The large intestine absorbs any remaining water and leftover nutrients from the food. The undigested part that remains moves on to your large intestine.
Vitamins, other nutrients, and water move through the walls of your small intestine into your bloodstream. Bile from your gallbladder dissolves fat. Pancreatic juices break down carbohydrates, fats, and proteins. In your small intestine, your pancreas and liver contribute their own digestive juices to the mix. This mixture moves on to your small intestine. This produces a mushy mixture of gastric juices and partially digested food, called chyme. A muscular gate called the lower esophageal sphincter opens to let the food move into your stomach.Īcids in your stomach break down the food even more. When you swallow, the food moves down your esophagus - the pipe that connects your mouth to your stomach. The result is a mushy mass called a bolus that’s easier to swallow. This digestive liquid contains enzymes that break down the starches in your food. This is what happens when you digest food:Īs you chew, glands in your mouth release saliva.

Meat and fish can take as long as 2 days to fully digest. Your digestion rate is also based on what you’ve eaten. The normal range for transit time includes the following: gastric emptying (2 to 5 hours), small bowel transit (2 to 6 hours), colonic transit (10 to 59 hours), and whole gut transit (10 to 73 hours). Once in your large intestine, the partially digested contents of your meal can sit for more than a day while it’s broken down even more. Within 6 to 8 hours, the food has moved its way through your stomach, small intestine, and large intestine. The rate is also based on factors like your gender, metabolism, and whether you have any digestive issues that could slow down or speed up the process.Īt first, food travels relatively quickly through your digestive system. The exact time depends on the amount and types of foods you’ve eaten. While a salad on its own will digest quickly, the high water and fiber content of lettuce and vegetables helps you feel full.In general, food takes 24 to 72 hours to move through your digestive tract. When they are broken down, the shorter pieces jostle around in the chyme with everything else.Ī salad: 1 hour If you add an oil-based dressing or a protein like cheese or chicken, digestion will take longer. The stomach enzyme pepsin begins to digest proteins by breaking the long protein chains into shorter pieces. The enzymes produced by the stomach begin to break down the protein in the bacon, lettuce, and tomato. Keeping this in consideration, how is lettuce digested?
