So is that true?

Are all the anti-cancer "rumors" circulating on wechat credible?

The principle of carcinogenesis is that some green leafy vegetables contain more nitrate. If they are cooked for a long time, nitrate will be reduced to nitrite under the decomposition of bacteria. Nitrite is carcinogenic and cannot be removed by heating.

Second: the truth: wrong Professor Luo Rongcheng, President of Southern integrated Chinese and Western Medicine Hospital of Southern Medical University, said that the first thing to be clear is that nitrite does not cause cancer, but nitrite may be converted into nitrosamine in the human body, and nitrosamine is a carcinogen. But generally speaking, the metabolism of nitrite in the body is very fast, unless it is a large amount of one-time intake, it will cause poisoning (methemoglobinemia), so the normal intake of nitrite in normal people will not be toxic. In addition, the conversion of nitrite to nitrosamine needs certain conditions, and the reaction can be prevented by adequate intake of vitamin C and vitamin E. Although the "theory of overnight food causing cancer" does not hold, Professor Luo Rongcheng suggests that, from a health perspective, overnight food, especially overnight vegetables, is not only low in nutritional value, but also easy to deteriorate. It is better to eat less or not, and eat as many fresh vegetables as possible. The reason is that the biggest disadvantage of overnight food to health is the loss of nutrition, easy to breed bacteria, causing gastrointestinal inflammation.

Third: Wuxing vegetable soup prevents and cures cancer Original text of wechat: the five kinds of vegetables selected in the soup have five colors, representing the five elements of wood, fire, earth, gold and water. They correspond to the five zang organs of liver, heart, spleen, lung and kidney in the human body. After taking the soup, it can balance the five zang organs, effectively inhibit cancer, inject vitality and vitality into life, and even achieve the magical effect of "cancer cell activity stops in three days, functional recovery in one month" Curative effect.

"Studies have shown that when the concentration of organic sulfur compounds reaches 40 μ g / ml, it can effectively inhibit Helicobacter pylori infection. The smell of onion and garlic that we usually smell is emitted by organic sulfur compounds. In addition, flavonols can help the human body degrade carcinogens. All these show that onion and garlic can be used as one of the effective methods to prevent gastric cancer
