5 Types of People Who Should Avoid Eating Jackfruit: Experts Warn on Health Risks of ‘Kathal’

Jackfruit, known as kathal across India, is often hailed as a superfood due to its rich nutritional profile — packed with fibre, antioxidants, and essential vitamins like A, C, and B-complex. However, health experts caution that this tropical fruit isn’t suitable for everyone.

While jackfruit is celebrated for its versatility — used in curries, desserts, and even as a vegan meat substitute — certain groups of people should consume it cautiously or avoid it altogether due to its effects on allergies, digestion, and blood sugar levels.

Here are five categories of people who should be careful when including jackfruit in their diet:

1️⃣ People Allergic to Latex

Jackfruit contains compounds similar to those found in natural latex, making it risky for individuals with latex allergies. This condition, known as latex-fruit syndrome, can trigger cross-reactivity with fruits such as bananas, kiwis, and avocados.
Symptoms may include itching, swelling, hives, or even life-threatening anaphylaxis. A case report in PubMed Central detailed a woman who suffered severe allergic reactions after eating jackfruit due to her latex sensitivity.

2️⃣ People with Diabetes

Jackfruit’s naturally high sugar content and moderate-to-high glycaemic index (GI) can cause a spike in blood sugar levels. While unripe jackfruit may help control glucose in limited portions, ripe jackfruit or sweetened dishes can worsen blood sugar fluctuations.
Diabetics should eat jackfruit in small quantities, preferably alongside fibre or protein-rich foods, and seek medical advice before making it a dietary staple.

3️⃣ People with Kidney Problems

Jackfruit is rich in potassium, which is beneficial for most people but dangerous for those with chronic kidney disease (CKD). Impaired kidneys struggle to eliminate excess potassium, increasing the risk of hyperkalaemia — a condition that can cause muscle weakness and irregular heartbeat.
Patients with kidney disorders or on dialysis should limit or avoid potassium-rich foods like jackfruit, bananas, and avocados.

4️⃣ Individuals with Sensitive Digestion

Though rich in fibre, jackfruit can cause bloating, cramps, or diarrhoea when consumed in excess — particularly for people with Irritable Bowel Syndrome (IBS) or sensitive stomachs.
To avoid digestive discomfort, experts recommend consuming ripe or cooked jackfruit in small portions and drinking sufficient water to aid digestion.

5️⃣ Pregnant and Breastfeeding Women

Jackfruit isn’t inherently unsafe during pregnancy but can trigger bloating and loose stools due to its strong laxative effect. Women with gestational diabetes should also be cautious since the fruit can raise blood sugar levels.
In moderation, cooked jackfruit can offer nutrients like vitamin C and folate, but doctors advise consulting a gynaecologist or dietitian before regular consumption.

Conclusion

Jackfruit is undoubtedly a nutritious fruit with numerous benefits — from boosting immunity to supporting digestion. However, people with latex allergies, diabetes, kidney issues, digestive sensitivities, or pregnant women should consume it cautiously or under medical supervision.

Moderation is key to enjoying its flavour and health benefits without triggering adverse reactions.
