What research says
Found in some samples or products
These come from where it was grown, how it was processed or cooked, or what it was made into. They are not about the ingredient itself, so the signal does not count them.
-
Radiation in food5
Chestnuts from Sinop contained tiny amounts of natural radiation, far below the level considered a health concern.
-
Soil to nut uptake6
Chestnuts can take in lead, arsenic, chromium, cadmium and mercury from the soil they grow in.
Allergies and intolerances
These are about people with an allergy, an intolerance or coeliac disease. The signal is about the ingredient itself, and these are about the person eating it, so the signal does not count them.
-
Cross-reactive food allergy3
In people allergic to both chestnut and latex, chestnut mainly cross-reacts with one latex protein.
-
Nut protein reaction4
Some people allergic to chestnut but not latex react to a chestnut protein called Cas s 8.
The signal at the top counts the findings in people and in animal and lab studies. A concern in studies of people outranks animal and lab studies, and “No concerns” needs at least one finding in people. When most findings in people point one way, the page leans that way (“Mostly”), and every finding is still shown. Findings whose study type is not stated are shown but not counted. This page is a reference, not medical advice. It describes what regulators and published research say. Talk to a doctor or dietitian about your own diet.
