Bulgur is a nutritious whole grain that features in tabbouleh, pilafs, and grain bowls. Unlike many refined carbohydrates, it brings a meaningful amount of fiber — around 4.5 g per 100 g cooked — which helps slow digestion. But if you're watching blood sugar or managing carbohydrate intake, it's useful to know not just the glycemic index (GI) of bulgur, but the glycemic load (GL) of the actual portion you plan to eat.
This Bulgur Glycemic Load Calculator does exactly that. Enter your serving size in grams or cups, adjust the GI if needed, and optionally enter custom nutrition values from your package label. The tool returns your estimated GL, classifies it as low, medium, or high, and shows the net carbohydrate math step by step. It's designed for meal planners, people with diabetes or prediabetes, and anyone curious about how a whole-grain staple fits into a balanced diet.
📊 Serving Details
Bulgur typically scores 46–48. Use 48 for a standard cooked bulgur.
How to Use This Calculator
Start by entering your serving size in grams or cooked cups. The default assumes a typical 150 g cooked serving and a glycemic index of 48, which is a middle value for bulgur. If you know the GI of your specific bulgur, adjust the GI box. You can also tick “Use custom nutrition values per 100 g” if the package label lists different carbohydrate or fiber numbers, then enter those values. Press “Calculate Glycemic Load” and you’ll get the estimated GL, the category (low, medium, high), and a breakdown showing total carbs, fiber, net carbs, and the arithmetic behind the result.
The reset button restores the default values and clears the results, so you can quickly test different portion sizes or compare dry versus cooked amounts.
The Math Behind Glycemic Load
Glycemic load combines the quality of carbohydrate (glycemic index) with the quantity you actually eat. The formula is:
GL = (GI × available carbohydrate per serving) / 100
Available carbohydrate, sometimes called net carbs, is total carbohydrate minus dietary fiber, since fiber is not digested into glucose. Using standard values for cooked bulgur — 18.6 g total carbs and 4.5 g fiber per 100 g — a 150 g serving provides 27.9 g total carbs and 6.75 g fiber, so 21.15 g available carbs. With a GI of 48, the GL comes out to (48 × 21.15) / 100 = 10.15, which is just above the low/medium boundary of 10.
Because GL scales with portion size, it is a more practical guide than GI alone. A low-GI food can still produce a high GL if you eat a very large portion, while a moderate-GI food eaten in modest amounts may have a low GL.
Worked Examples
Here are common serving scenarios based on cooked bulgur with GI 48:
- Small side, 100 g: net carbs 14.1 g → GL ≈ 6.8 (low)
- Average serving, 150 g: net carbs 21.15 g → GL ≈ 10.2 (medium)
- Large bowl, 250 g: net carbs 35.25 g → GL ≈ 16.9 (medium)
- 1 US cup, 182 g: net carbs 25.7 g → GL ≈ 12.3 (medium)
Bulgur Reference Data
Nutrition values vary by brand and cooking method, but these are representative figures from USDA FoodData Central and published glycemic index tables.
| Form | Approx. GI | Total carbs / 100 g | Fiber / 100 g | Available carbs / 100 g |
|---|---|---|---|---|
| Bulgur, cooked | 46–48 | 18.6 g | 4.5 g | 14.1 g |
| Bulgur, dry | — | 75.9 g | 18.3 g | 57.6 g |
| Fine bulgur, cooked | ~48 | 18.6 g | 4.5 g | 14.1 g |
| Coarse bulgur, cooked | ~46 | 18.6 g | 4.5 g | 14.1 g |

Tips & Best Practices
- Keep the fiber: Don’t rinse overcooked bulgur excessively or remove the bran; fiber is what helps lower the glycemic response.
- Pair with protein and fat: Adding yogurt, chicken, chickpeas, olive oil, or nuts can slow digestion and flatten blood sugar spikes.
- Choose texture: Coarse bulgur may have a slightly lower GI than very fine bulgur because more intact grain structure slows digestion.
- Watch dry portions: Bulgur triples in volume when cooked, so check whether your recipe weights are dry or cooked before calculating.
Frequently Asked Questions
Is bulgur a low glycemic food? Yes. Cooked bulgur typically has a GI around 46–48, which is considered low. Its GL stays low or moderate in normal portions because fiber makes up a substantial part of its carbohydrate.
How is glycemic load different from glycemic index? GI ranks a food’s carbohydrate by how quickly it raises blood sugar, but it doesn’t consider portion size. GL adjusts for the actual grams of available carbohydrate you eat, so one slice of bread and half a loaf of the same bread can have very different GL values even though the GI is identical.
Can I use custom package values? Yes — use the custom nutrition option. Many whole-grain bulgur brands list slightly different carb and fiber values; entering the label values makes the result more accurate for your exact product.
Does cooking affect the numbers? Yes. Cooking hydrates the grain, so cooked bulgur has lower carbs per 100 g than dry bulgur. You should always match your serving unit to the state of the food you’re eating. If you start with dry bulgur, weigh it dry and use the dry nutrition values.
