Most of the health benefits from sauerkraut come from the good bacteria and active and live probiotics that non pasteurized or homemade sauerkraut contains.
So that makes pasteurized sauerkraut less healthy for you than non pasteurized sauerkraut.
The pasteurization process of the sauerkraut kills the good bacteria and live probiotics so you don't get those good health benefits from the sauerkraut like you would with homemade sauerkraut or non pasteurized sauerkraut.
Still yes pasteurized sauerkraut is still good and healthy for you and you still get some health benefits even when eating pasteurized sauerkraut.
For pregnant woman they should always eat the pasteurized kind of sauerkraut to prevent possibly harming the baby or pregnancy.
But if you're not pregnant then eating non pasteurized sauerkraut is just fine.
