Many environmental influences associated with unhygienic living have been considered important in the development of rheumatic fever. Whether such living conditions may condition the host to rheumatic fever is unknown; however, it has been shown1 that these factors increase susceptibility to infections of the respiratory tract, predispose to complications and promote the spread of hemolytic streptococci.

To determine whether this conditioning factor may be a faulty dietary, we have conducted nutritional surveys in the city of New York and tested the effect of a reenforced diet on rheumatic children at the Pelham Home. The present paper includes data from these studies.
This study is based on the diet records of three groups
