“Blending, however, does chop fiber into smaller pieces. How this affects its activity in the body depends on what kind of fiber we’re talking about. An article Lee dug up for me in The Journal of Food Science notes that grinding up wheat bran reduces its ability to hold water, which presumably decreases its effectiveness in promoting regularity. In fact, one study found that supplementing the diet with very finely ground wheat bran actually caused constipation!
Oat bran on the other hand soaks up more water when you reduce the particle size. There’s also some research suggesting that grinding up vegetable fiber into smaller pieces makes it more effective in reducing cholesterol.
So, I don’t know that we can say that blending “destroys” fiber. But we can certainly conclude that blending “changes” fiber in foods and how they affect the body. Based on my brief tour through the literature, I think I would avoid putting wheat bran in my smoothie. Flax seed, on the other hand, is really only useful as a source of fiber if you grind it (or chew it up really well). Coarsely ground flax appears to be slightly more effective than finely ground flax…so don’t overdo it.

I’m afraid there’s no simple answer. Blending or juicing foods can make certain nutrients more absorbable. It may decrease the effectiveness of some fibers but increase the effectiveness of others. Honestly, I think this falls into the (rather large) category of things that probably aren’t worth worrying about.” (sursa afirmațiilor e discutabilă, dar aproape fiecare afirmație din articol e pe bază de studii; ai în articol multe surse »)
How to save lots of money on big purchases?
TL;DR: So, if you plan to buy something of high value: Have patience. Do price comparisons. Do research. Visit at least two places. Consider being aggressive in negotiations. Through surveying more than 1,400 car buyers, Silva-Risso and his co-authors, Fiona Scott Morton, of Yale University, and Florian Zettelmeyer, of Northwestern University, found buyers could save about $800 if they find out what a dealer pays for a car, visit two dealerships, like to bargain and like to do research and price comparisons before making a purchase. The research also found that a consumer who doesn’t like to bargain or do a lot of research can save $230 by doing just two things: finding out what the dealer pays for the car and visiting two dealerships. “This really shows that even the consumer who doesn’t like to bargain can get the price reduced if they are informed,” Silva-Risso said. “And, if they are aggressive, and like bargaining, they can save even more.
