Probiotics are bacteria and fungi that confer a health benefit on the host. Probiotics in our bodies outweigh our brains.
Adam Rifkin stashed this in Microbiome
Our microbiome is an organ replete with probiotic bacteria:
The typically human brain weights about 3 pounds, and a healthy human body will have over 3.5 pounds of probiotic bacteria and organisms (according to Casey Adams Ph.D. The fact that our heart weights only 0.7 pounds, our liver weights about 4 pounds, makes our probiotic bacteria one of the largest organs in our body.
There are ten times more probiotics than cells in our bodies:
In a healthy person, there are more than 100-300 Trillion probiotic bacteria and yeast, compared to only 10 trillion cells in our body. According to Mary Ellen Sanders, if the bacteria in our body were laid end to end, they would encircle the globe 2.5 times.
400 strains of probiotics live in our bodies:
According to numerous research studies, there are well over 400 probiotic strains resident in our bodies. Some of these probiotics are permanent residents, and others are transient. Interestingly, only 20 strains account for 75% of the mass of bacteria that live in our bodies.
Numerous scientists also argue that the combined DNA of our probiotic residents are more important to our survival than our own DNA.
