An "anti-cancer fairy soup" is being hotly debated on the Internet. It is cooked with spinach, tomatoes, celery, carrots and onions, and there is a strange way to eat it, "only soup without vegetables." In this regard, the doctor said that these are common vegetables, each with nutritional value, but together they can prevent cancer, which is exaggerated and has no scientific basis.

Online rumors that celery, tomatoes, onions and other boiled soups help fight cancer have no scientific basis.

Netizen "Tashi Landuoduo" recently said in Weibo that this year he learned to make an "anti-cancer fairy soup" that can slowly turn acidic constitution into alkaline constitution, using 2-3 liang of spinach, 2-3 liang of tomato 1 piece, 2 liang of celery, 2 carrots and 1 onion 1 piece. He only drinks soup, not vegetables. According to online legend, cancer cells in human body are not easy to grow and reproduce in alkaline environment.

The above-mentioned Weibo caused netizens to watch, and the forwarding volume quickly exceeded 10,000. However, many experts believe that the so-called anti-cancer soup is groundless. Among them, Tian Bingru, director of the Oncology Department of Yuyao People's Hospital in Ningbo City, Zhejiang Province, said in an interview with Yuyao Daily that "there is no specific medicine for preventing cancer in medicine. 」

Tian Bingru pointed out that the ingredients used in anti-cancer soup are common vegetables, each with its own nutritional value. Celery, for example, is rich in cellulose, which helps to clear the bowels and relieve constipation. Onions have antibacterial effect, but it is too exaggerated to add several vegetables together to prevent cancer.

Tian Bingru emphasized that the best way to prevent cancer is to improve living habits and avoid staying up late for a long time; Increase exercise and improve the body's immunity; Adjust the diet structure, eat less high-protein and high-fat foods, and quit smoking and drinking; Adjust mood, decompress yourself, etc. As for the formulation of "improving acidic constitution" in anti-cancer soup, Tian Bingru said that this is not consistent with the acidity and alkalinity of the human body in medicine.

According to reports, under normal physiological conditions, the pH value of blood is just kept between 7.35 and 7.45, showing a weakly alkaline state; Once the pH value of human blood is lower than 7.35, acidosis will occur, while when the pH value is higher than 7.45, alkalosis will occur. Both acidosis and alkalosis are caused by some diseases, which lead to the destruction of normal physiological metabolism.

Tian Bingru said that the acid-base balance of the human body is automatically regulated by endocrine, excretion and absorption, and can not be changed by several foods.
