In fermented foods microbes convert some of the food substrate into microbial protein. We found that in some fermented foods up to 10% of the total protein is microbial and that some of these microbial proteins have functions that might explain some of the beneficial effects of fermented foods.
Assessing the diversity and functional profile of the “microbial proteome” in fermented foods
Fermented foods are staples in diets worldwide and are known for their health benefits. Microorganisms are the key to fermented food production as they convert raw substrates into digestible, nutritio...

I don't think the average person is going to learn much by accessing a paywalled scientific paper.
But the current system keeps out journalists, science communicators, policy researchers, and fact checkers from reading into a topic as well.

In general I think it's hard to combat scientific misinformation when some of the best research is locked behind an academic paywall, while lots of nonsense gets published free for everyone to read in predatory journals.
