As one particular example, in order to digest protein into amino acids in the gut, the enzyme protease is required. These smaller amino acids, and peptides then are allowed to pass from the gut into the portal vein and into the body. Now, let's look at a little old lady who virtually lives on white bread toast and tea. She is using up her protein in constantly re-building cells, and losing some in that process. This vicious circle happens much more than we realize.

In several cases I worked with, while in active practice, I was able to reverse senility and some of these had been diagnosed with Alzheimer's. In my opinion, senility isn't inevitable from aging.
