> I’ve never heard one that involves women liking sweet food more or less than men,
It's somewhat ingrained in (traditional) Japanese culture that women prefer sweet foods and men prefer spicy foods. Young boys enjoying sweets is seen as "funny" since they don't "know" it's a feminine thing yet (not necessarily in a "you can't do that" way, but more in a "cute that he hasn't picked up on it yet" way).
