In 1983, when we went to the United States, the domestic food supply was tight, and many areas only issued 1-2 pounds of egg tickets a year. To the United States to see eggs, chicken thighs everywhere, that is the cheapest food, all of a sudden we can not turn the corner. Generally meat is not expensive, but most vegetables are not cheap, just so everyone will open foreign meat. However, after one or two months, those who had a strong meat diet reacted with a bitter taste in their mouths, heat in their bodies, redness of their tongues, and severe constipation in some cases. A doctoral student from Sichuan said, “We didn’t have such a big reaction even if we ate spicy food all day long! He said that his greatest happiness now is to have a diarrhea. You guys see, what a drop in the Chinese price! At first, people thought they were not adapted, but practice proved that this can not be adapted, so many people began to pay attention to meat and vegetables, a balanced diet. When I saw that it was fine for foreigners to eat so much fish and meat every day, but not for us Chinese to eat so little, I asked why. I heard some explanations, but I didn’t find any of them reasonable. Once I read an article about carnivores and herbivores in a magazine, which was very inspiring. Then I read some related research articles and realized why Chinese people cannot eat more meat. It is summarized below, let’s see if it makes sense. Researchers point out that carnivores eat meat food nutrient-rich, and easy to rot, so like tigers, lions, wolves like carnivores intestines and short and straight, without many crepe folds. Meat is concentrated food, because enough nutrition does not require a very long intestine to slowly digest and absorb, intestinal short and can be due to meat decay and produce toxins excreted as soon as possible; and vegetarian cattle, sheep, rabbits, etc., vegetarian food in the vegetable proteins and animal and human proteins have a big difference, fiber and a lot of difficult to absorb, so responsible for ingesting food nutrients in the intestines must be longer in order to absorb enough nutrients. The study found that the rabbit length of 0.4 meters, intestinal length of 8 meters, intestines are 20 times the length of the body; goats for 22 times. The tiger, on the other hand, has a length of 1.3 meters and an intestine of only 5.4 meters, which is four times longer than its body length; the wolf is only 3.5 times longer. The relative length of the intestines of herbivores is many times longer than that of carnivores. It seems that this is the difference in survival conditions and the type of food eaten which produces the difference in the length of the intestines. For thousands of years, due to the different natural environments and living conditions in which Eastern and Western people live, they have decided to have very different lifestyles, especially eating habits. The length of intestines of human beings, like that of animals, also varies greatly. Through statistical data analysis found that the meat-based Westerners, the height of about 1.8 meters of the body, the length of its intestines is about 5.4 meters, intestinal length multiplier of 3; and vegetarian-based Asians, the height of about 1.7 meters, the length of its intestines about 8.5 meters, intestinal length multiplier of 5, the gap is indeed very large. We Chinese if we change to eat meat-based, then we have that longer than Westerners so long intestines will be fully absorbed meat in the nutrients, so that our human body is over-nutrition, and can not be like the Westerners as meat in the body to rot the toxins produced as soon as possible excretion, so that the inevitable result is to affect the health of the body. Therefore, we can not blindly go to the fashion of eating Western food, and can not easily listen to the so-called scientific theories of Western nutritionists, we should control themselves, educate the children, do not forget that we are the Chinese race, do not easily change the eating habits of the Chinese people, or we will be severely punished. A recent report released by the American Cancer Society said that more and more people in developing countries today are imitating Western lifestyles, such as the increasing proportion of saturated fats and high-calorie substances in their diets ……, which increases the risk of cancer. In addition, studies have shown that dietary habits and the length of the intestines also determine the differences in temperament between humans and animals. As we all know, carnivores hunt for food that will run and jump, because the next time in the hunt for animals must be instant excitement, energy and physical strength, can not carry out too much thinking and rational analysis, to have the spirit of adventure, and to means of cruelty; and for herbivores, the plant will not run away, you can have time to carefully observe the surrounding environment, analyze whether it is safe, and therefore developed a panic, think twice before you act! Habits. Therefore, among mammals, grass-feeding animals, such as cows, sheep, rabbits, etc., always appear to be gentle and kind, while meat-feeding tigers, lions, wolves, their temperament is almost always ferocious and violent. This difference in character, arising from the difference in the nature of the food, is the same with mankind. Peoples with long intestines are generally gentle and supple, quiet and sensible, conservative and moderate in character, while those with short intestines are rugged, outwardly flamboyant, irritable, combative, aggressive, poorly restrained, and prone to extremes, and so on. The above conclusion is not only the result of observation and statistics but also has scientific basis. Research has shown that the intestines to digest and absorb animal protein, will secrete a hormone called “norepinephrine”. If you eat mainly meat, you will secrete more of this hormone. This hormone increases blood pressure and heart rate, making the cerebral cortex less able to control emotions and more easily agitated. In the long run this has resulted in a meat-based Westerners are easily excited, passionate, adventurous, dare to innovate, love to go out and like to dominate the nature of everything; and vegetarian food contains a lot of cellulose and lignin, the surface of these substances do not look like what nutrients, but in the intestinal tract can be adsorbed in the body of the decomposition of metabolism of harmful hormones, so that they are discharged from the body as soon as possible. In addition, vegetables in the “green juice”, its chemical structure is similar to hemoglobin, long-term diet of this “green juice”, not only can lower blood pressure, but also to make people mentally comfortable, so long-term vegetarian-oriented Oriental people, but also subconsciously shaped out of the mild, quiet and Reasonable nature, thus forming a whole and emphasize the harmony of the Oriental culture, created the “unity of man and nature” system of man and nature. Of course, a small intestine is not the only factor that determines the health and character of human beings, but if we get a little inspiration from it, it will be of great benefit to the Chinese people.
