Abstract:
Purified diets offer compositionally defined platforms that improve causal inference in nutrition studies. When aligned with the biological question, they enable targeted nutrient loss- and gain-of-function experiments, systematic lipid-source swaps, and the discovery of diet-microbiome-drug interactions. We recommend complementary validation in grain-based chow or human-relevant diets to maximize translational relevance.
