I might add, there's sauerkraut and then there's pickled cabbage labeled as sauerkraut. The pickled cabbage is shredded like sauerkraut and then pickled with vinegar. Kosher sauerkraut is salted cabbage, fermented with lactic acid bacteria, usually in its own juices. The ingredient list is a guide, salt will be probably the 2nd thing listed behind cabbage (though there's not too much).
The kosher stuff is what will provide the most benefits. And as an added benefit, tastes MUCH better.
