Proper acidic digestion in the stomach:
1. increases nutrient absorption in the small intestine.
2. Kills harmful viruses and organisms, while increasing the ratio of acidophilus to acidophobic organisms among the few survivors. Harmful organisms that are not killed by strong stomach acid may inflame the gut, increasing its permeability to peptides and harmful organisms.
3. Converts peptides into oligo-peptides, on average 5-10 amino acids in length. In those people with leaky guts, this reduces the likelihood of immunological reaction to food antigens, and may also reduce the likelihood of autoimmunity.
