La calidad del sueño mejora con la edad


Envejecer no parece ser un factor de riesgo para dormir mal, según una encuesta realizada sobre 150.000 americanos por investigadores de la University of Pennsylvania y publicado este mes en 'Sleep'. De hecho, la percepción subjetiva de la calidad del sueño parece mejorar a lo largo de la vida, ya que las personas que ya han cumplido los 80 se quejan menos que el resto de no poder conciliar el sueño.

Para el líder del estudio, Michael Grandner, "los resultados de su trabajo obligan a replantearse todo lo que sabemos en estos momentos sobre el sueño en los mayores, tanto hombres como mujeres", ya que la idea original de esta investigación era demostrar, sobre una amplia muestra, que se duerme peor con la edad.

La encuesta, en la que se preguntó a los participantes sobre problemas de sueño y somnolencia diurna, teniendo en cuenta circunstancias como la raza, los ingresos, el estado de ánimo o la salud general, reveló que los problemas de salud y la depresión estaban asociados con un sueño pobre.

Las mujeres reconocieron sufrir más problemas de sueño y somnolencia diurna que los hombres. Teniendo en cuenta la edad, a excepción de un repunte en los problemas de sueño durante la mediana edad --más pronunciado en mujeres que en hombres--, la calidad del sueño mejoró de forma consistente con el paso del tiempo. Al menos eso era lo que aseguraban los mayores encuestados.

"Incluso si el sueño entre los americanos más mayores fuera realmente peor que en los adultos jóvenes, los sentimientos sobre esta circunstancia mejoran con la edad", señala Grandner, investigador asociado en los Centros del Sueño y la Neurobiología Circadiana de la Perlman School of Medicine, de la University of Pennsylvania.

Brain health. Promising prebiotics and probiotics combination

According to new research, the bacteria in our gut, known as gut microbiota, play an important role in brain injury and healing after a stroke. Taking particular types of prebiotics and probiotics can help with brain injury, inflammation, gut bacteria imbalances, and intestinal health. However, we still don't know whether prebiotics, probiotics, or synbiotics (a combination of both) perform best for particular conditions, or how they operate. In this study, scientists tested a new synbiotic formulation containing multiple strains of probiotics Lactobacillus reuteri UBLRu-87 Lactobacillus plantarum UBLP-40 Lactobacillus rhamnosus UBLR-58 Lactobacillus salivarius UBLS-22 Bifidobacterium breve UBBr-01 and prebiotic fructooligosaccharides (FOS)  FOS are extracted from the blue agave plant and fruits and vegetables such as bananas, onions, chicory root, garlic, asparagus, jícama, and leeks. Some grains and cereals, such as wheat and barley, also contain FOS. The Jerusalem artichoke and ...

Sweetener Reformulated Biscuits: A Step Towards Blood Glucose Control

In a recent study led by Catherine Gibbons from the University of Leeds, the effects of sweetener reformulated biscuits on appetite and endocrine responses in adults with overweight or obesity were evaluated. This study, conducted between 2021 and 2022 in England and France, sheds light on the potential benefits of substituting sucrose with sweeteners like neotame and stevia rebaudioside M (StRebM). The findings suggest that while the reformulated biscuits yielded similar appetite responses compared to sucrose-sweetened ones, they demonstrated a significant advantage in terms of post-meal insulin and glucose levels. Participants consuming biscuits with neotame and StRebM experienced lower postprandial insulin levels compared to those consuming sucrose, indicating a potential positive impact on blood glucose control. This is particularly noteworthy in the context of individuals at risk of developing type 2 diabetes. However, it's essential to acknowledge the limitations highlighted ...
