A grocery cart with various food items inside.

Do you toss out food each week, even if you follow a grocery list? If so, you’re not alone: In the U.S., food waste is estimated at between 30% to 40% of the entire food supply. Smarter shopping at the grocery store isn’t only about saving money, then, but also reducing this astronomical figure.

So, if you find yourself buying food that goes bad before you can eat it, reduce food waste with these tips on how to shop and cook smarter.

Avoid perishable food

Don’t buy too much perishable food unless you know you’ll eat it. If a favorite fresh food item goes on sale, like ground beef or mangoes, plan to freeze what you can’t eat. Buy freezer bags (freezer-burnt food will only be tossed out, too) and wash and slice your produce before freezing it. Keep meat in its original packaging and place it in a freezer bag for an extra layer of insulation. Write the date you froze the food on the outside of each bag. Most frozen foods are only good for 6 to 12 months, so don’t stock up on three years’ worth of any ingredient.

Buy frozen

Not only should you consider freezing fresh foods, but you should think about simply buying frozen foods to begin with. They typically save time on meal prep — think packs of frozen, pre-cut veggies for a stir fry — which can be a big reason fruits and vegetables get thrown away.

Prepackaged frozen foods can get freezer burn too, so don’t stock up on more than you’ll consume in, again, 6 to 12 months.

Plan meals

Meal planning is beneficial for many reasons. It can help you enjoy food variety and cut down on grocery expenses. And it can also help you avoid throwing food away.

So, when planning meals, take note of a recipe’s serving size (some recipes are designed to feed two, but others will feed six or more). Design your meals around the right number of servings and only buy enough ingredients to meet those servings.

Swap or donate meals

If you plan your meals and still find you have too much food leftover, consider planning meal swaps with neighbors or friends. This can cut down on your own cooking time and reduce the food you’re throwing away.

You can also find a neighbor or two who may have trouble preparing their own meals and help ease their burden by giving them servings of your meals. This cuts down on food waste while helping someone else.

Shopping smart

Sometimes sales are irresistible, but if you end up buying more to save more … and then throw that food away … you’ve only lost money in the end.
