Alpha13 saidI saw an article saying that our gut was smarter than our brain ( the bacteria brain cells outnumbered our central brain). Im starting to think that microbes are the dominate species on the planet.
We need to take probiotics because our "city" water has chemicals in it to specifically kill bacteria, and so do drugs, high acid diets etc.
I`d heard the human body has ten times as many foreign microorganisms within it than our own cells! We are mostly not human!
Microbes probably are the dominant form of life on Earth, if you measure it in terms of species numbers, biomass, or absolute numbers. I`d go as far as saying they are in the universe! They`re hardiest, reproduce fastest, and evolve and adapt fastest. They were the first forms of life here, and had the place to themselves for three billion years before multi-cellular life came along. They keep the place ticking over during Earth`s periodic crises/mass extinctions, etc. And they`ll last the longest into the far future.
The vast majority live completely separate from us, for example, in oxygenless environments. The remaining species can be pathogenic, or salugenic(positively good for our health). These may be part of the post-antibiotic future as they actively combat the pathogens.
From what I`ve read these probiotic supplements are mostly a waste of time for someone in good general health and eating a balanced/healthy diet.
Some who have specific gastro-intestinal conditions, or who`ve had powerful doses of antibiotics after surgery, etc. may benefit from them. But generally the microbes down there are quite capable of looking after themselves(and us!)
