Last night I watched the movie Fat, Sick, and Nearly Dead. The movie followed two unhealthy people who suffered from a chronic disease on their juice fasts and subsequent lifestyle changes. Their health improved dramatically, their disease was cured, and they both lost tons of weight.
Part of the goal of the movie seems to be to encourage the movie's viewers to go on a juice fast which they called a Reboot. The Reboot Juice Fast FAQ on the movie's website makes a bunch of vague claims about cleansing and toxins, but the claim I'm most interested in is stated in the first question:
Can I live with no protein for the duration?
When we cleanse, the main goal is to unravel and release as much toxic burden from the body as possible. In fact, most of us have undigested proteins stuck in our tissues and cells from years of ingesting certain foods. In terms of protein, what we are really looking for are the amino acids, or building blocks of protein which reside in everything: green leafy vegetables, fruit, sprouts, other vegetables, nuts, seeds, coconut, avocado, whole grains, beans, legumes. So even when you are not cleansing, it is virtually impossible to become protein deficient. However, while on the cleanse, we do not need to concern ourselves with this aspect, as again we really want to unload the undigested proteins which are sitting in the system.
Having undigested protein from "certain foods" (which foods?) doesn't seem to fit what I know about human biology.
So, do most (or at least some) humans have undigested protein in their bodies?
