Blood sugar

Low GI — tends to raise blood sugar slowly. GI values are approximate and vary with ripeness, variety and preparation. If you manage diabetes, ask your care team how this food fits your plan.

Pesticide residue & peeling

Relative residue level: Moderate — a rough guide, not a lab measurement. The thick peel you discard protects the fruit, so residue on the flesh is low. Rinse produce under running water before eating.
