There are various reasons to follow veganism.

Some vegetarians do so for health reasons, some for religious reasons, and some for ethical, animal protection and environmental reasons. Some are because of their profession, such as nuns or monks. Others are because they want to pretend to be thirteen and engage in alternatives, and they want to be unconventional and make themselves unique.

In other aspects, some strict vegetarians not only do not eat meat, but even animal-derived products*, such as: bezoar, tiger bone, bear bile, ivory, mink oil, musk, fish oil, chicken essence, ejiao, etc.; They are also not engaged in occupations related to killing, such as slaughtering, non-vegetarian catering, aquaculture, fishing, etc.

Xia Yu's vegetarian diet is not selective, and he doesn't eat any meat-related food, not even eggs and dishes cooked in lard.

Seeing that Xia Yu didn't eat meat, Gu Feng's heart suddenly moved, was her illness related to her not eating meat?

Thinking of this, Gu Feng couldn't care about anything else, he couldn't take care of eating, and Xia Yu didn't care, so he hurriedly went back to the room to flip through the book.

After turning over all the miscellaneous medical books on the shelves, I finally found a record about vegetarianism!

Long-term vegetarianism, because the vegetarian diet is low in calories and severely deficient in protein and fat, can cause malnutrition.

According to a study conducted by a medical university on monks and nuns in some monasteries, most nuns and monks were malnourished to varying degrees.

Children born to long-term vegetarian women often have one or another kind of developmental disorder.

Protein is the main raw material for building and repairing human cells and tissues, and long-term deficiency has a great impact on the body's ability to resist diseases.

Not eating meat for a long time can also cause trace element and vitamin deficiencies. Essential trace elements such as zinc, calcium, iron, etc. mainly come from food. Zinc is mainly derived from animal foods, with 80% of dietary calcium coming from milk and 80% of iron coming from meat and eggs. Vegetarian food contains less zinc, calcium, and iron, and contains more phytic acid and oxalic acid, which will hinder the attraction of trace elements such as zinc, calcium, and iron.

For example, the oxalic acid contained in spinach can combine with the calcium in tofu to become calcium oxalate, which is not absorbed by the human body. Therefore, long-term vegetarians are prone to some diseases caused by lack of trace elements: zinc deficiency can cause anorexia in children, pica and decreased sexual function and infertility in adults; Calcium deficiency can cause rickets in children and osteoporosis and osteoporosis in middle-aged and elderly people; Iron deficiency can cause anemia and affect the mental development of children.

Not eating meat for a long time can also cause fat deficiency. Fat has a high caloric production, and unsaturated fatty acids are the "food of the human brain", which is extremely important for promoting the intellectual development of the brain, so long-term vegetarian diet is more harmful to adolescents with rapid growth and development. Girls who are often vegetarian tend to have their menstrual periods delayed!

After Gu Feng learned that Xia Yu was a vegetarian, her observation was no longer limited to her, but her sister Xia Bing was also included in the scope of observation.

Originally, Xia Yu, who had no problems, was compared with her sister Xia Bing, which seemed to be a problem.

First of all, Xia Yu and Xia Bing are twin sisters, but Xia Bing doesn't care about chickens, ducks, fish, cows, pigs, dogs, sheep, geese, etc., except for human flesh, she has been eating other meat since she was thirteen and a half years old, and Xia Yu, who has not eaten meat since she was a child, only came to menarche at the age of seventeen.

Secondly, another point is that Xia Bing, who eats meat, has been lively and active since he was a child, mixing with boys like a wild boy, he has not been sick or painful since he was a child, and he has not even had a cold, but Xia Yu, who does not eat meat, has been quiet and introverted since he was a child, and he is frail and sickly, either a cold or a fever, and he has to be carried to the hospital by Xia Shenghai in three days. It wasn't until I grew up and my body became more resistant that there was no pain.

Also, these twin sisters, on the surface, although there is no difference at all, in fact, there is a difference when they take off their clothes, Xia Bing's figure is a little plumper than Xia Yu, of course, this little difference cannot be seen under the cover of clothes, especially the two sisters like to wear exactly the same clothes.

However, this difference is naturally not something that Gu Daguan is fortunate enough to witness, although he is very blessed, but he did not watch the blessing of a pair of delicate twin sisters bathing together at the same time, but Su Man'er came back to describe it after going to the hot spring with them to do a sauna, and he said that he had a nose and eyes, and even Xia Yu's navel had a small mole, but Xia Bing's did not, and the sparse contrast of hair, etc., were all clearly stated.

Hearing this, Gu Feng was first happy, with this difference, wouldn't it be very simple to distinguish which one is Xia Bing and which one is Xia Yu in the future? Then I couldn't help but sigh in frustration, doesn't this difference mean that there is no same? He can't just lift their clothes every time he sees these two sisters!

Xia Yu is willing, Xia Bing is also refusing!

However, no matter how big the real difference between the two sisters is, Gu Feng believes that the cause of Xia Yu has been found.

Xia Yu died suddenly because of heart problems caused by vitamin deficiencies caused by not eating meat.

Nowadays, there are many heart diseases caused by vitamin A, vitamin D, vitamin E, vitamin B1, and vitamin B6 deficiency, some of which are directly caused and some are indirect.

When he happily called Yan Xinyue to tell him about this conclusion, Yan Xinyue actually had some gains, but her gains were not just guessed like Gu Feng, but there was real evidence.

She believes that Xia Yu has a disease called "Brugda syndrome", which is a very rare condition, and there are not many cases in the world!

The disease was discovered in 1986 by a professor of cardiology in Poland, but it was not included in clinical textbooks because there were so few cases.

The cause of this disease is not a problem with the blood supply of the heart, but an abnormality in the heart electrical current hidden behind it, caused by ventricular tissue tremor, and its symptoms are also like Xia Yu, coma without any reason, unawakened, shock, cardiac arrest, and some even die quietly in their sleep at night.

This disease must be tested by an electrocardiogram (ECG). Because although "Brugda syndrome" is asymptomatic and occurs in seemingly healthy people, it has a very typical ECG finding, that is, the shark ray.

Whether it is a disease or not, as long as you have an electrocardiogram (ECG) monitoring!

After the two finished talking on the phone, Yan Xinyue immediately came to Gu Feng's house with a portable ECG, and then performed an ECG examination on Xia Yu.

The results of the examination came out, but they were still the same as the electrocardiogram results of the municipal people's doctor, and there was no abnormality.

When Gu Feng was wondering, Yan Xinyue took out a reagent, she said that the shark ray pattern of this special "Brugda Syndrome" was very cunning, sometimes hidden, and it had to be revealed by injecting a special reagent.

Gu Feng couldn't help but scoff when he heard this, he didn't approve of this disease originally, but now that he had made such a reagent like a demon mirror, he didn't believe it even more.

Yan Xinyue insisted on her opinion, injected reagents into Xia Yu, and then performed an electrocardiogram examination, and when the results came out, she really saw the difference between it and a normal electrocardiogram, and an obvious shark ray pattern appeared.

After Gu Feng read the results, he thought that it was due to the influence of the drug, and he was not sure.

In order to make him die, Yan Xinyue injected Xia Bing with reagents, and then did an electrocardiogram examination, but the result was that there was no abnormality, let alone a shark shark pattern, and even the shark's mouth could not be seen.

After this test, Xia Yu's illness can almost be said to be clear. She is suffering from "Brugda syndrome"!

After finishing, Yan Xinyue took out the complete literature and materials she had sorted out to show Gu Feng.

After Gu Feng looked at it carefully, he couldn't help but point out all kinds of suspicions, the cases in the literature are basically hereditary, but as far as Gu Feng knows, Xia Yu has no such genetic history in his family. Moreover, most of those cases came from Western countries, and they were not mentioned in China.

Therefore, a student and a teacher had a heated argument about Xia Yu's illness, and in the end, the two had a jaw-dropping quarrel.

Yan Xinyue firmly believes that Xia Yu is because of the "Brugda syndrome" to appear sudden death, only to do ICD (buried cardioverter defibrillator), is a match-sized instrument, can be buried under the skin of the chest, there is a wire connected to the heart, once the heart has ventricular fibrillation, the defibrillator can immediately identify and send out a safe current, painless stimulation of the heart, eliminate ventricular fibrillation, so as to restore normal heartbeat, this is the only way to effectively prevent "Brugda syndrome". The difficulty of this operation is not great, even if it is the current Gu Feng, it can be done.

However, Gu Feng believes that Xia Yu may be "Brugda syndrome!" But even if it is this disease, it is because of the vitamin deficiency caused by her not eating meat that causes the ventricular tissue to tremble and appear "Brugda syndrome", as long as she can correct this vice and get sufficient nutrition, she and Ben do not need to install any defibrillator, because her ventricular tissue will no longer tremble, and the disease will be cured without medicine.

The two of them have seen each other, this woman said that the mother-in-law is reasonable, and the public says that the public is reasonable, and the people present are not professionals in this area, so they can't even persuade them, and in the end they can only watch the two quarrel and break up unhappily.
