The "good bugs" that are used to ferment the milk. Yes they are probiotics in a sense, but more good bacteria, or starter cultures, used in so many foods, like sauerkraut, salami, yogart, cheese, and many other foods. Possibly the oldest form of preservation is fermentation.

Sorry all -- a glitch in our system caused the multiple postings. @geofreejames did ask just once.

Please just ask once. The answers come from Food52.com site members who are likely busy on this day. Who says it is healthier? Compare the fat content. The one with the least fat is the healthier one.
