Nutrition and bone health is tale of two nutrients: calcium and vitamin D. Studies carried out in the last century brought to light several complex and intricate interactions between these two seemingly simple nutrients and bone with several twists and turns. The new century has brought answers to some questions but raised many more issues. The Nutrition Foundation of India (NFI) and Centre for Research in Nutrition Support Systems (CRNSS) organized a two day Symposium on "Nutrition and Bone Health" on 31st July and 1st August 2007 in Delhi to discuss physiology and molecular biology of vitamin D and calcium, prevalence of calcium and vitamin D deficiencies in different ages and physiological groups, clinical consequences of vitamin D deficiency in infancy and childhood, prevalence of nutrition related bone diseases in various age groups in India and abroad.

Some papers from the meet are published in this issue of the IJMR. Calcium and vitamin D requirements
