Healthy & Delicious Konnyaku on Your Table
What's special about konnyaku?This traditional and historical food was introduced to Japan from China together with Buddhism in the 8th century. It is made by gelatinizing glucomannan, the polysaccharide found in konnyaku imo (root), and then setting it with an alkaline solution (calcium hydroxide). Konnyaku has long been called “spring cleaning for the bowels” and is said to improve and regulate the gut environment, aiding the excretion of waste. Konnyaku production is one of the representative local industries of Gunma Prefecture, which accounts for around 94% of Japan’s konnyaku imo production.
Why is konnyaku good for health and beauty?There are three main reasons.
(1) Healthful composition, with low calories, low carbs, and zero fat. It’s a boom for people looking to restrict calories and sugar intake.
(2) It includes dietary fiber, which is not absorbed in the bowels and has a detox effect that helps to expel waste.
(3) The skin of konnyaku imo includes ceramide, a moisturizing ingredient, so it can be expected to deliver beautifying effects.
How is the nutritional value of konnyaku different from rice, bread, and noodles?Konnyaku is far healthier than carbohydrates. However, it has a distinctive odor, so it is preprocessed before cooking to remove odor and bitterness.
What are some good ways to eat and enjoy konnyaku?It can be used as a boiled or stewed ingredient in classic washoku or eaten raw as thin konnyaku noodles and sashimi konnyaku slices.
Konnyaku is attracting attention as a substitute ingredient to reduce intake of carbohydrates and calories.Konnyaku noodles are a substitute of ramen and pasta, and rice konnyaku (in the shape of rice grains) can partially replace rice.
There are konnyaku products in many other forms to suit different preparation methods. As a raw material, it is used in sweet jellies and other desserts, where it improves texture and consistency, in paste-based items such as chikuwa, where it maintains moisture and shape, and in bread and cakes.
