I'm kind of kidding. I can't be the only person who has put a smoothie in their chamber vacuum to pull out excess air. And I KNOW that I'm not the only one who has put a fluid gel into a chamber vacuum to get the air out added by blending.
But as far as the supposed health or nutritional benefits of vacuum blending vs ordinary blending go.... I'm going to file those claims under "Snake Oil."
FWIW, if I was going to get a vacuum blender, the Tribest would be my choice. But that ain't never going to happen because this is a stupid product category.
