Where the fat accumulates first after absorption

The specific process is divided into three parts: digestion, absorption, and metabolism.

1. Digestion of fats.

Since fats are insoluble in water, and enzymatic reactions in the body take place in aqueous solutions, fats must be emulsified before they can be digested. Bile salts from the gallbladder play an important role in fat digestion.

It first purifies the fat and reduces its surface tension, and then emulsifies the fat into very fine emulsified particles. Pancreatic juice contains lipase, which is broken down by lipase.

2. Absorption and re-esterification of fats.

The absorption process of fat digestion products is not well understood. When fatty acids and monoglycerides, the digestive products of fats, are released from the micromass, they can re-esterify monoglycerides in the cells of the small intestinal mucosa.

3. Intermediate metabolism of fats.

When fats are digested, the resulting glycerol, fatty acids, and monoglycerides enter intermediate metabolic processes. Among them, monoglycerides and some fatty acids are not transported, that is, they are re-esterified in the cells of the small intestinal mucosa to form fat.

The glycerol and fatty acid components that are absorbed and transported are metabolized in the liver, adipose tissue, and muscles.

Fat absorption: Fat is digested by bile salts, pancreatic juice, intestinal juice and lipase to form glycerol, free fatty acids and monoglycerides, a small amount of diglycerides and undigested triglycerides.

Bile salts play an important role in the digestion and absorption of fats, and they can form water-soluble complexes with the hydrolysates of fats. These composite parasol compounds are further polymerized into adipomicrons, which are only 4-6nm in diameter and mainly contain three components: bile salts, glycerol qihumonoester and fatty acids. It is thought that this fat microparticle can be absorbed by intestinal epithelial cells.

Direct absorption by swallowing. It has also been suggested that when these fat particles are absorbed, the main components are still separated into the epithelial cells of the small intestine, and then resynthesized into neutral fats.

And on the outer bread a layer of lecithin.

and protein membranes, which become chylomicrons. There are two ways in which fat is absorbed. First, chylomicrons and most long-chain fatty acids enter the chyle duct and indirectly enter the blood through the lymphatic pathway; Second, short and medium-sized fatty acids and glycerol containing less than 12 carbon atoms are soluble in water, which are absorbed by capillaries and directly enter the blood circulation.

Since the fat in food is mostly long-chain fatty acids, the absorption of fat is mainly based on the lymphatic pathway.

1. Abdomen.

Belly fat causes the body to produce too many inflammatory proteins that flow to the bloodstream, liver, muscles, and brain, which is harmful to health.

2. Heart. It can easily cause high blood pressure, high cholesterol, insulin resistance, sleep apnea, increase the risk of heart attack, and even death.

3. Liver. If there is a fat accumulation around the liver, it will not only affect the liver function, but also produce insulin resistance and increase the risk of diabetes.

4. Intestines. Intestinal microbes are involved in maintaining normal metabolic function, and fat accumulation in the gut can disrupt the normal microbial balance and lead to problems such as insulin resistance.

5. Lungs. Studies have shown that small sacs or vesicles produced by fat or other cells can travel to the lungs and other organs, delivering harmful substances and triggering asthma or other diseases.

6. Brain. Excess fat can also accumulate around the brain and affect brain function. Studies have confirmed that patients who undergo ** surgery do have improved cognitive function.

7. Subcutaneous. New research by Professor Steven Smith and colleagues at the Sanford-Burnham Institute for Medical Research has found that fat located below the surface (especially the subcutaneous fat of the thighs and calves) can absorb energy and actively store energy, thereby playing a role in protecting the liver.

A: 1High content of visceral fat.

2.High subcutaneous fat.

Two different areas of fat have different health effects.

High visceral fat, easy to suffer from high blood pressure, high blood lipids, high blood sugar and other diseases, this kind of pot-bellied "** obesity" is the biggest killer of health. High fat in internal organs is caused by unhealthy dietary composition.

People with high subcutaneous fat have a bulky body, decreased energy, and poor body shape. High subcutaneous fat is caused by a slow metabolism or a high-calorie diet.

There is no absolute distinction between high visceral fat and high subcutaneous fat, it is often that the visceral fat storage is high, and the subcutaneous fat storage is also high!

It can be seen that there is more fat, which not only affects your image, but also affects your quality of life.

Body fat is mainly distributed in the subcutaneous tissues, around the internal organs, and on the omentum of the abdomen. The subcutaneous tissue is the largest storage site for fat in the body. Normally, about 2 to 3 percent of the fat in the body is stored in the subcutaneous tissue.

The amount of fat stored in the subcutaneous tissue of different parts of the body is not exactly the same, and the thickness of the subcutaneous fat layer in different parts of the body can also be different in the same obese person. The abdomen, buttocks, and bilateral upper thighs, as well as the lower back, have a greater capacity to store fat than the rest of the body. In women, the back of the shoulders and the inner and outer sides of the upper arms are also places where fat is easily deposited.
