If imports are "people's food", that would imply a food shortage in that country. The Doha Round is supposed to be about such countries' economic progress through access to Western markets, yet the result in your scenario would be (a) even less local produce for the locals just because of exports, (b) the death of most of the local production as foreign imports get cheaper, (c) as a direct but delayed consequence of this collapse, a lot of people would not be able to buy even the cheaper Western produce, resulting in an artifical famine like in Niger earlier this year.

(Actually, I do not think even the food part of it is 'people's food' - to a large part, more likely the local elites' and the local small middle classes' food.)
