Stomach Health is very important. The stomach is an organ located just to the left of the upper abdomen. It plays a crucial role in your everyday life and helps the digestive system. The walls of the stomach physically break down food you have eaten throughout the day. Acid and Enzymes are also released in the stomach to help breakdown food chemically. Thus, the food has now been broken down, so it is now easier for the body to process. For example pepsin is involved in the breakdown of proteins. Having an unhealthy stomach can lead to all sorts of problems.
