I thought of a rare and top ingredient in Asia which claimed to be good for your health is 燕窩. Which is literately "the nest of swift" (A kind of bird), and it is made of the swift's saliva.
And it's very expensive, only sold in high-end restaurants. The cheap substitute is a kind of fungus called 木耳, means the ear grown from the wood.
They are vary common in the daily lives here. And when children are sick, parents will buy and make soup using these ingredients as food medicine.
Very common? I thought bird's nest soup (the english name for the first thing you mentioned) was extremely, extremely expensive?
"With regularity", G-Flex. With regularity. It's a hostile enough environment that it makes me have serious doubts about probiotic foods causing a health boost. Plus, all of the bacteria you listed have evolved to survive in such an environment as the human digestive tract, where as the bacteria in probiotic foods have not. I imagine that servery decreases their survival odds compared to e-coli and the like.
Then please, again, explain to me how the typical "good" gut flora end up in your stomach to begin with, if even eating yogurt every day can't accomplish getting any in there.
"All the bacteria I have listed" include several genera of bacteria, and even some fungi. Probiotic products, to my knowledge, tend to use bacteria that are already naturally found in there, and thus would obviously be capable of introduction to the gut.
Simply put: If eating non-fermented food, and other regular behavior, is more than capable of introducing significant live bacteria to your intestines, then how in God's name is regularly eating food specifically
made to contain live cultures
not capable? Yes, a lot of bacteria will probably die in your stomach acid, but it's very trivially provable that enough bacteria from
normal eating habits manage to survive, never mind foods with high amounts of live cultures specifically added.
And speaking of fermented food, we chinese have another second processes food called 豆腐乳, simply a kind of fermented tofu.
Yeah, as well as other fermented soy products common to East Asian nations.
For that matter, soy sauce is fermented.
