Effects of Foods of Mesoamerican Origin in Adipose Tissue and Liver-Related Metabolism.

Adipose tissue and liver metabolism play a key role in maintaining body homeostasis; therefore, their impairment conduces a pathological state. Nowadays, occidental lifestyle is a common etiological issue among a variety of chronic diseases, while diet is a unique strategy to prevent obesity and liver metabolism impairment and is a powerful player in the treatment of metabolic-related diseases. Mesoamerican foods are rich in bioactive molecules that enhance and improve adipose tissue and liver performance and represent a prophylactic and therapeutic alternative for disorders related to the loss of homeostasis in the metabolism of these two important tissues.

Breastfeeding-Related Health Benefits in Children and Mothers: Vital Organs Perspective.

Breast milk (BM) is a constantly changing fluid that represents the primary source of nutrition for newborns. It is widely recognized that breastfeeding provides benefits for both the child and the mother, including a lower risk of ovarian and breast cancer, type 2 diabetes mellitus, decreased blood pressure, and more. In infants, breastfeeding has been correlated with a lower risk of infectious diseases, obesity, lower blood pressure, and decreased incidence of respiratory infections, diabetes, and asthma. Various factors, such as the baby's sex, the health status of the mother and child, the mother's diet, and the mode of delivery, can affect the composition of breast milk. This review focuses on the biological impact of the nutrients in BM on the development and functionality of vital organs to promote the benefit of health.

ß-Caryophyllene: A Therapeutic Alternative for Intestinal Barrier Dysfunction Caused by Obesity.

Obesity is an excessive accumulation of fat that exacerbates the metabolic and inflammatory processes. Studies associate these processes with conditions and dysregulation in the intestinal tract, increased concentrations of lipopolysaccharides (LPSs) in the blood, differences in the abundance of intestinal microbiota, and the production of secondary metabolites such as short-chain fatty acids. ß-Caryophyllene (BCP) is a natural sesquiterpene with anti-inflammatory properties and with the potential purpose of fighting metabolic diseases. A diet-induced obesity model was performed in 16-week-old C57BL/6 mice administered with BCP [50 mg/kg]. A reduction in the expression of Claudin-1 was observed in the group with a high-fat diet (HFD), which was caused by the administration of BCP; besides BCP, the phylaAkkermansia and Bacteroidetes decreased between the groups with a standard diet (STD) vs. HFD. Nevertheless, the use of BCP in the STD increased the expression of these phyla with respect to fatty acids; a similar effect was observed, in the HFD group that had a decreasing concentration that was restored with the use of BCP. The levels of endotoxemia and serum leptin increased in the HFD group, while in the HFD + BCP group, similar values were found to those of the STD group, attributing the ability to reduce these in conditions of obesity.

Escherichia/Shigella, SCFAs, and Metabolic Pathways-The Triad That Orchestrates Intestinal Dysbiosis in Patients with Decompensated Alcoholic Cirrhosis from Western Mexico.

Gut microbiota undergoes profound alterations in alcohol cirrhosis. Microbiota-derived products, e.g., short chain fatty acids (SCFA), regulate the homeostasis of the gut-liver axis. The objective was to evaluate the composition and functions of the intestinal microbiota in patients with alcohol-decompensated cirrhosis. Fecal samples of 18 patients and 18 healthy controls (HC) were obtained. Microbial composition was characterized by 16S rRNA amplicon sequencing, SCFA quantification was performed by gas chromatography (GC), and metagenomic predictive profiles were analyzed by PICRUSt2. Gut microbiota in the cirrhosis group revealed a significant increase in the pathogenic/pathobionts genera Escherichia/Shigella and Prevotella, a decrease in beneficial bacteria, such as Blautia, Faecalibacterium, and a decreased α-diversity (p < 0.001) compared to HC. Fecal SCFA concentrations were significantly reduced in the cirrhosis group (p < 0.001). PICRUSt2 analysis indicated a decrease in acetyl-CoA fermentation to butyrate, as well as an increase in pathways related to antibiotics resistance, and aromatic amino acid biosynthesis. These metabolic pathways have been poorly described in the progression of alcohol-related decompensated cirrhosis. The gut microbiota of these patients possesses a pathogenic/inflammatory environment; therefore, future strategies to balance intestinal dysbiosis should be implemented. These findings are described for the first time in the population of western Mexico.

Alliin, an Allium sativum Nutraceutical, ReducesMetaflammation Markers in DIO Mice.

Obesity generates a chronic low-grade inflammatory state which promotes oxidativestress and triggers comorbidities. Alliin is the main organosulfur compound in garlic and has beenshown to induce a decrease in the expression of proinflammatory cytokines; its systemic effect onmetabolic parameters and adipose tissue is not yet known, however. After nine weeks of HFD andwith obesity established in C57BL/6 mice, we observed that a daily treatment with alliin for 3.5weeks (15 mg/kg) did not affect body weight, but significantly improved insulin sensitivity andglucose tolerance, both evaluated through a blood glucose monitoring system. Once alliin treatmentwas completed, serum, adipose tissue, and organs of interest related to metabolism were removedfor further analysis. We observed that alliin significantly decreased the size of adipocytes fromepididymal adipose tissue, evaluated via microscopy. A decrease in gene expression and serumprotein levels of the adipocytokines leptin and resistin, as well as decreased serum IL-6concentration, were detected by qRT-PCR and ELISA, respectively. It did not, however, affectmRNA expression of antioxidant enzymes in the liver. Taken altogether, these results indicate thattreatment with alliin reduces metaflammation markers in DIO mice and improves some metabolicparameters without affecting others.

Influencia de la dieta de mujeres mexicanas sobre la calidad nutricional y la presencia de microorganismos benéficos en la leche humana / Influence of the diet of Mexican women on the nutritional quality and the presence of beneficial microorganisms in human milk

Introducción: la leche materna es el primer alimento fundamental de los neonatos y proporciona todas las fuentes de energía, nutrientes y protección inmunológica que necesitan durante sus primeros meses de vida. Lamentablemente, existen circunstancias específicas que implican que la madre no pueda alimentar correctamente a su bebé, ya que las necesidades nutricionales de la madre difieren en cierta medida durante los diversos periodos de la vida, especialmente en la lactancia, ya que se aumentan las necesidades nutricionales debido a la pérdida de nutrientes, primero por el calostro y luego a través de la leche materna. Objetivo: demostrar la influencia de la dieta de mujeres mexicanas sobre la calidad nutricional y la presencia de microorganismos benéficos en la leche humana. Métodos: se llevaron a cabo 70 encuestas descriptivas de nutrición y toma de muestras de leche a mujeres en estado lactante. Las leches fueron sometidas a diversos análisis bromatológicos y microbiológicos para evaluar su calidad nutricional y posible actividad probiótica. Resultados: se demostró que la ingesta de alimentos de la madre influye en la calidad nutricional de la leche. Asimismo, afecta el desarrollo y crecimiento de las bacterias lácticas. Se aislaron e identificaron diversas cepas en leche humana del género Lactobacillus, además de bacterias patógenas como el caso de Lodderomyces elongisporus, entre otros. Conclusiones: la alimentación de las madres se refleja directamente en la calidad nutricional de la leche. Se observó que la cantidad de nutrientes esenciales de la leche, como son los hidratos de carbono, lípidos y proteínas, varían conforme a la alimentación y el ritmo de vida de las madres, así como la disminución significativa de bacterias lácticas con potencial probiótico

Introduction: breast milk is the first fundamental food of newborns and it provides all the sources of energy, nutrients and the immunological protection they need during their first months of life. Unfortunately, there are specific circumstances that imply that the mother cannot feed her baby correctly, since the mother's nutritional needs differ to a certain extent during different periods of life. Especially in breastfeeding, since nutritional needs are increased, due to the loss of nutrients, first by colostrum and then by breast milk. Objective: to demonstrate the influence of the diet of Mexican women on the nutritional quality and the presence of beneficial microorganisms in human milk. Methods: seventy descriptive surveys of nutrition and sampling of milk to women in nursing state were carried out. The milks were subjected to various bromatological and microbiological analyzes to evaluate their nutritional quality and possible probiotic activity. Results: it was shown that the mother's food intake influences the nutritional quality of the milk. Likewise, it affects the development and growth of lactic acid bacteria. Several strains were isolated and identified in human milk of the genus Lactobacillus, as well as pathogenic bacteria such as Lodderomyces elongisporus among others. Conclusions: the mothers' nutrition is directly reflected in the nutritional quality of the milk. It was observed that the amount of essential nutrients of milk such as carbohydrates, lipids and proteins vary according to the diet and life rhythm of the mothers, as well as the significant decrease of lactic bacteria with probiotic potential
