Dietary habits strongly influence gut microbiota. The aim of this study was to compare and correlated the abundance of Firmicutes and Bacteroidetes phyla, some representative bacteria of these phyla such as Bacteroides thetaiotaomicron, Prevotella, Faecalibacterium prausnitzii, Clostridium leptum and Bifidobacterium longum as a member of Actinobacteria phylum in young adults with their food intake. Faecal samples used came from lean subjects (BMI = 19.83 ± 0.94 kg/m(2)), overweight (BMI = 27.17 ± 0.51 kg/m(2)) and obese (BMI = 41.33 ± 5.25 kg/m(2)). There were significant differences in total studied gut microbiota between the overweight and lean groups. Members of the Firmicutes phylum, and Bifidobacterium longum, were more abundant in the lean group. The results suggest that diet rich in unsaturated fatty acids and fibre promote an abundant population of beneficial bacteria such as B. longum and Bacteroidetes. However, it has been considered that the results may be biased due to the size of the individuals studied; therefore the results could be only valid for the studied population.
The objective of this study was to know the relationship between dietary intake (DI) and body composition (BC) with the metabolic syndrome (MS) among university students. A total of 50 students (56% female) among 19 and 25 years of age (M = 20.58, SD = 1.86), completed a questionnaire aimed at assessing DI, in addition biochemical and BC parameters were collected. According to the percentage of body fat (BF), a high prevalence of overweight (22%) and obesity (38%) was identified. In addition, visceral fat increased as the BF increased. In both sexes, there was a low consumption of carbohydrates and high in lipids, mostly of animal fat as well as high consumption of saturated fats, but low omegas 3 y 6. The MS was identified in 20% of the sample, mainly in women. The most frequently risk criteria were low levels of HDL cholesterol, followed by abdominal obesity; whereas the most frequent dyslipidemia was hypertriglyceridemia. In this study, although no direct relationship was found between DI and MS, it was found between MS and BC indicators. It is imminent the need to implement strategies that allow university students to acquire healthy eating and physical activity habits. Resumen El objetivo de este estudio fue conocer la relación de la ingesta alimentaria (IA) y la composición corporal (CMC) con el síndrome metabólico (SM) entre estudiantes universitarios. Participaron 50 alumnos (56% mujeres) de entre 19 y 25 años de edad (M = 20.58, DE = 1.86), quienes completaron un cuestionario dirigido a evaluar IA, además se recabaron parámetros bioquímicos y de CMC. De acuerdo con el porcentaje de grasa corporal (PG), se identificó una alta ocurrencia de sobrepeso (22%) y obesidad (38%). Además, la grasa visceral incrementó conforme aumentó el PG. En ambos sexos existió un consumo bajo de hidratos de carbono y alto en lípidos, mayormente de origen animal, así como alto consumo de grasas saturadas, pero bajo de omegas 3 y 6. El SM fue identificado en 20% de la muestra, principalmente mujeres. El criterio de riesgo más frecuente fueron bajos niveles séricos de colesterol HDL, seguido de la obesidad abdominal; en tanto que la dislipidemia más frecuente fue la hipertrigliceridemia. En este estudio, aunque no se encontró relación directa entre IA y SM, si de éste con indicadores de CMC. Resulta inminente la necesidad de implementar estrategias que permitan a los estudiantes universitarios adquirir hábitos alimentarios y de actividad física saludables.
Viral infections represent a major health problem worldwide. Due to the wide variety of etiological agents and their increasing resistance to anti-virals and antibiotics treatments, new strategies for effective therapies need to be developed. Scientific evidence suggests that probiotics may have prophylactic and therapeutic effects in viral diseases. Indeed, these microorganisms interact harmoniously with the intestinal microbiota and protect the integrity of the intestinal barrier as well as modulate the host immune system. Currently, clinical trials with probiotics have been documented in respiratory tract infections, infections caused by human immunodeficiency viruses, herpes, human papillomavirus and hepatic encephalopathy. However, the benefits documented so far are difficult to extrapolate, due to the strain-dependent effect. In addition, the dose of the microorganism used as well as host characteristics are other parameters that should be consider when advocating the use of probiotics to treat viral infections. This review addresses the scientific evidence of the efficacy of probiotics in clinical strains perspective in viral infectious diseases in the last 10 years.
