Some Varieties May Benefit Digestive HealthSome types of yogurt contain live bacteria, or probiotics, that were either a part of the starter culture or added after pasteurization.These may benefit digestive health when consumed (17Trusted Source).Unfortunately, many yogurts have been pasteurized, which is a heat treatment that kills the beneficial bacteria they contain.To ensure your yogurt contains effective probiotics, look for one that contains live, active cultures, which should be listed on the label.Some types of probiotics found in yogurt, such as Bifidobacteria and Lactobacillus, have been shown to lessen the uncomfortable symptoms of irritable bowel syndrome (IBS), which is a common disorder that affects the colon (18Trusted Source, 19Trusted Source, 20Trusted Source, 21Trusted Source).One study had IBS patients regularly consume fermented milk or yogurt that contained Bifidobacteria. After only three weeks, they reported improvements in bloating and stool frequency — effects seen after six weeks, as well (21Trusted Source).Another study found that yogurt with Bifidobacteria improved digestive symptoms and health-related quality of life among women who did not have a diagnosed digestive condition (22Trusted Source).Furthermore, several studies have found that probiotics may protect against antibiotic-associated diarrhea, as well as constipation (23Trusted Source, 24Trusted Source, 25Trusted Source, 26Trusted Source, 27Trusted Source, 28).SUMMARY:Some types of yogurt contain probiotics, which may boost digestive health by reducing the symptoms of common gastrointestinal disorders, such as bloating, diarrhea and constipation.
