Your stomach acid is necessary for digestion.
The parietal cells of the stomach produce hydrochloric acid, the main constituent of stomach acid. Hydrochloric acid has a very low pH and is extremely effective in breaking down the food we eat. It is particularly vital for:
-The breakdown of protein (it activates the enzyme pepsin for the breakdown of proteins)
-The effective absorption of vitamins and minerals from your food including vitamin B12, iron, calcium and magnesium
-Keeping pathogenic bacteria at bay
-Prompting the release of digestive enzymes and bile from the pancreas and gall bladder respectively.
