La dieta mediterránea ayuda a proteger al cerebro que envejece

Un estudio encuentra que las personas que puntuaron más alto en el cumplimiento de la dieta eran las menos propensas a sufrir un declive en las habilidades del pensamiento.

Robert Preidt. MARTES, 27 de abril (HealthDay News/DrTango) -- Una dieta mediterránea podría ayudar a mantener su cerebro sano mientras envejece, según hallazgos de un estudio continuo.

"Esta dieta enfatiza la ingesta de verduras, frutas, pescado, aceite de oliva, un menor consumo de carne, vino con moderación y granos no refinados", señaló en un comunicado de prensa de la American Society for Nutrition la Dra. Christy Tangney, autora principal, del Centro Médico de la Universidad de Rush, en Chicago.

En lugar de pedir a la gente que evite ciertos alimentos, el estudio encontró datos de que "los adultos mayores de 65 años deben incluir más aceite de oliva, legumbres, frutos secos y semillas en su dieta para mejorar sus periodos de recuerdo y otras habilidades cognitivas, como identificar símbolos y números", apuntó Tangney.

En el estudio participaron 4,000 adultos de 65 años o más a quienes se dio una serie de pruebas para examinar sus habilidades cognitivas (o del pensamiento) cada tres años durante un periodo de quince años. Los que puntuaron más alto en el seguimiento de una dieta mediterránea eran los menos propensos a sufrir declive cognitivo, según encontraron los autores del estudio.

"[También] queremos que los adultos mayores recuerden que la actividad física es una parte importante del mantenimiento de sus habilidades cognitivas", añadió Tangney.

Se tenía programado presentar los hallazgos el lunes en la reunión de Biología Experimental 2010 en Anaheim, California.

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 ...

Catch of the Day: Hypnosis, Fibromyalgia, IBD, Gut Microbiota, Aging

Hypnosis as a Tool for Managing Fibromyalgia Pain "Harnessing Hypnosis: A Promising Approach to Tackle Fibromyalgia Pain" Fibromyalgia syndrome (FMS) is a complex condition characterized by widespread musculoskeletal pain, fatigue, sleep disturbances, and emotional challenges. The exact cause of FMS is not fully understood, but there's evidence suggesting a link between childhood/adulthood abuse or neglect and its development. Treating FMS can be difficult due to its resistance to most treatments. However, a recent review suggests that hypnotherapy, a psychological intervention, could be effective in managing FMS pain. This technique aims to reduce pain, fatigue, sleep problems, anxiety, and depression by using hypnosis to address emotional conflicts and unresolved traumas associated with FMS. This non-invasive approach might offer relief to those struggling with fibromyalgia. De Benedittis G. The Challenge of Fibromyalgia Efficacy of Hypnosis in Alleviating the Invisibl...
