What is organic food?
When referring to "organic foods," many people will have the idea that "although it is expensive, but because it is safe and it feels more comfortable to eat", there have been frequent food safety accidents in the past four or five years in the country and "eat safely" has become The primary goal for less consumers to purchase ingredients.
The reason why people think that organic foods are safer is because in China, foods that are truly organic food certified, produced and processed without the use of synthetic substances such as pesticides, chemical fertilizers, and chemical preservatives, have to be grown in soil for 3-5 years. Recessions range from unrecovered pesticides and fertilizers, so organic foods can be said to be truly natural foods.
Organic foods are healthier?
Because organic foods are several times more expensive than regular foods, according to the “one dollar, one share†value, people generally think that organic foods are not only safer but also more nutritious. However, Wang Xingguo, director of the Nutrition Department of Dalian Central Hospital, stated in his blog: “According to the data I understand, organic vegetables and non-organic vegetables are not much different. Therefore, the advantages of organic vegetables are more secure.†China Agricultural University Food Science and Nutrition Zhu Yi, an associate professor of engineering, pointed out that organic foods are slightly better than normal foods in the content of some antioxidants, but it is not necessary to use a few times the price to pursue a slight gap.
Organic food is safer? Japanese scholars have doubts
Compared with domestic experts, Lu Changyan, an associate professor of the Faculty of Agriculture at Kinki University in Japan, pointed out that based on the perception that “organic food is saferâ€, many people think that there is a safety risk in the general food industry, but this is a misunderstanding. He believes that from the perspective of risk science, the theory that “organic foods are safer without using pesticides and fertilizers†or “general foods using pesticides and fertilizers is dangerous†is not established.
Strictly speaking, agricultural products also belong to plants, and they have biological defense reactions that they own. The plants can create their own "natural pesticides" to protect their own safety. When harmful insects, plants will automatically trigger a living defense reaction, produce a variety of substances, some pesticides is extracted from these substances, produced by chemical synthesis. He said that "organic foods are more beneficial to human health" or "organic foods are safer" is essentially similar to the "placebo effect," giving people more psychological comfort.
Wang Xingguo stated in his blog: “I can only say that the conditions and environment for planting vegetables, especially in northern greenhouses or in greenhouses, are relatively unreliable and it is hard for people to rest assured. My support of organic vegetables does not mean that I would deny ordinary vegetables. As in the field, food consumption is also diversified. Consumers can choose according to their own circumstances.†Zhu Yi said she agrees with Japanese scholars. She said: “According to the current level of environmental pollution in China, organic foods are not really safer than ordinary foods. Imagine that even if you do not use fertilizers and pesticides, soil, water and air are seriously polluted. What about safety? The reason why we promote organic food is not based on the perspective of food safety, but is promoted from the perspective of promoting the sustainability of agricultural development."
Why promote organic food? How to buy organic food?
Prof. Kazuhiko Ryouh, with the same opinion as Prof. Zhu Yi, said that the use of pesticides and fertilizers in agricultural production will pollute the environment around the farmland, reduce the number of individual organisms around the farmland, and lose biodiversity, which in turn will lead to deterioration of the production environment and production quality. Decline. Organic foods do not use pesticides and fertilizers in the production process, which is conducive to protecting the environment and promoting sustainable development. This is the biggest reason for advocating the development of organic foods.
Zhu Yi reminded the consumers that the most stringent food safety law is about to be introduced, requiring that every organic food that has been audited in China must have its own "ID number", which is a bar code block. She reminded consumers that the purchase of organic food cannot be counter-productive. We must look for organic food “identity cards†and enter the China Food and Agricultural Products Certification Information System to inquire whether the “ID card number†is true and we can determine whether the purchase of organic food is truly organic. food.
