Are food Instagrammers really to blame for food waste?

"86% of us admit buying ingredients for one specific recipe, knowing we will struggle to use it elsewhere," according to the report for Sainsbury's.

It suggests under-35s are especially likely to experiment.

Which may be because they're inspired by Instagram to buy ingredients they will never use again. Za'atar anyone?

But can you really blame social media for the UK's food waste problem?
