Acorn squash is a type of winter squash that is shaped like an acorn. It has a sweet, nutty flavor and is a popular choice for many fall recipes. But is acorn squash a good choice for people with diabetes? Keep reading to find out.
What is Acorn Squash?
Acorn squash is a member of the Cucurbitaceae family, which also includes pumpkins, zucchini, and cucumbers. It gets its name from its acorn-like shape. The squash has a hard, green rind with orange or yellow flesh inside.
Some key facts about acorn squash:
- Native to North and Central America.
- In season during the fall and early winter.
- Has a mildly sweet and nutty taste.
- The flesh can range in color from pale yellow to orange.
- An excellent source of vitamins A and C, as well as potassium and fiber.
Compared to other winter squash like butternut or hubbard, acorn squash is smaller and has a smoother rind. When cooked, the flesh becomes soft and takes on a creamy, almost potato-like texture.
Acorn Squash Nutrition Facts
Here is an overview of the nutrition found in 1 cup of cooked, cubed acorn squash (from the USDA):

Now let’s look specifically at why acorn squash can be a good choice for people with diabetes.
Acorn Squash and Diabetes
For people with diabetes, foods that are low in carbohydrates and have a low glycemic index are usually recommended. The glycemic index measures how quickly a food causes blood glucose levels to rise. Foods with a high GI cause sharper spikes in blood sugar.
Acorn squash has a low glycemic index of just 15 (1). This means the carbohydrates in acorn squash are absorbed more slowly and cause a more gradual rise in blood sugar compared to high GI foods like potatoes or white rice.
In addition, acorn squash is high in fiber. One cup contains 7 grams of fiber, providing 28% of the recommended Daily Value. Fiber helps slow the digestion of sugars and absorption of carbohydrates from foods. This can help prevent unhealthy spikes and crashes in blood glucose levels.
Research has found that increased fiber intake, especially from fruits, vegetables, and whole grains, is associated with improved blood sugar control in people with type 1 and type 2 diabetes (2).
Beyond the carbohydrate and fiber content, acorn squash also provides nutrients that can benefit people with diabetes:
- Vitamin A – Helps maintain eye and skin health. Diabetes can increase the risk of eye problems over time.
- Vitamin C – An antioxidant that may help reduce oxidative stress, inflammation, and vascular damage related to diabetes.
- Potassium – Needed for proper nerve and muscle function. Certain diabetes medications can deplete potassium levels.
Overall, acorn squash is a nutrient-dense, low GI food that can be part of a healthy diabetes diet. Its fiber and antioxidant content are two particular benefits.
Tips for Cooking Acorn Squash
When cooking acorn squash:
- Cut it in half or into wedges to make it easier to cook and eat.
- Roast, bake, or microwave squash to soften the tough flesh.
- Roasting brings out the sweetness and intensifies the flavor.
- Season it with herbs and spices instead of adding sugar or butter.
- Stuff roasted squash with lean proteins, grains, beans, or vegetables.
- Puree cooked squash and add to soups or smoothies.
- Swap it for starchy foods in recipes – use spaghetti squash instead of pasta, for example.
Focus on low fat cooking methods like roasting, steaming, or sautéing in broth instead of frying in oil or butter.

Potential Downsides of Acorn Squash
Acorn squash is very nutritious and diabetes-friendly overall. However, there are a couple potential downsides to keep in mind:
- Carb content – While low glycemic, acorn squash is still relatively high in carbohydrates with 28g per cup. Portion sizes should be monitored.
- Dense and heavy – The heaviness of acorn squash can cause digestive issues like gas or bloating when eaten in large amounts.
As with any healthy food, moderation is key. Stick to reasonable portion sizes of acorn squash and be aware of how your body responds to it. Some people find winter squash hard to digest.
Who Should Be Cautious with Acorn Squash?
Acorn squash is safe for most people with diabetes. However, there are a few cases where caution is recommended:
- People with digestive issues like IBS may want to avoid acorn squash due to its high fiber content.
- Those who need to restrict carbohydrates like people following a keto diet may want to limit portion sizes.
- Anyone with an allergy or sensitivity to squash should avoid acorn squash.
If you take diabetes medication, talk to your healthcare provider about whether the fiber in acorn squash could interfere with medication absorption.
As with any new foods, it’s wise to eat a small amount of acorn squash first and see how your body responds. Discontinue use if you experience any digestive upset or adverse effects.
How Much Acorn Squash Can You Eat in a Day?
There is no standard recommended serving size for acorn squash. The amount that can be eaten per day depends on your calorie, carb, and fiber needs as part of an overall healthy diabetes diet.
As a general guide:
