BBC journos have a specific editorial style, and no doubt it influenced this headline, but this isn't to "protect food heritage". Food and drink accounts for a quarter of Italy's GDP. It's about money. Italy has a far-right government, which is extremely open to lobbying from that sector, and "heritage" is aligned with their nationalistic stance. Try to look a bit deeper.
Ah yeah the left never takes lobby money. If you want to make a point, try not to make your bias so clear.
