So do sweet potatoes really fight cancer? Will eating too much affect your health? Let's take a look at it together.

Japanese research has found that sweet potatoes can destroy 98% of cancer cells, is there a scientific basis? Tell you the truth
There are many "anti-cancer food rankings" circulating on the Internet, sweet potatoes are ranked first, and some articles point out that the anti-cancer rate of sweet potatoes is as high as 98%, and many middle-aged and elderly people are convinced. Can eating sweet potatoes really fight cancer?
The reason why sweet potatoes fight cancer has to start with a Japanese study, researchers from the National Cancer Prevention Institute of Japan followed up the eating habits of 260,000 people, and found that vegetables do have a certain anti-cancer effect.
The researchers ranked the anti-cancer effects of different vegetables through analysis, among which sweet potatoes ranked first, claiming to have a 98% inhibition rate against cancer cells. Since then, the anti-cancer effect of sweet potatoes has been wildly spread.
So the efficacy of sweet potatoes is constantly exaggerated, and it is rated as the "king of anti-cancer", so is sweet potatoes really so amazing that they can kill cancer cells? It's not magical.
The extracts in the sweet potatoes used in the study were carried out in vitro experiments and could not be directly extrapolated to the human body, and the extracts used in the experiments were completely different from the sweet potatoes we ate, and it was not feasible to eat sweet potatoes.
The main component of sweet potatoes is starch, sweet potatoes can be eaten as a staple food, and the protein amino acid structure in sweet potatoes is more reasonable, and rice noodles can improve protein utilization.
In addition, sweet potatoes are rich in dietary fiber, and eating sweet potatoes appropriately can help prevent constipation, and can also relieve people with constipation.
In short, the claim that sweet potatoes can destroy 98% of cancer cells is unscientific, and the mainland has not released any relevant studies showing that sweet potatoes can fight cancer.

But you can't just eat sweet potatoes, because sweet potatoes contain low protein content, can not be compared with staple foods such as rice and flour, long-term eating sweet potatoes can easily lead to insufficient protein intake, which is not good for health.
The claim that sweet potatoes can lower blood sugar is also unreliable, because the glycemic index of cooked sweet potatoes can reach 76.7, as long as it is higher than 70, it is a high-sugar food.
The reason why sweet potatoes lower blood sugar is because sweet potatoes contain lower carbohydrates and calories than refined rice noodles, but sweet potatoes cannot be counted as blood sugar lowering foods.
