I've been astounded at the problems I thought were unrelated to food/health that have gone away with dietary changes. Things I didn't even realize I had issue with due to health stopped being an issue. For example, I used to hate a lot of chores, such as doing dishes in particular. I thought I hated these things because they were boring, unfun, time consuming, etc, and took me away from things that I enjoyed. This was not the case. The problem was that most chores required me to do things that caused me discomfort in my body. I didn't realize how strong that discomfort was until it was finally relieved. Now I find chores merely boring, or unexciting, but I no longer hate them.
A common theme among people who become raw foodists is the discovery that almost every problem is a health problem. One really common statement I hear from raw vegans is: "I can't believe how much my mood is lifted, I used to always be depressed!"
People who are spiritual who become raw vegans say things like, "It's easier to meditate longer, and get deeper into the meditation." People who are into sports say things like, "It's incredible how much more focused I am on the game, and how much harder I can play." And people who sing say, "My voice is so much cleaner/stronger/clearer!" and people into yoga say, "My balance is so much better," etc, etc, etc.
But even more incredible is how often people find that poor relationships dissolve and disappear, and decent/good relationships become incredible. In other words, being healthier separates you from bad relationships, and connects you deeper into good relationships. It's priceless.
Memory often improves after a really good detox, but just changing a few food items a day won't create a powerful enough detox for that. In any event, my point is, emotional/spiritual/social/mental issues are all greatly reduced or completely resolved through detoxification of the body, and this is often not understood or known.
