Modern people pay more and more attention to health preservation and slimming. Recently, the trend of drinking vegetable juice for beauty has begun to appear on social networks. It is said that vegetables are rich in antioxidants such as vitamins and minerals, and their sugar content is lower than that of fruit juice.
Because cooking means will lose a lot of water-soluble and heat-sensitive bioactive components, many people think that freshly squeezed vegetable juice can retain nutrients as much as possible.
Moreover, in people's subjective feelings, green itself also gives people a very healthy impression, so many people are convinced that a cup of vegetable juice every day can detoxify and lose weight.
Is the vegetable juice raw or cooked?
It would be better to juice with cooked vegetables. Because cooked vegetables no longer have toxins harmful to people's health, and cooked vegetables will not lose too much nutrition.
Cooked fruit and vegetable juice contains vitamins, cellulose, minerals and other beneficial nutrients, which can meet the needs of human body and provide energy for human body.
The practical function of drinking a cup of vegetable juice every day
But to everyone's disappointment, many cases show that drinking vegetable juice can not only "detoxify", but also cause damage to many organs such as kidneys, causing abdominal pain, diarrhea, hematemesis and other symptoms, and even severe acute renal failure.
In fact, some dishes need to be cooked. During the heating process, not only the nutrients are lost, but also some substances, such as lectin, tannin, cucurbitacin and oxalic acid, are lost.
They were originally "protective umbrellas" to protect plants from microorganisms and insects, but they have become "toxins" of people.
Tannin should be familiar to everyone, that is, persimmon produces astringent substances. In addition to persimmons, immature grapes, plums and other tannins are also relatively high.
Too much tannic acid will combine with protein to form protein tannic acid. In the case of hyperacidity, it will be mixed with pectin and fiber to form lumps.
If these lumps remain in the stomach, the stones formed cannot be discharged naturally, which will cause digestive tract obstruction, leading to severe pain in the upper abdomen, vomiting and even hematemesis.
Similarly, some leguminous vegetables, such as kidney bean, edamame, broad bean and potato tuber, contain toxic protein which can agglutinate red blood cells. These protein are lectins.
In addition, oxalic acid is easy to form calcium oxalate with calcium ions in human body, which will not only lead to kidney calculi, but also these calcium oxalate crystals will be randomly deposited in the body like a small knife, causing wear and tear of various tissues and organs of the body. Vegetables with more oxalic acid content include spinach, sweet potato, celery and broccoli.
Therefore, squeezing vegetables into juice without any cooking treatment can not "detoxify", but will bring toxins to the body.
Moreover, normal people do not need to detoxify, the immune system can block pathogenic bacteria, and the metabolic waste produced by the human body will be discharged by itself with metabolism and will not accumulate in the body.
In short, detoxification itself is an unreliable statement, and squeezing raw vegetable juice is even more undesirable. If you want to stay healthy, it's more reliable to keep a correct routine and eating habits.
