Yogurt is made by adding "good" bacterial cultures to milk, which change the milk's lactose (sugar) into lactic acid and give yogurt its tart taste and pudding like texture

The body's digestive tract needs good bacteria to check the growth of harmful bacteria, support the immune system, ward off imbalances in yeast levels and enhance digestive health

A study of very elderly people found a lower incidence of death among those who ate yogurt at least three times a week

To get the benefits, buy yogurt that has "live active cultures"
