In reply to subalpine:
In general, I don't really think there is such as thing as a state of 'enhanced health' that can be achieved by eating special things. If you have a good, sensible diet with loads of fresh fruit and veg and little processed crap, you shouldn't be deficient in anything and you shouldn't have any diet-related health problems (except allergies perhaps).
Once you're healthy, that's it, there's no more you can do. If you want to feel really great all the time, I don't think that can be achieved by diet - it can only be achieved (if it's even possible) by doing all the right things in your life generally: loads of exercise, the right amount of sleep, healthy sex life and relationships/family life, stimulating job offering the just the right amount of challenge (somewhere below between stress and boredom) blah blah. If your life's perfect you're likely to feel great and wake up in the morning wide awake and with a smile on your face thinking "yeah woo hoo I can't wait to get started on another brilliant day", if it's not, you're more likely to feel crap (low energy, no motivation, minor health problems like skin and headaches). And if you have a decent diet, all the other lifestyle stuff will far outweigh any benefits that can be derived from trendy healthfoods.
I don't think you'll agree, but hey, I think it's the truth and it matches my experience.
