Reflecting on it, I feel that the viewpoint of the film is too extreme. The science component is less than the brainwashing component. Junk food, refined food, high fat, high calorie must be punished, but is it really necessary to overdo it and become a vegetarian? So Zhihu asked some questions:
1. Documentary: The secret under the knife and fork (a fork is better than a scalpel), is it science? This documentary seems to have used a lot of scientific experiments to support its views, but how does it feel so one-sided? Many issues have not been clearly stated. Meat eating (omnivorous to be precise) must be unhealthy?
Eating grass must be healthy? 2. In terms of diet, is animal diet or overnutrition or other reasons leading to the high incidence of cancer, heart disease and diabetes?
3. I like sports and fitness. For the time being, I don’t ask whether vegetarianism is good for gaining muscle. I only ask whether vegetarianism can keep people who need a lot of protein healthy?
4 Vegetarianism may also cause obesity due to excessive calorie intake. Doesn't it cause diseases such as cancer or diabetes?
