Following the perspective of a fighting expert: James Wilkes, the documentary revolves around the athletes who attach great importance to diet and nutrition, and launches the understanding and discussion of their vegetarian options. The record includes a large number of real cases, nutritional knowledge, Social information and precious real emotions are revealed.
The film is not so much a kind of science and education as it is a kind of exploration. You can be a novice or a judge, but as long as you are willing to understand, you will definitely have a surprise at the end.
People have always had obstacles to understanding vegetarianism. Many doubts have actually appeared repeatedly. We can focus on breaking it down:
1. The vegetarian diet is very small, and may be concentrated in people with religious beliefs or individual reasons. Ordinary people have life and production needs and will not choose vegetarian food at all.
First of all, don’t guess the global vegetarian scale based on the surrounding vegetarian atmosphere. You can check and find out. Then you will find that there are many vegetarian cities, a large number of vegetarian people, a large number of vegetarian restaurants, and a large number of public or private vegetarian cultures in the world. Organizations, etc., these are objective existences, flourishing in areas you don't know.
And if you think those conceptual ordinary people cannot move you, then in the documentary, the author shows many cases of vegetarian elite athletes, including boxers, marathon athletes, sprinters, cyclists, weightlifters, rugby athletes, and vigorously. Project people, etc., constantly enumerate in a vivid way, infecting your understanding of the vegetarian atmosphere. You must know that it is impossible to enumerate any information, so you don't have to think that these are still special cases, that is in vain. The author's starting point is to let you change your inherently closed understanding and understand it with an open and revised mind.
And when you start to discover that there are many high-energy demanders who choose vegetarian food, and the ancient gladiators choose vegetarian food, you don’t have to worry about understanding their reasons and sharing, because you must hardly empathize with those who seem to It will affect your words and make you want to imitate. It is actually unstable, because you still have deep doubts that have not been answered (this will be what we will do next), and at this stage, you It only needs to change the one-sided understanding of the vegetarian group in the past, and it succeeds.
2. Can a vegetarian diet really get enough nutrition?
This is the most common question. Even if many people choose a vegetarian diet, even if they are healthy, it is difficult to dispel people's doubts, so it needs to be thoroughly answered by science. Human survival needs to obtain food from the outside world, and use food to help humans grow and provide energy. The authoritative statement is: humans need to obtain from the outside world: protein, fat, carbohydrates, vitamins, dietary fiber, water and minerals, the most controversial of which is the source of protein.
The first misunderstanding is: we need protein to supplement energy. But energy actually comes from carbohydrates (and stored in muscles in the form of glycogen), not protein. When we focus too much on protein supplementation, it will lead to an imbalance in the intake of protein and carbohydrates. Not only can we not supplement enough new energy due to the lack of carbohydrates, but also lead to existing carbohydrates or The long-term depletion of glycogen, from the perspective of energy, will cause long-term fatigue and loss of endurance. Therefore, the first adjustment is to shift the focus to carbohydrate supplementation. The main food sources of carbohydrates are: sugars, grains (such as rice, wheat, corn, barley, oats, sorghum, etc.), fruits (such as sugar cane, melon, watermelon, banana, grapes, etc.), dried fruits, dried beans, Root vegetables (such as carrots, sweet potatoes, etc.).
The second misunderstanding is: for protein supplements, animal protein is better, while plant protein is inferior and not suitable for humans.
First of all, the proteins ingested by humans, whether animal proteins or plant proteins, are macromolecular substances. Humans cannot directly absorb proteins that are not really needed for the operation of the human body. After these proteins enter the human body, they will be decomposed into amino acids and combined again. Known as the various types of proteins needed by humans. Therefore, amino acids are the value of protein. The reason why humans need to obtain amino acids by ingesting protein from the outside world is that there are 8 kinds of amino acids (lysine, methionine, threonine, leucine, isosine, valine, phenylalanine) that are human Those that cannot be synthesized internally are human essential amino acids.
Secondly, the argument that “plant protein is inferior” is derived from “plant protein is incomplete protein and cannot provide enough essential amino acids for humans.” This theory is actually wrong, because it is scientifically proven that all plants contain essential amino acids for humans. Animals are just a dissemination medium. The difference between the two proteins is the ratio of essential amino acids. Therefore, it is completely possible to obtain complete amino acids or high-quality protein by supplementing plants. Studies have also proved that for humans, as long as the intake of amino acids is appropriate, it does not matter whether they are derived from plants or animals. As for the question of "appropriate intake", as long as you scientifically understand the proportion of amino acids contained in plants, you can easily achieve it. After all, perhaps you have never really understood the amino acid content of animal protein in your intake. (For example: the lysine content of essential amino acids in rice is low, while the lysine content of soybeans is relatively high. If rice and soybeans are mixed, the lysine can supplement each other, which is beneficial to improve the utilization rate of protein.)
Finally, the statement that "the digestibility and absorption rate of vegetable protein is lower than that of animal protein" is true on the whole. Because vegetable protein is surrounded by cellulose, it has poor contact with digestive enzymes, so the digestibility is low. However, plant-based foods are processed and cooked, and the cellulose is destroyed, softened or removed, which can improve the digestibility of plant-based proteins. This requires us to understand the characteristics of plant foods and choose a reasonable way to consume them. After all, we should It is to know what we are eating and how to eat.
At this point, you should have unlocked a key understanding, no longer evasive ignorantly, and then you can understand what the impact of vegetarianism on the human body will be.
3. Does a vegetarian diet make the human body healthier?
With the same nutritional supply, in addition to maintaining normal human growth and activities, "healthier" means "positive and sustainable circulation", which ensures the healthy operation of our body organs during the process of continuous absorption and consumption. It's another topic. What is the relationship between the food we eat and the body?
Let's start with the conclusion: food has a direct relationship with the function of our endothelial cells.
First, what's the use of endothelial cell function? Our body is a sophisticated system. All organs operate in an orderly manner during system regulation. Endothelial cells are the key to regulating the blood flow of the entire system. Their function is to protect each organ by flexibly stretching or contracting blood vessels. Get blood on demand. Studies have shown that animal protein and fat have a negative impact on endothelial cells, resulting in a decrease in their ability to stretch and contract blood vessels, affecting the normal operation of the entire body, and the impact can last up to 6-7 hours. Plant foods can help endothelial cells and improve their functions (there are also many data in the documentary, such as the improvement of athletes’ recovery ability, etc.). This principle can be explained by the fact that plant foods have higher antioxidant capacity than animal foods. It reduces the oxidative pressure of endothelial cells to improve their functions.
In addition to hindering blood flow, animal protein is more likely to cause inflammation in the body (if you understand nutrition, you will know that cardiovascular and cerebrovascular diseases, cancer, arthritis, etc. are actually inflammations that cause human diseases). Animal protein itself contains inflammatory molecules, bacterial endotoxins, heme iron and other undesirable factors. At the same time, when animal food enters our body, it will also change the microbiota in our internal organs, trigger the overgrowth of inflammatory bacteria, and generate inflammatory factors. . Where inflammation occurs, whether it is in the arteries, skin or joints, or even the brain, the human body will get sick. The obtained plants are antioxidants (the antioxidants are 64 times that of animals), and the phytochemicals, minerals, and vitamins provided can alleviate inflammation (experimental data: three weeks of vegetarian food, the body’s The degree of inflammation can be relieved by 29%), make full use of the microbiota to ensure the healthy operation of all aspects of the body.
There are many guidelines on how humans eat healthier and prevent diseases. Readers can understand the causes of diseases and slowly understand that it is an indisputable fact that a vegetarian diet will make the human body healthier.
4. Why has society been advocating animal food for many years? Is the public wrong?
There are two aspects here: "What we do see" and "What society allows us to see."
"We can indeed see it": The establishment of human knowledge requires a process, and this process requires the investment of human, material and financial resources. The truth about vegetarianism is also revealed little by little: limited archaeological evidence, let us discover it after a long time Human ancestors were also vegetarians; at the same time, the physiological structure of human beings was originally made for vegetarianism...and in this process, academic research, social cognition, and commercial promotion related to "human beings are suitable for animal food" spread rapidly, leading to the truth His voice and behavior were buried.
"Society allows us to see": It is a masterpiece of commercial games, including advertisements in newspapers on the screen, a dazzling array of products in shopping malls... The influence of commerce spreads to agriculture, animal husbandry, medical care, academics and even the government, and business is staged in society. No one promises whether the drama is the truth or not. Just imagine that cigarettes are still on sale? The argument on whether cigarettes are related to cancer is still circling endlessly. It is the people who are going to suffer, and who will be the beneficiaries?
Truth is in the hands of a few people. In this era of information explosion, this rule has not changed.
5. How does a vegetarian diet make individuals healthy, and what does it have to do with protecting the environment?
Human demand for animal food drives a huge social production scale, which occupies a lot of land and oceans, severely disrupts the natural ecological balance, causes immeasurable pollution, and even leads to the extinction of a large number of animal and plant species from the earth.
Because we need animal food, we need to raise animals through animal husbandry, and in order to raise them well, we need agriculture to grow grains and draw water to feed them. When you thank the uncle farmers for their hard work to create food for you, the animals give more thanks, because 83% of the world's agricultural land is made for them. When you thank the water conservancy workers for their hard work to provide you with sufficient drinking water, the animals also give more thanks, because for their needs, 25% of the world's rivers no longer enter the ocean.
We have called for the love of forests since we were young, but 70 billion animals need to be raised every year in the world. For this reason, a forest the size of a football field is torn down every day. Animal husbandry has long been the main cause of deforestation, but humans are unable to talk about it. Only after feasting on animal food, opening a platform application and planting a small tree far away.
And let's look at our input-output ratio for animals? Animals consume six times the protein they produce. A burger, from production to transportation to us, we need to pay 2,400 liters of water. Thank them for the output of the "essence" they have brought us, and the animals have left us with a bigger mess, which is the pollution of the environment: the huge amount of animal excrement leads to the pollution of rivers, lakes, and groundwater. Animals The gas produced by them accounts for 15% of the global man-made gas emissions. It can be said that while the whole people are working hard to travel green, perhaps the effort of a mother cow's hiccup is offset.
6. Vegetarian food protects humans, but what does it mean to animals?
This is actually a heavy topic, but also a humane topic. With the increase in demand, the destruction of the environment has caused wild animals to lose their homes and are on the verge of extinction; for the animals that are being raised, they are experiencing a mustard-like life. When the primitive animal husbandry has been transformed into an industrialized production model, the factory The animals are suffering unimaginable suffering. (The specific content will not be expanded in this article for the time being)
The ranger's words in the documentary were very moving: "I can't protect animals during the day, but I am eating meat when I come back at night. The easiest way to protect animals is not to treat them as food."
At the end of the documentary, there is a kind enlightenment from vegetarians: "When people decide to do something, they often feel that it is unsuccessful, but they are not." "Don't tell him, you have to be a vegetarian, but say,'Why not try Try to eat less meat for a week?’” So, maybe it’s far away, but the way to start is just under your feet.
Just like the big project person said: "The point is not to become the strongest and most burly person, what is important is what you use your power to do, and how to make good use of your power!"
