Why is fried food not easy to digest?

Fried food is crispy and tasty, but it is not easy to digest, and eating too much at once, or eating too quickly, can adversely affect the stomach. We know that the digestion and absorption of food goes through a very complex process. In the mouth, the teeth are responsible for chewing and grinding, and the tongue stirs the ground food evenly.

Saliva contains amylase, which turns starch into maltose, and pepsin in the stomach to break down proteins. The small intestine is the "chemical processing plant" of food, where a wide variety of digestive enzymes are used, and raw proteins, starches and fats are processed.

Fried food is not easy to chew very finely and stir very evenly because of its hard texture, so it can affect its digestion in the stomach and small intestine.

After the food is fried, most of the particles are encapsulated in fat, which reduces the chance of contact with proteases or starches, so these fried proteins and starches are more difficult to digest.

Scientists have done experiments to prove that the amount of gastric juice secreted is related to the nature of the food eaten. When eating bread, gastric juice is secreted the fastest and the most, and the digestion is also the strongest; When eating fatty foods, gastric juice secretion is the least and slowest and digestion is weaker. People don't feel hungry after eating fatty meat, because fatty foods are the most difficult to digest and stay in the stomach for too long.

Because the fried food is covered with a layer of oil, it will affect the secretion of gastric juice, so it is more difficult to digest.

Since ancient times, Chinese medicine has believed that it is not advisable to eat too much, and often eat crispy and fatty foods. Gan, that is, sugar and sweetened sweets; Crispy, that is, frying, frying, burning, smoking and other foods; Fat people are fatty foods; Thick is a large amount of meat.

Not long ago, Dr. Takashi Sugi, director of the National Cancer Center Research Institute of Japan, pointed out in a lecture at the Japanese Society for Cancer Cure that eating too much fried food can easily cause cancer. He found that amino acids, proteins, and sugars all produce mutagenic substances when they are in high heat, and these substances, after ingestion, have the effect of promoting cell cancer.

Through experiments, it was found that the electric furnace was heated at different temperatures such as 100 degrees Celsius, 200 degrees, 250 degrees, 300 degrees and 400 degrees Celsius, and then the amount of mutogenic substances produced by the food at these different temperatures was analyzed. He found that at temperatures below 200 degrees Celsius, the vast majority of foods do not produce mutagenic substances, and at 250 degrees Celsius, only a few fish such as dried squid and dried rays produce mutagenic substances. At temperatures above 300 degrees Celsius, most foods produce a large amount of mutogens except tofu.

Anyone who has studied physics knows that at room temperature and pressure, no matter how fierce the fire is, the temperature of boiling water is 100 degrees Celsius, but during the fierce fire, the water evaporates faster. Therefore, steamed and boiled food will not exceed 100 degrees Celsius in any case, so food cooked by these methods will never produce carcinogenic mutagenic substances.

However, the boiling point of oil is about 250 degrees, so when the food is fried in a pan, the temperature can rise to 250 degrees if it is fried for a little longer. When frying food in oil, the temperature of the food close to the side of the pan can exceed 250 degrees Celsius and reach 400 degrees. The same goes for burnt and smoked food.

Smoked food is even more stained with smoke, which is a carcinogen.

Frying makes the food lose a certain amount of moisture and increase the oil content; Although the frying temperature is high, the internal temperature of the food generally does not exceed 100, so the frying does not destroy much of the nutrients of the food, and the nutritional value will not change greatly. However, there are many varieties of fried food, and the scale of production is different, and the problem will mostly appear in whether the production process is reasonable and standardized, and whether consumers eat it scientifically and reasonably. Studies have shown that some chemicals formed by the decomposition and polymerization of some substances when frying food may have toxic effects on the human body.

For example, cyclic monomers, dimers and multimers produced by frying oil can cause paralysis in the human body, produce tumors, and cause cancer. In general, when the heating temperature of frying is not high and the time is short, this safety problem is not big, but the heating temperature is too high, and the frying oil is used repeatedly, which may produce polycyclic aromatic harmful substances. In recent years, it has also been found that high levels of acrylamide are produced in high-temperature fried foods (e.g. in French fries).

Fried food is harder and not easy to chew finely. In addition, after the food has been fried, it is coated with a layer of fat, which is difficult to dissolve in the stomach and intestines. So, fried food is not easy to digest.

Fried food is not easy to digest, firstly, because the starch or protein in it is severely denatured, and the denatured structure of such nutrients makes it difficult for the human body to digest and absorb; Second, fried foods contain high fat, and high-fat foods are not only difficult to be decomposed by gastric acid in the stomach, but also difficult to absorb nutrients in the small intestine. This is the basic principle of "why fried food is not easy to digest".

After eating fried oil, the stomach will be uncomfortable.

Fried food is crispy and delicious, delicious and colorful, can be eaten at any time after being made into a snack, and it is also very convenient to preserve, so it has always been popular. However, some people think that fried food is not easy to digest, and if you eat it often, you will get stomach problems, and you dare not eat it if you want to; Others believe that this food is crispy and crispy, and has a good color and flavor, which can stimulate the appetite and secrete more digestive juices, which is good for digestion and absorption, so they eat a lot of it.

Is fried food easy to digest? Can I eat more?

We believe that fried food is less digestible, but it is not the most difficult to digest; You can eat some of it, but you shouldn't eat too much, especially if you eat too fast.

The digestion and absorption of food is a very complex process of processing and processing – in the mouth, the tooth tube chews and grinds, and the tongue stirs the ground food evenly. There is amylase in saliva, which turns starch into maltose, and pepsin in the stomach, which mainly breaks down protein into amino acids. The duodenum is the largest "chemist's factory" for food, where a wide variety of digestive enzymes are available, and raw proteins, starches, and fats are processed.

Because of its hard texture, fried food is not easy to chew very finely and stir very evenly, which will affect its digestion in the stomach and duodenal segments.

After the food is fried, most of the particles are encapsulated in fat, which reduces the chance of contact with protease or amylase, so these fried proteins and starches are more difficult to digest.

Scientists have done experiments to prove that the amount of gastric juice secretion is related to the properties of the food grip substrate eaten. When eating bread, gastric juice is secreted the fastest and most, and digestion is also stronger. People don't feel hungry after eating fatty meat, because fatty foods are the least digestible and stay in the stomach the longest.

Because fried food is covered with a layer of oil, it will affect the secretion of gastric juice, so it is also more difficult to digest.

However, although fried food is more indigestible than starch and protein, it does not affect gastric juice secretion like pure fat food. As long as you chew carefully when eating, and don't eat too much each time, digestion will not be very difficult.

Because of the hard texture of the fried food chain, it is not easy to chew very finely and stir very evenly, so it will affect its digestion in the stomach and small intestine.

In addition, after the food is fried, most of the particles are encapsulated in fat, which reduces the chance of contact with proteases or starches, so the protein and starch of these fried suns are more difficult to digest.

It is mainly because of your own spleen deficiency, spleen deficiency is easy to cause food indigestion, resulting in abdominal distention, it is recommended that you can take some spleen and stomach medicine, for indigestion, regulate spleen function.

Hard, it will change a lot after frying at high temperatures...
