A global food shock is on the way because of the ongoing war in Iran. Your food bill is expected to rise significantly.

The conflict is showing just how fragile our food system is, as spikes in fuel, fertiliser and pesticide prices begin to have knock-on effects around the world. With food availability in jeopardy, should we be stocking supplies at home?
