Does diet make that much difference?
I really don't know why I am asking this, except for my own information, as mil is not going to change anything.
Background is that fil has Parkinsons. A doctor a few years ago told them that at his age, it's not going to make any difference what he eats, so eat what he wants. And he does, just like he has always done. It's coffee and cookies for breakfast, Dr. Pepper and a sandwich for lunch, go out to eat at dinner, or a hamburger casserole (heavy on the salt) at home, and ice cream several times a day. Snacks are cakes, cookies, and peanuts.
No fruit, no fresh vegetables, canned green beans if anything, but mostly carrots and potatoes.
