A plant-based diet (one rich in fruits and vegetables) contains a large amount of cellulose. Humans do not have the enzyme capable of breaking down cellulose,so we cannot utilize cellulose as an energy source. If we eat cellulose-rich, raw greens without thoroughly masticating them, we lose much of the food value. To get as many nutrients as possible into your bloodstream, the plant walls must be broken open to release the nutrients inside the cell. When we simply chew a salad, about seventy to ninety percent of the cells are not broken open. As a result, most of the valuable nutrients contained within those cells never enter our bloodstream..........................By contrast, when you consume a blended salad, you are assuring a thorough digestion of the plant protein. Ninety- eight percent of all the proteins will be broken down into amino acids or very small peptides, and absorption will be almost complete as well. As a result, you absorb almost all the protein in the raw greens, instead of losing so much..
