Do we really need high speed blenders?

Blending foods, in particular greens breaks down the cell wall of the plant and makes the nutrient more "bioavailable." The reason you would buy an expensive high powered blender is to make things silky smooth and for the durability of the machine.
How else can you access the nutrition? Chewing! Why don't we chew suffiencently? Because we are too busy running around doing other "important" things, we are too hyperactive and existing in too many places at the same time. Maybe didn't learn to chew. Beyond blending there are bigger questions. Why are we too busy to eat and digest properly? What are we doing? How do we learn to chew? What would we do if there was no more electricity? The first thing to go would be everyones inefficent iPhones. This blog would become obsolete. Maybe I should make a zine? Or hold a weekly soapbox. But what exactly is it that I have to say that is apparently important?

Cephalic phase of digestion

The process of chewing also activates signaling messages to the rest of the gastrointestinal system that triggers it to begin the entire digestive process. This is because when chewing is a well-paced, thorough process, it can actually be said to belong to the "cephalic stage of digestion", the phase in which you first see, smell and taste your food. The length of time spent chewing the food is related to the length of the cephalic stage of digestion since with more extensive chewing the longer the food gets to be seen, tasted and smelled.

Cephalic phase responses have been extensively analyzed in the research literature. The release of small messaging molecules that is critical for digestion, such as cholecystokinin, somatostatin and neurotensin, have been found to increase by over 50% just by the mere sight and smell of food. Additionally, research has shown how chewing, as well as the activation of taste receptors in the mouth, can prompt the nervous system to relay information to the gastrointestinal system to expedite the process of digestion. For example, stimulation of the taste receptors can signal the stomach lining to produce hydrochloric acid that helps in the breakdown of protein. Additionally, chewing signals the pancreas to prepare to secrete enzymes and bicarbonate into the lumen of the small intestines.

Mastication

Mastication or chewing is the process by which food is crushed and ground by teeth. It is the first step of digestion and it increases the surface area of foods to allow more efficient break down by enzymes. During the mastication process, the food is positioned between the teeth for grinding by the cheek and tongue. As chewing continues, the food is made softer and warmer, and the enzymes in saliva begin to break down carbohydrates in the food. After chewing, the food (now called a bolus) is swallowed. It enters the esophagus and via peristalsis continues on to the stomach, where the next step of digestion occurs.
Cattle and some other animals, called ruminants, chew food more than once to extract more nutrients. After the first round of chewing, this food is called cud.
The chewing cycle

Mastication is a repetitive sequence of jaw opening and closing with a profile in the vertical plane called the chewing cycle. Mastication consists of a number of chewing cycles. The human chewing cycle consists of three phases:
Opening phase: the mouth is opened and the mandible is depressed
Closing phase: the mandible is raised towards the maxilla
Occlusal or intercuspal phase: the mandible is stationary and the teeth from both upper and lower arches approximate

Mastication motor program
Mastication is primarily an unconscious act, but can be mediated by higher conscious input. The motor program for mastication is a hypothesized central nervous system function by which the complex patterns governing mastication are created and controlled.
It is thought that feedback from proprioceptive nerves in teeth and the temporomandibular joints govern the creation of neural pathways, which in turn determine duration and force of individual muscle activation (and in some cases muscle fiber groups as in the masseter and temporalis).
The motor program continuously adapts to changes in food type or occlusion.[1]
It is thought that conscious mediation is important in the limitation of parafunctional habits as most commonly, the motor program can be excessively engaged during periods of sleep and times of stress. It is also theorized that excessive input to the motor program from myofascial pain or occlusal imbalance can contribute to parafunctional habits.
