Após remolho dos grãos, foram utilizadas diferentes proporções de grão e água (v:v) durante o cozimento, totalizando seis experimentos. As amostras de aquafaba caseira foram analisadas quanto à capacidade de formação e estabilidade de espuma e os resultados foram comparados à clara de ovo, visando escolher a melhor proporção grão:água para desenvolvimento de uma mousse de chocolate vegana. As amostras de mousse padrão (clara de ovo) e vegana (aquafaba) foram submetidas ao teste de aceitação utilizando escala hedônica de nove pontos (n = 95 provadores não treinados). Resultados: A espuma da clara de ovo apresentou menor estabilidade (p<0,05), sendo que a aquafaba obtida a partir da proporção 2:3 formou espuma em menor tempo comparado aos demais experimentos. Essa mesma amostra não apresentou diferença significativa na formação e estabilidade de espuma em relação às demais, sendo então utilizada para elaborar a mousse vegana, a qual não diferiu quanto ao sabor (p>0,05) e apresentou melhores médias dos demais atributos avaliados, comparada à mousse padrão (p<0,05). Conclusão: A aquafaba caseira de grão-de-bico (Cicerarietinum L.), 2:3 (grão:água v/v) mostrou boa viabilidade para aplicação culinária em mousse vegana.

Introduction: Aquafaba is a by-product of chickpeas (Cicer arietinum L.) that may represent an interesting alternative forproviding foam formation,at the same time as beinga vegetal ingredient that has pleasant physicochemical and sensory characteristics in culinary vegan recipes. Objective:Standardize the homemade process to obtain aquafaba, with the aim of using it invegan recipes. Material and Methods: After soaking chickpeas overnight, different proportions of chickpea and water (v/v) were used during the cooking process, in six experiments. The homemade aquafaba samples were analyzed with regard to foam formation and stability, and the results were compared to those of egg white, in order to determine the best proportion of grain:waterfor developing a vegan chocolate mousse. The samples of standard (egg white) and vegan (aquafaba) mousse went through an acceptability test using a 9-point structured hedonic scale (n= 95 untrained tasters). Results: The foam obtained from egg white presentedlower stability (p<0.05), while the aquafaba obtained from a 2:3 grain:water proportion formed foam more quickly, when compared to that obtained from other experiments. This same sample did not present any significant difference in foam formation and stability, compared to the other samples and was selected for the vegan mousse preparation, which did not differ in terms of flavor (p>0.05) and presented better means in the other features evaluated, when compared to standard mousse (p<0.05). Conclusion: The homemade chickpea (Cicer arietinum L.) aquafaba obtained from a 2:3 proportion of grain:water(v/v) presented viability for culinary application in vegan mousse.

Crecimiento en niños y en hijos de madres que adhieren a dietas vegetarianas: revisión de la literatura / Growth in children and in the offspring whose mothers adhere to vegetarian diets: Literature review

Introducción. La prevalencia del vegetarianismo aumenta a nivel mundial y no hay consenso acerca de si este tipo de alimentación es adecuado durante el período de crecimiento. Objetivo. Se realizó una revisión descriptiva de la literatura con el objetivo de conocer si los niños e hijos de madres que siguen dietas vegetarianas crecen de manera diferente a los niños con dietas omnívoras. Métodos. Se incluyen 25 artículos publicados entre los años 1995-2020, que describen el crecimiento prenatal, postnatal y desarrollo puberal en niños vegetarianos e hijos de madres vegetarianas. Conclusión. La escasez de estudios longitudinales y resultados en el largo plazo, la heterogeneidad en la clasificación y el registro de las dietas, además de deficiencias metodológicas, no permiten concluir que el crecimiento de estos niños sea diferente al de los niños que siguen dietas omnívoras. Se requieren estudios longitudinales en el largo plazo para contribuir a dirimir esta controversia

The prevalence of vegetarianism is rising worldwide and there is no consensus about whether it is adequate during the growth period. The objective of this descriptive review is to find out if vegetarian children and children born from mothers who follow vegetarian diets, grow different from those who follow omnivorous diets. Results. 25 articles published between 1995 and 2020 were included describing prenatal and postnatal growth and pubertal development in vegetarian children and children of vegetarian mothers. Conclusion. The scarcity of longitudinal studies and long-term results, the heterogeneity in the classification and registration of the diets, in addition to methodological deficiencies, do not allow to conclude that the growth of these children is different from children on omnivorous diets. Long-term longitudinal studies are required to help to solve this controversy

Níveis de concordância com regras descritivas sobre comportamentos alimentares entre veg(etari)anos / Levels of agreement with descriptive rules on food behavior between vegans and vegetarians / Niveles de acuerdo con reglas descriptivas sobre comportamientos alimentarios entre veg(etari)anos

O vegetarianismo é uma prática que exclui carnes e pode evitar outros produtos de origem animal. Esta última modalidade está muito associada ao veganismo, uma filosofia que defende a libertação animal. Aderir a tais condições implica no seguimento de algumas normas que norteiam comportamentos alimentares e interações sociais. Partindo desse pressuposto, objetivou-se avaliar o nível de concordância, entre vegetarianos e veganos, quanto a regras que descrevem comportamentos alimentares. A pesquisa contou com 398 participantes, sendo 198 não estritos e 200 estritos, que responderam a um questionário on-line autoaplicável. Os dados, analisados via teste t, apontaram maiores níveis de concordância com comportamentos mais restritos entre vegetarianos estritos e veganos os quais também relataram maior embasamento em valores. Este estudo, que trouxe uma ótica de análise para os comportamentos alimentares em termos de localização de reforços, pode contribuir com novas práticas em saúde direcionadas às pessoas vegetarianas e veganas. (AU)

Vegetarianism is a practice that excludes meat and can avoid other products of animal origin. This latter modality is closely associated with veganism, a philosophy that advocates animal liberation. Adherence to these conditions implies following some norms that guide eating behaviors and social interactions. Based on this assumption, we aimed to evaluate the agreement level, between vegetarians and vegans, regarding rules that describe food behaviors. The survey included 398 participants, 198 non-strict and 200 strict vegetarians, who answered a self-administered online questionnaire. The data, analyzed by t-test, showed higher agreement level with more restricted behaviors between strict vegetarians and vegans, who also reported a higher base on values. This study, which provided an analysis perspective on eating behaviors in terms of reinforcement location, may contribute to new health practices aimed at vegetarians and vegans. (AU)

Estado nutricional, hábitos de alimentación y de estilo de vida en vegetarianos de Asunción y Gran Asunción, Paraguay / Nutritional status, eating habits and lifestyle factors among vegetarians from Asunción and Great Asunción, Paraguay

RESUMEN Una dieta vegetariana se define por la exclusión total o parcial de alimentos de origen animal. Cuando es planificada adecuadamente puede prevenir y tratar enfermedades. Sin embargo, una dieta restrictiva en ciertos alimentos debe ser evaluada. El propósito de esta investigación fue describir parámetros antropométricos, hábitos de alimentación y de estilo de vida en ovo-lácteo-vegetarianos y veganos y explorar diferencias en la ingesta de nutrientes críticos entre ambos grupos. Estudio descriptivo de corte transversal, realizado en ovo-lácteo-vegetarianos y veganos de Asunción, Paraguay, durante el 2015. Se evaluaron parámetros antropométricos,, ingesta y hábitos de estilo de vida saludable. Participaron 17 ovo-lácteo-vegetarianos y 14 veganos. El 67,7 % (n= 21) se encontró normopeso, el 29 % (n= 9) presentó exceso de peso, y el 3,2% (n=1) bajo peso. Se presentó una ingesta inferior a los requerimientos en energía, carbohidratos, proteínas y grasas en ambos grupos de vegetarianos, e ingesta muy limitada de calcio y vitamina B12 en veganos. Las mujeres presentaron ingesta muy por debajo de las recomendaciones para hierro y calcio. Ninguna mujer vegana cumplió con la recomendación dietaria de vitamina B12. Al comparar grupos, se hallaron diferencias significativas en proteínas, calcio (menor consumo en veganos) y fibra (menor en ovo-lácteo-vegetarianos). La suplementación con vitaminas y suplementos también fue muy baja. Los resultados resaltan la importancia de una evaluación constante de la ingesta de nutrientes en una dieta vegetariana, a modo de evitar deficiencias o excesos, y la insoslayable tarea del nutricionista para el asesoramiento alimentario-nutricional a los individuos que expresen interés en adoptar este tipo de dieta.

ABSTRACT A vegetarian diet is defined by the total or partial exclusion of foods of animal origin. When properly planned it can prevent and treat disease. However, a restrictive diet in certain foods must be evaluated. The purpose of this research was to describe anthropometric parameters, eating and lifestyle habits of lacto-ovo-vegetarians and vegans, and to explore differences in critical nutrient intake between both groups. We conducted a descriptive cross-sectional study, carried out among lacto-ovo-vegetarians and vegans in the city of Asunción, Paraguay, during 2015. Anthropometric parameters,, intake and healthy lifestyle habits were evaluated. Seventeen lacto-ovo-vegetarians and 14 vegans participated. 67.7% (n= 21) were normal weight, 29.1% (n= 9) were overweight, and 3.2% (n= 1) were underweight. There was an intake lower than the requirements in terms of energy, carbohydrates, proteins and fats in both groups of vegetarians, and very limited intake of calcium and vitamin B12 in vegans. Women particularly had intake well below the recommendations for iron and calcium. No woman on a vegan diet met the dietary recommendation for vitamin B12. When comparing groups, significant differences were found in terms of protein and calcium, (lower consumption in vegans), fiber (lower in lacto-ovo-vegetarians). Vitamin supplementation was also very low. The results highlight the importance of constant evaluation of nutrient intake in a vegetarian diet in order to avoid deficiencies or excesses, and the very important work of the nutritionist for food and nutritional advice for individuals who express interest in adopting this type of diet.
