Se piensa mejor en el futuro con buenos niveles de azúcar en la sangre, señala estudio


Investigadores de la university of south dakota, en estados unidos, han descubierto que cuando tenemos niveles más altos de glucosa en la sangre (o tenemos más energía disponible en el organismo) tendemos a tomar decisiones más orientadas hacia el futuro. 


En un estudio realizado, los investigadores preguntaron a un grupo de voluntarios, si preferían recibir cierta cantidad de dinero al día siguiente, o una cantidad de dinero mayor más adelante. 


Las preguntas fueron contestadas antes y después de beber bien una bebida azucarada bien una bebida que contenía edulcorantes artificiales. Al inicio del experimento y después de que los voluntarios tomaran estas bebidas se midieron sus niveles de glucosa en sangre. 







Los resultados obtenidos demostraron que las preferencias de la gente por recibir la recompensa antes o después estaban relacionadas con el nivel de glucosa en sangre. Así, los voluntarios que tomaron la bebida con azúcar tendieron más a elegir recibir más dinero más tarde que el resto de los participantes en la prueba. 


Según los científicos, esto se debe a que el futuro es más abstracto que el presente y, por tanto, para reflexionar sobre él nuestro cerebro requiere una mayor cantidad de energía. La glucosa en sangre, como combustible cerebral, podría así fortalecer la capacidad de procesar procesos cognitivos relacionados con eventos futuros.

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 ...
