Jackfruit
Jackfruit is a large tropical fruit native to South Asia, containing fiber, vitamin C, and polyphenols. It is notable for its carbohydrate content and use as a meat substitute in plant-based cooking.
Also known as: Artocarpus heterophyllus, jack fruit, chakka

Jackfruit is the fruit of Artocarpus heterophyllus, a tree native to the Western Ghats of India and now cultivated across tropical regions including Southeast Asia, Africa, and South America. The fruit is exceptionally large, weighing 2–80 kg, with a thick, bumpy skin and fibrous, starchy flesh. Culinary uses range from ripe fruit eaten fresh or processed into jams, to unripe fruit used as a savory meat substitute in vegan and plant-based dishes due to its shredded texture when cooked.
Per 100 g of raw fresh jackfruit flesh, USDA data indicates approximately 73–74% water, 1.7 g protein, and 23 g carbohydrates, with 1.5 g dietary fiber, 13.7 mg vitamin C, and polyphenolic compounds including quercetin and kaempferol. The fiber content supports normal colonic bulk and transit, while the natural sugar concentration (approximately 19 g per 100 g fresh in ripe fruit) contributes to its moderate glycemic profile. Unripe jackfruit contains resistant starch, which is fermented by colonic bacteria and produces a lower acute glycemic response; this effect diminishes as the fruit ripens and starches convert to sugars.
Blood Sugar and Glycemic Response
Ripe jackfruit has a moderate glycemic index (GI approximately 50–75 depending on variety and ripeness), reflecting its natural sugar content balanced by fiber. Unripe jackfruit, with higher resistant starch, produces a lower glycemic response in acute feeding studies. Individual variation in glucose response is significant and depends on ripeness, portion size, and meal composition. For individuals managing blood glucose, portion control and pairing with protein or fat is relevant standard practice rather than jackfruit-specific advice.
Tolerance and Intake Guidance
Jackfruit is well tolerated in typical culinary portions (100–200 g fresh fruit). No established upper intake limit exists. Unripe jackfruit, when used as a meat substitute, may cause mild bloating or gas in susceptible individuals. Jackfruit is also high in FODMAPs (GOS), which can trigger digestive symptoms in individuals with Irritable Bowel Syndrome (IBS); those with IBS should exercise caution regardless of ripeness or preparation form. Allergy to jackfruit is rare but reported; cross-reactivity with birch pollen and, more broadly, within latex-fruit syndrome has been documented in some individuals with oral allergy syndrome. The fruit poses no established concerns for standard populations.
Frequently Asked Questions
Is jackfruit safe for people with diabetes?
Ripe jackfruit has a moderate glycemic index and is not inherently unsafe in the context of diabetes management, but portion control is important given its natural sugar content. Unripe jackfruit has lower glycemic impact due to resistant starch. Blood glucose response varies by individual, ripeness, and meal composition; monitoring personal response and consulting a healthcare provider is recommended.
Can jackfruit cause allergies?
True allergy to jackfruit is uncommon. Cross-reactivity with birch pollen and, more broadly, within latex-fruit syndrome may occur in individuals with oral allergy syndrome, typically causing itching or tingling in the mouth. Consult an allergist if you have a known tree pollen or latex allergy and experience symptoms after consuming jackfruit.
Is unripe jackfruit a good meat substitute?
Unripe jackfruit has a shredded, fibrous texture similar to pulled meat when cooked, making it popular in plant-based cuisine. However, it is low in protein (approximately 1–2 g per 100 g) and does not nutritionally replicate meat. It contributes carbohydrates and fiber but should not be relied upon as a protein source; complementary protein-rich foods such as legumes or tofu are needed to meet protein needs in plant-based meals.
