Each inulin and FOS are extracted from chicory root fiber, a pure dietary fiber that’s extracted utilizing sizzling water from a plant that is a part of the dandelion household. GOS is produced from lactose, which is sourced from animals. It additionally is not as well-studied as the opposite two.


Inulin can also be present in smaller quantities in complete wheat and a few greens and fruits, akin to asparagus, garlic and bananas. Information from 1999 (the latest obtainable) places the common American consumption of inulin naturally occurring in meals at 2.5 to three.5 grams a day.

Longer-chain inulin has a creamy mouthfeel, so it is typically used to assist scale back the fats content material in merchandise. Brief-chain inulin (FOS) tastes barely candy, so it is used to assist scale back a number of the sugar and sugar substitutes in meals and drinks.

Inulin dietary supplements and a few meals and drinks will use a mix of short- and longer-chain inulin. These blends are additionally generally utilized in analysis.

Chicory root fiber passes by way of your small gut after which is fermented by the micro organism in your giant gut. As famous above, taking in an excessive amount of too rapidly can result in digestive discomfort – which may occur with any fiber. As well as, some individuals appear to be extra delicate to inulin and FOS than others, and should must restrict their consumption.

The European Meals Security Affiliation has accepted the declare that consuming at the very least 12 grams of chicory inulin or FOS a day eases constipation. (There is not sufficient analysis to state this about GOS.)


Different well being advantages

Inulin and FOS additionally might scale back our calorie consumption and blood-sugar ranges and enhance calcium absorption.

Chicory root fiber appears to decelerate abdomen emptying and suppresses urge for food indicators within the mind, which may enable you eat much less. In small research, adults and kids of each regular and extra weight who took a complement of 12 to 16 grams a day consumed fewer energy.

A weight-loss examine of 44 individuals with pre-diabetes who have been receiving counseling from a dietitian discovered that the group taking inulin dietary supplements for 18 weeks had a weight lack of 7.6 % of physique weight, in contrast with a weight lack of four.9 % within the group taking cellulose, one other kind of fiber.

Although these findings are thrilling, there must be extra analysis on the results of inulin on people with pre-diabetes and Sort 2 diabetes to know whether or not it may be useful in these populations.

Relating to calcium, analysis suggests that getting eight grams of chicory root fiber a day improves absorption. Chicory root fiber makes the colon extra acidic, which will increase the floor space that may soak up vitamins and makes extra proteins that bind to calcium.

A year-long randomized management trial in 100 adolescents performed on the Agriculture Division’s Kids’s Vitamin Analysis Middle on the Baylor Faculty of Drugs discovered that the kids taking eight grams a day of chicory root fiber had larger ranges of calcium absorption and better bone mineral density, displaying that the extra calcium that was absorbed was deposited into bone.

How a lot inulin to intention for

In prehistoric occasions – after we have been consuming way more greens and gnawing at roots – it is estimated that our ancestors consumed about 135 grams of inulin a day. I would not suggest aiming for these ranges, given what our digestive ranges at the moment are accustomed. However we are able to realistically attain a lot decrease ranges that promote well being advantages.

Primarily based on analysis, intention for five grams of inulin a day to spice up the expansion of the probiotic Bifidobacteria in your intestine.

Hannah Holscher, registered dietitian and professor on the College of Illinois, recommends a gradual enhance each two weeks. “For example there’s [an energy] bar you want that is excessive in inulin that you just appear to be delicate to.

You may begin consuming 1 / 4 of the bar for per week or two, then one-half for a few weeks, and work as much as having the complete bar.”

How a lot has been added?

Firms aren’t required to specify the quantity of inulin of their merchandise on the label; will probably be included within the complete quantity of dietary fiber within the Vitamin Details desk.

If a meals or beverage that does not normally include fiber, akin to yogurt or flavored water, lists inulin as the one fiber ingredient, then the quantity of dietary fiber tells you what number of grams of inulin have been added.

If a meals is made with complete grains or different fiber-rich substances, akin to a cereal or granola bar, it may be robust to inform how a lot of the fiber is coming from inulin.

For those who’re attempting to eat fewer energy or enhance calcium absorption, I like to recommend beginning with the fundamentals earlier than including high-inulin meals and drinks or dietary supplements to your routine.

To soak up fewer energy, eat loads of non-starchy greens, enhance your general fiber consumption through pulses and small parts of complete grains, eat lean protein sources and up your water consumption.

For higher calcium absorption, ensure you’re taking it with vitamin D. Then you’ll be able to take into consideration whether or not chicory root fiber is one thing that would improve your weight loss plan.
