Even though fat has gotten a bad rap over the years, it’s actually essential to your health.
Fat supports several of your body’s functions and gives your body the energy that it needs. Fat also helps your body absorb important vitamins and gives your body essential fatty acids that control inflammation, improve brain health, and more.
The amount of time that fat takes to digest varies from person to person and between men and women.
In the 1980s, Mayo Clinic researchers found that the average transit time from eating to elimination of stool was approximately 40 hours. Total transit time averaged at 33 hours in men and 47 hours in women.
Once fat is broken down during digestion, some of it gets used right away for energy, and the rest is stored. When your body needs extra energy, such as when you exercise or don’t eat enough, it’ll break down the stored fat for energy.
Fat takes longer to digest than other foods, and the amount of time varies based on the type of fat. Dietary fats consist of:
+ Saturated fat
+ Trans fat
+ Monounsaturated fatty acids
+ Polyunsaturated fatty acids, including omega-3 fatty acids
+ Trans and saturated fats are considered unhealthy fats and raise LDL cholesterol.
How is fat digested? The vast majority of fat digestion and absorption occurs in the where?
The digestion of fat mostly occurs in the small intestine, but it can sometimes begin in mouth where lingual lipase breaks down some lipids. Before absorption, fats have to be emulsified (broken down to small droplets) and it is done thanks to pancreatic lipase from the pancreas and bile from the liver. Monoglycerides and fatty acids associate and form micelles (together with bile salts and phospholipids, vitamins and cholesterol). Micelles are necessary for the transport to the enterocyte, but only freely dissolved monoglycerides and fatty acids can be absorbed.
The process of fat digestion involves a series of steps that begin the moment food enters your mouth. Here’s a look at the process from beginning to end:
The digestion process begins when you start chewing your food.
Your teeth break the food into smaller pieces, and your saliva moistens the food so that it’s easier for it to move through your esophagus and into your stomach. Your saliva also contains enzymes that begin breaking down the fat in your food.
When you swallow, a series of muscle contractions called peristalsis moves the food through your esophagus and into your stomach.
Your stomach lining produces acids and enzymes that break down your food further so that the foods can pass to the small intestine.
4. Small intestine
The majority of fat digestion happens once it reaches the small intestine. This is also where the majority of nutrients are absorbed.
Your pancreas produces enzymes that break down fats, carbohydrates, and proteins.
Your liver produces bile that helps you digest fats and certain vitamins. This bile is stored in the gallbladder. These digestive juices are delivered to your small intestine through ducts where it all works together to complete the fat breakdown.
During this process, fat and cholesterol are packaged into tiny particles called chylomicrons.
Can you improve the fat digestion process?
Nutritional supplements. Supplements containing digestive enzymes have become more and more popular, although more research needs to be done on how effective they are. However, it’s been shown that they may provide promising results for more than just enzyme deficiencies.
These supplements may contain many different enzymes that help break down specific foods.
A study in 2013Trusted Source showed that papain may help digestion and relieve symptoms such as bloating and constipation in people with irritable bowel syndrome (IBS).
As mentioned, more research is still needed to further investigate supplements for fat digestion. Always talk to your doctor before taking a supplement meant to improve fat digestion.
