Descubren por qué una manzana al día es buena para la salud

Un estudio encuentra que las bacterias intestinales beneficiosas se podrían beneficiar de la fruta

MIÉRCOLES, 20 de enero (HealthDay News/DrTango) -- La sabiduría popular afirma que las manzanas son un refrigerio saludable. Un estudio reciente la respalda, al encontrar que un componente de la fruta, llamado pectina, aumenta los niveles de gérmenes amigables en el sistema digestivo.

Microbiólogos del Instituto Nacional de Alimentos de la Universidad de Dinamarca evaluaron el efecto del consumo de manzanas al alimentar ratas con una dieta de manzanas enteras además de productos derivados de la fruta, como jugo y puré de manzana.

Entonces, los investigadores revisaron las bacterias en los intestinos de las ratas para determinar si consumir manzanas afectaba los niveles de bacterias "amigables", que son bacterias que resultan beneficiosas para la salud digestiva y que podrían reducir el riesgo de ciertas enfermedades.

Los hallazgos del estudio aparecen en línea el 20 de enero en la revista BMC Microbiology.

"En nuestro estudio, encontramos que las ratas que comían una dieta rica en pectina, un componente de la fibra dietética de las manzanas, tenían mayores cantidades de ciertas bacterias que podrían mejorar la salud intestinal", aseguraron en un comunicado de prensa del editor de la revista el coinvestigador del estudio Andrea Wilcks.

"Parece que cuando se comen manzanas de forma regular y durante periodos prolongados, estas bacterias ayudan a producir ácidos grasos de cadena corta que proveen condiciones de pH ideales para asegurar un equilibrio beneficioso de microorganismos. También producen una sustancia química llamada butirato, que es un importante combustible para las células de la pared intestinal", añadió Wicks.

Los autores del estudio señalaron que se necesita más información para determinar si los hallazgos en las ratas se aplican a los humanos.

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
