Yes, it's that easy. And prices of commodity food staples only cause unrest in very poor nations where food inputs constitute a large % of their income.

Wheat costs about $200/ton and peaked around $450/ton during the arab spring period. A ton of wheat (with a few supplements) is enough to for 500g/day for 5 people for a year if half your calories come from wheat. Even at $500/ton, that's about $100/yr/person for the wheat itself. Wholesale raw foods are quite cheap from the perspective of someone in a rich nation. Can be quite expensive for the very poor. The solution is to help people in poor nations industrialize so that they are less poor.
