Importance of stomach acid:
1) Proper levels of stomach acid are needed to allow the body to adequately absorb various nutrients, which include: iron, copper, zinc, calcium, vitamin B12, folic acid & proteins.
2) Stomach acid forms a crucial part of the immune system. When the body has optimum levels of stomach acid it acts as a barrier to quickly kill bacteria and bugs that enter the body. It also prevents bacteria in the intestines from migrating up and colonizing the stomach.
The above two factors are crucial as proper nutrient absorption and functioning immune system are vital to total health.
