While a complicated smoothie adds such a nice diversity of nutrients for your body, our favorite still these days is keeping it simple: Kale and pineapple. Done in minutes. Oh yeah I add 1 tbl flax seed. And I can say here I am using a can of pineapple; this can get it sweet enough for our picky four year old to enjoy or more bitter if I add more kale. Either way I can put tons of kale (because of the immense countering sweetness of the pineapple). There is only so much room in a blender and I cram it mostly full of greens (Kale or swiss chard or collards all work well).
A high speed blender will spin the nutrients right out of those plant cell walls and make more accessible all those valuable nutrients. You nearly always add about a cup of water to the bottom of a high speed blender to blend; then pulse a few times and for my Blendtec/K-Tech I hit number 2 (which is a programed blend setting that runs through a cycle that finishes). I have destroyed many average blenders quickly. My Blendtec has paid for itself. I have been using it heavily for about 5 years now and still without a single problem. IT IS SO EASY TO CLEAN. Two pieces, the lid and the jar, done. There are no little parts. Also it is shorter than the vitamix so it slides under the cabinets easily. You could blend a cell phone into dust in that thing. Now when I make almond milk there is no left over almond powder/parts – everything is blended into milk and very fast.
For me the Blendtec blender is the most important plug-in tool in the kitchen. And we have a nice cuisinart (food processor) and a great juicer (also easy to clean; it is a Samson). A great blender is by far the most important tool for us. If you interested in getting any of these, in my opinion, start with the high-speed blender, next important for me is the juicer.
Enjoy drinking your green smoothie made so easily. The green smoothie is fine on the go or on the seat. Enjoy taking care of yourself. You really are worth it!
