Understanding the Carbs in Beets
Beets are a root vegetable known for their vibrant color and earthy sweetness. This natural sweetness is a result of their carbohydrate and sugar content, which is higher than that of many other non-starchy vegetables like leafy greens or broccoli. For those on a strict ketogenic diet, the carb count in beets can be prohibitive, but for individuals following a more flexible low-carb plan, they can be a nutritious and delicious addition. A standard serving of 100 grams of raw beets contains approximately 9.6 grams of total carbohydrates, with 6.8 grams of that coming from sugar and 2.8 grams from fiber.
The key to fitting beets into a low-carb diet lies in understanding net carbs. Net carbs are calculated by subtracting the fiber content from the total carbohydrates. Since fiber is not digested or absorbed by the body in the same way as other carbs, it doesn't raise blood sugar levels. For example, 100 grams of raw beets (roughly 3/4 cup) contains 6.8 grams of net carbs (9.6g total carbs - 2.8g fiber). While this isn't as low as spinach (about 0.4g net carbs per cup) or broccoli (about 4g net carbs per cup), it's far from the carb load of potatoes or other starchy root vegetables.
The Glycemic Index vs. Glycemic Load
Another important concept is the difference between glycemic index (GI) and glycemic load (GL). The glycemic index measures how quickly a carbohydrate-containing food raises blood sugar levels, while the glycemic load takes into account both the GI and the amount of carbs in a typical serving.
- Glycemic Index (GI): Beets have a medium GI of around 61.
- Glycemic Load (GL): The glycemic load for a typical serving of beets is quite low, around 5, because the portion size is not high in total carbs.
This means that while the sugars in beets are absorbed relatively quickly, the small quantity of carbs in a normal serving prevents a major blood sugar spike.
How to Enjoy Beets on a Low-Carb Diet
For those managing their carbohydrate intake, moderation is key. Rather than making them the star of every meal, think of beets as a flavorful accent. Here are some simple ways to incorporate them:
- Salad Enhancer: Shred or thinly slice a small amount of raw beets and sprinkle them over your salad greens for extra color and crunch.
- Roasted Side Dish: Roast a few small beets with olive oil and herbs alongside other low-carb vegetables like Brussels sprouts or broccoli for a flavorful side dish.
- Pickled Treats: Make or buy pickled beets, which are often prepared with a low-sugar brine and offer a tangy, satisfying crunch.
- Beetroot Powder: A small teaspoon of beetroot powder can provide a concentrated dose of nutrients with only 1g of net carbs, perfect for adding to smoothies.

The Health Benefits of Beets
Beyond their nutritional profile, beets are packed with health-promoting compounds. They are a great source of folate (Vitamin B9), manganese, potassium, and Vitamin C. The vibrant red color comes from compounds called betalains, which act as powerful antioxidants and possess anti-inflammatory properties.
Furthermore, beets are rich in inorganic nitrates, which the body converts into nitric oxide. Nitric oxide helps to relax and dilate blood vessels, leading to lower blood pressure and improved blood flow. This can also enhance exercise performance and increase stamina, making them a popular supplement for athletes. For diabetics, this can also be a key benefit for managing blood pressure, a common complication of the disease.
Conclusion
For those questioning "Are beets ok on a low carb diet?", the answer is a nuanced 'yes, in moderation'. Beets are not a "free food" like leafy greens, and they must be accounted for in your daily carb allowance. However, their high fiber content, powerful antioxidant properties, and low glycemic load when consumed in small portions make them a viable and healthy option. They offer a unique nutritional punch that can support heart health and exercise performance without significantly spiking blood sugar. The key is mindful consumption and integrating them as a flavorful, nutrient-dense accent to your low-carb meals, rather than as a primary component.
