On the grounds of collected information from trials aforesaid, as well as from other publications concerning phosphorus and calcium nutritional recommendations , the updating of those recommendations for Polish are proposed. Changes refer mainly to increased calcium and phosphorus intake among adolescents of both sexes, aged 10 - 18 years. For adults aged 26 - 50 and 60 and over, the increase of calcium intake and the reduction of phosphorus intake is proposed. The group of menopausal women is separated in the publication.

It is stressed in the paper that increased calcium intake can prevent osteoporosis regardless of age.
