Beets: Officially a Non-Starchy Vegetable
One of the most common misconceptions about beets is that they are a starchy vegetable. This is likely because they are a root vegetable, a category that includes starchy examples like potatoes and cassava. However, authoritative health organizations like the American Diabetes Association classify beets as non-starchy. Their overall nutritional composition, particularly the ratio of sugars to starches, places them firmly in the low-starch category.
The Truth About Starch in a Beet
When you examine the carbohydrate makeup of a beet, it becomes clear why it is not considered starchy. The majority of a beet's carbohydrates come from simple sugars, specifically sucrose, glucose, and fructose.
- Raw red beets contain about 9.6 grams of total carbohydrates per 100 grams, with about 6.8 grams being simple sugars and 2.8 grams being fiber.
- Specialized research on sugar beets has even measured the starch content and found it to be insignificant, often less than 1% of the dry weight.
- Some nutrition databases, like the one used by FitAudit, simply list the starch content as 'n/d' or 'not detected,' further reinforcing its minimal presence.
The natural sweetness you taste in a beet is due to these sugars, not the complex carbohydrates associated with starch.
Comparing Beets to Starchy Vegetables
To fully understand the difference, a comparison with a truly starchy vegetable like a potato is helpful. The distribution of carbohydrates is the key factor.
| Feature | Beets (approx. 100g serving) | Potato (approx. 100g serving) |
|---|---|---|
| Classification | Non-Starchy Vegetable | Starchy Vegetable |
| Total Carbohydrates | ~9.6 g | ~17.5 g |
| Starch Content | Minimal, often <1% of dry weight | Substantial, over 80% of carbs |
| Sugar Content | ~6.8 g | ~0.8 g |
| Dietary Fiber | ~2.8 g | ~2.2 g |
As the table shows, a beet contains significantly more sugar and far less starch than a potato for a comparable serving size.
How Beets' Unique Carb Profile Affects Your Body
The combination of moderate natural sugars and high fiber in beets results in a different metabolic effect than pure sugar or starch. The fiber helps to slow down the absorption of the sugars into the bloodstream, preventing a rapid spike in blood glucose levels. This means that while beets do contain sugar, their fiber content makes them a more nutritionally sound choice than foods with refined sugars and little to no fiber.
Lists of other nutrients found in beets include:
- Folate (Vitamin B9): Crucial for cell function and tissue growth.
- Manganese: An essential trace mineral involved in nutrient metabolism.
- Potassium: Helps regulate blood pressure and is vital for heart health.
- Vitamin C: A powerful antioxidant that supports immune function.
- Nitrates: Converted by the body into nitric oxide, which dilates blood vessels and can lower blood pressure.
- Betalains: The pigment responsible for the beet's deep red color, with powerful antioxidant and anti-inflammatory properties.
For those managing blood sugar, it is helpful to note the glycemic load (GL), which accounts for both the glycemic index and the serving size. Although beets have a medium glycemic index (61), their GL is quite low (around 5), which means a typical serving does not have a major impact on blood sugar levels.
Conclusion
In conclusion, the amount of starch in a beet is minimal and functionally insignificant. Beets are a low-calorie, non-starchy vegetable that derives its carbohydrates primarily from natural sugars and dietary fiber. This nutritional profile provides numerous health benefits, including improved digestive health and heart health, without the high glycemic impact associated with starchy foods.

Cooking with Beets: A Guide
Beets are incredibly versatile and can be enjoyed in many ways. Roasting them brings out their natural sweetness and concentrates their flavors, while boiling them creates a tender texture suitable for salads. They can also be eaten raw, grated into slaws, or blended into smoothies for a nutrient boost. The greens of the beet plant are also edible and cook similarly to spinach or chard.
Remember to prepare beets in healthy ways, avoiding heavy sauces or excessive added fats, to maximize their nutritional benefits. Their unique flavor and nutrient-dense profile make them a great addition to any diet.
