scurvy!

It can be said that it is not famous.

This is a disease caused by vitamin C deficiency, so it is also called vitamin C deficiency. However, vitamin C deficiency can not only cause scurvy, but also related to inflammation, arteriosclerosis, tumors and other diseases.

It has been a disease that seriously threatened human health in history.

In the past hundreds of years, it has been widely popular among sailors, explorers and the army, especially among long-distance sailors, so it is called "the fear of sailors" and "the evil god of the sea".

The clearer description of scurvy in ancient books is in the records of the Crusades in the Middle Ages.

Some scholars trace back to the time of Hippocrates BC, and it is also said that traces of scurvy were also found on the remains of humans in primitive society.

At the end of the fifteenth century, scurvy was also the reason why many navigators stayed in bed for a long time. Until 1753, James Lind, a Scottish naval doctor, discovered that the disease was related to diet, and found that drinking orange juice and lemon juice could treat and prevent scurvy. Blood disease, so far only the prevention and treatment of scurvy.

This disease is actually very easy to prevent, as long as you often eat vegetables and fruits, you don’t even need to supplement it deliberately.

But if left untreated, it can lead to iron deficiency, ranging from anemia to skin bleeding, loose teeth, personality changes, and eventually death.

"So, scurvy is a disease that only voyage crews who eat only meat and no vegetables will get. But there is another phenomenon that has puzzled scientists in modern times."

"That's why the Inuit who also only eat meat and don't eat vegetables don't have scurvy?"

Gifted?

Or is there another way?

The curiosity of the audience was aroused, and many water friends could not help but sit up straight and listen to Bi Fang's explanation.

Bi Fang cut open another salmon, removed its belly, stuffed it into his mouth contentedly, tasted it deliciously, then swallowed it, and finally sat cross-legged on the ground, and began to explain the reason leisurely.

"As I said just now, low temperature can also kill parasites, and it only needs to be minus 20 degrees. In fact, this is just the normal temperature in the Arctic. Although the relative temperature in the water is much higher, it is not liked by parasites, but this Of course it’s not absolute, low temperature killing insects is far less efficient than high temperature, but it can greatly reduce the chance of being recruited.”

"Moreover, most of the parasites that can survive in the Arctic are harmless to the human body. In addition, the Arctic is almost pollution-free. The combination of the three, even freshwater fish, can be eaten raw, so there is no need to panic."

"As for why it is necessary, in fact, eating raw meat can also supplement vitamin C, eh!"

Bi Fang hiccupped. He hadn't eaten meat for a long time, and he ate too much all of a sudden.

Patting his chest and taking another sip of water, Bi Fang said slowly, "From 1906 to 1918, Vihjalmur Stefansson, an anthropologist and explorer at Harvard University, uh, was Vihjalmur."

For the convenience of everyone's memory, Bi Fang translated Icelandic into English.

"Vihjalmur has visited Canada's small northern region three times, where he spent the winter with the local Inuit, ate and lived together.

"Due to geographical restrictions, the Inuit can only eat meat and animal fat most of the time, such as birds, reindeer, seals, walruses, whales, etc. These foods provide them with all the food for at least 10 months a year. Nutritious, and in summer, they are likely to eat some plant-based foods, such as berries, roots and so on."

"However, like the Inuit, Vihjalmur did not suffer from scurvy from such a diet that lacked fresh fruits and vegetables."

"He got a lot of fire from some skeptics when he made his findings public."

【Hiss, I would doubt it too】

[It doesn't look like a genetic problem]

【Raw meat can also supplement vitamin C? 】

Bi Fang took a sip of warm water, chewed another piece of raw meat, and continued.

"In order to verify again and delve deeper into the principles behind it, in 1928, Vihjar Moore and his colleagues were admitted to Bellevue Hospital in New York, and under the strict control of the hospital and the supervisory team, they started a 'diet diet'. Experiment', that is, like the Inuit, eat meat and animal fat all year round, this insistence is 1 year."

"Before the trial started, many experts predicted that Vihjar Mull would eventually suffer from scurvy due to lack of vitamin C. The result... is naturally surprising."

After the experiment, Vihjarmur is still healthy, and his physical condition has improved to varying degrees, such as quicker thinking, more stable blood pressure, not to mention scurvy, and he has no symptoms of vitamin deficiency. "

Vitamin C deficiency can cause scurvy

Scurvy was first discovered in 1536 by the French explorer Jacob of Brittany, when it plagued those exploring the St. Lawrence River.

Jacob also gave a detailed description of scurvy, and even looking at it now, he can vaguely feel a little horror.

"Some lost all their strength and couldn't stand up Others also found purple scars on their skin and then they started appearing on their ankles, knees, thighs, shoulders etc, their mouths stink and their gums gradually rotted away, The flesh on the body began to fall off, even the roots of the teeth, almost all fell off."

There is no doubt that humans cannot do without vitamin C, otherwise the consequences will be very serious. Moreover, the human body cannot synthesize vitamin C by itself. Unlike cats and dogs, these animals can synthesize vitamin C by themselves.

"About 60 million years ago, the ancestors of humans, the great apes, lost an enzyme needed to synthesize vitamin C from glucose. The name is very long, called gulonolactone oxidase, and finally lost the production of vitamin C. Ability."

"Darwin's evolutionism is undoubtedly correct, but it does not mean that there are no problems, and it can even be said that the problems are very serious."

"The state of human beings at this time is actually not necessarily the most adaptable to the environment. There is a considerable part of the luck factor, so some non-fatal flaws will also exist. Of course, this expansion is complicated, so I will briefly mention it. , I won’t go into details.”

Bi Fang shook the kettle, returned to the topic, and directly explained the reason.

"The end result is actually very simple. A high-sugar diet requires more vitamin C. As long as you don't eat staple foods, your body's vitamin C requirements will drop significantly."

"And there is actually vitamin C in meat. The most important thing is that the vitamin C content in raw meat is much higher than that in cooked meat. This is because part of the vitamin C will be oxidized and lost during the heating process."

"The custom of the Inuit is to like to eat raw meat. I said it when I was in Mohe, and because of this, I got a slightly contemptuous title, called Eskimos."

"By increasing income and reducing expenditure, scurvy will stay away from me."

Bi Fang took a bite of the fish and chewed it.

Finally had a full meal.

Scientists have discovered that more than 80% of body fat leaves the body through exhalation, making the lungs our main organ for weight loss. Human blood contains fats called triglycerides, which are composed of three atoms: carbon, hydrogen, and oxygen. The release of excess fat requires the unlocking of atoms in the triglyceride molecule through a process called oxidation. By tracing the path of every atom in the body, a team of scientists from the University of New South Wales in Australia discovered that when 10kg of fat is oxidized, 8.4kg of fat leaves the body through the lungs as carbon dioxide.
