What could be causing this? any ideas? - Fruit

When I eat fruit, mainly something sweet like apples or grapes, I get a blocked nose. It clears again after an hour or 2.

Things like berries don't appear to do it.

It also affects the tubes in my ears and I can feel them full + popping too.

Could the sugar in these fruits be causing it in some strange way?

I dont think it is an allergy as nothing else is affected just the nose / ear tubes.

Appreciate any possible pointers

Perhaps you are not tolerating fruits with excess polyols or fructose? Check a FODMAPS chart for help clarifying this.

Apples and grapes are known to have the highest BRIX of all commonly available fruits. That's why they make alcoholic beverages out of them. Try figs, also high BRIX, and see if that confirms it. The other option is malic acid, dominant in apples (malus=apple) but also the most abundant acid in grapes. Proper wine fermentation requires secondary fermentation of some malic acid to acquire a rounded flavor (malolactic fermentation).
