I’m 80 and I eat a lot less now, am I getting enough nutrients?

DEAR DOCTOR K: I'm in my 80s. These days, I'm not very hungry and I eat a lot less than I used to. My daughter is worried I'm not getting enough nutrients. Is she right?
DEAR READER: Of course, I don't know if you are getting enough nutrients, but your daughter is right to be worried about it. For one thing, you say you're not eating much. People normally start to have a reduced appetite as they get into their 70s and 80s, but it's not a dramatic change.
