What Are Konjac Noodles?

These noodles are available in two main types, namely plain yam noodles and Tofu Shirataki noodles.

The plain yam noodles, also called Shirataki, have a white semi-transparent colour and are mainly made from only the yam flour.

On the other hand, Tofu Shiitake also contains tofu that gives these noodles a creamy white and opaque colour. Tofu also adds a few carbohydrates to the mix.

As far as the uses of these noodles are concerned, they are traditionally used for stir fry and soups, but may also be used as an alternative to al dente pasta.

While it is true that these noodles can’t replace well-cooked pasta as they have their unique texture, but they can offer an option as a side dish to your weekly menu as many times as you want.

An Ideal food for individuals suffering from diabetes. The glucomannan fibre helps in regulating blood sugar levels in type II diabetes.

It helps in removing these bile acids from the body and in the process, it also helps in reducing levels of fat in the blood.

Hyperglycemia and Hypoglycemia

High Blood Pressure

Possible Food Poisoning Antidote

Some researchers also claim that it may act as an antidote to food poisoning.

In a laboratory study, 18 different food products were exposed to various bacteria including Salmonella and E. Coli and these bacteria were allowed to bind to the products.

The sesame seed extract and Konjac gum bounded the largest quantity of bacteria as measured by the levels of bound bacteria in these products.
