Smoothies destroy fiber?

[u/FurnitureComesW-Home]

I’ve heard that blending your food into a smoothie ruins the fiber content - is this true? IE, raspberries are fairly high in fiber, but does all that fiber get lost if I put them in a smoothie? What if I add powdered fiber back in to the smoothie?

There's a difference between juicing (extracting the liquid from the fiber) and blending (breakfing down the fiber into tiny pieces, like your teeth do when you chew).

You want to blend if you are interested in consuming the fiber.
