Recipes using leftovers, tips about what sell-by and best-by dates really mean and examples of what the retailer does to minimise the problem are a good start. But the most important job to be done, along with optimising the supermarket planning and logistics system is to change people's expectations.
We're used, in these instant gratification days, to being able to get anything we want, at almost any time of day. That will have to change. And there is some interesting data to show that it may be amongst the young people that the biggest change is needed. Tegut commissioned a survey that asked, amongst other things, what people do with food that's past the sell-by date. Do they look at it to see if it's still usable, or automatically chuck it away?
Overall, 17% automatically chuck it out, but this figure was only 13% amongst the 50+ group and 22% amongst 14-29s.
Maybe this is one area where the younger generation can't blame the older ones for having messed up the world.
