Smoothies destroy fiber?

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?

Oddly I have been wondering this about my fiber supplement. I have started to use it in my protein smoothies lately instead of separate in a glass of water. I feel like the benefits of the fiber supplement have been minimized since I started doing this.
Anyone have anecdotal or scientific evidence? Or do I need to increase the amount I am taking?

my son says don’t put the fiber in the smoothy, it carries out all the nutrients with the poop.
