Commentary for Berakhot 75:11

א"ל אביי ואת לא תסברא והא תנן כל האוכלין אוכל אדם לרפואה בשבת וכל המשקין שותה אלא מה אית לך למימר גברא לאכילה קא מכוין ה"נ גברא לאכילה קא מכוין

Abbai said to him : Art thou not of the opinion [that it is permitted to compound a remedy on the Sabbath] ? Lo, there is a Mishnaic teaching : All foods may be eaten as a remedy, and likewise all liquids may be drunk ! What is there for thee to say? The man intended it as a food [and therefore it may be prepared on the Sabbath] ; so here also [in the case of the Shattit] the man intended it as a food.
