Farms can be beautiful sites that connect us to nature & history & culture, so we want some farms preserved near cities... but keeping high-value land in low-output farms is for agrotourism rather than sustainability, equity or health, so their area should be small. open.substack.com/pub/matthewy...

Farms aren’t nature

Almost three billion people cannot afford a healthy diet

A healthy, nutritious diet is much more expensive than a calorie sufficient one.

Marion Nestle just posted a useful roundup of links about the leaked draft MAHA report here: www.foodpolitics.com/2025/08/http... So far MAHA is playing out somewhat like Italy's right-wing gastronationalism, which distracts food activists with symbolic stuff so as to give industry gets a free hand.

Will Masters@willmasters.bsky.social · 2y ago

My guess is that MAHA will follow the food policy playbook of Italy's right wing, whose defense of tradition is used to stop rules against harmful new foods. In the U.S. we'll be distracted by fights over raw milk & beef tallow, while the real story is rules on sugar & salt. 3/3 PS, about Italy:

Today's U.S. CPI shows grocery price inflation rising and above 2% year-on-year since March 2025, after the period of low grocery price rises in 2023-24. This FRED chart shows rise in grocery inflation (green) vs restaurant meals (red) and the overall CPI (blue): fred.stlouisfed.org/graph/?g=1LgBF

Wholesale prices came in hot in today’s PPI report, but veggies stole the show 🥦📈 Vegetable prices at the wholesale level surged nearly 39% in July. @willmasters.bsky.social & I unpack what’s behind this spike in today's @marketplace.org 🎙️ www.marketplace.org/story/2025/0...

Why are wholesale vegetable prices spiking, and what's that mean for consumers?

About a quarter of the 3.3% price increase recorded by this month’s producer price index was driven by a spike in wholesale prices for veggies.
