In many foreign countries, people like to eat salads, steaks and other foods. They seldom touch cooking, unless one day they want to eat Chinese food on a whim. But even if they don't eat stir-fry, they will supplement protein, vitamins and trace elements every day. Raw vegetables are actually healthier than stir-frying, and the nutrients are preserved more completely.
Actually, cooking still has some disadvantages, because the oil temperature is too high when cooking, which is easy to produce carcinogens. Moreover, if the cooking temperature is not well grasped or the cooking is limited, the fried dishes may be burnt, and at the same time, a lot of oil smoke will be produced, which is very unhealthy for the body. So from this point of view, we can't say that not eating fried dishes is harmful to health. Eating stir-fried dishes may also be harmful to health.
So in fact, we can't generalize, but we still have to divide the situation. We can't say that all cooking is healthy, nor can we say that not eating cooking will definitely endanger health. This is very unreasonable. Eating stir-fried dishes or stews is just a personal eating habit. As long as you feel satisfied and you are more used to cooking, you can choose to eat more cooking.
However, if western countries prefer to eat fast food, they don't have to force themselves to eat stir-fried dishes. After all, vegetables and fruits are eaten raw directly, which is much more nutritious than cooking. China people are not used to eating raw food, while westerners are not used to eating stir-fried food. These are all formed in long-term living habits, so we should not use specific cooking methods to determine our health, so this statement is definitely incorrect.
