Is sweet potato leaf really an anti-cancer artifact?

It has been proved that this is a rumor. Don't believe it.

In recent years, there has been a "sweet potato leaf fever" in Europe, America, Japan, Hong Kong and other places, and foods made of sweet potato leaves have been put on the dining tables of hotels and restaurants. Sweet potato leaves are one of the common vegetables in Bama County, China, also known as "longevity vegetables".

It is said that sweet potato leaves are rich in nutritional value, which can detoxify, enhance immunity, prevent hypertension, improve constipation, improve menopausal symptoms and prevent anemia. The polyphenols contained in them have miraculous effects on cancer.

In fact, the so-called "polyphenol anti-cancer" comes from cell experiments, which does not mean that eating polyphenols can fight cancer. Similar to antioxidants, sweet potato leaves contain more polyphenols, but not higher than all kinds of green vegetables, tea, coffee and other foods and drinks. As a vegetable, sweet potato leaves are really good in nutrients, and as a part of diversified recipes, sweet potato leaves are a very "excellent" vegetable.

However, it is not omnipotent and has no magical effect. We can't exaggerate the efficacy of any food ingredients, because the value of food is a comprehensive embodiment of various nutritional ingredients.

The staff of the US Food and Drug Administration in Bama Yao Autonomous County, Guangxi Zhuang Autonomous Region, said that eating sweet potatoes and sweet potato leaves has been a dietary habit of local residents for many years, but it is not for longevity and anti-cancer, and it has never been heard that sweet potato leaves have anti-cancer and longevity effects.

Yun, a doctor of food engineering, believes that as a vegetable, sweet potato leaves have better nutritional components. In addition, sweet potato leaves do not have "magical effects" such as anti-cancer and blood purification. Yun unintentionally said that the so-called "sweet potato leaves contain polyphenols and can fight cancer" is derived from cell experiments, not that eating sweet potato leaves containing polyphenols can "fight cancer". Although there are many polyphenols in sweet potato leaves, the contents of polyphenols in other vegetables, tea, coffee and other foods and beverages are not low.
