Why do Americans eat green bananas?
Speaking of bananas, everyone's impression is "yellow" and "fragrant and soft". If you buy a green banana, most people will not eat it, but leave it for a few days until it matures and turns yellow.

But if I told you that eating one of these "green bananas" every day might reduce the risk of cancer, would you believe it? Related studies have published similar views.

University joint research: Eating a "green banana" every day reduces the risk of multiple cancers by 60%.

This paper was published in Cancer Prevention Research and was jointly studied by Newcastle University and Leeds University. Through the statistical analysis of the research data of the subjects, the comprehensive anti-cancer rate can reach about 60% by eating a "green banana" every day, such as cancers such as intestinal cancer, gastric cancer and gallbladder cancer.

A small "green banana" is not even fully mature. Why can it fight cancer? In this regard, the researchers found through further analysis that the key lies in the "resistant starch" contained in green bananas.

Coincidentally, Rodney, a professor of biology at Johns Mures University, found that the content of resistant starch in green bananas was about 17%. With the anti-cancer effect of resistant starch, the risk of digestive tract cancer can be reduced by about 20% in daily diet.

It can be seen that no matter what kind of experiment, the substance "resistant starch" is mentioned.

What is "resistant starch" and why does it reduce the risk of cancer?

The biggest difference between resistant starch and ordinary starch is that it does not need small intestine digestion. After the resistant starch enters the colon, it is fermented by bacteria to produce "butyrate" substance.

Butyrate in intestine can promote the enhancement of intestinal function and improve the survival efficiency of beneficial bacteria in intestine, thus protecting digestive system and maintaining gastrointestinal function. Therefore, taking resistant starch for a long time can effectively prevent digestive system cancers such as intestinal cancer, gastric cancer and gallbladder cancer.

Dana Faber Institute in the United States once conducted an experiment: nearly 9,000 subjects were recruited and divided into two groups. One group ate resistant starch every day, and the other group ate a placebo.

Twenty years later, it was found that the risk of colorectal cancer in the "resistant starch group" was about 50% lower than that in the "placebo group".

It can be seen that "green banana" rich in resistant starch may have a good anti-cancer effect on some cancers. Friends in need can eat it properly, which will bring benefits to the body.

However, not everyone is suitable for eating green bananas. Although it has a certain anti-cancer effect, some people should be careful when eating it.

These three types of people are not suitable for eating "green bananas"

① Obese people

Although green bananas contain more resistant starch, at the same time, because they are not mature, the sugar concentration will be higher.

Therefore, if obese people eat green bananas every day and their fructose intake exceeds the standard, it will easily lead to an increase in blood sugar and induce the risk of diabetes and its complications. Therefore, obese people had better try to eat low-sugar fruits such as apples and grapes.

② Patients with liver and kidney diseases

Liver and kidney are important components of human metabolic organs. If there are liver and kidney diseases, the body's ability to bear the metabolic burden will also be weakened.

Before the green banana matures, many nutrients are wrapped in the cell wall, which is difficult to metabolize. In addition, bananas are rich in potassium, which will undoubtedly further increase the metabolic burden of the liver and kidneys.

Therefore, friends with liver and kidney diseases are not recommended to eat green bananas, so as not to aggravate the condition, but it is not conducive to health recovery.

③ People with indigestion or constipation.

The difference between green bananas and mature bananas lies in the content of "resistant starch" and tannic acid.

Green bananas are rich in tannic acid. For people with indigestion or constipation, the diet should be easy to digest and don't bring too much digestive burden to the stomach.

A large amount of tannic acid intake will combine with protein of human body, thus forming the burden of sediment, leading to indigestion and constipation, so it is not recommended to eat.

To sum up, although green bananas have anti-cancer ability, some people still don't recommend eating them for the sake of health. However, this is not an opportunity for everyone to give up fighting cancer. The main anticancer component of green banana is "resistant starch", and other foods also contain resistant starch, so you can choose.

These foods also contain "resistant starch" and can be eaten as substitutes.

Generally speaking, foods with high starch content contain more resistant starch. The lower the calories of food itself, the higher the proportion of resistant starch.

Therefore, coarse grains such as sweet potatoes, oats and corn contain high starch and not too much calories. Supplementing resistant starch is a good choice.

There are all kinds of green leafy vegetables. It is also a good choice for supplementing resistant starch and taking vitamins.

However, it should be noted that it is also possible to process some "coarse grains", such as sweet potatoes and sweet corn. Eating too much leads to high blood sugar, which is not good for your health. The choice of coarse grains, as far as possible to the original flavor, the original ecology-based, do not covet the taste and lose health.

If you want to actively prevent cancer, diet is the key link. Choosing proper and balanced food and keeping healthy are the keys to overcoming cancer.
