If you’re trying to lose weight, by now you may have heard of shirataki noodles. These noodles were invented by the Japanese over 2000 years ago.
Shirataki noodles are made from flour ground from the bulbous root (or corm) of the Konjac plant. This flour is known as konjac flour and is not a carbohydrate like traditional flour. It is 100% soluble fiber which is combined at a ratio of 3% to 97% water to create a solid gel. When left in blocks this gel is called konnyaku. When formed into noodles it is called shirataki which means ‘white waterfall’. Traditional konnyaku is grey from the addition of seaweed to the mix.
Konnyaku and Shirataki are effectively calorie-free since the human body is incapable of converting fiber into energy. Even if konjac flour were a traditional carbohydrate, a 100-gram serve of shirataki would contain only 12 calories based on the three grams of fiber it contains and the fact that one gram of carbohydrate contains four calories.
Most of the health benefits of shirataki are derived from fiber content. The American Dietetic Association recommends 20-35 grams of fiber per day. The average American only consumes around 15 grams of fiber per day.

Warning: In the 1960s, a Japanese writer named Soichi Ohyake is rumored to have died of malnutrition after eating nothing but konnyaku and shirataki to lose weight.
So are shirataki noodles a superfood? The answer is a resounding ‘NO!’ The term superfood refers to highly nutritious foods. This doesn’t apply to shirataki noodles since the only nutrient is fiber.
