That makes sense to me. I like to cook and make my own yogurt using organic whole milk (Grassmilk from Organic Valley). I typically let my yogurt- maker run for 24 hours instead of the typical 8 hours. That increases the amount of probiotics and reduces the amount of lactose. It is a bit of work, but I would not go back to commercial yogurt. Much healthier and much tastier with whole milk (fat).
