Can you (or anyone) point to evidence to support this. Just interested, I know a raw foodie or two who would be interested. ta I cant comment on the blender, however i remembered reading a study from England studying the effects of the raw veggie diet. I don´t quite remember the result but it was quite varied. The only link i found to that study was sadly dead so here are a few other studies i found regarding this subject. While searching though i found this on Pubmed. Its kind of strange. http://www.ncbi.nlm.nih.gov/pubmed/19083456 Then upon further research i found this. http://pubs.acs.org/doi/abs/10.1021/jf072304b?prevSearch=boiling+frying+steaming&searchHistoryKey= I cant really draw any conclusions but it seems that if its generally nutrients you are after then some kind of cooking is the way to go. Quite frankly it might depend on what you want, i don´t really think its going to make a big difference either way though. When looking around on the raw food sites i found mostly un testable claims like - The life essence of the carrot is lost while cooking it, that´s not something i can address as its not an observed thing. I saw a man talking about enzymes, they were talking about scary things like a cure for cancer and boosting the immune system. Things that they have no way to back up. Its also very dangerous. Of course these were the scariest parts. Most people just claimed it was "Better" and did not really quantify it more than that. Thanks for your time and i hope this helped.
