The Harmful Effects of Fermented Foods ?

Hey,

Why are fermented food like yogurt considered healthy if lactic bacteria produce waste product.

Why should we eat bacteria wast product ?

I'm just questionning those stuff.

What this site is saying makes sens ( even thought I don't agree with the rest of the site) but what are your thought about it ?

What about lactic acid for instance, does it make stiff muscles ?

And ammonia ?

"In industry, lactic acid fermentation is performed by Lactobacillus bacteria, among others. These bacteria can operate in the mouth; the acid they produce is responsible for the tooth decay known as caries.[2][3][4][5]"

Thank you for your inputs.
