Ginkgo nuts might not be the first thing that comes to mind when you think about superfoods, but for centuries, these small, ivory-colored seeds have been treasured in parts of Asia for their unique taste and potential health benefits. Derived from the Ginkgo biloba tree — one of the oldest living tree species in the world — ginkgo nuts carry both cultural and medicinal significance.
They’re often served during special occasions, added to traditional dishes, and even used in herbal medicine. However, like many natural foods, ginkgo nuts come with both benefits and risks, so understanding how to consume them properly is essential. In this guide, we’ll explore everything you need to know about ginkgo nuts: their nutritional profile, health benefits, potential side effects, best ways to eat them, and safety tips.
What Are Ginkgo Nuts?
Ginkgo nuts are the seeds of the Ginkgo biloba tree, a plant often referred to as a “living fossil” because it has existed for over 200 million years. The tree is native to China but is now cultivated in various countries, especially in Japan, Korea, and the United States.
These nuts are enclosed in a fleshy, yellow outer fruit that has a notoriously strong, unpleasant smell (often compared to rancid butter). Once the smelly fruit layer is removed, the seed inside is encased in a hard shell. The edible kernel — what we call the ginkgo nut — has a soft, chewy texture and a mild, slightly bitter flavor.
In traditional Chinese, Japanese, and Korean cuisines, ginkgo nuts are often added to soups, congee, rice dishes, and desserts. They’re also served during weddings, New Year celebrations, and other cultural events.
