Bile does not interfere with vitamin A absorption because it plays a crucial role in the emulsification and digestion of dietary fats, which are essential for the absorption of fat-soluble vitamins, including vitamin A. Bile salts facilitate the formation of micelles, allowing vitamin A to be incorporated into these structures and absorbed efficiently in the intestines. Additionally, the presence of bile aids in solubilizing vitamin A, enhancing its bioavailability rather than hindering its absorption. Thus, rather than interfering, bile is vital for the proper uptake of vitamin A.

Examples of such diseases are celiac disease (chronic nutritional disorder), cystic fibrosis, and cholestasis (bile-flow failure or interference).
