Thanks to David Introcaso @HealthcareIssue for deep-dive Q&A – at Somerville, MA
This talk on Food Prices for Nutrition is my best effort at a quick and entertaining summary of how & why @FAOstatistics, @worldbankdata, @NBS_Nigeria and others measure the Cost and Affordability of Healthy Diets, and what results imply for food choices

📢Attention policy people out there!
👉Join @FAO next Tuesday, 10 February 2026 at 3pm (CET/Rome time) as we take a major new step in scaling up country support to monitor – and hopefully lower – the Cost & Affordability of a Healthy Diet (CoAHD) at the national level.

Thanks to Pablo Rosado of @OurWorldInData for a clear, vivid explanation of what #FoodPricesForNutrition metrics reveal about healthy diet costs and affordability. The best visualizations of results through 2024:

Just posted, a brief & clear memo from @EconoFactOrg by @dwschanz on why the @USDA food security questionnaire is needed.
The government's statement about why they plan to stop data collection is even shorter:

Big new paper in @AJCNutrition shows limits to the common belief that healthy & sustainable foods are more expensive than other options.

This year's #AAEA2025 coincides with launch of the UN system's #SOFI2025 report on The State of Food Security and Nutrition in the World. Beyond diet costs and affordability, this year's data includes new work on relative cost of nutritional food groups

This week's launch of #SOFI2025 marks the 4th annual update of global diet cost and affordability data, used by UN agencies and national governments as a clear and actionable new metric of global food security.

Will Masters (@WAMasters) of Tufts University shows how a well-crafted indicator (in this case, the lowest cost of a healthy diet) can actively inform civil society discussion.

Latest on #FoodPricesForNutrition, a review article for the 50th anniversary of @_Food_Policy on rapid adoption since 2020 of least-cost diets for monitoring food access, globally by @FAO & @WorldBank or in countries by @NBS_Nigeria, @EPHIEthiopia etc.:

What can we learn from food economics?
Last month on VoxDev, @wamasters @tuftsnutrition & @ameliafinaret @alleghenycol spoke to @timsvengali about their new, open access textbook on Food Economics and what we can learn from the subject:

Our new #Fellowships from @ANH_Academy offer a year of funding to bring recent #research into #policy decisions in #SubSaharanAfrica or #SouthAsia, via placement in a policy-making organization. Aim is healthier diets, less loss & waste + climate & equity.
