According to a recent small study, people with lactose intolerance can enjoy probiotic yoghurt if it is fortified with specific lactase-positive bacteria, namely Lactobacillus acidophilus and Bifidobacterium sp..
It seems that these bacteria increase the ability of people to digest lactose by normalising the gut flora and the production of more lactase and therefore preventing lactose fermentation. The last one normally causes lactose intolerance symptoms such as bloating and flatulence.
So if you are lactose intolerant but want to benefit from the health advantages of yoghurt, just look for a yoghurt that contains lactase-positive bacteria!
