Burping usually isn't from the food being digested by bacteria to produce gas.But sometimes how much air you swallow with different foods, or something else about the food might make you burpy afterwards, so there could be some association with nuts (assuming that the symptoms are quite different when the only thing you change is removing nuts from the diet)Does it matter if they are salted, or un-salted? Not sure why one might be different, but it might be something to test out.If it seems that the fat in the nuts might be what is making it easier to go you could try adding olive oil to a meal (or take flax-seed oil supplements) and see if that helps without the burping issue.Sometimes things like acid reflux or other stomach problems are involved with this sort of thing, so you might need that checked out.One other thing....sometimes with some medications I get that overly full stomach burping bloating thing (but seems to be all foods). Digestive enzyme supplements with pancreatic enzymes in that seemed to help for me. It might be something to try.K.
