I have many vegetarian friends around me, almost all of whom are vegetarians, and they don't intend to eat meat any more. Including the elderly and children. My friend has made children vegetarian since childhood. The baby is already a vegetarian in the mother's belly, and even some of the ones it runs in the family are vegetarians. They have never heard of malnutrition. Don't listen to alarmist talk.
Laozi, Confucius, Mencius, Leonardo da Vinci, Mahatma Gandhi of India and many other celebrities are vegetarians. The most outstanding figures in modern times are Jackie Lui and Roy Cheung. Many people don't know that they are vegetarians, and their bodies are much better than those of many meat eaters who are full of fat! Jacky Cheung and Jet Li are vegetarians, so is Toby Vincent Maguire, who plays Spider-Man. When filming, people hang wire all day. Have you ever heard of any problems caused by vegetarianism? For women, Jolin Tsai, Faye Wong and Rene Liu are all famous vegetarians, and vegetarianism is one of the secrets for Jolin Tsai to keep her skin moist and bright.
If you eat a balanced diet, you will be healthy. Vegetarians, on the other hand, have less food choices, so naturally they should pay more attention to food choices. Aren't all meat eaters like this? )
As for the statement that "animal protein cannot be obtained from vegetables and fruits", it is simply an unnecessary answer, indicating that "animal protein" cannot be obtained from plants. However, the absence of animal protein does not mean malnutrition. Plant protein can replace animal protein, such as soybean, and provide protein and amino acids needed by human body. Many bodybuilders do not encourage drinking milk but recommend drinking soybean milk, because plant protein is easily absorbed by human body, while animal protein (even egg and milk protein) is not easily decomposed and absorbed, not to mention meat, which is almost impossible to absorb. So from a scientific point of view, plant protein is far superior to animal protein, and the human body does not need animal protein at all.
Therefore, vegetarianism can lead to malnutrition and loose skin, which is not scientific at all.
This idea is the idea of people who stayed decades ago and thought that vegetarianism was just for eating pickles and tofu, right? I suggest you do more research and learn more about modern vegetarian food (especially organic vegetarian food) before you come to a conclusion.
Although some people only choose vegetarianism for a short time, and then return to vegetarianism for personal reasons, people who no longer choose vegetarianism still account for a large proportion, so lifelong vegetarianism is definitely not a problem.
