Seguir una dieta rica en plantas de alta calidad que incluya cereales integrales, verduras y frutas puede prevenir el deterioro cognitivo, incluso cuando las personas comienzan esa dieta a finales de los 50 y en sus 60, de acuerdo con un nuevo estudio.

“Nunca es demasiado tarde para empezar a comer sano para reducir el riesgo de la enfermedad de Alzheimer y las demencias relacionadas”, dijo la autora principal, Unhee Lim, profesora de ciencias poblacionales en el University of Hawaii Cancer Center en Honolulu, en un correo electrónico.

Los adultos mayores que eliminaron muchos alimentos poco saludables de su dieta a lo largo de una década tuvieron un 11 % menos de riesgo de Alzheimer y demencia en comparación con los adultos cuyas dietas no cambiaron, aseguró Lim.

Sin embargo, las personas que cada vez consumieron más opciones vegetales poco saludables, como granos refinados y alimentos con azúcares añadidos, tuvieron aproximadamente un 25 % más de probabilidades de desarrollar algún tipo de demencia al final de 10 años, dijo.

“Los hallazgos sugieren que tanto una alimentación predominantemente vegetal como una alta calidad de la dieta ayudan a proteger la función cerebral a medida que envejecemos”, dijo el Dr. David Katz, especialista en medicina preventiva y del estilo de vida que no participó en el estudio. Katz fundó la organización sin fines de lucro True Health Initiative, una coalición global de expertos dedicada a la medicina del estilo de vida basada en la evidencia.

La definición básica de una dieta basada en plantas es amplia, y simplemente requiere que una persona priorice comer más alimentos vegetales que productos de origen animal como carne, leche y huevos. Bajo ese paraguas, una persona podría llamarse vegana y aun así subsistir con alimentos ultraprocesados azucarados y ricos en grasa, conocidos por perjudicar la salud.

El desayuno, por ejemplo, podría ser un waffle o panqueque congelado ultraprocesado con miel de maple falsa. El almuerzo podría incluir una hamburguesa vegetariana de comida rápida alta en sodio, papas fritas o aros de cebolla chorreando grasa saturada, y una gaseosa con sabor a fruta repleta de azúcar. La cena podría incluir pasta de harina blanca de grano refinado con salsa de tomate alta en azúcar, seguida de galletas o pastel ultraprocesados, todo a base de plantas, pero nada bueno para la salud de tu cerebro.

El nuevo informe, publicado este miércoles en la revista Neurology, intentó desentrañar cómo la calidad de una dieta basada en plantas afectaría el riesgo de demencia. El estudio incluyó a casi 93.000 personas con una edad promedio de 59 años y una mezcla diversa de etnias: afroamericana, japonesa estadounidense, latina, nativa hawaiana y blanca. A todos los participantes se les preguntó sobre sus dietas al inicio del estudio. Diez años después, un grupo más pequeño de poco más de 45.000 personas informó sobre su dieta por segunda vez.

El equipo de investigación calificó las dietas en tres niveles de calidad. Comer grasas animales saturadas, lácteos, huevos, mariscos y carne fue el nivel más bajo. Un nivel superior fue el de alimentos vegetales menos saludables, como granos refinados, jugos de fruta, papas y azúcares añadidos.

¿Por qué los jugos de fruta y las papas se consideran menos saludables? Las papas son altas en almidón, que rápidamente se convierte en glucosa en la sangre, lo que potencialmente desencadena picos de azúcar en sangre. Además, freír papas o agregar crema agria y mantequilla añade calorías excesivas, grasas poco saludables y sodio.

(CNN) — A North Carolina woman has been charged with sharing classified defense information to a journalist following her work as a civilian operational support technician at Fort Bragg, a large US Army base in the state.

Courtney Williams worked in a Special Military Unit from 2010 to 2016 and had top secret clearance with access to a significant amount of classified material, charging documents say.

Federal prosecutors allege that from 2022 to 2025, Williams shared classified information that the journalist used in reporting for an article and book on Fort Bragg.

While court records do not name the journalist, a book “The Fort Bragg Cartel” and magazine article from independent reporter Seth Harp last year, profiles Williams and her allegations of harassment and abuse while employed at Fort Bragg.

With scant details, charging documents allege that information shared by Williams to the reporter included classified information she was not allowed to provide.

CNN is attempting to contact Williams’ attorney.

Harp’s article details the significant sexual and race-based harassment Williams says she saw and, at times, experienced during her work at the North Carolina army base.

According to the Justice Department, on the day the book and article were released, “Williams exchanged several messages with the Journalist” and said she was “concerned about the amount of classified information being disclosed.”

In a conversation with her mother, according to the indictment, Williams said, “I might actually get arrested, and I don’t even get a free copy of the book.”

(CNN) — President Trump opened Easter Sunday with a florid threat toward Iran, decked in profanities and obscenities.

“Tuesday will be Power Plant Day, and Bridge Day, all wrapped up in one, in Iran. There will be nothing like it!!!” he wrote on his social media platform Truth Social. “Open the Fuckin’ Strait, you crazy bastards, or you’ll be living in Hell – JUST WATCH! Praise be to Allah.”

There was a lot for journalists to analyze in Trump’s statement: He vowed to inflict suffering, threatened to commit war crimes and mocked Muslims on the holiest day for Christians. But in reporting on the remarks, the news media was confronted with another, more narrow issue: how to address the president’s use of “Fuckin’.”

“Fuckin’” is a colloquial shortening of the present participle of the verb “fuck,” which comes from the Germanic languages — though it’s unclear which language specifically, the lexicographer and linguist Jesse Sheidlower writes in “The F-Word.” His book notes that the English word is related to Dutch, German and Swedish words meaning “to copulate” or “to move back and forth.” In the 14th century, it appeared for the first time in court records about a man named Roger Fuckebythenavele. A subsequent, non-name appearance in the 15th century is obscured by a cipher, Sheidlower writes, suggesting that it was strongly taboo.

The ambiguity around the word’s origins stems at least partly from a centuries-long moral panic over it, says Michael Adams, an English professor at Indiana University Bloomington who has written about swearing. The word was considered so vulgar that it was left out of early dictionaries and was rarely printed, though Adams says people were certainly using it. Originally used in sexual senses, by the late 1800s, it had become an intensifier — as in, “fucking hell” or, later, “abso-fucking-lutely.”

“It’s a word that’s had a private life and not a public one,” Adams says. “And now it has a public one as well.”

Today, the word and its variants are ubiquitous and less taboo than ever. They are deployed for emphasis or humor, as well as to express shock, anger, frustration or even joy, as when Olympic figure skater Alysa Liu turned to the camera and microphone and declared “That’s what I’m fuckin’ talkin’ about!” after the performance that won her the gold medal.

Despite such widespread use, major news organizations still refrain from publishing or airing profanity except in rare cases. For primetime rebroadcast, NBC cut out Liu’s audio between “I’m” and “talkin’.”

When is profanity essential to a story? The president of the United States using it publicly to threaten Iran appears to be one such case. But while “Fuckin’” appeared in online articles largely as Trump expressed it, it was at times censored and uncensored on TV.

Most major news organizations avoided putting it in print and digital headlines, opting for broad characterizations such as “curse-filled” or “expletive-laden.” The New York Times and The Wall Street Journal also wrote around the word in their print stories, though The Washington Post included it in full. Still, most outlets used the word plainly in the body of their online stories: Read more
