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)

Plant-based diets have emerged as athletic performance enhancers for various types of exercise. Therefore, the present study evaluated the effectiveness of plant-based diets on aerobic and strength/power performances, as well as on BMI of physically active individuals. This systematic review and meta-analysis was conducted and reported according to the guidelines outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. A systematic search of electronic databases, including PubMed, Web of Science and SPORTDiscus, was performed. On the basis of the search and inclusion criteria, four and six studies evaluating the effects of plant-based diets on aerobic and strength/power performances in humans were, respectively, included in the systematic review and meta-analysis. Plant-based diets had a moderate but positive effect on aerobic performance (0·55; 95 % CI 0·29, 0·81) and no effect on strength/power performance (-0·30; 95 % CI -0·67, 0·07). The altogether analyses of both aerobic and strength/power exercises revealed that athletic performance was unchanged (0·01; 95 % CI -0·21, 0·22) in athletes who adopted plant-based diets. However, a small negative effect on BMI (-0·27; 95 % CI -0·40, -0·15) was induced by these diets. The results indicate that plant-based diets have the potential to exclusively assist aerobic performance. On the other hand, these diets do not jeopardise strength/power performance. Overall, the predicted effects of plant-based diets on physical performance are impactless, even though the BMI of their adherents is reduced.
