Oxalates in Chestnuts: A Simple Guide

If you love roasting chestnuts in the fall, you might wonder what those crunchy treats do to your body. One thing that comes up often is oxalates – a natural compound found in many plants. In chestnuts, oxalates are present but not as high as in foods like spinach or rhubarb. Understanding the amount and how it affects you can help you enjoy chestnuts without worry.

How Much Oxalate Do Chestnuts Contain?

Raw European chestnuts typically have about 30‑45 mg of oxalates per 100 grams. That’s roughly half a cup of peeled, cooked nuts. Compared to high‑oxalate foods that can reach 200 mg in the same serving size, chestnuts sit on the low‑to‑moderate side. If you’re tracking oxalate intake for kidney stone prevention, a typical snack of 30 grams (about a handful) adds only around 10‑15 mg to your daily total.

Tips to Keep Oxalate Intake Low

Even though chestnuts aren’t packed with oxalates, there are easy ways to keep the amount down. First, always cook them – boiling or roasting reduces oxalate levels by about 10‑15 %. Second, pair chestnuts with calcium‑rich foods like cheese or yogurt; calcium binds to oxalates in your gut and prevents absorption. Lastly, if you have a history of kidney stones, aim for no more than one serving of chestnuts per day and balance the rest of your meals with low‑oxalate options such as bananas, white rice, or dairy.

Bottom line: Chestnuts can be part of a healthy diet even if you need to watch oxalates. They give you fiber, vitamin C, and a pleasant taste without overloading your system. Just cook them properly, watch portion size, and pair them with calcium‑rich foods for the safest experience.
