So what's more in vegetarianism: good or harm? The only thing that can be said for sure is that orthodox vegetarianism, or old vegetarianism, is not suitable for long-term nutrition. This system can sometimes be used for a short time. Long-term use of the strictly vegetarian way of eating is considered unacceptable, because over the years vegans develop a severe deficiency of iron, zinc, calcium, vitamins B2 and B12, B, and the essential acids lysine and threonine. There are many examples of this, and the story of the Lykov family, who have lived in the taiga for more than fifty years, is very indicative. They wrote a lot about them in the Soviet era, so I will not retell it, I will only indicate that the surviving son and daughter of the Old Believers had all of these deviations and were extremely exhausted because they ate only plant food.
Even healthy people, who have excluded all animal products from their diet, can go as far as dysbiosis, vitamin deficiencies and protein deficiency. While patients suffering from serious illnesses, including malignant tumors, diseases of the lymphatic and circulatory systems can pay with their lives.
As for the young, or ovolaktoevarians, any healthy person can use the experience of their nutrition, because with milk and eggs, he will still receive most of the valuable nutrients. But if a person decided to switch to vegetarianism in order to get rid of some disease, it would be right to think carefully or consult a doctor first, as in some diseases of the gastrointestinal tract, the abundance of plant food can worsen the condition of the digestive organs. However, it should be noted that the vegetable food helps to fight constipation effectively.

The transition to a vegetarian diet is primarily recommended for patients suffering from metabolic disorders, manifested by obesity, gout and atherosclerosis. Vegetarianism in these diseases is a kind of therapeutic nutrition.
Introduction to eating cereal products, vegetables and fruits, berries and herbs is useful not only for vegetarians. Most people have enjoyed this for centuries, observing occasionally fasting, because fasting provides for the exclusion of animal products from food. The main difference of fasting from vegetarianism is that the period of restrictions alternates with normal nutrition. From a scientific point of view, the post is even more beneficial to the body, as for. a relatively short period of fasting (several weeks) in the body can not develop a shortage of essential nutrients.
During the post creates a great opportunity to expand the range of fruits, vegetables, herbs, roots, mushrooms and berries in their daily menu. During this period, the body "rests" from fatty foods, smoked meat, meat, salted fish, etc. And it is very good that at present the irrevocable departure of militant atheism into the past has allowed most of us to return to Orthodox rituals and traditional Christian posts.
Finishing the conversation about vegetarianism, I want to remind once again that the transition to vegetable nutrition is not recommended in childhood and adolescence (during the intensive growth of an organism that has not yet become strong). You should not resort to vegetarianism during pregnancy and lactation, as well as in extreme old age. Well, as for all the others, they are free in their choice.
