3 meals and snacks are provided daily, responsibility for eating is up to the individual, only thing is that most people are suffering other health and mental issues and sometimes lose interest in eating.
For many elderly home health care is just not possible, that means nursing homes and although the care is good, there are issues.
I have seen many elderly lose weight to alarming levels, skin and bones at which time health gives out. I am lucky that I can be a part of my mom’s life and make sure she eats almost daily to keep her energy up, not all patients have that available.
