How long does it take to digest different foods?
When 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.
Digestion times by food groups:
Water and juices 20-30 minutes.
Fruit, smoothies, soups: 30-45 minutes.
Vegetables: 30-45 minutes.
Beans, grains, starch: 2-3 hours.
Meat, fish, poultry: 3 hours or more.

The digestion process takes between 24 and 72 hours, six to eight hours to pass through your stomach and small intestine. Then the food enters your large intestine (colon) for further digestion and absorption of water. Elimination of undigested food residue usually begins after 24 hours. Complete elimination from the body may take several days."
Think of it as putting ice on a muscle. The muscle stiffens and does not function as well. Warm or room temperature water, juice, or decaf tea will encourage proper digestion.

At first, food travels relatively quickly through your digestive system. Within six to eight hours, the food has moved its way through your stomach, small intestine, and large intestine.
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. A Mayo Clinic study found that the average time food spends in the large intestine varies by gender: 33 hours for men and 47 hours for women.
Your digestion rate is also based on what you’ve eaten. Meat and fish can take as long as two days to fully digest. The proteins and fats they contain are complex molecules that take longer for your body to pull apart.
By contrast, fruits and vegetables, which are high in fiber, move through your system in less than a day. In fact, these high-fiber foods help your digestive track run more efficiently in general.
The quickest to digest are processed, sugary junk foods like candy bars. Your body tears through them in a matter of hours, quickly leaving you hungry again.
Digestion is the process by which your body breaks down food and pulls out the nutrients your body needs to operate. Anything left is a waste product, which your body removes.
Your digestive system is made up of five main parts:
- mouth
- esophagus
- stomach
- small intestine
- large intestine
This is what happens when you digest food:
As you chew, glands in your mouth release saliva. This digestive liquid contains enzymes that break down the starches in your food. The result is a mushy mass called a bolus that’s easier to swallow.
When you swallow, the food moves down your esophagus — the pipe that connects your mouth to your stomach. A muscular gate called the lower esophageal sphincter opens to let the food move into your stomach.
Acids in your stomach break down the food even more. This produces a mushy mixture of gastric juices and partially digested food, called chyme. This mixture moves on to your small intestine.
In your small intestine, your pancreas and liver contribute their own digestive juices to the mix. Pancreatic juices break down carbohydrates, fats, and proteins. Bile from your liver dissolves fat. Vitamins, other nutrients, and water move through the walls of your small intestine into your bloodstream. The undigested part that remains moves on to your large intestine.
The large intestine absorbs any leftover nutrients from the food. The rest becomes solid waste, called stool.
Your rectum stores stool until you’re ready to have a bowel movement.
