1. First line of defense against bacteria, parasites, viruses, and yeast.
Stomach acid triggers the release of the pepsin. This is protein digestive enzyme. Bacteria, parasite, virus, and yeast are also made up of proteins. When the pH of the stomach is at its correct level, pepsin will also digest these pathogens. However, if the pH is alkaline, the pathogens will thrive and create issues in the gastrointestinal tract.

If the stomach pH is high, the ascaris worm (parasite) migrates from the small intestine to the stomach. Furthermore, this occurrence causes nausea and vomiting.

2. Promotes digestion and absorption of important nutrients.
Many people are nutrient deficient and low stomach acid is the reason. They are also eating a healthy diet but are unable to digest and absorb the food their eating. If stomach acid is low, the carbohydrates, fats, and proteins are not properly digested and absorb. Stomach contents will not pass through the duodenum if there is no proper acidity level. As a result, food sits in the stomach longer. This also causes bloating, burping, and pain.
