Why the highly functional prebiotic “kestose” is essential for intestinal activity

腸活に高機能プレバイオティクス「ケストース」が欠かせない理由

The intestines are one of the important organs that support the health of the body, and I think the term "intestinal activity" has become quite popular. It is said to be highly effective for beautiful skin, and is often featured in women's magazines, but intestinal activity is effective for the mental and physical health of all people, regardless of age or gender.

However, many people may not yet know about the highly functional prebiotic ``kestose'', which is essential for intestinal activity.

Kestose is a prebiotic and serves as a nutritional source for beneficial bacteria such as Bifidobacterium in the intestines. Therefore, ``intestinal activity'' that balances the intestinal flora (intestinal environment) can be expected to be highly effective.

Why is it good to clean your intestines?

Since you can't see inside your intestines, I think it's difficult to judge whether your intestinal environment is good or bad.

However, you can judge from the condition of the flight.

If the intestinal environment is in good condition

-Stool color is yellowish brown
・No bad odor ・Banana shape

If the intestinal environment is bad

-The stool is dark in color
・There is a bad odor ・The shape is not stable


``Constipation'', which we often hear about, is a disease, regardless of its severity. If you use easily available laxatives, you may end up having to take the laxatives to have a bowel movement. This will prevent your intestines from growing strong.


Adjusting the intestinal environment and cleaning the intestines

・Less prone to constipation and diarrhea
・Become less prone to gaining weight ・Improve skin problems ・Improve immunity

can be expected.

Less prone to constipation and diarrhea

Stool is a barometer to see the condition of your intestines, so I think you will be able to pass healthy stools regularly and without strain.

Continuing constipation can also lead to other illnesses.

Become resistant to gaining weight

It is said that the Enterobacterium phylum Firmicutes absorbs a lot of energy. It can be said that if there is a large amount of Firmicutes in the intestine, it is easy to become obese.

Also, if you have chronic constipation, your metabolism may slow down, making it difficult for your body to burn fat and lose weight.

Improvement of skin problems

This is related to constipation, and it is said that when stool remains in the large intestine, it rots and bad bacteria increase. Toxic substances, such as ammonia, are absorbed into the body and enter the bloodstream. Some of the blood comes out on the skin as sweat, and the harmful substances contained in sweat can cause skin problems.

By cleaning your intestines, the blood circulating in your body will also be cleansed, which will prevent skin problems.

Increase immunity

“Immunity” is something we hear a lot these days. It is said that 70% of the human body's immune system is located in the intestines. It is no exaggeration to say that in order to protect your body, you must protect your intestines.

A weakened immune system can make you more likely to catch a cold or develop allergic symptoms such as hay fever and atopic dermatitis. It is said that one in two people now suffer from hay fever, and this is said to be due to the weakened immune system of modern people.

By increasing your immunity, you can protect your body from pathogens and maintain your health. When your immune system is working properly, you can maintain a healthy and youthful body.



By cleaning your intestines in this way, you can expect to fundamentally improve your constitution and become healthier.


Bacteria in the large intestine change depending on physical condition and age.

Our bodies are made of what we eat. The intestine is an organ that absorbs nutrients from food.

Nutrients are mainly absorbed in the small intestine. Water is absorbed in the large intestine. However, it turns out that there are more intestinal bacteria in the large intestine than in the rest of the intestine. ``Intestinal activity'' has been attracting attention since research was published that showed that these intestinal bacteria influence our constitution.


Intestinal bacteria can be roughly divided into three types: approximately 20% are good bacteria, 10% are bad bacteria, and the remaining 70% are opportunistic bacteria.

Normally, in a healthy body, good bacteria are active and prevent the growth of bad bacteria. However, if you become unwell or your body is weak, and bad bacteria multiply, the normally docile opportunistic bacteria will start doing the same bad work as the bad bacteria.

Bad bacteria include toxic strains of Clostridium perfringens, Staphylococcus, and E. coli. Opportunistic bacteria, enticed by bad bacteria, start doing bad things such as Bacteroides, Escherichia coli, and Streptococcus.


Humans are born germ-free and receive bacteria from their mothers at birth. More than 95% of a baby's large intestine is made up of Bifidobacteria. This is why the stool of a baby who is drinking only milk before weaning on baby food is yellowish and has no odor.

However, it is said that the number of bifidobacteria decreases with age, and in middle age, the number of bifidobacteria continues to decrease, and in some elderly people it is less than 1%. This may be why as we age, we become more susceptible to illness and find it harder to recover from illness.

In addition to aging, the intestinal environment changes due to small meals and stress, such as overeating and drinking.

How to increase good bacteria

Fermented food image

The good bacteria that decrease with age, and the good bacteria that weaken due to slight changes in physical condition...what can we do to nurture and increase these bacteria?

Obtain living beneficial bacteria “probiotics” from food

Incorporate fermented foods such as yogurt, lactic acid bacteria drinks, natto, pickles, and cheese into your daily meals. However, it is said that it is difficult to deliver ``Lactic acid bacteria'' and ``Bifidobacteria'', which are well-known among the beneficial bacteria, to the intestines alive. Additionally, these bacteria do not colonize the intestines and are excreted daily.

It is necessary to incorporate these foods into your daily menu and continue to consume them every day.

Ingest "prebiotics" that nourish the good bacteria that originally exist in the intestines

These days, oligosaccharides that are available at supermarkets and other places fall under this category.

Contains vegetables, fruits, and legumes. Oligosaccharides reach the large intestine without being digested or absorbed, so they serve as food for the good bacteria we want to increase and grow.

However, oligosaccharides can also become nutrients for bad bacteria.

Therefore, the new carbohydrate ``kestose'' is attracting attention.

Kestose, a highly functional prebiotic that directly reaches useful bacteria that regulate the intestinal environment

Kestose is resistant to stomach acid and bile acid, and is transported to the intestines intact. Although it is difficult to deliver lactic acid bacteria and bifidobacteria alive to the intestines, they serve as food for and nurture the lactic acid bacteria and bifidobacteria that are already in the intestines.

The major difference from oligosaccharides is that they are unlikely to serve as nutrients for bacteria that are harmful to humans. Since it reaches the large intestine undigested, it directly reaches useful bacteria that help regulate the intestinal environment, and is expected to improve the intestinal environment.

Expected effects

・Intestinal regulation effect (improvement of bowel movements)
・Prevention and improvement of viral infection ・Suppression of allergies
Improvement of atopic dermatitis in infants
・Improvement of lifestyle-related diseases ・Prevention of arteriosclerosis ・Prevention and improvement of colorectal cancer and inflammatory bowel disease


Prebiotics are said to have the functions and effects listed above.

Continuous intake is required to experience these effects. Kestos is also excellent in that it can be easily incorporated into daily life and is easy to continue.


Kestose is a highly safe carbohydrate found in familiar foods such as pumpkin, onions, asparagus, barley, and rye. Even small children can eat it safely.

It has a mild sweet taste and is soluble in water, so it is easy to add to everyday drinks or incorporate into dishes.

Nakaya Shoten's Kestose comes in individual packages with a daily intake of 3g, making it easy to use and get used to. Enjoy it in your morning coffee or tea, or add it to yogurt.

Don't rely solely on "Kestose" just because it's a highly functional prebiotic.

Even so, drinking only Kestose will not improve the intestinal environment. It is necessary to incorporate live good bacteria into your diet on a regular basis, such as foods containing probiotics, such as yogurt, natto, cheese, and miso.

The basics are “probiotics” + “prebiotics”!

Consuming the probiotic-rich foods introduced above together with the prebiotic ``kestose'' will be even more effective.

When taken with foods containing probiotics, such as yogurt, cheese, natto, and miso, short-chain fatty acids are produced in the intestines, which improve the intestinal environment and improve immunity. is.

This combination of probiotics, which deliver good bacteria, and prebiotics, which nurture good bacteria, helps maintain the intestinal environment.

Effective intake time

It is better to take it after a meal rather than on an empty stomach. This is because when you are fasting, your stomach produces a lot of acid, which can easily kill lactic acid bacteria and bifidobacteria. It is most effective if taken after a meal, when stomach acid has calmed down.

Start your intestinal activity by incorporating the high-performance prebiotic “Kestose”

You can start using Kestose at any time.

When it comes to sports, it's hard to get excited about it because it depends on the equipment, the weather, etc. Continuous efforts are required to increase immunity and improve your constitution through intestinal activity. If I can't keep going halfway through and quit, I feel like I'll be mentally depressed.

If you use Kestose for intestinal activity, you can start your intestinal activity by simply adding Kestose to your regular meals. There is no need to measure portions as the recommended daily intake of 3g is individually wrapped. Just mix it into drinks or yogurt for your daily meals or snacks.


If you are concerned about the following lifestyle rhythms or small things that don't warrant a trip to the hospital, I highly recommend trying a bowel exercise.

・Irregular lifestyle and meals
・Pale complexion ・Unstable skin condition ・Unstable stomach condition such as constipation or diarrhea ・Smelly farts ・Easily tired ・Easy to gain weight


Of course, if you are feeling unwell, there is nothing to worry about and you are healthy! Even if you say so, let's start cultivating the good bacteria that decreases with age.


Although the distribution volume is still small and it is not available at supermarkets or convenience stores, you can purchase it immediately from the Nakaya Shoten online shop . We also have great value regular purchase courses, so please try them out.
