Yes, a growing body of scientific evidence indicates that high consumption of ultra-processed foods (UPFs) constitutes a significant public health hazard, linked to elevated risks of multiple chronic diseases, obesity, mental health issues, and premature mortality. Experts, including large international teams, describe them as a key driver of the global burden of diet-related diseases and call for

Social media is neither purely more harmful nor more helpful—it's a double-edged sword whose net impact depends heavily on how, how much, by whom, and in what context it is used. Effects are often small on average for the typical adult user, more pronounced (and concerning) for heavy/problematic use and adolescents (especially girls during key developmental periods), and can be positive when focus

Ultra-processed foods and public health — I'll pull the latest evidence on risks and what health agencies are saying. Yes - major health agencies and large reviews of epidemiological evidence increasingly treat diets high in ultra-processed foods (UPFs) as a public health hazard, although there is nuance about heterogeneity within the category. What are Ultra-Processed Foods? The term originat

Is social media a net help or harm? I'll weigh the evidence on both sides. Social media is neither purely harmful nor purely helpful - research shows it has both significant risks and meaningful benefits, and its impact depends on how, why, and by whom it is used. Social media use is not uniformly harmful; its psychological impact depends on how, why, and by whom it is used Overall, social med

Ultra-processed foods are under intense scrutiny — I'll review the latest evidence on whether they pose a public health hazard. Yes - major public health agencies and large reviews of evidence now treat high consumption of ultra-processed foods (UPFs) as a public health hazard, although evidence is nuanced and not all UPFs appear equally harmful. 1. What are ultra-processed foods? The most wid

Social media is a double-edged sword: neither purely more harmful nor purely more helpful overall. Its net effects are highly context-dependent—varying by age, amount and type of use (e.g., active posting/engaging vs. passive scrolling), content consumed, individual vulnerabilities, and platform design. Average effects on well-being are often small or heterogeneous in large meta-analyses, but risk
