1/ 3 families will throw away the food they can't finish. A survey of food in a primary school in Hang Cheng

Zhejiang Online on October 17 th Yesterday was the 27th World Food Day. The Food and Agriculture Organization of the United Nations set "the right to food" as the theme of this year's Food Day-"Everyone has the right to get enough food", but today's children living in superior families simply can't imagine that there are still 851 million people in the world who lack enough food and are suffering from hunger. Their hunger for food is beyond ordinary people's understanding.

how many leftovers will each school and family produce in a year? How to deal with these endless meals? Yesterday, Zhaohui Experimental Primary School in Hangzhou conducted a survey in the school cafeteria and some students' families, and found that 1/3 families threw away the food they couldn't finish, which was surprising.

1/3 of the families throw out the food they can't finish

"How do you usually handle the leftovers?" Yesterday, Zhaohui Experimental Primary School conducted a random survey among 81 students' families in the fifth and sixth grades, and nearly 1/3 of them said they would throw out the food they couldn't finish.

In the survey, only three families said that they "cook as much as they need" every day, so there are basically no leftovers and leftovers, while other families have different amounts of leftovers every day.

"Yesterday, our dinner was almost the same as usual, with 1.5 of pork, 1.3 of bean sprouts, 1.2 of vegetables and 1.3 of vegetable soup. My mother lost weight, only half of the meal was eaten, and my father didn't finish it." "What does it matter if the food can't be eaten? Our family has leftovers every day, which can be used to feed the kittens and puppies at home. " There are also children who say that only grandparents will put the food they can't finish in the refrigerator and take it out to heat it up the next day, while mom and dad will dump the overnight food.

Similar waste phenomenon also exists in schools. "If the food is to students' taste, they will eat more, but if it is not to their taste, there will be more food left." The master of the school canteen estimated that the leftovers dumped every day in each class were about half a catty.

"There are 12 classes in this campus. According to this figure, 3 kilograms of leftovers are thrown away every day, which is 91 kilograms in a month and 1181 kilograms in a year." The children calculated an account based on this, and the result surprised them.

"If there are no special circumstances, students are not allowed to pour meals. I thought that the amount of leftovers and leftovers dumped would not be too much, but the calculated figures are still amazing." Wang Jun, vice president of Zhaohui Experimental Primary School, said that in general, when distributing meals to children, teachers will ask for students' opinions. For children with small meals, teachers will give them less food. "This is to avoid waste, but because the meals in each class are basically supplied equally, the problem will still exist."

Overnight meals are not nutritious and lack of scientific evidence

"It is said on TV that leftovers are not easy to digest even after heating, and it is very likely that you will get stomach trouble if you eat them frequently." "Leftovers don't cost much, but it's not worthwhile if you eat a bad stomach." "Even if the taste of the overnight food has not deteriorated and the nutrients are gone, it is better to throw it away." In the questionnaire, parents who choose to throw away leftovers list various reasons, but most people still consider it from the perspective of nutrition.

"These ideas are not scientific." Dr. Fu Yunxing, director of the Nutrition Department of Run Run Run Shaw Hospital, said that it is recommended that you don't leave meals overnight, mainly for health reasons. "After rice is left for a day, only water is lost, while vegetables and meat are left overnight, nutrients will not change."

"But the storage time of leftovers should not be too long, because in general, high-temperature heating can kill some bacteria and viruses, but if the storage time is too long, the bacteria in food will release chemical toxins, especially in summer, microorganisms grow rapidly, and contact between different foods is more likely to grow bacteria." Director Fu said that the processing method of leftovers is very important. For example, after the food in the refrigerator is taken out, it must be returned to the pot. "Of course, it is best to have a general understanding of the family's eating habits and food intake, and measure the rice according to the number of people in the family, and try to avoid leftovers."
