Today I will talk to you about probiotics
.
.
In the last survey, we found that many people cannot distinguish between probiotics and lactic acid bacteria
.
In fact, apart from this, everyone still has many misunderstandings about probiotics, such as are prebiotics probiotics? Does more live bacteria mean better results?

In fact, apart from this, everyone still has many misunderstandings about probiotics, such as are prebiotics probiotics? Does more live bacteria mean better results?
Today, I will talk to you about the ten most confusing questions about probiotics
.
.
1.
Probiotics = lactic acid bacteria?
Probiotics = lactic acid bacteria?
Probiotics refer to a type of live microorganisms, which can exert beneficial effects on human health when ingested in sufficient amounts, such as regulating intestinal flora, promoting nutrient absorption, and regulating immunity [1-3]
.
.
Lactic acid bacteria generally refers to the general name of bacteria that can ferment sugar and mainly produce lactic acid.
It is not a strict microbial classification name
.
Probiotics focus on health, while lactic acid bacteria focus on lactic acid production
.

.
Probiotics focus on health, while lactic acid bacteria focus on lactic acid production
.
Probiotics and lactic acid bacteria cannot be simply equated
.
.
Probiotics contain many strains, most of which are Bifidobacterium and Lactobacillus in lactic acid bacteria, such as Lactobacillus acidophilus, Bifidobacterium animalis (Bifidobacterium lactis), Lactobacillus rhamnosus, Bifidobacterium breve, long Bifidobacterium bifidum, Lactobacillus plantarum, Lactobacillus casei, Bifidobacterium, Lactobacillus paracasei, Lactobacillus reuteri and so on
.
.
Not all lactic acid bacteria are probiotics, and some lactic acid bacteria may even be harmful to the human body
.
Only specific strains of lactic acid bacteria whose health effects have been scientifically verified can be called probiotics

In addition, probiotic lactic acid bacteria does not necessarily have to belong to, has some health benefits of yeast and Bacillus probiotic may also be, for example, Powell's yeast, Bacillus coagulans and so on

Prebiotics = probiotics?
Prebiotics = probiotics?
In recent years, prebiotics have also been very popular, and many people often equate it with probiotics
.
Actually, prebiotics are not probiotics
.
.
Actually, prebiotics are not probiotics
.
Prebiotics are substances that can be selectively used by intestinal microbes and produce certain health functions [3-4]
.
You can understand that prebiotics are a kind of food for probiotics
.
Common prebiotics include fructooligosaccharides, isomalt oligosaccharides, inulin, galacto-oligosaccharides, and breast milk oligosaccharides
.

.
Prebiotics cannot be digested by the human body, but they can promote the growth and reproduction of beneficial bacteria in the intestines to promote human health.
Therefore, under normal circumstances, a reasonable combination of probiotics and prebiotics will have a better effect, such as fructooligosaccharides and galactooligosaccharides.
The combination of inulin and bifidobacteria can promote the proliferation and function of bifidobacteria

Dead bacteria are also probiotics?
Dead bacteria are also probiotics?
Some of the probiotic products on the market are live bacteria and some are dead bacteria
.
According to our previous survey, 60% of consumers believe that probiotic products with live bacteria have better health effects
.

.
According to the definition of the World Health Organization, probiotics should be live bacteria, and dead bacteria are not probiotics
.
Therefore, if you see a product that says "sterilized" or "inactivated" on the label, it means that the product does not contain live bacteria and is not a probiotic product
.

.
Moreover, most studies have shown that the effect of live probiotic bacteria is better than the corresponding dead bacteria
.
Therefore, if you can, you should try to choose products with live bacteria

However, the metabolites and cellular components of dead bacteria may have certain health benefits.
For example, polysaccharides, short-chain fatty acids and other substances are beneficial to health, and this needs to be further studied

Probiotics are harmful to the human body?
Probiotics are harmful to the human body?
Many people worry that probiotics are harmful, and some media have also reported that probiotics are harmful
.
Only after the approval of relevant departments can be marketed, the approved probiotics are safe for most people, and there is no evidence that long-term consumption of probiotics has adverse effects

The effects of all probiotics are the same?
The effects of all probiotics are the same?
When it comes to probiotics, many people feel that their effects are the same

In fact, different bacteria have different functions

The more viable bacteria, the better the probiotic effect?
The more viable bacteria, the better the probiotic effect?
When buying probiotic products on the market now, it is often seen that some products contain 1 billion live bacteria and some contain 10 billion live bacteria
.
Some people think that the more viable a product, the better the effect
.
.
Some people think that the more viable a product, the better the effect
.
In fact, this is not much
.
.
The effect of probiotics is related to the dosage, and only enough probiotics can be taken in order to achieve the corresponding effect
.
But when it reaches a sufficient dose, continue to increase the dose, its health effects will not be better

Moreover, different strains have different dosages for their health effects

Just comparing the quantity, not looking at the strains, is actually of little significance

The more types of strains, the better the effect?
The more types of strains, the better the effect?
Now on the market, some probiotic products say that they have several types of bacteria.
It seems that the more types of bacteria, the better the effect
.
It seems that the more types of bacteria, the better the effect
.
But this is not the case
.
.
Although some studies believe that different strains may have synergistic effects, not all strain combinations have this effect
.
Therefore, the number of strains contained in a probiotic product is not necessarily related to its effect, and it is not that the more strains, the better the effect

Frequent consumption of probiotics will cause dependence?
Frequent consumption of probiotics will cause dependence?
Some people worry that if I often eat probiotics, will it become dependent and I will have to eat it every day in the future?
This worry is unfounded
.
.
Because the probiotic strains that have been scientifically evaluated are safe for normal people, they will not cause the human body to become dependent at all

Chinese probiotics are more suitable for Chinese people?
Chinese probiotics are more suitable for Chinese people?
In recent years, some self-developed probiotics have also begun to enter our lives.
Many people say that China’s self-developed probiotics are more suitable for Chinese people

.
In fact, this statement is unreasonable, and the effects of probiotics will not differ depending on the race
.
.
The main factors affecting the human intestinal flora are diet and environment.
There will be certain differences in the composition of the intestinal flora of people around the world, but the role of the intestinal flora in human metabolism will not be due to factors such as population race, age, etc.
There is a significant difference, and there is no obvious difference in the effects of probiotics due to different races

Of course, we also encourage Chinese companies to improve their production and R&D levels and develop bacterial strains with independent intellectual property rights, but which one to choose depends on their own preferences and needs

Can probiotics cure all diseases?
Can probiotics cure all diseases?
At present, most scientists believe that probiotics can regulate the intestinal flora and promote the digestion, absorption and metabolism of nutrients in the intestines, which are beneficial to human health

As for other effects, probiotics currently have some clinical applications.
They are good in regulating immunity, preventing and reducing the risk of diarrhea in children and shortening the duration, improving constipation, reducing symptoms of enteritis, improving allergies and weight control, etc.
