Introducción: Evaluar el consumo de alimentos no saludables y prácticas de estilo de vida en mexicanos durante el confinamiento por SARS-CoV-2 (COVID-19).Material y métodos: Estudio transversal realizado durante parte del confinamiento en México. La recolección de datos fue realizada a través de una encuesta digital. Fueron evaluados aspectos de alimentación, bienestar y estilo de vida (consumo de alcohol y tabaco, actividad física y sueño), además de variables sociodemográficas. Para los análisis estadísticos fueron utilizadas la prueba χ2 para comparar diferencias entre género, con significancia estadística del 5%, utilizando el software SPSS 23.0.Resultados: Fueron analizadas 1084 encuestas. La edad promedio fue de 35,5±13,9 años y el 66,5% (n=721) fueron mujeres. En relación a la alimentación antes del confinamiento, 69,8% (n=757) consideraban su alimentación saludable, 6,5% (n=99) muy saludable y 23,7% (n=228) poco saludable, y el 2,3% (n=26) ha mejorado su alimentación, a pesar de esto el 17,1% (n=186) de las personas dice que en estos días come todo el tiempo. En relación al sueño, las mujeres duermen menos durante el periodo del confinamiento (p=0,002) y despiertan más durante la noche cuando se compara con los hombres (p

Chronic kidney disease (CKD) represents a serious concern for the Mexican population since the main predisposing diseases (diabetes, hypertension, etc.) have a high prevalence in the country. The development of frequent comorbidities during CKD such as anemia, metabolic disorders, and hyperphosphatemia increases the costs, symptoms, and death risks of the patients. Hyperphosphatemia is likely the only CKD comorbidity in which pharmaceutical options are restricted to phosphate binders and where nutritional management seems to play an important role for the improvement of biochemical and clinical parameters. Nutritional interventions aiming to control serum phosphate levels need to be based on food tables, which should be specifically elaborated for the cultural context of each population. Until now, there are no available food charts compiling a high amount of Mexican foods and describing phosphorus content as well as the phosphate to protein ratio for nutritional management of hyperphosphatemia in CKD. In this work, we elaborate a highly complete food chart as a reference for Mexican clinicians and include charts of additives and drug phosphate contents to consider extra sources of inorganic phosphate intake. We aim to provide an easy guideline to contribute to the implementation of more nutritional interventions focusing on this population in the country.

Over the past decades, Mexico has become one of the main sweetener-consuming countries in the world. Large amounts of these sweeteners are in dairy products aimed at the children’s market in various presentations such as yogurt, flavored milk, flan, and cheeses. Although numerous studies have shown the impact of sweeteners in adults, the current evidence for children is insufficient and discordant to determine if these substances have any risk or benefit on their well-being. Therefore, this study aimed to describe the sweeteners present in 15 dairy products belonging to the school-age children’s market in Mexico and their impact on health. These dairy products were selected through a couple of surveys directed at parents of school-age children. After that, the list of ingredients of each product was analyzed to identify their sweetener content. From there, exhaustive bibliographic research on sweeteners and their possible health effects was carried out, which included 109 articles and 18 studies. The results showed that at a neurological, endocrinological, cardiovascular, metabolic, osseous, renal, hepatic, dental, reticular, carcinogenic, and gut microbiota level; sucrose, fructose, high-fructose corn syrup, maltodextrins, sucralose, and acesulfame K, have a negative effect. While maltodextrins, stevia, polydextrose, and modified starch have a positive one. For these reasons, it is necessary to evaluate the advantages and disadvantages that the consumption of each sweetener entails, as well as a determination of the appropriate acceptable daily intake (ADI).

Para los nahuas de la Sierra Negra de Puebla, el consumo de maiz es considerado uno de los elementos que establecen la distincion entre los humanos y los no humanos, pues mediante este se crean cuerpos que se diferenciaran, entre otras cosas, por su estabilidad o la falta de ella. La fabricacion del cuerpo requiere de una serie de acciones realizadas a lo largo de toda la vida. En este texto se dara cuenta, principalmente, de la importancia que tiene la alimentacion mediante productos locales (por ejemplo, maiz y frijol) –frente a aquella que conforma cuerpos anomalos como el de los migrantes–, asi como el consumo de sal y el bautizo, para dar paso a la descripcion del papel que juega el trabajo en la milpa en la conformacion de cuerpos adecuados para lo nahua , es decir, lo humano por excelencia. Se pondra especial enfasis a la ninez como una etapa donde el control de la inestabilidad requiere de un esfuerzo mayor. Los ninos nahuas son asociados a los antepasados, a lo acuoso y a lo mitico. Su humanidad esta constantemente en riesgo, pues su cuerpo no ha llegado a los niveles necesarios de madurez. Abstract: For the Nahuas of the Sierra Negra de Puebla, the consumption of corn is considered one of the elements that establish the distinction between humans and non-humans, because through it bodies are created that will be differentiated, among other things, by their stability or the lack of it. The manufacture of the body requires a series of actions carried out throughout life. In this text, it will be realize, mainly, the importance of food through local products (corn and beans, for example) compared to that which forms anomalous bodies such as migrants, as well as the consumption of salt and baptism, for give way to the description of the role that work in the cornfield plays in shaping bodies suitable for “the Nahua”, that is, the human par excellence. Special emphasis will be given to children as a stage where the control of instability requires a greater effort. Nahua children are associated with the ancestors, the aqueous and the mythical. His humanity is constantly at risk, because his body has not reached the necessary levels of maturity. Keywords : childhood; transformation; food; Nahuas; Sierra Negra. Resume : Pour les Nahuas de la Sierra Negra de Puebla, la consommation de mais est consideree comme l’un des elements permettant d’etablir la distinction entre humains et non-humains, car grâce a elle, des corps sont crees qui se differencieront, entre autres, par leur stabilite ou le manque de ca. La fabrication du corps necessite une serie d’actions menees tout au long de la vie. Dans ce texte, il se rendra compte principalement l’importance de l’alimentation par le biais de produits locaux (par exemple, mais et haricots) par rapport a celle qui forme des corps anormaux tels que les migrants, ainsi que la consommation de sel et le bapteme, par exemple. Cedez le pas a la description du role que joue le travail dans le champ de mais dans la formation d’organes propres au « Nahua », c’est-a-dire a l’humain par excellence. L’attention sera mise sur les enfants en tant qu’etape ou la maitrise de l’instabilite exige des efforts accrus. Les enfants nahuas sont associes aux ancetres, aux aqueux et aux mythiques. Son humanite est constamment en danger, car son corps n’a pas atteint les niveaux de maturite necessaires. Mots-cles : enfance ; transformation ; nutrition ; Nahuas ; Sierra Negra.
