Walnuts are grown on trees. They grow inside hard shells, which when cracked open produces that familiar wrinkly nut! Most of the world’s walnuts are grown and harvested in China. You can buy them still in the shell or without and they can be eaten both cooked and raw.

Despite all the benefits walnuts are quite calorific, there are about 618 calories per 100 grams of walnuts. They are still pretty healthy but if you want to start eating more walnuts make sure you are watching your overall consumption of fat. If you are looking for a snack we suggest limiting your serving size to about 7 halves.
