Quick Tips
Check your supplies before shopping Use up the food you have.
Stick to a grocery list to avoid impulsive buying. Don't shop when you're hungry.
Proactively freeze bread, vegetables, dairy, and meat before they go bad if you buy in bulk and don't go through the food fast enough.
Buy a variety of food. Some foods last longer than others. Eat leafy greens and mushrooms first, but keep root vegetables and squash in the pantry to eat later.
Purchase food that is in season for the greatest value, least embedded food miles, and longevity of shelf life. Further, consider purchasing from local farmers and markets first when planning your shopping; that ensures seasonality, freshness, minimal packaging, and maximum impact on the local economy.
