I consume two meals of Huel a day with extra oat bran powder. One meal is blended with a Nutribullet and one is just mixed in a shaker. I was recently having a discussion about fibre nutrition with a friend who posed the following questions:
Since Huel is a powder, does the powdering process not cut the long fibre molecules and turn it into carbs?
If you are blending said powder into a smoothy, does this not cut the fibre as above?
I am aware that this is probably not an issue for soluble fibre, but can someone offer some (evidence based) advice on how this affects insoluble fibre (which I believe are the long fibre molecules my friend was talking about)? I have tried internet stuff and predictably have got lots of conflicting opinions and little science.
Blending does not destroy anything - merely changes its state slightly. You are not applying enough energy to cause a significant change. Blending may affect fibre activity in the body as it can reduce its ability to hold water, but that’s about it. This would have to be a very powerful blender that has completely liquefied everything however.
I think many people confuse this with juicing which clearly does reduce or remove much of the fibre content.
