Added fibre is real fibre. It does not become fake because it was separated from a plant or used as a food ingredient. Judge it by what it does and the evidence behind it. A natural sounding name is not a test of how good it is.
Whole foods and added fibres serve different roles. Both deserve credit for the work they actually do.
Check the specific fibre
Some fibres hold water. Some form a gel. Others are broken down by gut microbes. These properties explain why different fibres have different effects. [1]
Research on fibre supplements found that certain fibres, including psyllium, improved constipation outcomes. That is direct evidence that a separated fibre has useful effects. [2]
It does not prove every added fibre has the same benefit. Match the finding to the ingredient. Food science is useful enough without pretending all of its tools are identical.
Understand the prebiotic claim
Some added fibres also qualify as prebiotics. That means microbes selectively use them and this brings a proven health benefit. Being added to a food does not disqualify them. [3]
But simply feeding bacteria does not prove that a fibre meets the full definition. Ask what benefit was shown and at what dose.
That is a better test than praising anything that says gut friendly. The phrase takes very little space on a wrapper. The evidence takes more work.
Use each food for its role
Beans, vegetables and fruit provide fibre along with their wider food package. A bar with added fibre does not replace all of that. It is an easy way to add some fibre.
This is the point of a functional ingredient. It adds a chosen property to a food where that property is useful. We do not ask milk protein to become a whole meal either.
FEERO's brief allows soluble fibre ingredients to help build the bar. Read our guides to soluble corn fibre and polydextrose for their specific roles.
Choose the fibre for the job, check the amount and assess comfort. Rejecting it because it came through a factory is not a scientific argument. Neither is claiming it fixes every gut problem. Useful ingredients deserve clear explanations.
