Digestion is the process of breaking down nutrients so that they can pass from the intestinal tract into the body. Bacteria in the intestinal tract assist in the process of digesting food and protecting us from foreign invaders. But this bacterial colony can be damaged or destroyed through various factors, such as use of antibiotics, stress, or consuming foods detrimental to them.
Heartburn and acid reflux are very common today, and acid-stopping drugs (antacids) are typically prescribed to reduce stomach acid. But stomach acid is necessary for proper digestion. Reducing stomach acid may reduce heartburn but at the cost of causing malnourishment and diseases that spring therefrom.
Many digestive issues are caused by food intolerances or allergies, and these issues can be reversed through dietary and lifestyle changes.
This section discusses some of the diseases that occur in the digestive tract and how to reverse them, some foods and drugs that commonly cause this damage, and how to build up and maintain proper gut bacteria.
