Old myth: Food is bad, some are better! Legend is a legend, after all, as long as seriously to verify, and then magical legend has shown the truth ~~~~~

Since ancient times, the theory of TRADITIONAL Chinese medicine has had a profound influence on the people, as evidenced by the widespread spread of the theory of food compatibility among the people. It is said that, in fact, the theory of food compatibility is a little lack of scientific basis (it is rumored that the Chinese Nutrition Society has done animal experiments and human trial eating research. The conclusion, according to legend, is that both animals and humans have been tested and no adverse reactions have occurred. Take a look at some common folk food against the actual situation:

1. Soy milk and eggs

The mucinous protein in eggs combines with the trypsin in soy milk to produce a substance that cannot be absorbed by the body.

Comments soybean does exist trypsin inhibitors, it not only affects the digestion and absorption of protein, but also may appear abdominal distension, abdominal pain, diarrhea and other symptoms. However, trypsin inhibitors are poor in heat resistance and can be destroyed if heated long enough.

2. Persimmon and crab

Eating persimmon and crab together can cause poisoning. Because the astringency of persimmon comes from tannins, which precipitate the crab's protein, which clumps when eaten together, making it difficult for the body to digest.

If the tannins in persimmon precipitate the protein in crab, then the tannins in fish, meat, eggs and milk cak as well. So persimmon and fish, meat, eggs, milk may also be incompatible.

3. Fruit and seafood

Phase grams of reason in the seafood is rich in protein and calcium nutrients, such as if and contains more tannic acid of fruit, like grapes, hawthorn, pomegranate equivalent, not only can reduce the nutritional value of protein, and easy to make seafood of calcium combined with tannic acid as a material difficult to digest, cause upset stomach, abdominal pain, vomiting and nausea. Vitamin C rich in fruit is enol structural substance with strong reducibility. The arsenic contained in seafood, especially shrimp meat, is pentavalent arsenic, which will be reduced to trivalent arsenic when encountered with vitamin C. Pentavalent arsenic is non-toxic, while trivalent arsenic is highly toxic. So don't eat shrimp with fruits or vegetables that are rich in vitamin C.

Review the REDOX reaction of vitamin C in reducing arsenic pentavalent to arsenic trivalent can be carried out under normal chemical reaction conditions, but whether this REDOX reaction is carried out in gastrointestinal tract has not been determined.

Beef and chestnuts

Beef and chestnut mixed together to eat, prone to indigestion, vomiting and other symptoms.

Comment on beef and chestnut eating together is not only incompatible, but also the effect of health. Chestnuts are nuts that are high in starch and are not as oily and indigestible as nuts such as walnuts, hazelnuts and almonds. At the same time, chestnut is also rich in dietary fiber, high nutritional value. In autumn and winter, chestnut is stewed with beef. It is very suitable for people with weak spleen and stomach function, while healthy people can eat it to strengthen their body. However, when eating, we must control the amount, such as eating beef every time not more than 2 two, six or seven chestnuts can be.

5. Soybean and pork

Soybean has a high phytic acid content, of which 60%~80% of phosphorus is phytic acid. It often forms complex with protein and mineral elements, which affects their availability and reduces utilization efficiency. Polyphenols are one of the anti-nutritional factors of beans. They interact with protein, affecting protein solubility and reducing its utilization rate. Polyphenols can also act with proteolytic enzymes and amylases to affect digestion and thus the absorption of protein in beans themselves and meat.

Legume cellulose in the aldoxylic acid residues can be combined with lean meat, fish minerals such as calcium, iron, zinc and other chelates, interference or reduce the absorption of these elements. Soy contains flatulence factors, which the body cannot digest. These factors in the intestinal tract due to the role of bacteria, after the decomposition of a large number of gas, coupled with indigestion and other factors, easy to appear abdominal distension, constipation. Therefore, pork stewed soybean is a taboo food collocation.

This is not true. Soybeans are not the only foods that contain phytic acid. It is also found in flour and rice. From the point of view of nutrition, the farther the protein species, the higher the nutritional value after collocation, pork and soybean collocation just conforms to this principle. As for the problem of abdominal distension caused by eating soy beans stewed with pork, it may also be caused by eating soy beans alone, so it is impossible to judge whether the abdominal distension caused in this case is caused by improper collocation of the two or caused by soy itself.

Eat meat and drink tea

A large number of tannic acid and protein in xiangke reason tea combined to generate tannic acid protein with convergence, so that the intestinal peristalsis slowed down, the water in the stool reduced, thus prolonging the retention time of feces in the intestinal tract. Drinking tea while eating meat not only causes constipation, but also increases the possibility of toxic and carcinogenic substances being absorbed by the body.

There is some truth in the comment, but the actual impact is minimal. With fewer tannins in tea leaves, even less can be extracted from the tea, and their effect is negligible compared to the amount of protein a person consumes each day. Herdsmen in pastoral areas of Tibet and Inner Mongolia often drink butter tea and milk tea, but they do not have indigestion, constipation and other symptoms. Those who need to remind is, gastrointestinal digestive function is weaker, can drink tea again in 1~2 hours after the meal.

7. Milk and juice

Popular reasons for opposing each other:

Milk and fruit juice mixed together to drink, the protein in milk and fruit juice acid and vitamin C meet and coagulate into blocks, affecting digestion and absorption, but also make people appear abdominal distension, abdominal pain, diarrhea and other symptoms.

review

It is normal for proteins in milk to be precipitated by acid. Gastric acid is much more acidic than orange juice, if acid precipitation is not absorbed, milk is not the hope of absorption?

There is a difference between the protein in any food and the protein your body needs. This difference affects the body's bioavailability of proteins contained in food. Mix the protein of different source edible, conduce to produce protein complementary effect, make protein utilization rate gets rise, reduced protein thereby to be decomposed, metabolize, also reduced the generation that contains nitrogen material, reduce kidney burden, very beneficial to the body.

Pumpkin and lamb

The same food is difficult to digest. According to compendium of Materia Medica, "Pumpkin should not be eaten with mutton, which causes qi blocking." The reason is that pumpkin can fill qi, mutton hot tonic deficiency, two tonic with, will lead to chest tightness, abdominal distension and other symptoms.

Modern nutritionists believe that pumpkin and mutton is a good match. Mutton is high in protein and rich in minerals and vitamins. Pumpkin nutritional value is very high, especially carotene, sugar content is higher, protein and fat content is lower, often eat can effectively prevent hypertension, diabetes and liver disease, improve human immunity.
