The Case for Frozen Vegetables

How to incorporate more vegetables into your diet without extra work

It’s Tuesday night. You have a hungry family, and you’re a bad parent if the dinner you’re about to serve doesn’t have vegetables in it. You must choose: your sanity or your family’s health and longevity.

To chop or not to chop?

But wait. There must be an easier way.

You remember you saved a bag of frozen mixed veggies for a moment just like this. But they’re frozen, so they can’t actually be healthy, right? You’re basically still a bad parent, but you technically get a pass, right?

Wrong. No pass needed. You get an automatic promotion to Super Parent. You don’t get carted off to bad parent prison. You may pass Go. You may collect $200. You win.

You don’t have to chop, dice, mince, or julienne to have a healthy meal. And for busy students, 9-to-5ers, and families, that’s just not realistic most nights. Let’s talk about the easiest ways to get the benefits of produce without the hassle.

We’ve always heard “fresh is best.” And maybe that was true when you could walk out your back door, pick produce off the vine, bring it inside, and prepare it for dinner. Nowadays, when most of us have never seen where our produce comes from, and couldn’t without a passport, it’s not quite the same.

Much of the produce in grocery stores is harvested, transported, stored, and displayed before it ever reaches your kitchen. Depending on the fruit or vegetable, that can mean days to weeks between harvest and dinner. During that time, delicate produce like leafy greens and berries can lose nutrients, especially vitamin C and folate. They still keep their fiber and minerals, and they can still be very healthy, but it’s not exactly farm-to-table.

Frozen produce, on the other hand, is usually picked at peak ripeness, blanched, and frozen quickly to help preserve nutrients. The blanching process can reduce some nutrients, especially vitamin C and B vitamins, but even with that loss, frozen vegetables are often nutritionally comparable to fresh. In some cases, they may even retain more vitamin C, beta-carotene, or folate than fresh produce that has been sitting in storage.

So, what produce is most likely to lose nutritional value during transport, and which produce holds up better?

Most likely to lose nutrients during transport

• Spinach

• Baby spinach

• Leaf lettuce

• Romaine

• Spring mix

• Fresh herbs, especially basil, cilantro, and parsley

• Broccoli

• Green beans

• Fresh peas

• Sweet corn

• Strawberries

• Raspberries

• Blackberries

• Blueberries

• Pre-cut fruit

• Pre-cut vegetables

These are most likely to lose vitamin C, folate, some carotenoids, polyphenols, anthocyanins, chlorophyll, and natural sugars. Nutrients that are sensitive to heat, oxygen, light, and time tend to decline first.

Most likely to retain nutrients during transport

• Carrots

• Sweet potatoes

• Potatoes

• Beets

• Turnips

• Rutabaga

• Winter squash

• Pumpkin

• Onions

• Garlic

• Cabbage

• Apples

• Oranges

• Grapefruit

• Lemons

• Pomegranates

These tend to retain nutrients better because they are denser, sturdier, and often protected by skins, peels, or rinds. Fiber, minerals, and starches are generally much more stable during transport.

Besides nutrient retention, frozen vegetables also make healthy cooking much easier.

Let’s say you want to make a stir fry with lots of vegetables. You can chop an onion, a red bell pepper, a green bell pepper, broccoli, green beans, several mushrooms, and maybe a carrot. Oh, and don’t forget to wash and peel before you chop. And on a Saturday, when you have no plans and are really craving that dish, you might do all that.

But on a weeknight, when you just want a healthy meal and don’t want to spend an hour chopping, you might prepare one or two vegetables and call it a day. Or you could open your freezer, grab a frozen stir fry mix, and toss it in a pan.

Healthy. Easy. Diverse array of vegetables. Done.

Another bonus: frozen vegetables are already chopped. They’re ready to be thrown into a pan and heated up, and because they were blanched before they were frozen, you can cut down on your cook time. As Ina Garten says, “How fabulous is that?” Even the Barefoot Contessa herself has been known to use frozen vegetables from time to time.

But surely if frozen vegetables are healthy and more convenient, they must be more expensive, right?

Wrong again.

Because fresh produce often has parts that get thrown away, and because it can spoil before you get around to using it, frozen vegetables are often cheaper per serving. Frozen also has the added bonus of a ridiculously long shelf life. So if you decide to eat out one night and derail your planned menu for the week, your frozen vegetables will patiently wait for you. No judgment. No slimy spinach bag in the back of the fridge silently accusing you.

Let’s compare the cost of edible cup equivalents of fresh vs frozen produce.

Usually cheaper frozen

• Spinach

• Broccoli

• Corn

• Peas

• Green beans

• Mixed vegetables

• Berries: strawberries, blueberries, raspberries, blackberries

• Mango, pineapple, cherries

• Out-of-season vegetables

• Vegetables you may not use quickly

Often cheaper fresh

• Bananas

• Apples

• Oranges

• Carrots

• Onions

• Potatoes

• Cabbage

• Sweet potatoes

• Garlic

• In-season local vegetables

• Produce sold in bulk or on sale

Conveniently, the produce that is often cheaper fresh is also the produce that tends to retain nutrients better during transport and has a longer shelf life. So the easiest strategy is this: buy the produce that spoils quickly frozen, and buy the sturdier staples fresh.

What about canned produce?

Canned produce definitely has a place on our pantry shelves. While the heat used during canning can reduce folate, vitamin C, and some B vitamins, fiber and minerals are strongly retained. So for foods where vitamin C and B vitamins are the main nutritional benefit, I would usually stick with fresh or frozen.

But for foods like tomatoes, beans, corn, pumpkin, beets, and artichokes, canned can be a great, affordable, and much easier alternative to fresh.

One thing to watch out for: canned produce can contain added sodium or sugar. Many canned beans and vegetables are packed with added salt, and canned fruit is sometimes packed in syrup. These are sneaky ways sodium and added sugars make their way into our diets.

When picking canned produce, look for low-sodium or no-salt-added labels. For fruit, look for options packed in water, 100% juice, or no-sugar-added juice instead of heavy syrup.

And what about local produce?

Local produce can be one of the healthiest options if it was picked recently and you use it quickly. If you buy something from a local farmstand and cook it within a few days, great.

But if you aren’t planning to use it soon, or you don’t want to break down that lovely butternut squash you just bought because it looks less like dinner and more like something for which a power tool might be required, frozen might be the better option.

Similar to the fresh-versus-frozen cost breakdown above, local produce can also be more expensive. Local farms often have higher costs because they operate at smaller volumes and rely on more manual labor than large industrial farms. That cost often gets passed on to the consumer.

If cost isn’t an issue, supporting local farms can be a great way to get fresh produce that was likely picked close to peak ripeness. But for most families, cheaper and more convenient options, like grocery store produce and frozen vegetables, are more realistic. And if chosen well, they can still be nutritious, delicious, and much easier to fit into real life.

Eating produce is one of the many ways we can support our health and longevity, but it shouldn’t come at the cost of your time and sanity. Making small changes, like using frozen vegetables when you don’t feel like chopping, is a great way to keep meals healthy while saving time and energy.

At the end of the day, the healthiest vegetables are the ones you actually eat. Fresh, frozen, canned, local, grocery store — they can all be good choices. The goal is not to make produce more complicated or to feel guilty about taking shortcuts. The goal is to make healthy eating easier, more affordable, and more realistic. If frozen vegetables help you get more produce onto your plate on a busy weeknight, that is not a compromise, that’s a win.
