Interesting post. It reminds me of the Indian practice for seeking to eat all the colors of the rainbow daily to insure good health. That is a pretty good rule to thumb when you are seeking to balance nutrients. At least you tend to get in all the veggies in your diet. Except of course if you ate M&M or Skittles to get the colors.
Do they still make 'Chuckles'? ;-)
Vinegar, carrots, parsley, and garlic every day works for me.
