Seems like the problem is how people were eating before. If people grow up eating something like the Maker's diet (or another great eating plan) then they might not need to cleanse. But to make up for the junk... People cleanse their outside, why not their inside? I like that argument. Anyway, remember that if you do Liver Cleansing you'll need to do a series of flushes not just one or two. Definitely switching to TMD is a good move, cleansing or not, though.
