The latest data from the just-food international basket, published today, covers the second quarter of 2013.

The basket is a group of 17 items from tuna to milk that highlights the difference in price between national brands and own label in seven international markets.

Amid the worst economic conditions for a generation, shoppers are becoming more promiscuous in their behaviour and the data will prove valuable to brand manufacturers, own-label suppliers and retailers alike.

The data is compiled exclusively for just-food by IRI. Tim Eales, strategic insight director at IRI, reflects on the latest findings here.
