Inulin is a starchy substance found in many vegetables and fruits. Foods with a high inulin content, include Jerusalem artichoke, onion, leek, garlic, banana and chicory root. Inulin is one of only two Fructooligosaccharides (FOS) to be defined as a prebiotic.
Comparing Prebiotics & Probiotics: Understanding Their Differences & How They Work Together
Prebiotics are defined based on 3 criteria
1) The(food) source must be non-digestible and resistant to gastric acidity, hydrolysis by intestinal digestive enzymes, and gastrointestinal absorption.
2) It must be fermentable
3) Should, in a selective way, stimulate growth and/or metabolic activity of intestinal bacteria, which it does at the expense of pathogenic bacteria.
To put it more simply, your digestive system is unable to break down inulin, meaning it travels, unharmed, through to your bowel where it ferments and stimulates the growth of ‘good bacteria’ or probiotics. This nutrient selectively increases the production of both the lactic acid-producing bacteria (Lactobacillus species) and the bifidobacterium species of 'beneficial' bacteria. A healthy gut flora consists of a large amount of these ‘good bacteria’ that then serve to suppress pathogenic bacteria from flourishing.
Understanding How Inulin Supports Gut Health
Inulin, through the growth of ‘healthy bacteria’, promotes the healthy digestion and absorption of nutrients from food. As an indigestible fiber, it also helps to promote healthy elimination and is often used for the effective treatment of constipation, without having the common bulking effect that so many fiber supplements have. As a fiber, inulin may also have the added benefit of helping to regulate blood sugar, applicable not only to individuals with diabetes or those termed pre-diabetic but helpful to those looking to control cravings and weight gain.
Explore Inulin's Impact on Cholesterol
Inulin may decrease the body’s ability to make a certain type of fat called triglycerides. Many individuals with high cholesterol may also find that their triglyceride level is also high, or in fact that it is ONLY their triglyceride level that is out of range, equally as concerning. Inulin can significantly decrease triglyceride levels after only a couple of months of regular use.
Shopping For Quality Inulin Supplements
Pre and pro-biotics, when taken together, enhance each others' effects. This is why many companies are now including prebiotic fibre such as inulin along with the live cells of a probiotic. It is also found in many combination fiber supplements, mainly sourced from chicory root. Although less often, inulin, can also be found on its own. Recommended dosages range from 10-20 g/day, depending on the condition being treated. Consult a healthcare practitioner if supplementing with high doses, as malabsorption issues can result. Be sure to take inulin away from any medication or other supplements, to not interfere with their absorption.
