First of all, the absorption and utilization rate of raw meat nutrition is not high. Some friends feel wrong when they see this factor. They may say, "Isn't heating cooking going to lose some nutrients?" According to this truth, it should be better to eat raw, right? "It is true that some nutrients will inevitably be destroyed during the heating process, but as long as it is not over-cooking for a long time and ultra-high temperature, the loss is actually worth it.
The absorption of protein by our human body is a process of "destruction", so protein in meat is denatured after heating, and it is easier to hydrolyze into amino acids, so natural digestion and absorption are better, while protein absorption in raw meat is much more difficult.
The part of raw meat that is difficult to absorb and utilize is far greater than the part lost in cooking, so although the nutrition of meat is lost a little in cooking, the absorption and utilization rate of cooked meat is much higher than that of raw meat, and the part that is difficult to absorb and utilize when eating raw meat is far greater than that lost in cooking, which is one of the main reasons why we humans don't need to eat raw meat.
Now even children will know that raw meat contains more harmful microorganisms such as bacteria, and eating raw meat is more likely to be infected with parasites. After proper high temperature heating, all unfavorable factors such as bacteria, viruses and parasites on fresh raw meat can be basically killed.
At first, it was just a way of baking, and gradually there was a way of cooking and steaming. Cookware also changed from hot stones to clay pots, kettles, retort and so on. It can be said that the development of human civilization in a certain period is also the development of cooked meat cooking.
Raw meat is not chewy, it tastes too hard. Raw meat is not chewy, it tastes too hard. If the meat is not cooked, the meridians of the meat will be closely connected, and it will not be chewed if it is chewed in the mouth for a long time. If you really eat raw meat as a meal, you may not be full for three or four hours. This kind of life is spent eating meat, our work is delayed and our life will be affected. Fourth, raw meat is too bloody and disgusting.
We humans are thinking higher animals, and we will have our own judgments about things. What is better? Of course, it is normal to have a choice. Cooked meat is more nutritious, tastes better and is more convenient to eat than raw meat.
Safe, hygienic, nutritious and delicious Now that human society is progressing, human beings just have higher requirements for food: safe, hygienic, nutritious and delicious. Some foods can be eaten raw, such as sashimi and oysters. However, some foods, such as snails, must be cooked at high temperature to remove bacteria from the food itself, which makes them more delicious and safer to eat. There are also some foods that are not bacteria, but will be more nutritious and delicious after cooking at high temperature, such as rice.
We humans are a group of advanced animals, standing at the top of the action chain. We pursue better, more delicious and healthier food, and most foods have to be cooked at high temperature to meet our needs, so we see that most of them eat cooked food.
