For the body to use the nutrients in the food you eat, your digestive system must work properly.
Digestion the chemical process of breaking down food and releasing nutrients in a form suitable for use by the body.
You could not digest food if there were not a variety of pH levels within your digestive system.
One of the main digestive juices in the stomach is gastric juice.
It is a strong acid, with a pH of 2 or less.
The amount of gastric juice produced is regulated so the the pH of the stomach remains between 1.5-1.7 .
The enzymes that digest protein need this highly acidic environment.
