Health is Wealth: The Alkaline Paleo Diet for Prosperity
Yet our stomachs are even more acidic around 0.7 pH, for digestion of carbohydrates. Our intestines can have very alkaline bile up to 8.8 pH in places to better digest protein. Our urine is acidic with uric acid, around 6 pH. How do our bodies handle these acid/alkaline extremes?
Gastric or intestinal cells can be replaced every five days, the skin every 14 days, the red blood cells every 120 days, the liver every year, the skeleton every decade and the muscle of Adam’s gut and rib every 15 years.
Scientists are investigating the cells of the ocular lens, brain and heart with DNA containing radioactive Carbon14, which may be replaced much more slowly if at all.

Scientists are also using stem cells to regrow body parts like a jaw inside the host body in seven months:

This brings up Locke’s Socks, Plato’s Carriage, the Ship of Theseus and Washington’s Axe.
Wise people asked a long time ago: if we replace the atoms, molecules, cells and parts of our body, are we still be the same person?
Endocrinologist MD Deepak Chopra, Ayurvedic Transcendental Meditation and former Medical Chief of Staff of New England Memorial Hospital and Boston Regional Medical Center, asked how is it that cells replace themselves but disease can continue?

Acid-Alkaline medical theory may go back four millennia to Vedic times in India and later the four humours of Hippocrates, the father of modern medicine, in ancient Greece.
