Throughout Europe there is no universal approach to dietary management of galactosaemia. Other than lactose, there is discrepancy concerning the inclusion or exclusion of potential sources of galactose such as galactosides (peas, beans, and lentils), galactose storage organs or the so-called nucleoproteins (offal) and free and bound galactose found in fruit and vegetables. With the advent of the Internet, patients and parents from all over Europe have more international contact with each other. Different dietary approaches cause confusion, uncertainty and may lead to misconceptions. Therefore, it is important to identify and document the scale of the discrepancy in advice across Europe.
