The Surprising Health Benefits of Agar from Weight Loss to Gut Health

The health benefits of Agar are surprising and varied. Increasingly, it is being recognised as a superfood, due to the amazing health benefits it offers when consumed as part of our daily diet. Let’s explore some of the ways in which it supports our wellbeing below.

agar's benefits Agar is the name for the natural jelly produced by certain species of red seaweeds, and it is a nourishing food that has been part of traditional diets across Asia for centuries because of its health benefits and versatility in cooking.

Agar – A “Functional Food‘ to Improve Health and Wellbeing

Agar is dubbed a ‘functional food’ as it contains bioactive compounds that provide a clinically proven and documented health benefit and are therefore important for the prevention, management and treatment of chronic diseases in our modern age. There are a number of different health benefits offered by agar ranging from weight loss to gut health.

Agar is Fat Free and Linked to Weight Loss

Some cultures strong associate Agar with natural weight loss as well as helping to maintain healthy weight. It’s claimed that some Japanese women use agar every spring to cleanse their bodies (to lose a little extra weight and for general wellbeing), by adding half a teaspoon of Agar to their tea and drinking it 10 minutes before the evening meal.  

Agar contains virtually no calories, no cholesterol, is fat-free and is 80% fibre, some of which is transformed into a gel-like substance that bulks up in the gut with some interesting benefits: It is claimed that Agar:

  • reduces appetite. As a water-soluble indigestible fibre and a hydrophilic colloid, Agar asorbs water and increases the bulk of a meal with very few calories, giving a feeling of fullness that helps those who consume it reduce their overall food intake. According to Professor Takako Yasuoka, this creates a feeling of fullness, thus reducing the need for much food.
  • supports the elimination of waste from the stomach and the intestines by stimulating the large bowel muscle contraction. Historically, Agar has been used therapeutically as a daily treatment for chronic constipation because of its mild laxative properties.
  • Acts as a natural fat blocker because it absorbs glucose in the stomach, passing it through the digestive system quickly, inhibiting its storage as fat.
  • Helps to dissolve cholesterol by calming the liver and absorbing bile.  This is important as loosing weight will mobilise energy stored as fat, which will be released into the bloodstream.
  • Creates creamy textures in food without the need for sugar or fat, resulting in healthy and satisfying dishes with far fewer calories.

Agar is Beneficial to Lowering GI levels, Supporting those with Diabetes & Cholesterol

Scientific studies have shown that Agar has beneficial effects on glucose intolerance in people with type 2 diabetes.  A diet supplemented with Agar can promote better blood sugar and glucose management, although research is ongoing as to the extent of these benefits.

Studies indicate that the benefits of consuming agar are likely linked to lower GI levels because agar is very rich in soluble fibre which bind to sugar molecules in other foods we eat, slowing their absorption into the bloodstream. Eating agar with, or as part of a meal, therefore lowers the overall glycaemic index of the meal to prevent blood sugar spikes immediately after eating. This, in turn, helps to control appetite and prevent the body from storing excess fat.

There are indications agar may help to reduce the risk of GI cancer and may lower cholesterol as it is a good source of foliate and choline.  Foliate consumption has many benefits but protection against certain cancers (bowel, colon* & other parts of the digestive tract) has been given it lots of visibility recently. Choline has been shown to protect and/or heal the liver from certain types of damage, additionally, it may help lower cholesterol and homocysteine levels associated with cardiovascular disease. This is an area where more research is needed, but there are some positive first signs.

Agar Contains Numerous Minerals & Fatty Acids Essential for Optimal Health

Agar is a good source of many important minerals: manganese, magnesium & iron, and moderate levels of calcium, potassium, zinc, copper, choline, folate (B9), vitamins E and K. In addition, the omega 3 to omega 6 fatty acid ratio of agar seaweed jelly is 25:1, which is a major benefit as our typical diets are often too heavy on the omega-6s – for optimal health, we should consume more omega-3 than omega-6 fatty acids.

Additionally agar is low in sodium so a good alternative for those on a low sodium diet.

Agar Can Support Digestion and Gut Health

Because of its high soluble fiber content (~80%), Agar can aid digestion and gut health.  Soluble fibers form a gel-like material in the gut that can be readily fermented by the bacteria in the colon*. The fibre in agar absorbs and retains water which sends satiety signals. This is great for keeping us full, reducing appetite and regulating hunger.

Ongoing research into the health and wellbeing benefits of agar indicates that agar has a positive effect on colon health and may be able to be used to treat colon disorders and cancer.

Agar -A Vegan Collagen Source?

The sulphated polysaccharides found in agar, called galactans, may be said to play a role similar to that of collagen in the body by preserving and improving joints, membranes, skin and the gut lining. As collagen production in or body naturally declines with age, supplementing collagen or the galactans found in agar could mitigate the ageing process and deterioration. Research measuring the ability of compounds found in seaweed and agar suggests that it may also help to reduce inflammation – watch this space!

What is the Best Agar to Buy?

Not all agar is created equal. Although many red seaweeds or sea vegetables produce agar, some varieties produce better quality agar and in larger amounts. Different seaweeds grow in different environments and different extraction techniques can be used resulting in end products with varied characteristics, so agar quality varies from producer to producer. Whatever you buy, always buy seaweeds which have been tested for contaminants.

Since New Zealand no longer produces food-grade agar, Pacific Harvest imports high-quality Agar from India that has been rigorously tested for contaminants to ensure its nutritional profile is preserved and it meets the highest food grade standards to support health and wellbeing.
