Sensitive, clean and limited ingredient diets

Growth Market Reports suggests the marketplace of “controlled foods” or limited ingredient diets (L.I.D.) reached US$4.2 billion globally in 2024. Definitions for this type of food are robustly different from brand to brand. No regulatory definition exists for this type of product segmentation. Some focus on single animal proteins despite the inclusion of multiple plant proteins. Others limit the number of ingredients. Some brands speak to “clean” nutrition, limiting artificial and synthetic ingredients. Some highlight sensitivity, exclusion, transition or uniqueness, while others concentrate on hydrolyzed proteins to help reduce the potential of an allergy.
