10 Tips for Fighting Food Waste – Day 14 of the Zero Waste Challenge

31 Day Zero Waste Challenge

Last Updated on January 23, 2024

Food is too good to waste, and yet one third of food produced for human consumption is wasted or lost globally.

With a staggering 40% of food being wasted in the US alone. Food waste seems like something small, but it adds up to a massive… and I mean MASSIVE impact.

If food waste were a country, it would be the third largest emitter of greenhouse gasses behind China and the US. Today, I challenge you to keep break up with food waste!

10 Tips for Fighting Food Waste - Day 14 of the Zero Waste Challenge from #zerowaste #ecofriendly #gogreen #sustainable #zerowastechallenge #challenge #sustainablelivingchallenge #fightfoodwaste #erasefoodwaste

It’s day fourteen of the zero waste challenge! The beginning of the challenge is focused on simple swaps like bringing your own water bottle and bags to the grocery store.

Now, we’re in the second phase of the challenge. These changes are lifestyle changes like learning to make your own snacks, decluttering your life the zero waste way, and conserving natural resources.

Today we’re talking about another lifestyle change – ending food waste!

the problem:

In America alone we waste 40 percent of our food. That’s absolutely crazy since so many people go hungry.

In fact, according to the Food and Agriculture Organization of the United Nations, 821 million people globally go hungry and are undernourished.

The saddest part about that statement is we have enough food to feed everyone on the planet, but most of it is wasted or lost.

Essentially, food waste is food that reaches its final production stage, is fit for human consumption, but for all kinds of reasons is thrown away.

Like the insane beauty standards our food has to go through to be able to reach store shelves.

Food loss is food that never reaches its final production stage (which means there’s poor management inside the company producing the food).

Obviously, not all food waste is the consumer’s fault (it’s also companies who manage food poorly), but there certainly is a problem with how we (consumers) treat food.

Thankfully, there are so many things we can do to help prevent food waste.

Y’all know how much I hate food waste, let’s taco bout it. 1 in 9 people go to bed on an empty stomach every night. Meanwhile the US wastes 40% of all it’s food from supply to grocery stores to our own kitchens. While we can’t immediately change the supply, we can help control the narrative. Shop from a local farmer. Buy the ugliest produce you can find. Buy the loneliest banana. Don’t buy too much food so it doesn’t go to waste. And, eat your food scraps!! Broccoli stems with some julienned carrots and green apple with a little bit of ginger, soy sauce, lime juice, and rice wine vinegar make for a cool delicious slaw. Perfect for topping my black bean tacos. And, we know Nala is the real MVP when it comes to food waste. Any crumb that hits the floor, she is on it!

the solution:

make a plan:

The first thing is to make a plan. I’m not asking you to sit down and do a huge meal plan: I know that can be a total pain.

I’m just asking you to open up your fridge and your freezer and look at your pantry before you go grocery shopping.

If you open up the fridge and say “hey, I’ve got a tomato, a couple carrots and some broccoli that needs to be eaten”, then you can think of a meal or two for the beginning of the week where you can use those up.

You also know now that you don’t need to buy tomato, carrots or broccoli which prevents you from buying duplicate items.

store it right:

When you’re grocery shopping, think about how you’ll be storing your produce.

Proper storage is key to making fruits and veg last as long as possible! Be sure to check out my plastic-free storage guide and the video as well.

ignore those dates:

You can pretty much ignore the “best by, sell by and use by” expiration dates. It’s best to always do a taste test.

Here’s what those expiration labels really mean:

  • Sell by: Tells the store how long to display the product for sale. Not a safety date.

  • Use by: Last date recommended for use when the product is at peak quality. Not a safety date except when used on infant formula.

  • Best by: Indicates when product will be of best flavor or quality. Not a safety date.

As you can see, these expiration dates aren’t as scary as they look on a product.

Certain food products you don’t even have to worry about the expiration dates – they might last a longer time than you think…. like honey.

Honey from 1,000s of years ago is still perfectly edible. Or, they might not last as long as the expiration date says.

It all depends on how they’re stored, the temperature and a bunch of other factors, so it’s always best to go with a smell and taste test.

Even certain things like sour milk are edible, it’s just not enjoyable to drink a glass of it (but it works great in waffles).

So, think of creative ways you can use some of those items.

save it:

If there’s something on your plate you can’t finish, don’t be shy to ask a family member if they want it instead.

If not, save it for later instead of throwing it away.

The same goes for eating out: If there’s food you can’t finish on your plate, be sure to take it home instead of throwing it away.

I like to bring a reusable container with me when I know I’ll be dining out, just in case I have leftovers.

Get my ultimate guide for storing leftovers without plastic.

Make sure to order or cook with foods you actually like too: While there’s nothing wrong with experimenting, new foods don’t always go over too well (so they’re more likely to get wasted).

Also, whenever produce starts to go bad, or looks sad, consider pickling them.

Making dill pickles, or beet pickles is a great way to salvage vegetables (and you can honestly pickle almost any vegetable including carrots, cauliflower, artichokes, etc.).

use your scraps:

Another great way to reduce food waste is to cook with your scraps.

There are so many parts of a vegetable that often get thrown out but are perfectly edible, like carrot tops and broccoli stems. Carrot tops can become pesto and broccoli stems can become slaw.

Here are a few other ways to cook with scraps:

  • Make zero waste vegetable broth from food scraps.

  • Use herb stems in soups, stews and salads instead of discarding them.

  • Add celery leaves to your next soup for extra flavor.

  • Save pumpkin seeds and roast them later.

  • Cook beet tops into a delicious veggie stir fry.

  • Make salad from herb stems, carrot tops, radish tops and beet tops.

  1. Quiche/frittata is a fairly consistent go-to for me when it comes to veggies that are looking a little withered or I have extras of. I even throw old french fries and tater tots my kids didn’t finish at restaurants into them!
    I store my produce that stays out of the fridge (onions, potatoes, etc) in wire mesh desk file folders I bought from Ikea. I also always snatch up old glass containers with lids from thrift stores (you can also order a replacement lid online!)
    These are great tips and I am loving the challenge! Thank you!

  2. This is something I actually struggle with – food management, especially produce items. And thanks for explaining the expiration date types. I threw away a lot of food just because things were a few days past the ‘expiration’ date, but now I know to rely on my instinct more or use those ‘expired’ foods in other ways.
