Fashion about vegetarianism came to Europe in the middle of the XIX century. Albert Einstein, Ilya Repin, Henry Ford and many others counted among the followers of this current. Among the living now, meat is not eaten by Mohammed Ali, Nikolai Drozdov, Richard Gere, Madonna, etc. However, the debate about whether vegitirism is useful or harmful does not abate so far. A person is a predator or a herbivore? The talk about the benefits of vegetarianism or potential harm will begin with a discussion of how people are adapted to the meat ration.
The person has large sharp incisors, undeveloped fangs and flat root that connects us with herbivores. However, our teeth are covered with enamel from all sides and change with the course of life only once, which prevents us from chewing coarse vegetable food for a long time and is more like the teeth of predators. Such teeth have omnivores.
In predators, salivary glands are poorly developed, saliva is acidic and does not contain enzymes. Herbivorous saliva is alkaline and includes enzymes that digest starch.
In predators, it is small, the gastric juice is very acidic, the main digestion occurs right here. In herbivorous, the stomach is large, multi-chambered, gastric juice is slightly acidic, since in the stomach there is not digestion, but fermentation of food. A man has a medium-sized stomach, gastric juice is weaker than that of predators, but much more acid than that of herbivores.
Undigested meat in the intestines undergoes bacterial decomposition with the release of toxic waste, so predators need a short bowel to quickly evacuate leftovers. On the contrary, the herbivores need a long intestine, which exceeds the growth by 20-28 times, as vegetable food is digested very slowly. In humans, the intestine exceeds growth by 8 times and is able to easily digest both light vegetable food (mostly fruits) and small portions of meat.
The conclusion from the above is the following: A person can not digest a large amount of coarse plant food, for example, grass, as is not able to eat only meat. Evolution has made us omnivorous, a person can be a vegetarian, but meat in the diet is necessary for normal growth of the body and maintaining health.
Arguments – AGAINST VEGETARIANITY
The influence of vegetarianism on life expectancy is only theoretical. It is assumed that vegetarians are less prone to cardiovascular disease, therefore, they live longer. Some northern peoples generally eat only meat and live long enough. The vegetarian diet is poor in some vitamins and trace elements, found only in meat – primarily B12 and iron. Fans of plant food in 70% of cases suffer from anemia and iron deficiency, as well as related problems – fragility of nails and hair loss, poor working capacity, problems in the work of the intestines, violation of the menstrual cycle in women, etc.
In plant foods, there are not enough calcium, iodine, vitamin D. From this, may occur be problems with the bones, teeth and thyroid gland, which is extremely dangerous, especially in old age.
Vegetarianism is harmful to pregnant and lactating women who are not able to get enough protein from plant foods. Vegetarianism is inadmissible for children under 15 years of age. If you don’t feed your baby with meat from time to time, then it is inevitable that it will suffer from dystrophy, anemia, dysplasia and mental retardation. Children under 15 years can not be vegetarians, and the opinion of scientists on this issue is very categorical. Most of the problems described are not related to vegetarianism as such, but to its radical direction – veganism.
