Shiratake Spaghetti


Shirataki noodles are a type of Asian noodles (slightly thicker noodles) made primarily from glucomannan, a dietary fiber derived from konjac root, an Asian plant.

Today it is also possible to find different formats, for example in grain (like rice), rigatoni, …

What does shirataki mean?

The Japanese term “shirataki”, which describes the appearance of the spaghetti, means “white waterfall”; this is a clear reference to their transparency and jelly-like consistency.

What does shirataki pasta contain?

Shirataki spaghetti consists of 97% water and 3% konjac, which contains glucomannan, a water-soluble fiber that is able to absorb large amounts of water.

It is free of protein, fat and simple sugars, making it an attractive choice for those following a low-calorie or low-carbohydrate diet.

Due to its high glucomannan content and almost negligible calorie intake, Shirataki noodles have been used and designed for:

  • low-calorie regimes (diet for weight loss),
  • diabetics (the fiber contained can help regulate blood sugar levels and reduce the absorption of other carbohydrates/fats present in food)

How many grams of shirataki per day?

There is no “standard” amount of shirataki to eat daily, however, it is important not to consider it a one-size-fits-all replacement for all other foods, especially those rich in essential nutrients.

In fact, excessive consumption of Shirataki could lead to the neglect of other important foods in the diet. These noodles are extremely low in calories and lack many key nutrients such as protein, essential fats, vitamins and minerals, so relying too much on this food could potentially expose you to micronutrient deficiencies and dietary imbalances.

For some sensitive individuals (or those who are not accustomed to consuming fiber), excessive consumption may cause intestinal distress due to the high fiber content.
