Should humans eat meat or vegetarian?

We all know that there is a close relationship between physiology and psychology. When we are in poor health, we will be depressed and complain. Similarly, our emotions will also affect our physiological state. For example, when we are depressed, we will eat without scent, and we may not be satisfied with the original food that we are very enthusiastic about. Interested. What's more, some mental illnesses can cause or aggravate some physical diseases. For example, long-term depression can cause various physical conditions such as the digestive system, respiratory system, circulatory system, nervous system and so on.

We often have this kind of experience. Just as we are hungry, we will look for food. Similarly, when we are in a bad mood, we sometimes chews on our mouths, and we can also release negative emotions such as anxiety, that is, eating on us. No matter whether it is physical or psychological, it has such influence.

Having seen a lot of topics on vegetarianism and meat eating before, it led to thinking: Is it more suitable for humans? Or is human being a vegetarian species? If so, will meat and vegetarianism have different effects on people's moods? So, will long-term meat consumption be related to some mental illness, or will vegetarianism be more beneficial to people's mental health?

With such questions and thoughts, I wanted to write today's article called "Humanity is suitable for meat or vegetarian food" in "Vegetarian and Mental Health."

Few people are not concerned about whether their lives are happy and happy. And happiness itself is inseparable from our physical and psychological. In this case, it is necessary to explore diets that are closely related to the body and mind. So what is the human physiological structure? Is it suitable for meat?

Mammals can be roughly divided into carnivorous animals, herbivorous leafy animals, and fruit-eating animals according to their eating habits. In the following, we compare meat animals, herbivorous leafy animals, and fruit-eating animals with humans. From the aspects of human physiological structure, physical functions and digestive system, humans are more suitable for meat or vegetarian diets.

1, meat-eating animals

All carnivores, including lions, dogs, wolves, cats, etc., have a very "short" digestive system. The length of the small intestine of predators is only about three times the length of the body (referring to the trunk, excluding the head and limbs).

This is because meat foods are rotted very quickly. If they stay in the body for too long, the poisons generated after their decay will immerse into the blood stream. Therefore, carnivores have formed a short digestive tract through long-term evolution to facilitate the corruption of meat. The poisons they produce can be rapidly excreted.

In addition, carnivores also contain high concentrations of hydrochloric acid in the stomach to digest fibrous tissue and bones in meat. The strength of hydrochloric acid is about 20 times stronger than that of vegetarian animals.

Most carnivores go out for prey during the cool night, and sleep during the daytime. Therefore, sweat does not need to be sweated through the skin to reduce body temperature. Instead, it radiates heat through the tongue.

Vegetarian animals are different. Animals like cows, horses, and deer, etc., have to feed on the hot sun most of the time from morning to night. Therefore, sweating through the sweat glands of the skin requires a lot of sweat to reduce the body temperature.

The biggest difference between carnivores and vegetarian animals is the difference in teeth.

In order to kill prey, predators need to have sharp claws, strong jaws and long and sharp incisors and canines (in the front of the mouth) to pierce and tear (mainly rely on teeth) tough skin.

Generally, vegetarian animals first chew corn-like foods in the mouth for preliminary digestion before they are sent to the intestines. However, predators do not have flat caries, so meat foods are concentrated foods and do not need to be crushed in advance. The digestion process takes place almost entirely in the gastrointestinal tract.

In the case of cats, it can hardly use teeth to chew food.

2, herbivorous leaf animal

Such animals usually rely on eating herbs, tree leaves or other plants, such as elephants, cattle, sheep, camels and so on. All they eat is rough or heavy food.

Herbivore's saliva usually contains a digestive fluid called salivary starch mash, which is used to digest starchy foods. The digestion process has begun in the mouth.

Those rough foods must first be carefully crushed and thoroughly mixed with saliva starch before they can be sent to the stomach for further decomposition. Therefore, herbivorous leaf animals have 24 flat molars that can be chewed by moving them slightly to the left and right (the teeth of carnivores can only move up and down).

Herbivore animals have no claws and their teeth are not pointed. When they drink water, they suck in their mouths, while in carnivores they use their tongues.

Unlike carnivorous animals, plant foods eaten by herbivore leaves do not decay quickly and can be fully digested and absorbed through the intestines. Therefore, the small intestine is much longer than carnivorous animals and is about 10 times the length of the body. .

It is worth noting that it has recently been discovered that if herbivorous animals change to eat meat, the body will be seriously damaged.

Scientists in the United States have done such a test: If you add half a pound of animal fat to your rabbit's feed every day, two months later, your rabbit's blood vessels will be filled with fatty lump, which presents a serious condition of arteriosclerosis.

The human digestive system is just like rabbits. It is not designed to digest meat. Eating meat will cause people to suffer.

3, fruit and vegetables

Such animals mainly include apes, which are the closest animal ancestors to humans.

Apes are mainly living on fruits and nuts. They have flat molars used to chew foods; their saliva is alkaline and, like herbivorous animals, also contains saliva, starch gills, for the initial digestion of food in the mouth; their intestines twist around, their intestines The length is approximately 12 times the length of the body (trunk) and is suitable for slowly digesting fruits and vegetables.

4, human

The physiological characteristics of human beings are almost the same as those of the fruit-eaters. They are very similar to the herbivore leaf animals and far from the predators. The human digestive system, the structure of teeth, and physical functions are completely different from those of carnivores.

Like apes, the human intestine is approximately 12 times the length of the body (trunk); humans use sweat sweat glands (in tiny pores) on the skin to reduce body temperature; humans use their mouths like all vegetarian animals. The way it sucks is to drink water; the structure of human teeth and cockroaches is designed for vegetarianism; human saliva is alkaline and contains saliva starches for pre-digesting cereals.

Therefore, in terms of physiological structure, human beings are not predators.

Based on the anatomy of the human body and the structure of the digestive system, it can be concluded that during the millions of years of evolution, we have always lived by eating fruits, nuts, grains, and vegetables.

Humans do not have the instinct to eat meat at all. Most of us rely on others to kill animals for us to get meat. If we kill ourselves physically, we will feel sick or uncomfortable.

Carnivorous animals generally eat raw meat, and we humans use boiled, grilled, fried and other methods to be cooked before they are cooked. During the cooking process, we also use various condiments to hide the original taste of meat.

A scientist once said: “A cat that smells fruit is indifferent. If one likes to catch a bird, he can tear his flapping wings with his teeth and suck his warm blood. It can be concluded that nature gives people the instinct to eat meat. On the contrary, a bunch of luscious grapes can make people drool. People do not want to eat fruit when their stomachs are not hungry, because people really think it is delicious.”

The scientist and naturalist Linne (V, Linne) once said: “Comparing the physiological structure inside and outside the human body with other animals, we know that fruits and juicy vegetables are foods that nature has given to humans.”

In short, the scientists' research on physiology, anatomy and animal behavior shows that people are more suitable for eating fruits, vegetables, nuts and grains.

The physiological structure endowed by nature is not suitable for eating meat, and most diseases in the world are caused by eating meat. The vegetarian diet is in accordance with the laws of nature. The vegetarianism is the instinct that nature has endowed to mankind, and it is also the wisdom given by nature. Of course, it is in line with the virtues of heaven and earth.

In fact, we all know the fact that if we only eat meat instead of rice, vegetables, and fruits, we can't overeat it, but we can only eat rice, vegetables, and fruits without eating meat without problems.

Scientists believe that the diet of any animal must be adapted to its physiological structure. Human physiological structure, physical function and digestive system are completely different from those of carnivorous animals. Human physiological structure is not suitable for eating meat.

Therefore, through the above analysis, people who are concerned about happiness and health can think about it. Are we more suitable for meat or vegetarian? (Source: Know the Daily News)
