What kind of probiotics are good?

Looking at the supermarket shelves, we can see all kinds of yogurts. There are more than 20 kinds of lactic acid bacteria added to the yogurt ingredients, and the health functions emphasized are also varied, such as enhancing nutrient absorption, regulating the stomach and intestines, and increasing the beneficial bacteria in the intestines, etc. Some also indicate health and beauty effects. What kind of probiotics are good for people's health? What are the specific effects?

White-collar workers who have some knowledge of nutrition drink yogurt on a daily basis. Why? Because probiotics are added to yogurt. Probiotics play an important role in the intestinal ecosystem. For example, they are beneficial to the metabolism of vitamins, have antibacterial activity, have a certain effect on immune function, and can accelerate intestinal transmission.

What kind of probiotics are good for people's health? What kind of effects do they have? What are the selection criteria for yogurt that can be added with probiotics?

Professor Chen Yourong, executive director of the Lactic Acid Bacteria Branch of the Chinese Society of Food Science and Technology, said that not all yogurt products contain sufficient numbers of active probiotics, and not all probiotics have been proven to promote gastrointestinal health. Good probiotic strains, bacterial survival, and sufficient numbers of active bacteria should be the three major standards for high-quality probiotic yogurt. A good strain should be safe, active, and have clinically proven efficacy. The survival of bacteria is the key to ensuring that probiotics can resist gastric acid and bile and eventually reach the intestines. As for the number of active bacteria, the foreign standard is 107, and the domestic requirement is 106. It should be emphasized that not every strain of probiotics can exert all health benefits.

It is worth mentioning that foreign probiotic strains are not necessarily suitable for the physiological characteristics of our Chinese population. From the perspectives of physiology, human microecology, and reproductive evolution, humans and probiotics must adapt to each other in terms of species, flora, and environment. Therefore, when choosing probiotics, you must choose according to your physical condition. It does not mean that one is best and the other is bad.
