Regular consumption of functional dairy products offers numerous health benefits, such as anti‐inflammatory and antioxidant effects. This study assessed Brazilian consumers' knowledge and barriers to their consumption using the free comment (FC) method and textual analysis. FC identified 462 descriptors from 332 volunteers, including ‘cheese’, ‘dairy’, ‘health’, ‘probiotic’, ‘nutrients’ and ‘benefits’. Textual analysis organised the data, revealing consumers' knowledge and preferences. The analysis highlighted the need for strategies to address barriers to functional dairy product consumption, focusing on sensory preferences and promoting these products among consumers who currently resist them.
