^AVerification approaches and outcomes measured were verified using publicly available standards. ^BNutrition-related claims include both explicit statements regarding food nutritional quality and implicit associations (e.g., grass-finished or regenerative systems linked to improved nutritional value). Notably, none of the certification schemes listed require routine analytical measurement of food nutrient composition as part of their verification frameworks.
