https://books.google.com/ngrams/graph?content=world+hunger%2... is a much more readable and accurate graph.
Note how both are ~equivalent for a majority of the time, barring 1943 - 1951 (slight edge for food security) and 1960-1970 (larger lead for 'world hunger'). At 1970, food insecurity takes and maintains control.
This is likely because it - as discussed in the rest of the thread - encompasses more, and is a more useful term for scholarly discussion.
Sounds like this term became popular in the 1970s. That was a while ago :)
