More than a third of farmed fruit and vegetables never reaches supermarket shelves because it is misshapen or the wrong size, according to new research. A University of Edinburgh study found more than 50 million tonnes of fruit and vegetables grown across Europe were discarded each year. This was in part because they did not meet consumers' expectations of how they should look. The study was published in the Journal of Cleaner Production. It examined food loss and waste within the European Economic Area and examined how much food was discarded each year before it reached the point of being sold.
