Headline reading "at least 89% of mass shootings were perpetrated by men."

Headline reading "at least 89% of mass shootings were perpetrated by men."

A reminder, on the day following another mass shooting: it's a gun problem, and it's a masculinity problem.

Framing instances of gun violence largely as a domestic issue or a mental health issue ignores these glaring truths. wapo.st/3QQEH6Y

AI scribes suck. Check your clinical notes, everyone! I’ve had them cite the wrong body part (left vs right) for surgery, state that I have a diagnosis that I’d specifically said I do NOT have, mistranscribe my symptom descriptions, and more! Genuinely dangerous for so many reasons.

The MAHA Dietary Guidelines I: Personal Responsibility vs. Public Health Policy This is the first of a series of posts I will be writing about the new Dietary Guidelines for America, 2025-2030 Yesterday, I gave an overview of the guidelines, finding them cheerful, but muddled, contradictory, ideological, and retro. I do like the cheerful message: Eat Real Food. But after reviewing lsome of the rest of the materials that come with the guidelines, I think those terms miss a more important concern: they are about personal responsibility, not public health.

How saturated fats lost, and won, on new food pyramid New dietary guidelines limit saturated fats to 10% of total calories, but also encourage full-fat dairy, red meat, and beef tallow. How will that work?

“The recommendation to limit saturated fats remains intact. Yet the guidelines also encourage people to eat foods higher in saturated fats… “It’s almost laughable that they kept the 10% limit for saturated fat while really pushing red meat and dairy… Good luck trying to circle that square.”
