What do you do to introduce beneficial bacteria to your own digestive system?

I don't worry about that because humans normally have many beneficial bacteria in the intestine already. I am also blessed to have been free of any kind of intestinal problems for all of my 64 years, with the exception of an occasional intestinal virus. Safer sources of beneficial bacterial would be some varieties of pasteurized milk, yogurt, or Activia.
