[Diet and health of deprived population in developed countries : What is the link.].

The diet is often unbalanced and deficient in poverty situations and deprived populations are becoming larger and larger in developed countries. Negative effects on the health of poor populations are expected in the short or long term. The link between diet and health is well investigated in many epidemiological studies ; however they seldom analyse the link between infectious diseases and diet in western countries and rarely include poverty indicators that could help to provide more information about the situation among poor populations.
