Wheat and obesity

I've been reading on Tu diabetes of a new book that appears to claim that the wheat consumption in the US and their obesity levels are associated. I decided to look out some figures . As I couldn't work out how to post the relutant graphs I've put them here.

I managed to find this graph of wheat consumption in a set of countries
(as the print doesn't show up clearly, they are in order:

China,India ,USA ,Russia ,France,Canada,Germany,Turkey,Pakistan ,Australia,Ukraine, UK,Iran ,Argentina ,Kazakhstan,Poland ,Egypt ,Italy,Romania ,Uzbekistan .

I used data from the WHO to show the obesity levels in those countries


I really can't see any correlation at all.
