Nature's editorial board advocates for the UN's trans fat elimination proposal to specifically target "industrially produced" fats, warning against unintended negative impacts on nutrition in developing nations. They support a coalition's call for this clarification, as natural trans fats are present in dairy products. The editorial also critiques the current ultra-processed foods classification, exemplified by the NOVA scale, for its broad grouping of dissimilar items like baby formula and hot dogs. Nature urges for refined definitions that curb excesses in industrial food production without jeopardizing global access to sufficient calories.
