Well i am flying frm US to asia withstopover in switzerland and want to knw if i can fill my cabbin baggage with chocolates (All packed by their respective brands)... I mean if food is allowed ?

Ru sure there is no restriction on these ?

I don't know about importing to Asia, but I have never had a problem with chocolate in the carry on. I would just not choose anything that's filled with liquids (such as certain pralines).
Good flight
