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.

> 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.
