Why are there very few, if any, fruit flavored skim yoghurts listed as Kosher?
A. Yoghurts can contain any number of non-Kosher ingredients such as setting agents (possibly gelatin), starters, lactose and/or various other milk based powders (possibly from non-kosher cheese whey) and flavors containing unacceptable base ingredients. Unfortunately, even after much investigation, we have been unable to find many types of yoghurt which are free of the above problems.
