A team of researchers at the University of São Paulo in Brazil analysed the diagnosis, and genetic and clinical factors of lactose intolerance.
Their conclusion is that the symptoms of lactose intolerance may have been exaggerated and that persons with lactase non-persistence can tolerate up to 12 g of lactose. Consequently, they need not limit their consumption of dairy products to lactose-free milk and/or fermented milk, which could be beneficial to their bone mass density.
