Domestic food shortages require early grain storage
With the rapid spread of the New Coronary Pneumonia epidemic worldwide, some countries have begun to restrict or ban food exports, causing international food prices to rise. In the context of the global food situation, a news that "China's food supply is facing a crisis" circulated online, and many people began to hoard food. So is there really a crisis in China's food supply?
In this regard, Wei Baigang, director of the Development Planning Department of the Ministry of Agriculture and Rural Affairs, said that China ’s grain production is abundant and its stocks are sufficient. Even when the domestic epidemic was serious in the previous stage, the grains and various types of non-staple foods on the market were stable at sufficient prices. The people at home are all worried about rice noodles, and there is no need to buy and hoard now. Food still needs to be eaten new.
Wei Baigang shared 4 sets of data to eliminate people's concerns about this issue.
"The first set of data is the grain output. In these years, our country ’s grain harvest has been bumper year after year, and it has been stable at more than 1.3 trillion catties for five consecutive years. Last year, the grain output was 1.3277 trillion catties, a record high. The second set of data is the per capita food possession . Since 2010, our country's per capita food consumption has continued to be higher than the world average. In 2019, it exceeded 470 kg, far higher than the international food security standard line of 400 kg per person. "Wei Baigang introduced that the third group of data is food inventory the amount. At present, our country ’s food stocks are sufficient, and the stock consumption ratio is much higher than the 17% -18% safety level proposed by the Food and Agriculture Organization of the United Nations. Especially for the two major rations, wheat and rice stocks are roughly equivalent to the annual consumption of the people of the country. The fourth set of data is China's cereal imports. Our country ’s annual grain imports are not large. Last year, net imports were 14.68 million tons, equivalent to less than 30 billion catties, accounting for only about 2% of China ’s cereal consumption. Our main imports are strong gluten wheat and Thai rice. The main purpose is to adjust the demand structure and better meet the personalized and diversified consumption needs of people.
Eating toon will poison and cause cancer
Yangchun April is a great time of the year. In this season, a long-awaited food ingredient finally matures, it is toon.
"Toon contains more nitrate and nitrite. Improper consumption can cause poisoning and severely increase the risk of cancer." Every year when the toon season is eaten, some rumors spread, especially in the family group Here, "occupying a place" has caused many people who love toon to worry.
Will eating toon be poisoned and cause cancer? In this regard, He Yuhan, a researcher at the Shenzhen Institute of Agricultural Genomics, Chinese Academy of Agricultural Sciences, said that toon does contain a certain amount of nitrite, but it does not mean that it will cause cancer. Nitrite is widely found in nature, and many plants absorb the soil during growth The nitrogen element is converted into nitrate and nitrite, so a certain amount of nitrite will be present in many vegetables.
"In daily life, we eat" toon buds ". As the toon grows, the nitrite content will gradually increase, and the" toon buds "we eat is the period with the lowest nitrite content. At the same time, nitrite Metabolism in the body is relatively fast, as long as the intake does not exceed the daily allowable intake level of the international standard, it does not have much impact on the body. "He Yuhan said.
The allowable daily intake of nitrite set by the World Health Organization and the Food and Agriculture Organization of the United Nations is 0.13 mg / kg body weight. An adult with a weight of 60 kg who wants to eat toon to eat nitrite poisoning needs to eat at least about 1.6 kg of toon.
He Yuhan introduced the safe eating method of toon: "First choose the young 'toon buds", and secondly boil the water before eating. If the amount is larger, you can boil the water and freeze it separately. Try to eat it within half a month. Friends who eat pickled toon, it is recommended to pickle it after 20 days of pickling to reduce the content of nitrite. "
Fresh toon buds can still be eaten with confidence, but it should be reminded that some people may be allergic to toon themselves. The severity of the allergy is determined by their sensitivity to toon. Some people may have respiratory edema after allergy to toon. There are often cases of difficulty breathing, dizziness, etc., and even severe suffocation, so those with severe allergies need to seek medical treatment in time. Therefore, it is recommended that people with allergies or healthy people should eat less or not toon when the body resistance is poor and the body is unwell to avoid allergic symptoms.
