Humans in the East and the West have observed the important relationship between food and health. For example, in the Five Dynasties, some outstanding people in our ancestors summed up the motto: Illness comes from the mouth. The police reminded everyone not to eat anything, even food. In ancient times, food was scarce, and even if the food went bad, such as moldy or rancid, it was still reluctant to throw it away. However, eating these spoiled foods may directly lead to death, even if it is not immediately fatal, it will easily lead to various chronic diseases in the long run.

In order to prevent food from spoilage, people developed pickling technology. And handed down from generation to generation. But today, pickling technology has become an outdated technology harmful to health, because a large amount of salt in pickled food will lead to high blood pressure, and nitrite may lead to cancer. In fact, the incidence of digestive system cancer in China is amazing, accounting for nearly half of the top ten common cancers, which has to be said to have a lot to do with traditional unhealthy eating habits. In this environment, for example, the diet of pregnant women is different from peacetime. Pay attention to folic acid supplementation in the first trimester, increase protein intake in the third trimester, and eat more animal protein, such as fish, eggs and meat.

The National Cancer Center released the cancer report of 20 19, and the data in the report are the types and relative proportions of cancer in China in 20 15 years. We can see that among the top ten most common malignant tumors, digestive system-related malignant tumors include gastric cancer, colorectal cancer, liver cancer and esophageal cancer. These cancers are closely related to eating habits, and the incidence rate is quite alarming.

The human body needs to ingest three nutrients and corresponding vitamins and minerals to maintain basic health, which is the basis of the concept of healthy diet. Every year or every few years, according to the latest scientific research, the Ministry of Health will issue a healthy diet recommendation table or a dietary guide for residents, pay attention to the dietary guide, and try to eat according to the recommendations in the healthy diet recommendation table. This is the most important way to keep healthy.
