People admire all kinds of natural foods. This is not only a consumer fashion, but also represents people's consumer psychology. However, natural foods are by no means equivalent to safe, hygienic and green foods. Some natural foods contain ingredients that are unfavorable to human health---harmful biologically active substances. The so-called biologically active substances refer to those substances that can cause various biological effects after interacting with the body. These substances can be produced by the human body or enter the human body from the outside. Many natural foods contain such substances, some are beneficial to the human body, and some are harmful to the human body. Therefore, when choosing food, we must master the correct understanding method.
In our country, it is generally believed that what is natural is good, but the fact is that foods or additives processed from natural resources may not necessarily be safe and hygienic green foods. Because many natural plants have more or less harmful ingredients. Natural plants are affected by polluted soil, water, air, pesticides and other factors, and some harmful ingredients will remain in the plants. Moreover, if natural plants do not have strict quality control in the process of planting, harvesting, storage and production, it is even more difficult to ensure their food safety. Therefore, it is wrong to hold the concept of "natural is safe" for food. The reason for holding this old concept of food selection may come from the traditional Chinese dietary concept for thousands of years.
With the continuous advancement of nutritional science research, human understanding of food has gradually improved. Food not only contains nutrients needed by the human body, but also contains some toxic substances. Therefore, when choosing food, we must first pay attention to the safety of food. Nowadays, the living environment of the society is seriously deteriorating. Even pure natural fruits and vegetables may have residues of various pesticides, heavy metals and other toxic ingredients. If these toxic ingredients are not removed, they will endanger health. Therefore, the concept of green food was proposed from the perspective of maintaining human health.
The market rushes to publicize and beautify the commercial hype of "pure natural food", which is a kind of misleading to consumers. You must know that purely natural foods are not necessarily green foods, and these two food concepts must not be confused. When choosing any food, you must first pay attention to safety issues. If you can't ensure the safety of eating, "pure natural" will lose its meaning. Green food is the guarantee of dietary safety. Pure natural food may not guarantee dietary safety. From the perspective of food safety, pure natural food does not have natural advantages.
