Can chestnuts still prevent cancer?20 -year follow -up research proves that this nutrient is the key

Locate chestnuts in autumn, and the scent of sugar fried chestnuts will be permeated in the streets and alleys.Thinking of the glutinous texture, the sprayed aroma will flow out inadvertently.

However, the tempting chestnuts are not only delicious but also unexpected: significantly reduce the incidence of colorectal cancer. What is going on all?

Resistant starch

It’s the merit of chestnut anti -cancer

Recently, the research team of the University of Newcastle University in the United Kingdom found based on 20 years of data tracking and found that long -term anti -resistant starch can significantly reduce the incidence of condensing gastrointestinal cancer.

So, what is resistant to starch, what does it have to do with chestnuts?

Anti -starch is not a very new concept. It is defined as a starch group that cannot digest and absorb the human stomach and small intestine.

This also means that although it is a genuine starch in chemical structure, it cannot be broken down by the human body into glucose, nor can it be absorbed into the blood.

Of course, if the small intestine does not digest it, it will enter the large intestine more completely, and then the probiotics in the large intestine will welcome it very well, and become prosperous because of "sufficient food", becoming a relatively strong flora.

In fact, resistance starch is a kind of dietary fiber that we are very familiar with, and the chestnuts are exactly rich in this dietary fiber. 78%of the starch content in the chestnuts are resistant starch.

However, if you expect to eat one or two chestnuts to prevent cancer, it is tantamount to dreaming!

The research team of the University of Newcastle in the United Kingdom found that the results of taking resistance starch for 2 and 10 years were similar, and it was not significantly surprised, indicating that the effect of taking resistance starch in the short term was not obvious.

However, after 20 consecutive years, it was found that whether it was colorectal cancer, or other digestive tract cancer (such as gastric cancer, bile duct cancer, and pancreatic cancer, etc., the resistance starch group had a lower incidence.

To be honest, eating chestnuts for 20 consecutive years, economic strength is not allowed. After all, the price of chestnuts is not cheap now!

In addition, although chestnuts are delicious and highly nutritious, eating too much will damage health.

1. Affects blood sugar

Although the chestnuts are nuts, the content of carbohydrates is a bit high. Each 100g chestnut contains 42.2g of carbohydrates.

Therefore, when eating chestnuts, you should avoid eating too much, especially people with diabetes, so as not to affect the stability of blood sugar.

2. Cause stomach bleeding

Because chestnuts are similar to coarse grains, they will quickly be fermented in the gastrointestinal tract after consumption, and it is prone to flatulence and snoring when eating too much.

If the amount of food is too much or the people have gastrointestinal diseases itself, then it is easy to cause vomiting caused by severe gastrointestinal flatulence, or even gastric bleeding.

3. Digestiveness

Although chestnuts are rich in nutrition, eating too many chestnuts and not easy to digest, and eating too much is easy to stagnate. In particular, people with poor gastrointestinal function and digestive system diseases should not eat more, so as not to aggravate the condition.

Dietary fiber is a good choice for anti -cancer

Whether it is economical or practical, it is unrealistic to prevent cancer by eating chestnuts. So is there a feasible way?

The reason why resistant starch in chestnuts can prevent cancer is that it can regulate intestinal metabolism and promote the reproduction of probiotics in the intestine and produce a good health protection effect.However, supplementary dietary fiber can also achieve these effects.

The World Health Organization International Cancer Research Agency released 19.31 million cases of colorectal cancer in 2020, ranking third and 935,000 deaths in the second place.

Studies have found that the risk of 10 grams of dietary fiber colorectal cancer daily decreases by 10%, and 30 grams per day can decrease by 17%.Studies have shown that they insist on taking more full -dietary fiber every day, and the risk of colorectal cancer decreases by 16%to 43%.

Why can dietary fiber effectively prevent colorectal cancer?


Due to the strong water absorption of dietary fiber, after absorbing a lot of water, the volume and weight of the feces will be increased accordingly, thereby objectively diluing the concentration of carcinogens in the intestine and reducing the possibility of cancer.


Dietary fiber can shorten food and residue through the operating time of gastric mucosa to accelerate the passage of internal toxins in the intestinal cavity.Low fiber diet increases the time of the colon, and the contact time of carcinogenic substances with intestinal walls is greatly improved.


Dietary fiber can promote the metabolism of bile acid.Bile acid is considered to be the most likely pathogen of colorectal cancer, playing a key role in the occurrence of colorectal cancer.


Dietary fiber can effectively promote the reproduction of probiotics, thereby maintaining the intestinal ecological balance and the integrity of barriers.At the same time, the immune response can be improved through probiotic activation immune system.Once an abnormal cell (such as tumor cells) appears, the immune system will be monitored quickly, and the immune response occurs.

The Chinese Nutrition Society recommends that daily dietary fiber intake is 25 ~ 30 grams. However, the per capita daily intake of Chinese people is only 13 grams, and less than 5%of people who can reach 25 grams of daily intake.

This means that 95%of people have not reached the appropriate intake of dietary fiber. Some people may be confused: dinner fruits and fruits, why do dietary fibers still not meet the standard?

In fact, although vegetables and fruits are rich in dietary fiber, if the daily intake of dietary fiber is 25 ~ 30 grams, it is equivalent to eating 10 bananas or 5 peaches a day.

Ten bananas a day are undoubtedly a huge challenge. Even if it is really done, it may not be able to eat blood sugar.Therefore, it is unrealistic that it is unrealistic that it is unrealistic that it is unrealistic that it is unrealistic to meet the needs of dietary fiber simply through vegetables and fruits.

So, is there any other good way to supplement a sufficient amount of dietary fiber?Yes, dietary fiber supplements!

If you want to supplement dietary fiber, you may wish to try light and health. The main raw materials of the dietary fiber in the front shell of the bud car are as high as 80%, which has the reputation of "the king of dietary fiber".

It is not advisable to meet the physical needs of dietary fiber through vegetables and fruits. Therefore, if you want to reduce the risk of colorectal cancer, dietary fiber supplements eat!
