Some foods just taste bad to me, foods I know are "good" for me. All the cruciforms except steamed broccoli, I can eat that. But cabbage, kale, brussel sprouts ... awful stuff! And most root vegs like you are talking about, rutabagas, parsnips, BEETS... gag! I can do carrots, potatoes, sweet potatoes. And winter squash, I can eat those all day long. Artichokes, yes; av[cadoes, yum! But those others, they burn my mouth. Just .... ick! Lol. Diff'rent strokes, I guess.
