Food for thought

You report (8 October) that in Scotland we waste one fifth of the food and drink we buy annually, amounting to £1 billion, but the figures don’t add up.

The total of the categories you list – drinks, fruit and vegetables, bread, meat and fish – comes to only £530 million. Where does the other £470m come from?

Furthermore, if we spend only £5bn per year, or a little less than £20 per person per week, how can “cash-strapped shoppers (save) £22 per week by shopping at Aldi” (your report, same day)?

It would be interesting to know who carried out this research (your story doesn’t say), and how they account for these curious figures.
