What are probiotics?
Probiotics are good bacteria that are found in our digestive system, what few people know is that they have more functions than just regulating digestion.
Here are 6 facts about probiotics that will surprise you.
1.- Our intestine is home to about 100 billion bacteria called intestinal microbiota. They can weigh up to 2 kg!
2.- 70% of our immune system is located in the intestine. Probiotic bacteria protect the intestine against pathogenic (bad) microorganisms and train our immune cells.
3.- Bacteria produce 10% of the nutrients used by the body. In particular, vitamin B12, vitamin K and healthy fatty acids. The rest of the nutrients we take from food we consume.
4.- Babies are colonized for the first time by their mother's vaginal flora during birth. It is likely that a baby born by c-section is more prone to diseases because it does not receive the first defenses of its mother.

5.- Do you find yourself in a bad mood, tired or depressed?. Maybe you should blame your intestinal bacteria. 95% of serotonin, the happiness hormone, is produced in your intestines.
If the microbiota is altered, the intestinal wall will become inflamed and generate disturbances in the production of serotonin. This alteration may be related to irritable bowel syndrome, which may explain that anxiety or a high level of stress causing digestive discomfort.
6.- The intestinal microbiota can affect sleep, and vice versa.
Lack of sleep and stress can alter the microbiota, and the microbiota can alter sleep. There is evidence that the use of probiotics may improve sleep quality.
