Why Dijon Mustard Is Allowed

Dijon Mustard is classified as Allowed because its composition aligns with the core principles of the Keto diet. Keto is a dietary rule system focused on low-carbohydrate, high-fat intake, with published guidelines that classify foods and ingredients based on net carbohydrate content and macronutrient ratios. As a condiments item, dijon mustard is generally considered compatible with these guidelines. The classification reflects the general consensus based on its ingredient profile and how it fits within the diet's framework.
