What is Konjac? Its Benefits, Side Effects and Uses

What Is Konjac?

Konjac and konnyaku are popular names for Amorphophallus Konjac, a vegetable species endemic to Yunnan in southwest China with an edible corm. It's also called konjaku, konnyaku potato, devil's tongue, or elephant yam. Konjac contains glucomannan, a fibre commonly used in weight loss products.

It grows in mild subtropical to tropical regions of East and Southeast Asia, from China and Japan to Indonesia and Vietnam. It is a perennial plant with huge corms that can reach 25 cm (10 in) in diameter. Its starchy (bulb-like) "corm" is used to generate nutritious noodles and grain replacements like cauliflower rice.

This plant's corm-based cuisine, known in English as konnyaku, is largely prepared and consumed in China, Japan, and Korea. While some studies, such as those published in Obesity Treatment 2020, show potential benefits, further research is needed to determine its benefits for weight loss.

What is Konjac Glucomannan

Konjac has its secret weapon, and that is known as glucomannan (pronounced gloo-ko-man-nan). Konjac glucomannan is a natural thickening agent and source of fibre that may help with weight management by promoting feelings of fullness.

Ever heard of konjac?

Konjac may not be well-known, but this interesting root vegetable has been a dietary staple in East Asia for generations. It is a natural, fibre-rich alternative to rice and noodles! It is widely produced, mainly in Japan, China and Indonesia. It is also used to make Konjac flour and jelly, which is a vegan alternative to gelato! These flours are combined to make konnyaku cake, which is the secret ingredient in those delicious shirataki noodles you may have had in a Japanese restaurant, so consider Konjac the next time you are looking for something different and healthy.

While Konjac is a natural substance, be aware of weight loss medication that contains it. Some supplements may contain hidden and possibly hazardous substances. Because nutritional supplements are not as closely controlled as drugs, search for items that have been certified by trustworthy organisations to assure their safety and quality.

What are the benefits of Konjac?

Ever wonder what makes Konjac so filling? Let's explore the surprising benefits of Konjac:

Skin Health

A 2013 research discovered that Konjac can improve skin health and reduce acne. It is said to speed up wound healing and minimize allergic responses. Also, Konjac sponges are an excellent beauty product for cleaning your face from everyday dirt and grime.

Weight loss

Fibre adds richness. Consuming it regularly keeps you feeling fuller for longer, minimising your urge to overeat or snack between meals. Konjac also expands in the stomach, which helps you feel full. According to a 2005 survey, a 1,200-calorie diet that contained a glucomannan fibre supplement resulted in more weight reduction than a 1,200-calorie diet with a placebo.

Increased immunity

The Konjac plant's antibacterial and antioxidant properties are thought to boost immunity. Your body may be able to combat common infections like the cold and flu more efficiently.

Oral health benefits

Because the Konjac plant includes antibacterial qualities, it helps alleviate minor oral health issues like toothaches. The Konjac plant can help clean your teeth and combat germs.

Improves digestion

Konjac is water soluble, which improves digestion. It can help strengthen your digestive system, making it an excellent natural cure for anyone with digestive issues. It may also help with constipation and hemorrhoids.

Helps regulate diabetes

Konjac contains glucomannan, which is beneficial for managing blood sugar levels in the body, thereby assisting in the management and treatment of diabetes.

What does it taste like?

The topic of what Konjac tastes like is both humorous and intriguing. According to most reports, when eaten alone, it does not taste like much. While it has a somewhat grassy and oceany fragrance, this does not typically convert into flavour when cooked. It has a slight tinge of salt, but it's quite mild, making it a blank slate.

Its gelatinous porous nature, paired with its neutrality, allows it to absorb the tastes of whatever it is cooked with, making it a culinary chameleon. And, being a low-carb, gluten-free vegetable, it is ideal for a variety of dietary demands. It is a popular supplement for individuals following keto, paleo, or low-glycemic diets. Glucomannan, extracted from Konjac root and a popular ingredient in Konjac -based low calorie foods, is a water-soluble dietary fibre derived from dehydrated Konjac and has much higher viscidity than other related additions when used in equal doses. This implies that it may thicken and emulsify a food product without adding any taste.

Konjac Pasta

On the other hand, Konjac pasta, such as our slim variety, is popular because they have the same texture and bite as regular spaghetti. Its neutral flavour compliments a variety of pasta dishes, adding a good twist to any meal. Additionally, its gluten-free nature makes it attractive to people with gluten intolerance and celiac disease, providing a safer alternative.
