Advantages and disadvantages of raw vegetables

In recent years, many newspapers and magazines have described raw vegetables as beneficial, able to prevent cancer even from disease, and can improve insomnia, memory loss, aging, and high blood pressure. The basis is that fresh vegetables contain antiviral, bactericidal, and body-strength substances that have low tolerance to heat and are easily destroyed when heated.

It is true that eating raw vegetables can keep the nutrients from being destroyed by heat, so that it can absorb more nutrients and it is indeed beneficial to the body. But this is only one side of things, and you should see the other side of things.

We know that the entire growth process of vegetables is inseparable from fertilizers. The organic fertilizers commonly used in rural areas in China are mainly feces, garbage, etc., which contain a large number of diarrhea, typhoid, tuberculosis and other viruses and hepatitis, influenza, polio and other viruses. There are dozens of pathogens such as locusts, hookworms, and insects, and these pathogens are easily attached to vegetables through fertilization. In addition to the widespread use of pesticides, vegetables contain certain residual pesticides, vegetables contaminated with pathogens and pesticides, and raw materials. After eating, it is very easy to cause the disease. Some vegetable vendors, for the sake of making money, wash the vegetables in the sewage of the ponds and even wash them with sewage discharged from hospitals, factories, etc., and a large number of toxic pollutants are attached to them.

Contaminated vegetables, despite being washed with tap water several times, are not completely removed. Moreover, urban tap water is not "polluted water". Therefore, raw vegetables washed with tap water are still harmful.

The practice of eating raw vegetables such as radish, beets, cauliflower, mushrooms, and bean sprouts abroad is due to the fact that they are non-pollution vegetables cultivated by the “pollution-free cultivation method”. Of course, raw food is beneficial, while the production of non-polluted vegetables in China is not yet widespread. Promotion. At present, according to the specific conditions of the production of vegetables in our country, it is not desirable to eat raw vegetables because of more disadvantages.

Obviously, it is not advisable to promote raw vegetables in our country at present. In order to keep vegetables from being damaged by heat, cooking methods and techniques should be taught. We must not eat raw vegetables to satisfy the taste.
