I have a pretty extensive reading list I will upload sometime soon into this mailing list. Most raw foods can be considered mucusless. Exploring the Hippocrates approach and the Natural Hygiene approach are very similar to Ehret's philosophies... However, I personally consider the Hippocrates Health Institute's philosophy much more well-rounded. Robert Gray's _Colon Health Handbook_ is a pure delight for someone wanting to learn more about the mucusless diet in particular. I have found few books more inspiring on this particular subject (of mucusless diet).
