The 10 Best Frozen Foods for Blood Sugar

1. Frozen Broccoli

Frozen veggies and fruits are generally harvested at peak ripeness, and then they are blanched or flash-frozen to preserve their quality, flavor, and nutrients. We love frozen broccoli because it is pre-cut, slashing prep time. As a versatile veggie, broccoli is full of nutrients and fiber, with every cup of cooked frozen broccoli providing more than 5 grams of fiber. Plus, broccoli contains sulforaphane, a sulfur-containing compound that gives the veggie its distinct aroma and bitterness, and which may help manage blood sugar and insulin resistance.

Make crispy frozen broccoli by roasting or air-frying the florets. Our 14 Recipes That Start with a Bag of Frozen Broccoli also come in clutch on busy weeknights.

2. Frozen Spinach

We love using frozen spinach for side dishes. Since Popeye’s favorite veggie shrinks substantially when cooked, you can easily eat more of it in a sitting compared to fresh spinach. And that means you’ll consume more nutrients. In fact, 1 cup of cooked frozen spinach has 8 grams of fiber, compared to less than half a gram for a cup of raw spinach. Add frozen spinach to soups, stews, fritters, quiches, dips, and more—check out our 12 recipes featuring a bag of frozen spinach.

3. Frozen Kale

Kale is another leafy green that freezes well and has an impressive nutritional profile. One cup of cooked frozen kale has almost 4 grams of fiber. Plus, kale contains quercetin and kaempferol, antioxidants that may help lower blood sugar and improve insulin sensitivity. Use frozen kale to make soups, like our Chorizo, Potato & Kale Soup, or add a handful to smoothies like our Really Green Smoothie.

4. Frozen Corn

Corn is a perfect side dish because it is both a whole grain and a vegetable. When eaten in moderation, corn kernels are also a low- to moderate-glycemic food, meaning they are less likely to induce sudden spikes in blood sugar. You may be surprised that 1 cup of cooked frozen corn has 4 grams of fiber, making it an excellent grain choice to accompany protein-rich foods.

5. Frozen Peas

Frozen peas are another nutritious option that can be added to a variety of dishes. They are a good source of protein, fiber, and vitamins, and they have a low glycemic index, making them a great choice for managing blood sugar levels.

6. Frozen Green Beans

Frozen green beans are a tasty and nutritious option that can be added to a variety of dishes. They are a good source of protein, fiber, and vitamins, and they have a low glycemic index, making them a great choice for managing blood sugar levels.

7. Frozen Avocado

Avocados are packed with unsaturated fats that promote heart health. They are also an excellent fruit because they have little impact on blood sugar levels—1/2 cup of frozen avocado has 4 grams of fiber. The downside of fresh whole avocados is that they don’t last very long at room temperature before they turn soft and brown. Frozen is a perfect alternative if you would like to cut down on food waste while offering the same delicious taste in your recipes, especially when it comes to smoothies.

8. Frozen Fish

Protein helps slow digestion and blunts carb and sugar absorption, stabilizing blood sugar levels. Lean options like fish are excellent to include in a balanced meal pattern. Specifically, plain frozen fish like salmon and cod are full of nutrients. They are also a source of omega-3 fats, and 3 ounces of cooked salmon and cod contain 21 and 17 grams of protein, respectively. Not only that, many frozen fillets are pre-portioned and quick to thaw, saving on meal prep time.

9. Frozen Shrimp

If you love seafood, pick up a bag or two of frozen shrimp on your next grocery run. Shrimps are quick to defrost, and are packed with protein. Three ounces of cooked shrimp has 20 grams of protein. Pair shrimp with your favorite whole-grain pasta to make Creamy Lemon Pasta with Shrimp, grill to make shrimp tacos, or pair with frozen spinach to make One-Pot Garlicky Shrimp & Spinach.

10. Frozen Shelled Edamame

This plant-based protein is an excellent source of protein and fiber, boasting 18 grams of protein and 8 grams of fiber per cup. Edamame also has a relatively low glycemic load due to its high fiber and protein content, making it an ideal plant-based protein that won’t drastically raise blood sugar levels. Add edamame to your favorite stir-fry, boil it and toss into salads, or boil and blend to make Edamame Hummus.

Strategies to Select Frozen Foods for Healthy Blood Sugar Levels

When you’re out shopping, here’s how to choose nutritious frozen foods:

• Consider fiber content: When buying frozen veggies, fruits, and plant-based proteins, opt for those that offer a good source of fiber, meaning they have at least 3 grams of fiber per serving.
• Look at protein: For protein-rich frozen foods, look for options with at least 7 grams of protein per serving.
• Go as simple as possible: Buy plain frozen food items that have no added fat, sugar, salt, or breading, which provides the flexibility to season and dress your meals the way you want. Doing this gives you more control over managing your blood sugar.

The Bottom Line

Frozen foods can be part of a nutritious meal pattern as you manage your blood sugar levels. They can be just as nutritious as fresh, with the advantage of offering flexibility with meal creations. Stock up on plain fruits, vegetables, plant-based proteins, and fish and seafood the next time you’re in the grocery store to make flavorful and satisfying meals throughout the week.
