Cheese was supposed to be constipating (this is a myth I still heard all the time as a cheesemonger in the 90s), so comparing it to milk is probably coded language about that. In general, though, "digestible" is usually about "not lard" - I have a comment about it here (http://vintage-ads.livejournal.com/3001759.html?thread=28562591#t28562591). It was just as much a buzzword as anything you might see in food advertising today, although today we're supposed to have better control over health claims. Check out this Google Books ngram comparing digestible, shortening, and lard (https://books.google.com/ngrams/graph?content=digestible%2Cshortening%2Clard&year_start=1800&year_end=2000&corpus=15&smoothing=3&share=&direct_url=t1%3B%2Cdigestible%3B%2Cc0%3B.t1%3B%2Cshortening%3B%2Cc0%3B.t1%3B%2Clard%3B%2Cc0).
