How we built this list
We ranked all published walnut kernels on Foodmetria that have a photo and the required nutrition data, using values per 100 g from the product label. Ties are broken by Nutri-Score and by how often shoppers scan the product. Rankings update automatically as label data changes. Read our methodology.
