Not sure I follow - is there a suggestion that you can only eat 'foods enriched with bacteria like probiotic yogurt'? I would think the less questionable benefits of eating yogurt would be calcium and protein, at the very least. This study didn't try to feed any sort of special 'probiotic' foods to the mice.

Yogurt is a great, but greatly overlooked source of many other nutrients such as iodine.
