A Japanese study found that sweet potatoes can eliminate 98% of cancer cells. Is there any scientific basis? the truth is coming
Sweet potato, commonly known as sweet potato, is the season to eat roasted sweet potato. Sweet potatoes are not only sweet and delicious, but also have high nutritional value. They contain dietary fiber, carotene, vitamin ABCE, potassium, iron, copper, selenium, more than 10 trace elements, such as calcium, with high nutritional value, and are called by nutritionists as the most balanced health food. They are food and vegetables outstanding.
Europeans and Americans praised it as "the second bread", the former Soviet scientists said that it was the future "space food", and the French called it a well-deserved "advanced health food".
In recent years, people's health awareness has become stronger and stronger, and sweet potatoes have gradually become a good health product. Some people think that sweet potatoes can eliminate 98.7% of cancer cells, and regular consumption of sweet potatoes can prevent cancer. Is there any scientific basis for this claim?
Japanese research: sweet potato can kill 98% of cancer cells, is it reliable?
Researchers from Japan's National Cancer Prevention Institute tracked the eating habits of 260,000 people. Studies have found that vegetables do have certain anti-cancer effects. Through the analysis, the researchers ranked the cancer-fighting effects of different vegetables, with sweet potatoes ranking first.
Therefore, the saying of sweet potato anti-cancer has spread, and the efficacy of sweet potato has been exaggerated constantly. It has been rated as the "King of Anti-cancer" and claims that it can kill 98% of cancer cells.
In fact, there was a saying before that sweet potatoes can fight cancer, but animal experiments are also the object of research. The sweet potato was mainly injected in animals, and the extract eventually inhibited the cancer cells in the animals.
Therefore, the extract from sweet potatoes can eliminate 98.7% of cancer cells, but this animal experiment cannot be used in clinical trials in humans, so it cannot be fully believed.
Most importantly, the main ingredient is not sweet potato, but sweet potato extract. Eating some sweet potatoes does help suppress the activity of cancer cells, which is why the extract is.
But in fact, when we eat sweet potatoes, the sweet potatoes will enter the intestines and stomach. During digestion, there is no actual research to prove that we can absorb ingredients similar to sweet potato extract. In short, eating sweet potatoes has no effective anti-cancer substances, and the effect of eliminating cancer naturally does not exist.
