I think if / when you get to 80 you earn the right to eat whatever you damn well please......after all at that age it’s not what you’re eating now that’s gonna hurt you if at all.....it’s what you ate for the last 60 years.
Doctors don’t know it all.
I’m 71 and that’s pretty much my philosophy now. I work to keep my weight down and stay (somewhat) fit, plus still eat lots of fruit and veggies. But I’ve relaxed a lot of dietary areas.
