Probiotics refer to a kind of microorganisms that can reproduce in human body and are beneficial to human body. They mainly exist in human intestines and are all non-pathogenic microbial strains. Meanwhile, they have the following five functions and effects:

1. Maintaining intestinal health: The intestine is one of the most important digestive organs in human body, and its function has an important impact on human health. Probiotics can help digest food, promote the absorption of nutrients in food, improve the intestinal environment, reduce the reproduction of pathogenic bacteria and protect intestinal health.

2. Improve immunity: the intestine is an important part of the human immune system. Proper intake of probiotics can increase the number of beneficial bacteria in the intestine, improve intestinal immunity and enhance the ability of human body to resist diseases such as viruses and bacteria.

3. Promote calcium absorption: Probiotics can help people absorb calcium and inhibit the formation of calcium particles in the intestine, thus preventing osteoporosis.

In short, proper intake of probiotics can bring great benefits to human health. We can increase the number of probiotics in the body by eating probiotic products, such as yogurt and fermented food. At the same time, we can also increase the survival of probiotics in the intestine by eating more high-fiber foods, vegetables, fruits and other foods that can promote intestinal health.
