Reporting from The Conversation says grocery shoppers are influenced by subtle cues that can create a sense of “perceived scarcity,” which in turn encourages people to buy more food than they need. The outlet links these psychological signals to common purchasing behaviors, such as reacting to limited availability or promotional messaging that suggests products may soon run out. To counter this effect and help reduce food waste, the article outlines practical steps shoppers can take. It recommends planning purchases more deliberately rather than responding to in-store cues, using a list or similar method to guide what is actually needed. It also points to paying attention to what is already at home before buying new items, so shoppers avoid duplicating supplies. The piece additionally emphasizes using dates and storage knowledge to make better use of food once purchased, rather than discarding items prematurely. Overall, the guidance focuses on reducing over-buying driven by perception and improving how shoppers plan, store, and use food to limit waste.
