(Red beets are the only ones I can't get my mind around.)
The problem is many people don't know how to prepare them in an appetizing way. Many people were raised on vegetables that were boiled until they were just a pile of tasteless mush with most of the vitamins and minerals washed away too.
Steam them (a microwave is best), and then use your imagination as to how to season them with various spices. Even cook up a sauce to serve with them (But not too much, you don't want to over power them with high calorie stuff.)
A bit of Newman's Italian dressing on some steamed veggies is great. Or just use some fresh ground pepper. Pepper is a very healthy choice too.
Here's a little tune to help you appreciate your little green and yellow buddies.
