Am I the only one who finds a diet free from all processed foods leads to a clear mind. It has been an almost awakening for me over the course of the last year. My entire view of government and media has changed to be specific. The more you study and learn the scarier reality becomes.
Interestingly, old Taoist monks warned against eating grains.
They maintained that grains clouded the mind and shortened life (some Taoist practitioners were obsessed with immortality and practiced alchemy in the attempt to live forever).
Personally, my mind feels more open and ready, especially in the mornings.
My sensitivity to myself and my true needs has improved. The "Second Brain" in the stomach speaks more clearly now...
I find that I am more anxious when I let my diet slip. I never realized I was anxious until it got better. It was about two weeks in to Paleo.
It isn't the having attacks sort of anxiety just being worried and less adaptable, more likely to find things difficult.
I don't really notice much of a change. Before Paleo, I felt my mind was as good as it ever was. Then I switched to low-carb and that clouded my mind for a month. I felt slightly more tired than usual and had some short-term memory issues. Now on paleo, I feel about where I used to be but maybe very slightly more likely to have a "tip of the tongue" moment, and more tired at night. So, I wouldn't say there's been an increase in clarity. The last thing I can say probably did that for me was going on fish oil when I'd been fishless for years.
