Tate & Lyle principal scientist, North America International Vitamin, Dr Melissa Kaczmarczyk – who’s talking at FoodNavigator-USA’s ‘Feeding the Gut Microbiome’ webinar this Thursday in a panel on prebiotic fibers and resistant starch – stated Tate & Lyle continues to be discovering new issues concerning the fiber, which it has been advertising and marketing within the US since 2007.
“We’re at the moment conducting analysis in rising and cutting-edge analysis areas akin to fiber and cognitive well being, metabolic well being and immunity, and now we have partnered with educational consultants at main universities to conduct these research.
“We’re additionally interested by how our prebiotic fibers work with probiotics.”
The intestine mind axis
PROMITOR soluble corn fiber (resistant maltodextrin) – which can be utilized for fiber fortification and sugar or fats discount – is classed as a dietary fiber by the FDA, and has additionally been proven to cut back blood glucose after a meal, stated Kaczmarczyk, with CPG firms now utilizing it in every thing from bars, cereals and baked items to confectionery, drinks, sauces, yogurt, and ice cream.
Its prebiotic results – it stimulates the expansion of helpful bacterial and reduces the presence of dangerous micro organism and putrefactive compounds within the intestine akin to ammonia – are additionally attracting curiosity from CPG firms seeking to make prebiotic claims on pack, stated Kaczmarczyk.
Nonetheless, we’re nonetheless simply scratching the floor, she stated, noting that we already know that some probiotics influence cognitive operate, however extra analysis is required on prebiotics: “There are some preliminary papers exhibiting that fibers can change microbiota that change chemical substances and pathways on the intestine mind axis, and so we have an interest to see if soluble corn fiber additionally has these properties.”
Prebiotic corn fiber and bone well being
Relating to dietary fiber on the whole – a nutrient of concern within the US, the place >90% of women and 97% of men do not meet recommended intakes – transferring the dialog away from ‘roughage’ and ‘regularity’ to a extra nuanced dialog concerning the microbiome has helped renew shopper curiosity in fiber, though the take-home message, as with every thing, just isn’t fairly so simple as it appears, stated Kaczmarczyk, noting that, “Not not all fibers are prebiotics, and never all prebiotics are fibers.”
For PROMITOR, having the ability to market it as a prebiotic fiber that helps bone well being has additionally pushed latest curiosity and given meals formulators on this well being profit an alternative choice past calcium and vitamin D, she added.
“In human medical research, now we have demonstrated elevated calcium absorption throughout adolescence, a very essential time for bone progress, but in addition in postmenopausal ladies, the place soluble corn fiber may also help with bone calcium retention throughout that second essential interval for bone well being when ladies have a tendency to begin dropping calcium.”
So what is the mechanism of motion?
“It might be a number of mechanisms,” speculated Kaczmarczyk. “It is tied to the prebiotic portion, so by growing favorable micro organism, these micro organism produce quick chain fatty acids, which might decrease the intestine pH, which in flip will increase calcium absorption. Additionally by altering the micro organism profile, it might change the options of the gut, growing floor space, so extra calcium may be absorbed.”
Fibers… and unsightly uncomfortable side effects?
Relating to digestive tolerance, one notably enticing factor about PROMITOR is that it’s digested extra slowly than another prebiotic fibers in the marketplace, she claimed.
“So a few of them might be digested quite shortly within the ascending colon, which means that the gases and different substances should journey fairly an extended solution to be expelled and have extra time to trigger some misery. Soluble corn fiber is fermented later, extra within the transverse and descending a part of the colon, extra slowly, and due to this fact we see fewer [GI] signs.”

THE FIBER GAP: In keeping with Kaczmarczyk: “The problem that exists right now is that customers are simply not getting sufficient fiber. Trying on the bar chart, you may see that every one the international locations’ common intakes are under the dotted line, which is the really helpful quantity we should always eat – that is the vary of suggestions from 25g/day for grownup ladies to 38g/day for grownup males based mostly on analysis demonstrating safety in opposition to coronary coronary heart illness. That is what we name the fiber hole: the distinction between what’s really helpful and what’s really consumed.”
A latest modeling research by Tate & Lyle checked out what UK customers ate through the Nationwide Food plan and Vitamin Survey, after which utilized a statistical modeling situation to see how such a eating regimen that had been reformulated with extra fiber would possibly influence well being, stated Kaczmarczyk.
“High line,” she stated, “the research discovered that 6% of the inhabitants would obtain a weight discount and 72% of the inhabitants would obtain a discount within the threat of heart problems and sort 2 diabetes.”
