Glucomannan Benefits
Glucomannan is a bulk-forming agent and may have a positive influence on blood sugar levels by delaying stomach emptying. These actions also promote healthy cholesterol levels, thereby supporting cardiovascular health.
What is glucomannan?
Glucomannan is a water-soluble plant fibre extracted from the root of the konjac plant or elephant yam in Southeast Asia and consists of mannose and glucose sugars. It’s often used as a bulking agent in foods, especially in Southeast Asia, where it’s used to make things like noodles and herbal mixtures, as well as remedies to treat conditions like asthma.
It’s been used for centuries in traditional Japanese cooking and is highly prized for having a number of benefits. Its nickname is apparently “the broom of the intestines”, which gives you an idea of how good it is for your gut and general health!
What are the benefits of glucomannan?
Glucomannan is a renowned source of fibre. As we’re often told, fibre is essential for your digestive system to function at its best, helping to lower your risk of developing serious diseases.
Fibre is a complex carbohydrate, which means it can’t be absorbed by the small intestine – instead, it gets broken down in the large intestine. If you’re dealing with constipation, fibres like glucomannan bulk up the food in your gut so that it can pass easily along the intestines for normal bowel movements.
While many sources of fibre are recommended for gut health, glucomannan is renowned for its exceptional ability to absorb water, so much so that a small amount can turn an entire glass of water into a gel. This makes it particularly good for maintaining a healthy weight, as it gives the stomach a feeling of being full and helps stave off hunger pangs.
A study by the University of Tromso in Norway reported that people lost more weight by taking glucomannan than other high-fibre supplements. And research by the University of Reading suggested that glucomannan works well as a prebiotic, helping to encourage the growth of ‘friendly’ bacteria in the gut – such as bifidobacterium – which in turn has a positive effect on our immune system.
Glucomannan supplements help to control blood sugar levels, as it slows the absorption of sugar into the blood through the intestines, so you don’t suddenly have insulin spikes before a ‘sugar crash’, leading to lethargy and hunger pangs. This can also help prevent diabetes, as well as help control sugar levels for those who already have the condition.
And if you’re concerned about heart disease, glucomannan can help here too. According to The American Journal of Clinical Nutrition, it can reduce levels of total cholesterol and cause a drop in harmful LDL cholesterol, too. Their research suggested that it does this by altering how our liver produces cholesterol and how our body stores and uses fat.
How can I get more glucomannan in my diet?
Mixing one gram of glucomannan with water before meals can help you feel full and maintain a healthy weight. It’s important to wash it down with several glasses of water so that it doesn’t overly solidify and cause intestinal blockages. Another thing to be mindful of is that it can prevent certain medications from being absorbed into your gut, so it’s important to wait four hours after taking any medicines before getting your glucomannan fix.
