What to Watch For
⚠️ Low Dietary Fiber
Jackfruit, raw contains only 1.5g of fiber per 100g — far below the recommended threshold for diabetes-friendly carbohydrates. Without fiber to slow digestion, the starches break down rapidly in the small intestine, causing a quicker glucose release into the bloodstream. The American Diabetes Association recommends choosing high-fiber carbohydrates (≥3g per serving) to help stabilize post-meal blood sugar. Pairing Jackfruit, raw with high-fiber vegetables or legumes can partially offset this effect.

Tips for Enjoying It
💡 Pair With Protein & Fiber
Eating alongside lean protein and non-starchy vegetables slows gastric emptying and blunts the post-meal blood sugar rise.
💡 Eat Whole, Not Juiced
Whole fruit contains fiber that buffers sugar absorption. Juices remove this fiber, causing a faster glucose spike.
💡 Check Your Own Response
Individual blood sugar responses vary. Use a glucose meter to understand how this food affects you personally.
💡 Glycemic Load Over Glycemic Index
GL accounts for both the speed AND amount of carbohydrate, making it more practical for real-world eating than GI alone.
Glycemic Load by Serving Size
| Portion | Weight | Carbs | Glycemic Load | Verdict |
|---|---|---|---|---|
| ½ Serving | 76g | 17.7g | 8.1 | Friendly |
| Standard Serving | 151g | 35.1g | 16.2 | Moderate |
| Restaurant Portion | 302g | 70.2g | 32.3 | High |
GL ≤10 = Low (Friendly) · 11–19 = Moderate · ≥20 = High (Limit).
The page-level verdict is based on GL per 100g; this table shows how portion size changes the actual GL you get.

Common Questions
Is Jackfruit a reasonable choice if you have diabetes?
Jackfruit sits at GL 10.7 — not the worst, not the best. The key is portion control and pairing. A small amount alongside vegetables and lean protein works well.
How much GL does Jackfruit have per serving?
Jackfruit has a glycemic load of 10.7 per 100g. A standard serving (1 medium, 151.0g) delivers a GL of 16.2. GI data from Sydney University GI Database (Atkinson et al., 2021).
How quickly does Jackfruit raise blood sugar?
With 1.5g of fiber per 100g, Jackfruit's GL of 10.7 means the blood sugar impact is moderate. The carbohydrates digest and absorb at a moderate pace. Pairing with protein and high-fiber foods can help slow absorption.
Why is fiber important for blood sugar control?
Dietary fiber slows carbohydrate digestion and absorption, leading to a more gradual blood sugar rise. Jackfruit has only 1.5g of fiber per 100g, which is one reason its glycemic load (10.7) is moderate. The ADA recommends choosing carbs with at least 3g of fiber per serving. Adding high-fiber foods like vegetables or legumes to your meal can help compensate.
Is the GI value accurate?
The GI of 49.1 for Jackfruit is estimated (Tier 3), not directly ISO-tested on this specific food. It is based on the weighted average GI of foods in the Fruits and Fruit Juices category from the International GI Tables (Atkinson et al., 2021). Actual GI may vary by variety, ripeness, cooking method, and individual response. We display estimated values with full transparency so you can make informed decisions.
