We started this Daily with news about multinationals trying to reduce food waste, we end it with news about what you as a consumer could do to reduce food waste at home. Victoria Ligon, from the University of Arizona, has been looking into this question. She tracked shopping and food preparation patterns, interviewed participants, and followed food diaries. She found out that the best way to reduce food waste is by shopping for only a day’s worth of ingredients at a time. Instead, many shoppers now try to buy foods for the whole week, shopping for bulk quantities of high-quality ingredients in warehouse-style stores. All those things don’t always get eaten, because the week doesn’t always turn out as planned. Ligon’s advice: limit your planning to the next several meals, in order to accommodate unforeseen schedule changes.
