Yes I do at times. However, I consider it less than optimal. I enjoy eating my food as is. I enjoy eating with my hands, picking up a new fruit, peeling it, handling it, and finally chewing it! When we process our food before eating it, it becomes something else and is no longer food, in the strictest sense of the word.
When we blend something we oxidize nutrients, we damage the food and it loses some of its integrity. Blending can also “help us” eat something we otherwise wouldn’t like by mixing it with a fruit we like and thus masking the taste of whatever it is we are trying to “sneak into” our bodies, be it a green powder, a bitter herb or some other non-food item. It’s also easy to just gulp down the whole thing without chewing, and chewing is actually an important stage of digestion where the food is mixed with enzymes and the body prepared to deal with it.
If we have to do something to the food to make it palatable, I would question the value of that item as a natural food for humans in the first place.
All this being said, is a smoothie evil? No, but it’s not ideal! What about food processing something, dehydrating something and making some kind of fancy gourmet dish? Well, if you want to have some fun it the kitchen, just like you used to do “back in the day”, then go ahead, experiment, see what works and what doesn’t, life is full of small compromises. Just remember, for optimal health; eat food with as little processing done to it as possible, in its natural state, raw, whole and as nature intended. This is not only healthier, but far more enjoyable once you get used to it.
