Do you think people who drink pasteurized milk don't have bacteria?

Of course not, I'm just trying to explain why someone would take on the risks of non-pasteurized or blanched foods.

However, even gut bacteria isn't a true/false question. It's a spectrum with a range of possible values. Someone with low counts of good bacteria would be instructed by their doctors to find fermented foods like yogurt or sauerkraut to consume.
