Yes — the scientific and public-health consensus has shifted strongly toward viewing ultra-processed foods (UPFs) as a genuine public health hazard, and the evidence supporting this has grown substantially stronger in the last two years. The scale of the problem UPFs now dominate diets in many countries. UPF currently make up more than half of what U.S. adults eat on a daily basis, and two-thir

Yes — overall, electric vehicles (EVs) have a lower environmental footprint than gas-powered vehicles, though the picture is nuanced.

According to the International Council on Clean Transportation (ICCT), emissions over the lifetime of average medium-size battery electric

Yes, a growing and increasingly authoritative body of scientific evidence indicates that ultra-processed foods (UPFs) represent a genuine public health hazard, though some scientists urge nuance about how the category is defined and used.

The key nu

Ultra-Processed Foods: A Public Health Hazard? Based on the latest scientific evidence, there is a strong and growing consensus among researchers that yes, ultra-processed foods (UPFs) represent a significant public health hazard, though some scientific debate remains about mechanisms and precision of the term. The Evidence Is Substantial and Growing A major 2025 Lancet Series brought togethe

Short answer: Yes, by most measures — though there's important nuance depending on the timeframe and what kind of polarization you mean. Congress/elite polarization By the numbers, today's polarization in Congress is historically extreme, at least for the modern era. A Pew Research Center analysis finds that, on average, Democrats and Republicans are farther apart ideologically today than at an

Short answer: Yes — with important nuances The evidence base has grown substantially, and as of late 2025 there's a strong scientific consensus that ultra-processed foods (UPFs), as a category, pose a genuine public health risk — though not every food classified as "ultra-processed" is equally harmful. What counts as a UPF UPFs are defined by the NOVA classification system, which sorts foods
