US Secretary of State Condoleezza Rice stated: the "growing Indian and Chinese appetite in contributing to the global food crisis." The source article says these countries dominate food consumption so this isn't entirely incorrect.
Rice believes if people in these countries eat less, there will be more food globally. However, its noted that the increase in bio-fuels has lessened how much food there is for consumption.
Also, India blames the US federal reserve and international market for increasing energy and food prices. One Indian government minister states both India and China have increased food production as a response to growing demand.
