Always 1 or 2 or more coughs after eating. Could this be normal?

Years ago I started to cough after eating, no matter what I ate. I will cough 1, 2 or more times. I feels good, no pain at all. It feels like the feeling after you have a cold and have a good, loud productive cough. It's not bothersome but I'm wondering what it could be. It doesn't seem to be related to stomach acids or anything. It seems to be a reaction of eating, like first saliva, then all the other processes, including maybe a bit of congestion in the lungs? I don't know. Any idea?
