N. Walker cut bodies open and saw it

dr. norman walker, the godfather of the modern day health movement, was present at hundreds of autopsies where he personally saw mucoid plaque build up. it was the cornerstone of his health philosophy - clean out those bowels!! he believed that nearly every physical ailment could be cured by cleaning out the bowels and eating fresh raw food and drinking fresh juice.

he was the first person to manufacture a machine dedicated to juicing fruits and vegetables, and lived to be a healthy and vibrant 109 years old.
