My husband loathes beets. When we were first married, I served beets for dinner and he went into a major sulk. Turned out he assumed I would know that beets are vile and that it is an insult to be served them.
One summer I grew beets to have for my own lunches, but he objected to the way the house smelled from the cooking.
Later I read in a book that this hatred for beets is a rather common phenonenon in males. I can only conclude that they must taste and smell different to different people.
A wise host or hostess would check with guests before serving them beets.
