Time to digest what you eat depend on individual situations but normally takes between six to eight hours to complete the process without accounting for elimination of undigested food as stools. Once you put your food in your mouth, your mouth produces saliva to help the chemical breakdown and your teeth cut your food into smaller parts so that it can wade through the complex system. After your food goes through esophagus and stomach where your food breakdown further, your pancreas, liver and gallbladder continues to add additional digestive juices for further chemical processing. When your food finally enters small and large intestines, digestive process still continues and all of the nutrients are finally absorbed into your bloodstream from your food and undigested food matter are separated as stools. Keeping this digestive system in tip top shape is vital to the digestive tract and health. Digestive aids that are contained in products such as Coleanse can give an additional boost and help you to maintain your colon at its optimum.
