Jackfruit can be consumed during pregnancy but requires caution. Generally safe but may cause allergic reactions; limited research. The key guidance from WHO: Eat in moderation; avoid if latex allergy (cross-reactivity). Potential concerns include: Latex-fruit syndrome in sensitive individuals. These risks are manageable when you follow the recommended limits. When consumed appropriately, jackfruit does offer benefits such as Fiber and Vitamin C.
A "Use Caution" rating means this food is generally fine during pregnancy but comes with a specific factor worth managing — a daily limit, a preparation requirement, or a moderation guideline — rather than a reason to avoid it outright. These ratings reflect general guidance from the FDA, ACOG, CDC, and USDA. The goal of the "caution" label is to flag what to pay attention to, not to suggest the food is unsafe when that factor is properly managed.
