El jugo de arándanos mejora la capacidad de aprendizaje y memoria, según los científicos

Científicos han conseguido la primera evidencia de que los arándanos --una de las fuentes más ricas de los saludables antioxidantes y otros fitoquímicos-- mejoran la memoria. El estudio, publicado en el último número de la revista Journal of Agricultural and Food Chemistry, establece una base para ensayos clínicos en humanos para determinar si los arándanos realmente confirman su creciente reputación como potenciadores de la memoria.

Por Europa Press en Enero 21, 2010. Robert Krikorian y sus colegas partieron de estudios previos en animales de laboratorio que sugieren que la ingesta de arándanos puede ayudar a potenciar la memoria en edades avanzadas. Hasta ahora, sin embargo, había pocos trabajos científicos centrados en comprobar el efecto de suplementos de esta fruta en la memoria de las personas.

En el estudio, un grupo de voluntarios septuagenarios con pérdida de memoria incipiente tomaron el equivalente a 2 o 2,5 vasos diarios de zumo de arándano disponible en tiendas de alimentación durante dos meses. Otro grupo tomó una bebida con otra composición. El grupo del zumo de arándanos mostró una mejora significativa en pruebas de aprendizaje y memoria, según los científicos.

"Estos hallazgos preliminares sobre la memoria son prometedores y sugieren que un suplemento consistente a base de arándanos puede ofrecer una posibilidad de mitigar el proceso neurodegenerativo", señala el estudio. La investigación involucró a científicos de la Universidad de Cincinatti, y los departamentos de Agricultura de Estados Unidos y de Canadá.
Un informe del estudio aparece en el ACS' Journal of Agricultural and Food Chemistry.

Nordic Walking Benefits, ADHD and Diet, Supplements and Cancer, Sources of Fiber

A Better Way To Walk: Nordic Walking Improves Quality of Life, Depression, and Functional Capacity SciTechDaily Reference: “Sustained Effects of Different Exercise Modalities on Physical and Mental Health in Patients With Coronary Artery Disease: A Randomized ... Dietary Interventions for ADHD: Emerging Research and Considerations There has been increasing interest in the role that diet and supplements play in the treatment of attention-deficit/hyperactivity disorder (ADHD) symptoms, from patients and researchers alike. Diet is an important treatment approach to consider, as it is a lifestyle change rather than a medication. Additionally, at least 10% to 30% of children with ADHD are non-responsive to, or experience adverse effects from, ADHD medications.1 A dietary approach to ADHD can be complementary to a conventional pharmacological approach, giving patients and their families more options toward a personalized treatment plan. This article will examine current research about di

More People Are Microdosing for Mental Health. But Does It Work?

By Dana G Smith. Joseph started microdosing psychedelics five years ago to try to improve his mental health. “I was just kind of in this depression, in this rut,” he said. “I was unhappy and angry and agitated all the time, and it went against the way that I saw myself.” Depression and anxiety run in Joseph’s family, and he’d been prescribed Prozac as a kid. But when symptoms of depression returned in his early 30s, he didn’t want to go back to a prescription drug. Joseph, an Austin-based designer (he asked to withhold his full name, citing privacy concerns surrounding mental health issues and illegal drug use), came across research from Johns Hopkins University about psilocybin, the active ingredient in hallucinogenic, or “magic,” mushrooms. In a small study, full doses of the drug helped cancer patients cope with depression and anxiety. Then he read anecdotes of Silicon Valley influencers claiming increased energy from taking tiny doses of psychedelics. So he decided to start microdo

Exploring the Link Between Circadian Rhythms, Longevity, and Wearable Data: Insights and Future Directions

A recent study in NHANES 2011–2014 explores the potential connection between disruptions in circadian rhythms, measured using wearable devices, and their impact on health outcomes and longevity. The study analyzes data from 7,297 U.S. adults collected through wearable accelerometers as a novel digital biomarker for longevity. Five distinct clusters were identified based on activity profiles: "High activity," "Low activity," "Mild circadian rhythm (CR) disruption," "Severe CR disruption," and "Very low activity." The findings reveal that young adults with extreme circadian rhythm disturbance exhibit higher white blood cell counts and accelerated biological aging. Older adults with circadian disruption are associated with increased systemic inflammation indexes, advanced biological aging, and higher all-cause mortality risk. The research underscores the importance of circadian alignment for longevity at all ages and suggests that wearable
