In my opinion, I think that diet is important for every process in your body, including PE. Our closest ancestor’s bodies did not evolve and develop to eat the processed food that we have all come to know, love and become addicted to. (Yes addicted). Surprisingly enough, the bacteria in our intestinal tract outnumbers the number of cells that make up our entire body. These cells have more impact on how your body reacts than you realize. They cause your craving for food, and have even been linked to concentration and circulation. Long story short, by eating a more organic simple diet like our ancestors had, including many more raw and cooked greens, our bodies will function in the way they evolved to do. This mean, better metabolism, faster healing, better circulation, concentration, etc. Just a thought.
