As specific organs reduce functioning, some seniors living at home need to revise their recipes to avoid complex collections of foods just as TIAs and other problems reduce their ability to deal with the challenges. To-go food does not work. For some families, hospital-style food may mimic the diet they are accustomed to, but for immigrants, traditional hospital food may be horrific. Older people tend to rely on a very limited set of dishes, so that custom tailoring recipes may be cost effective. There are dietitian-run food delivery services, but not ones that create meals from clients' recipes. Affluent market tends to live away from their parents. The pain point is my co-worker telling me, "Food is killing my dad, and there is nothing I can do about it unless I quit this job and move home, which would be disastrous for my spouse and kids. As far as I can tell, I have to know how to solve the problem and just sit here, 3,000 miles away, and watch him die." I think this market would pay a premium.
