Other Disorders of the Skeletal System - Diet and bone disorders

A proper diet is necessary to maintain the health of the skeletal system. The body's retention of the bone-building minerals, phosphorus and calcium, depends on vitamin D, which is manufactured in the human skin through the action of the sun's ultraviolet radiation.


An insufficient supply of vitamin D and a lack of exposure to sunlight leads to a vitamin deficiency disease known as rickets . It can occur in infants and small children who live in northern latitudes and thus are not exposed to sufficient sunlight to permit their body to manufacture vitamin D. Rickets slows growth and causes bent and distorted bones and bandy legs. Symptoms first appear between the age of six months and the end of the first year. If rickets is recognized in time, it can be cured by a diet containing adequate vitamin D and by exposure to sunlight. If the disease is unchecked, the bones may develop permanent curves.
