Why do older people have trouble swallowing their food?

Downgrade his diet a little bit. He should eat soft foods and chopped up meats (mechanical soft diet). I am guessing he would have an easier time with things.

The real concern is liquids. If his swallowing has weakened (Very commong with age) he may have trouble getting liquids down and can aspirate (take liquid into his lungs) without knowing it. If this is the case, he would need to have thicker liquids (they are easier to control even with a weak swallow). He really needs to mention this to his doctor. In the meantime, a mechanical soft diet will be much easier for him to eat. Also three small meals and three snacks will allow him to eat less in each sitting, but still get what he needs throughout the day

as you age, your muscle use begins to deteriorate. especially at that age, it is common for swallowing to become a issue.

He should talk to his dr about it. It can become very serious. if you are the one that takes him to the dr appts make sure you bring it up.

also true.
