There’s a fibre source that isn’t talked about much but in my opinion is one of the better ones out there.
PHGG (Partially Hydrolised Guar Gum) it’s great for multiple reasons it’s got all the hallmarks of fibre, it’s gentle on the gut unlike others, won’t cause bloating, it’s a bit of a wonder fibre that it will firm things if too soft, and soften things up if too firm… it’s largely tasteless, dissolves away to nothing in water which makes it great for adding to a smoothy or spiking your favourite goto meals with some fibre goodness, adds a great silky texture to gravies or sauces.
Highly recommend as a cupboard staple.
