Digesting the Cost of Food

We look at food prices, as the return of economic activity and extreme weather bring with them a rise in the cost of grain. Corn and wheat prices are edging up again, so are we in for a repeat of the hike seen in recent years? Higher prices always bring with them winners and losers. We talk to consumers in Mexico and Kenya, a farmer in Britain and the author of a report on food prices which says that a rise in the cost of food is both inevitable and necessary.
