Eat vegetarian from a nutrition perspective

DoctorVu Huong Van

Once upon a time, many scientists believed that a vegetarian diet was not provided with all kinds of nutrients, would be weakened .

Now, vegetarianism is becoming a popular trend in European and American countries, it is recommended to use a variety of plant-based foods. However, from a nutritional perspective, many nutritionists recommend absolute vegetarians to consciously choose food so that the body can provide the best quality.

In the world, there are currently 4 types of vegetarian (with author divided into 6 types) are vegetarian with milk, vegetarian using eggs, vegetarian with milk and eggs, absolutely vegetarian. But there are also those who claim that there are only two types of absolute vegetarianism and relative vegetarianism (using milk and eggs; or only vegetarian for a few days, some other days, eating fish and chicken). Vegetarian food is absolutely out of plant food, so do not use any foods of animal origin.

Humans are not carnivorous

Vegetarian schools (vegetarians) all have common views, although the degree varies slightly, but are unanimous: people are not carnivores, but eat cereals and vegetables, so vegetarian is not eating meat. Researchers have provided evidence to prove that humans are cereal eaters:

Comparing claws of fangs to find carnivorous beasts with sharp claws like knives is to pounce and tear off prey. The unique up and down movement of the jaw, sharp sharpness of long fangs and lack of teeth for grinding. The intestine is very short (only 3 times the length of the body), the stomach is more acidic (10 times more than non-carnivorous animals), because the digestion of meat requires no stagnant long food in the intestine, does not cause rotten fermentation to produce many toxins.

Humans are organisms that eat cereals, vegetables, and other digestive structures that are different from carnivores. Human teeth are for grinding grains, very long intestines (6 times the length of the body) passing food takes 18-24 hours. In fact, primitive human beings who are absolutely vegetarian, have not yet found fire to cook, must eat raw, slower digestible food requires more time in the long intestine to be fermented. lactic. Until later on knowing how to use fire, they knew how to eat meat. If you eat cereals and vegetables, there is only lactic fermentation, almost no stench and no toxins. When glucid-rich plant foods are easy to ferment, fermentation occurs early and prevents it from rotting, which usually occurs more slowly. Lactic acid fermentation bacteria work in acidic environment, and fermenting bacteria do not develop in this environment. Rotting fermentation produces many toxic substances.

Under the lens of medicine, vegetarianism helps prevent many diseases.

Anti-meat arguments

It is said that as with all sciences, nutritional physiology originates from the West, where large cattle breeding develops very soon. At the same time, the wool industry, the meat and dairy industry . also thrive. Western nutritional physiological science was born on that basis, so they took meat as the main research object, of course, there could be no other way of looking at animal protein. Based on the concept of biological value proposed by Osborne in 1909, Western studies were conducted on white mice - the most easy-to-breed experimental animal. Mice differ from humans, mouse growth in weight and body weight increased 112 times faster than people. Thanks to this, researchers are able to see that animal protein is the best. Indeed, a generation of people who eat a lot of meat is bigger than a father who eats less meat, but is that development good for the whole life? Or as rice fertilizer nitrogen fertilizer, ' fast ' , high trees, dense leaves, but poured young, poor seeds.
Vegetarian food comes from plants.

Through the price of eating too much meat, right now in the West, there is a 'renewed' view. Eating meat to a certain extent in the intestine occurs a rotting process, because the long intestine stays down for a long time, in the stool contains toxins. An American doctor analyzed urine from carnivores and vegetarians and found that compared with the kidneys of the fasting kidneys of carnivores, it was 3 times harder to eliminate the complex toxins in the meat. . When people are young, they can often tolerate this abnormal burden to the point where there is no sign of injury or illness occurring. But when the kidneys get old and become weary slowly quickly, they will not fully function and disease is an obvious result.

Another study found that eating a lot of meat when digesting the body produces homocysteine, which makes the vascular wall vulnerable, enabling cholesterol to form arteriosclerosis. It has been found that higher levels of homocysteine ​​are more susceptible to coronary artery disease that causes myocardial infarction and carotid stenosis, which can easily cause cerebral anemia, or stroke.

In addition, an animal when the extreme pain of life is killed, is also worth noting. Because the biochemistry of an animal is terrified by horror, it goes through profound changes when it struggles desperately to live and produces poison. The toxins excreted from pain . are pushed throughout the body, in the blood and completely absorbed into the animal's tissues. According to the Brittanica Encyclopedia, its toxins include uric acid and some other toxins.

Is vegetarian enough nutrients?

Once upon a time, many scientists believed that a vegetarian diet that was not provided with enough nutrients would be weakened. But there is an obvious fact that true monks eat only foods of plant origin and remain healthy, with many people reaching a long life. The current trend, many people believe that vegetarian health is not inferior to eating meat, sometimes even healthier. The scientist Albert Einstein said: 'There is nothing to benefit human health and increase the chances of survival in this world by developing a vegetarian diet'.

Under the lens of medicine, vegetarianism helps prevent many diseases. The vegetarian diet is low in cholesterol, low in saturated fatty acids, and polyunsaturated fatty acids. There are many flavonoids and carotenoids, many vitamins E, C are effective against free radicals arising in the body. Therefore, vegetarianism prevents many diseases such as obesity, cardiovascular disease, type 2 diabetes, gallstones, cancer, dementia . In addition, vegetarianism tends to be less prone to inflammation. appendicitis, less prone to irritable colon syndrome, hemorrhoids and varicose veins .

However, nutritionists recommend absolute vegetarians to be conscious of choosing food so that the body is fully supplied. Vegetarians are more prone to energy deficiency because of their low fat and fiber content, which means those who are in need of increasing energy demand (growing children, pregnant or nursing women .) It should be noted that eating enough calories is necessary, such as eating lots of oilseeds, eating extra snacks, drinking plenty of soy milk. Cereals are often lacking some essential amino acids such as lysine (rice, corn, wheat), threonin (rice), tryptophan (corn) and methionine (legumes). Therefore, a good vegetarian diet is to eat a mixture of plant foods so that they supplement the essential amino acids for each other.

Minerals also play a very important role. Often in vegetables provide insufficient calcium, iron and zinc. Therefore vegetarians should use a lot of fruit juice, products from beans. When cooking, avoid too much salt to eat vegetables - because sodium interferes with the body's absorption of calcium. Do not eat green fruits, or acrid because tannin reduces iron and zinc absorption. Eat iron-rich foods such as legumes, dark green leafy vegetables and dried fruits. Eat brown rice, whole wheat is a lot of zinc.
