The Truth About Carbs in Rhubarb Stalks
Yes, there are carbohydrates in rhubarb, but the total amount is quite low, especially when compared to many fruits with which it is often paired. The key to understanding rhubarb's place in a low-carb diet lies in its composition. For every cup of raw, diced rhubarb, there are approximately 5.5 grams of total carbohydrates. Crucially, a significant portion of this is dietary fiber. A single cup of raw, diced rhubarb provides about 2.2 grams of fiber, leaving a net carb count of roughly 3.3 grams. Net carbs are the carbohydrates that the body can digest and use for energy, and for those on ketogenic or other low-carb eating plans, this number is far more relevant.
Raw vs. Cooked: How Preparation Affects Carb Count
One of the most important considerations for rhubarb and its carb content is how it's prepared. Because of its tart flavor, rhubarb is almost always cooked, and it's frequently paired with large amounts of added sugar. This drastically changes its carbohydrate profile. A 3.5-ounce (100-gram) serving of cooked rhubarb with added sugar can contain over 30 grams of carbs. This is a stark contrast to the low-carb nature of the raw vegetable. When preparing rhubarb for a low-carb or keto diet, it is essential to use sugar substitutes like erythritol, stevia, or monk fruit. This allows you to enjoy its flavor without the high-sugar penalty.
Rhubarb's Role in a Low-Carb or Keto Diet
With its low net carb count, rhubarb is an excellent addition to a keto or low-carb diet. It provides flavor and texture without derailing your carb goals. Furthermore, rhubarb has a low glycemic index of around 15, which means it causes a small and mild increase in blood glucose levels. This is beneficial for anyone managing their blood sugar or trying to avoid the insulin spikes associated with high-carb foods. For those on a keto diet, rhubarb is a versatile ingredient that can be used in a variety of recipes, from desserts to savory dishes.
Low-Carb Rhubarb Recipes and Cooking Tips
- Compotes and Jams: Stew chopped rhubarb with a keto-friendly sweetener and a little water. You can combine it with low-carb berries like strawberries or raspberries for extra flavor.
- Crisps and Crumbles: Create a low-carb crisp by using a topping made from almond flour, coconut flakes, chopped nuts, and butter instead of traditional flour and sugar.
- Savory Sauces: The tartness of rhubarb can be a wonderful complement to savory dishes, such as a rhubarb sauce for pork or chicken, balanced with spices and a sugar alternative.
- Baked Goods: Use rhubarb in low-carb muffins or breads by incorporating almond or coconut flour and a keto-approved sweetener.
- Layered Desserts: Combine stewed rhubarb with full-fat Greek yogurt or cream and a keto sweetener to make a delicious rhubarb fool or parfait.
More Than Just Carbs: The Full Nutritional Profile
Beyond its low carb content, rhubarb offers a host of other nutritional benefits that make it a healthy dietary choice.

Rhubarb vs. Common Fruits: A Carb Comparison
To put rhubarb's carb count into perspective, here is a comparison of the total carbs per cup for raw, diced versions of rhubarb and some commonly paired or compared items. This table highlights why rhubarb is a smart choice for carb management.
| Food (raw, diced) | Serving Size | Total Carbs (g) | Net Carbs (g) | Fiber (g) |
|---|---|---|---|---|
| Rhubarb | 1 cup | ~5.5 | ~3.3 | ~2.2 |
| Strawberries | 1 cup (halved) | ~12.7 | ~9.2 | ~3.5 |
| Apples | 1 cup (chopped) | ~15.4 | ~12.3 | ~3.1 |
| Raspberries | 1 cup | ~14.7 | ~7.2 | ~7.5 |
The Critical Warning: Avoid the Leaves
It is absolutely essential to remember that while rhubarb stalks are edible, the leaves are toxic. Rhubarb leaves contain high levels of oxalic acid, which can be poisonous and cause kidney damage if consumed. Always remove and discard the leaves before preparing rhubarb stalks for cooking. This is a non-negotiable safety precaution for anyone preparing rhubarb.
Conclusion: Rhubarb's Low-Carb Appeal
When considering if there are carbs in rhubarb, the answer is a resounding yes, but they exist in a very manageable quantity for most dietary plans. The low net carb count and high fiber content make it a fantastic and versatile option for those on a low-carb or keto diet, provided you avoid adding traditional sugar during preparation. Rhubarb's tart flavor, combined with its impressive array of vitamins and antioxidants, solidifies its position as a healthy and flavorful addition to any meal plan.

A Quick Note on the Fruit vs. Vegetable Debate
As a final fun fact, while rhubarb is botanically classified as a vegetable, it is legally considered a fruit in the United States, a distinction made by a 1947 New York court decision. This was largely due to tariffs, but it explains why you often see it used in pies and jams like a fruit.
