The longest food stays in your stomach is 72 hours.
Although most food only stays in your stomach for 40 minutes to 2 hours.
Then after the food leaves the stomach, the food travels through the small intestine and the food then stays in your small intestine for around 2 hours to 6 hours.
The actual time that the food stays in your stomach will depend on the type of food you eat.
Some foods take longer to digest in the stomach than other foods and even drinks can take different amounts of time to leave your stomach.
Foods such as beef and lamb stay in your stomach for 3 hours to 4 hours.
Pork stays in your stomach for up to 4.5 hours to 5 hours.
Chicken that is skinless stays in your stomach for 1.5 hours to 2 hours.
Hard cheese can take over 4 hours to leave your stomach.
Rich raw milk can stay in your stomach for up to 6.5 hours.
Fatty foods and protein and fiber foods take longer to digest and leave your stomach.
Fat is the slowest macronutrient, which requires more time in the small intestine.
Protein and Fiber are dense nutrients which require more work to break down and add bulk, which slows your stomach's emptying process.
High fat foods like fatty cuts of meat, whole milk, full fat cheese and even pizza delay stomach emptying significantly.
Proteins that are dense like chicken, pork, lamb and beef take longer than carbs, and red meat is especially slow to digest in the stomach.
Nuts and seeds like nut butters and almonds are rich in fat and protein, which makes them slow to digest.
And complex carbs and fiber, like whole grains, legumes, beans and lentils and starchy vegetables slow digestion and promote fullness.
