Yogurt is easier to digest than milk

Yogurt is a fermented dairy product made by adding bacterial cultures to milk, which causes the transformation of the milk's sugar, lactose, into lactic acid. This process gives yogurt its refreshingly tart flavor and unique pudding-like texture, a quality that is reflected in its original Turkish name, Yoghurmak, which means "to thicken."

The culturing process makes yogurt more digestible than milk. The live active cultures create lactase, the enzyme lactose-intolerant people lack, and another enzyme contained in some yogurts (beta-galactosidase) also helps improve lactose absorption in lactase-deficient persons. Bacterial enzymes created by the culturing process, partially digest the milk protein casein, making it easier to absorb and less allergenic. In our pediatric practice, we have observed that children who cannot tolerate milk can often eat yogurt without any intestinal upset. While the amount varies among brands of yogurt, in general, yogurt has less lactose than milk. The culturing process has already broken down the milk sugar lactose into glucose and galactose, two sugars that are easily absorbed by lactose-intolerant persons.

The food ranking system qualified yogurt as a very good source of calcium, phosphorus, riboflavin-vitamin B2 and iodine. Yogurt also emerged from our analysis as a good source of vitamin B12, pantothenic acid-vitamin B5, zinc, potassium, protein and molybdenum. These 10 nutrients alone would make yogurt a health-supportive food. But some of the most interesting health information about yogurt comes from a different context-its potential inclusion of live bacteria.
