Recomiendan el uso de fluor en los niños sólo después de los 6 años

Recomiendan no usar el fluor hasta que los dientes del niño no estén formados: "
EUROPA PRESS

Según los resultados de 79 ensayos clínicos con 73.000 niños de todo el mundo.
El desarrollo total de los dientes llega a los seis años.
A esto se añade que, por debajo de los seis años el niño podría desarrollar fluorosis (manchas en los dientes o decoloración).

Investigadores del Cochrane Oral Health Group, con sede en la facultad de Odontología de la Universidad de Manchester, en Reino Unido, aseguran que los niños deben usar pastas de dientes con mucho flúor, de más de 1.000 partes por millón (ppm), para prevenir la caries, aunque está recomendación sólo es aplicable a partir de los 6 años de edad, cuando los dientes ya están totalmente formados.
Según los resultados de su última investigación, en la que se analizaron 79 ensayos clínicos con 73.000 niños de todo el mundo, el uso de dentífricos flurados reduce el riesgo de caries en un 24%, aunque si la cantidad de flúor es de menos de 1.000 ppm, su eficacia es la misma que las pastas de dientes que no incluyen esta sustancia. Actualmente, la concentración de fluoruro en estos productos va desde 100 a 1.400 ppm según la marca.
Sin embargo, estos expertos advierten de que utilizar pasta dental con flúor para cepillar los dientes de un niño de 12 meses puede estar asociado con un mayor riesgo de desarrollar fluorosis leve (decoloración o aparición de manchas en los dientes), un riesgo que persiste hasta los 6 años, edad en que los dientes están terminando de desarrollarse.
Como reconoció la autora de este estudio, Anne-Marie Glenny, 'es muy confuso para los padres saber cómo encontrar el equilibrio adecuado, que se agrava por el hecho de que las diferentes empresas utilizan diferentes concentraciones de fluoruro en las pastas de dientes infantiles'.
En cualquier caso, desde un punto de vista de la salud pública, 'el riesgo de caries dental y sus consecuencias como el dolor y la extracción es mayor que el pequeño riesgo de fluorosis'.

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
