Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.  Best Answer: Alright Joe, fat takes the longest to digest. Sometimes up to 4-6 hours. Proteins are next. I'm talking about proteins from meat and stuff. They take roughtly 3-4 hours to fully digest. NOTE: whey protein is digested in about 20-30 minutes, casein about 7 hours. Veggies will take about 30-45 minutes. Fruits about 20-30 minutes to digest. That's why I always eat fruits first, then veggies, then meat, then the fatty part of the meal if there is any Tweet. Food digestion varies depending upon the type of food. I will break down the process into its steps and provide a timeline for each step. First we see the food. This stimulates our brain to ready our stomach to receive food, by increasing gastric secretions. Then, we eat the food. Amylase is a digestive enzyme in our saliva that helps to break down carbohydrates. Mechanical manipulation by chewing breaks the food into smaller pieces which provide more surface area.  Digestion time varies between individuals and between men and women. After you eat, it takes about six to eight hours for food to pass through your stomach and small intestine. Food then enters your large intestine (colon) for further digestion, absorption of water and, finally, elimination of undigested food. In the 1980s, Mayo Clinic researchers measured digestion time in 21 healthy people. Total transit time, from eating to elimination in stool, averaged 53 hours (although that figure is a little overstated, because the markers used by the researchers passed more slowly through the stomach than actual food). However for clear understanding, digestion time will solely depend on the type of food consumed by an individual. For example fruit and veggies take 30 minutes to digest, liquids take about 20 minutes, carbohydrates take 3 hours and meat takes 24 hours. This is why it is advisable to drink lots of water, eat lots of fruit and veg, but limit your consumption of meat. Food digestion rates also depend on the gut transit. For food to digest it has to go through a number of different processes. In this article I will discuss a little bit about them. Food digestion takes 12-48 hours on average. The average transit time through just the large intestine (colon) was 40 hours, with significant difference between men and women: 33 hours for men, 47 hours for women. Two British doctors studied digestion time in children. In the 1980s, Mayo Clinic researchers measured digestion time in 21 healthy people. Total transit time, from eating to elimination in stool, averaged 53 hours (although that figure is a little overstated, because the markers used by the researchers passed more slowly through the stomach than actual food). Your body can digest most food in less time it takes hotshot celebrities to get engaged: about 4-12 hours. Fruits are the fastest travelers on the intestinal interstate, with meats driving like an oversized load in the right lane (they can take 2-3 days to be excreted or even longer as it rots inside your intestine). A steak dinner can take you two, maybe three days to get out of your intestine. What that means is the way you digest it is basically to rot it in your intestines. On the other hand, if you eat vegetables and fruits, they're out of your system in less than 12 hours.. In the stomach, the food is broken down into easily absorbable ingredients: proteins, sugars and fats. Then greenish brown bile produced in the liver is added to help the breakdown of these fats. By the time the food leaves your stomach and passes into the small intestine, it's unrecognizable. The walls of our intestines absorb the nutrients into our blood and that's how we get the energy we all need to live. A steak dinner can take you two, maybe three days to get out of your intestine. What that means is the way you digest it is basically to rot it in your intestines. On the other hand, if you eat vegetables and fruits, they're out of your system in less than 12 hours..
