Certain yogurts contain probiotics, which are beneficial bacteria that have been shown to help prevent or treat various types of diarrhea. Do all yogurts contain probiotics? Bacteria are naturally found in all fermented milk products, including yogurt. To make yogurt, specific bacterial cultures are added to milk to help convert its sugars into lactic acid. This fermentation process is what sets the yogurt. To be considered a probiotic, bacteria need to be alive and able to provide health benefits. The starter bacteria cultures used to make yogurt aren’t considered probiotics, per se, as they often don’t survive digestion and thus don’t confer any therapeutic effects on your body ( 11
