David Biderman was quoted in the FoodNavigator-USA.com article, “Lifeway to 'vigorously defend' lawsuit, ‘Our kefir is 99% lactose free’,“ regarding a complaint filed against Lifeway Foods claiming it falsely advertised its fermented dairy products as '99% lactose free' when they allegedly contained almost 4% lactose: "David Biderman (who is not involved in this case), told FoodNavigator-USA that provided it has solid data, Lifeway has a good chance of prevailing: "If Lifeway has tests for lactose that substantiate its claims, it should be able to prevail unless the plaintiff has very strong test results contradicting that claim. In particular, if the Lifeway tests were conducted pursuant to reference testing methods cited in the FDA regulations, these tests should be given great deference by the court. California courts have scrutinized the validity of plaintiffs challenging label substantiation and will dismiss cases where the plaintiffs' claims of lack of substantiation are not supported by valid scientific evidence."
