I said it wasn't groundless. In this colorful society, vegetarians are a clean stream. If vegetarians only need many nutrients that vegetarians can't provide, such as calcium, iron, zinc, selenium, vitamin D, protein and so on. Similarly, if vegetarians don't eat these for a long time, they will easily lose their mental state, lose their luster and lose weight.
In fact, it is not good to do anything too extreme. Many vegetarians hardly eat shredded meat, some of which I can understand, because they really can't eat meat, because they adhere to the principle of "vegetarianism is king". But most people don't eat vegetarian food simply to lose weight and keep their weight and figure. The effect of doing so may achieve the purpose of losing weight, but it is not good for your health. It is likely that there are many problems in the body after losing weight. Isn't this throwing watermelons and picking up sesame seeds?
Although vegetarians can ensure that their vitamins are supplemented, eating more fruits and vegetables is also easy to digest, which is indeed an environmentally friendly and healthy lifestyle. But in the long run, a diversified and reasonable diet is more conducive to the protection and prevention of the body, mind and blood vessels.
To sum up: I think the healthy diet structure of modern people should be based on plant food, supplemented by meat food, so that the human body can effectively absorb human necessities and maintain the most effective health. It is unrealistic to achieve a healthy diet by vegan regimen. Although "vegetarian food" is very popular now, and "vegetarian restaurants" have almost opened all over the streets, the healthiest way to keep fit in life should be a reasonable diet with vegetarian dishes.
