Do you children have unsual tastes in food?
DH and I love Thai food and our DS adores Thai green curry, Pad Thai and Thai fishcakes as well as olives (especially stuffed with garlic). We get some funny looks when he asks me for olives while other kids are munching on crisps and sweets.
Bless him, he doesn't know what sweets are and has only had chocolate twice in his life.
