Indeed, out of everyone employed across the fragmented U.S. food system, consumers may have the least professional training in handling and preparing food. Adding to the mayhem, firms may not always want to help consumers get the most out of food purchases. That could reduce their sales – and if food that’s been stored longer degrades and becomes less appetizing or safe, producers’ reputations could suffer.

To ensure global food security and sustainable food practices in an ever-growing world, we need to reexamine our food systems and take regional resources, such as land and water availability, as well as local economies and culture into account.  To start, the United States and other developed countries must encourage food companies to produce more sustainable food, including more plant-based options, and educate consumers and retailers about healthy and sustainable diets.

The U.S. Environmental Protection Agency has some best practices for families to save money, help those who don’t have enough to eat, and conserve resources for future generations. By making a list of weekly meals and necessary ingredients, shoppers will buy less than they would otherwise and keep things fresh, with less waste. Also, checking the pantry and refrigerator before a grocery shopping trip can prevent buying duplicates of things you already have.
