Diet Ratings
Duck fat is pure rendered poultry fat with zero carbs and zero protein. Composition is ~35% monounsaturated, ~24% polyunsaturated, ~35% saturated fat. High smoke point (375°F) and exceptional flavor make it a premium keto cooking fat. Nutrient-dense and satiating.
Animal fat derived from duck meat. Direct animal product explicitly excluded by all vegan standards.
Duck fat is rendered animal fat from a wild game bird, perfectly aligned with paleo principles. High in monounsaturated fats and fat-soluble vitamins. Unprocessed and available to hunter-gatherers.
