rickets is a disease caused from a critical lack of vitamin d that leads to a lack of calcium and phosphorus and eventually the softening/weakening of the bones. since the absorption of vitamin d is dependent on sunshine rickets is more common in countries that receive little sunshine and where the diet may be deficient in this essential vitamin. in the u. s. and other modern countries where many of our foods and milk is vitamin d-fortified rickets is rare.
