Those are all very bad recommendations. Buttermilk is loaded with cholesterol and saturated fat, kombucha with sugar, and fermented vegetables like kimchi have shown to increase prostate adenocarcinoma. You want to regulate your gut flora with a variety of whole plant-based foods, not quick fixes like pills and a jar of stinky cabbage.

Neither dietary cholesterol nor saturated fat nor sugar are bad in moderation, and that's completely orthogonal to the point of them providing probiotics.

Motor oil could provide probiotics if cultured - wouldn't make it healthy to consume, except in "moderation".

> milk is loaded with cholesterol and saturated fat

Neither of these are bad for you, just don't be obese

> kombucha with sugar

Every bottle of kombucha I have ever seen has at most 16g of non-added sugar from fruits, the same as a banana

> fermented vegetables like kimchi have shown to increase prostate adenocarcinoma

Fake / trash science. More studies say the opposite than agree with this

> Neither of these are bad for you, just don't be obese

Every nutritional authority in the world disagrees.

> Every bottle of kombucha I have ever seen has at most 16g of non-added sugar from fruits, the same as a banana

Right, sugar from a drink and banana are identical, even though only one has fiber. What mental gymnastics!

> Fake / trash science. More studies say the opposite than agree with this

Why didn't you cite them?

> "fermented vegetables like kimchi have shown to increase prostate adenocarcinoma."

Since you did not link to any literature backing up your claim, I want to share this paper[0] as a counterpoint. Kimchi has been found to have active ANTI-cancerous effects, opposite to your claim.

Please change my mind with referenced material.

Do preserved foods increase prostate cancer risk?

Vegetables, but not pickled vegetables, are negatively associated with the risk of breast cancer

Your study was in vitro and given the authors' background and affiliation was most likely made to promote agricultural production.

You are telling me milk kefir is the cause of health issues? I would suggest limiting it to a few spoons a few times per week, then.

How would you make that practical? How long can you keep a bottle of kefir open before it goes bad?

I have half glass of milk with kefir cultures, only, and I keep in the fridge. I use it also ad sauce, because the cultures get big and it gets concentrated and strong.
