Public health and food.
School meals reach hundreds of millions of children and work at once as nutrition policy, education policy, social protection and a guaranteed market for local farmers. This piece explains why they are the rare food policy where health, farmer income and equity point the same way, and which contract terms decide whether the benefits materialise.
A large share of the world's antibiotics goes to livestock and aquaculture, and resistance genes travel from farms to people through food, water and soil. This piece argues that drug resistance cannot be solved inside hospitals alone, and examines Europe's experience cutting farm use, the role of vaccines and husbandry, and the reality in places with almost no vets.
Regulators, researchers and food companies are contesting what counts as ultra-processed food, because whatever the definition captures decides what gets labelled, taxed, restricted in school meals or marketed. This piece traces how the NOVA research category became a legal one, what the evidence on health outcomes does and does not show, and what a workable definition could look like.
The Planetary Health Diet's 2025 update estimates it could prevent 15 million premature deaths a year while cutting agricultural emissions by more than half. This piece examines the evidence behind that claim, the backlash it has drawn from the meat industry, and how realistic a global dietary shift of that scale actually is.
A farmer in Punjab can grow enough wheat to feed several families and still leave a child short of the zinc and iron her body needs. This piece explains why food security policy built around calorie counts has failed to catch the hidden micronutrient deficiencies affecting billions, and what a nutrition-first approach to food security would require.
A 2025 UN report found that roughly a third of the world's population cannot afford a healthy diet, with floods, droughts, and erratic rainfall named as active drivers pushing nutrient-dense food out of reach even where staple grain supplies look stable. This piece examines how the climate-hunger conversation is shifting from calorie counting to nutrient security.
A bowl of rice grown under 2050's atmosphere will look and taste identical to today's, while carrying meaningfully less protein and fewer micronutrients. This piece traces the research, beginning with Samuel Myers's landmark 2014 Nature study, documenting how elevated carbon dioxide is silently eroding the nutritional value of the crops billions of people depend on.
