GI-MAP and similar commercial stool panels

Don't buy the GI-MAP. Finding a microbe's DNA in you isn't a diagnosis.

Skip the gut test. One stool sent to seven labs comes back as seven different men.

Take it alongside anti-inflammatories, and drop it when the pills stop.

Don't buy a leaky gut panel. The zonulin test measures other proteins.

Buy sauerkraut from the fridge or don't bother. The shelf jar is cooked dead.

Kimchi

Eat kimchi because it's good food. Don't count it as a cholesterol treatment.

Natto

Eat natto if you like it. Skip the nattokinase pills sold off its back.

Yogurt

Buy the plain tub. The probiotic one costs more and does nothing extra.
