if you want/need to eat meat and have jaw pain, trouble swallowing, or whatever other mouth/throat/tooth stuff, i recommend going against their advice! i marinated stir-fry beef overnight in a marinade of tamari, honey, and grated* ginger and indeed it broke the meat down to an "improper" mushy texture. it was very easy to chew and swallow.
*i tried this same marinade with the ginger in large chunks and it didn't work. it only worked when i grated the ginger.
(i did the ratio of my three marinade ingredients by taste, so i can't report, but remember, you can improvise a marinade and keep tasting and adjusting it as long as you don't add the meat till it's finished.)
