Health Benefits of Konnyaku

What kind of nutrients does it have?
  • 1. Rich in fiber
    • About the same as that of 2 lettuce heads!*

      Konnyaku is rich in a dietary fiber called glucomannan which cleans out the body. Because of this benefit, konnyaku has long been called the “broom of the stomach” in Japan!

  • 2. High in calcium
    • Nearly twice the amount of that contained in broccoli!

      Kanazawa Konnyaku Rice is high in calcium, a mineral indispensable for bones and teeth. Calcium can be efficiently consumed by eating konnyaku because the type of calcium contained in konnyaku dissolves readily in acid and so it is easily absorbed.

Why is it said to be good for beauty, health, and weight loss efforts?
  • 1. Why it is a weight-loss and beauty helper
    Being that more than 90% of konnyaku is made up of water, it has no fat and has very few calories. Since its texture is pleasantly resilient, people naturally chew longer when they eat konnyaku. For this reason, people get full easier when eating konnyaku compared to other ingredients. As konnyaku is also rich in fiber, it alleviates constipation and is optimal for preventing overweight and obesity.
    Furthermore, recent research has found that the konjac corm––the main ingredient of konnyaku––is rich in ceramide, which preserves the moisture in skin.
  • 2. Why it is a health helper

    Glucomannan, the main component of Konnyaku, is said to have the following effects:

    • Prevention of colorectal diseases
    • Cholesterol control
    • Diabetes prevention
    Prevention of colorectal diseases:
    Its fiber (glucomannan) stimulates defecation and combined with other reasons, konnyaku is known to reduce the risk of diseases like colorectal cancer and colon polyps.
    Cholesterol control:
    Konnyaku is rich in fiber, which is indispensable for maintaining normal cholesterol levels. In addition, glucomannan suppresses the absorption of cholesterol in the small intestine.
    Diabetes prevention:
    Multiple studies have found that consuming glucomannan improves glucose tolerance and suppresses insulin secretion.
