Eat more purple sweet potato can really fight cancer?

The purple sweet potato was popular on the market. According to an internet encyclopedia, “it has rich nutritional elements including selenium and anthocyanins, as well as common sweet potato nutrients. Anthocyanins have a preventive and therapeutic effect on more than 100 diseases and are known as water, proteins, and fats. The seventh most important nutrient after sugar, vitamins, and minerals. Anthocyanins are the most direct, effective, and safest free radical scavengers in the scientific community today to prevent diseases and maintain human health." , Eat more purple sweet potatoes can play an anti-cancer effect.

In fact, to date, whether anthocyanins are resistant to human-made tumors still lacks scientific evidence.

Purple sweet potato does contain many anthocyanins. In fact, most higher plants contain anthocyanins, which are the products of plant metabolism. In addition to purple sweet potatoes, eggplant, blueberry, red (violet) grapes, cabbage, purple corn and other blue-violet vegetables and fruits have high anthocyanin content. In different acidity and metal ion environments, the plant absorbs parts of different wavelengths in sunlight, giving the plant a red, blue or purple appearance.

In chemical experiments or cell experiments conducted in the laboratory, anthocyanins also exhibit powerful antioxidant properties. Many people have conducted research on this, and many related scientific papers have been published. It has been confirmed that the antioxidant damage of cells is related to the occurrence of many chronic diseases such as cancer and aging. In general, anthocyanins have been used to cultivate cancer cells in vitro. Showed a strong inhibitory effect; for experimental animals such as mice, anthocyanins also showed some resistance to artificially induced tumors.

However, there is still lack of evidence for the existence of anthocyanins in the human body. Italian scientists have conducted "case-control" studies comparing the dietary status of thousands of cancer patients with "normal" people who have similar conditions but no illness, and have not found "effective" in blue-violet vegetables such as anthocyanins. "Ingredients" are related to cancer. Some scholars have also suggested that once anthocyanins are eaten into the body, they may not be able to exert their effects. The current allegations of the anti-cancer effect of "anthocyanins" are actually derived from the "antioxidant" theory, and there are no direct clinical trial data.

Cell experiments and animal experiments can give scientists some research directions, but they still cannot provide valid evidence. In the United States, there was a company that advocated the “special effect” of a blue-violet fruit and the result was severely warned and stopped by the Drug and Food Administration.

Of course, this does not mean that there is something wrong with purple sweet potato. Any vegetable or fruit, whether blue-purple, green or yellow, is good for human health. However, for modern urban people, the main reason why vegetables and fruits can't exert their due effects is "insufficient consumption." Therefore, it does not matter what kind of vegetables you choose to eat. What is important is that we should increase the amount of various fruits and vegetables in the recipe.
