How long does it take to digest different foods?
If you know how much time it takes for a food to digest in your stomach it is much easier to plan or make adjustments to your diet. The gastric-discharge depends on the quantity of the food, its characteristics, its chemical composition, the pH of the stomach, the peristalsis intensity. For example, the liquid goes almost immediately into the small intestine, carbohydrate-rich foods quickly, rich in protein and fat-rich foods are the slowest.
Stomach muscles push, twist, and interfere the food with the gastric juice, and its walls are almost constantly moving. In normal digestion, they are working stronger in every 3 to 3.5 hours. The stomach can hold about 1.5 to 3.5 liters of food. From the stomach the food moves forward and goes into the small intestine. And so ends the digestion and absorption begins.
