If you learn to simulate the nutrition of what the human diet has been through 99.9% of our evolutionary history, there is converging scientific evidence that it leads to a new plateau of health. There are now thousands of examples of the general nutritional protocol alleviating, or drastically diminishing: diabetes, cardiovascular disease, obesity, arthritis, rickets, progressively poorer health in older age, asthma, M.S., acne, ... and, in fact, most all labelled as "chronic diseases", "diseases of civilization", "auto-immune diseases", or "metabolic syndrome".
It seems too astounding to be true ... but the paradigm has been defined, and is backed and being continually refined, by a sizable group of cutting edge doctors, archaeologists, ethnographers, and nutrition scientists.
The latest iterations are "ancestral diets", "primal diets", "caveman diets", and now popular "paleo diets", based on copying our best interpretation of our ancestors' Paleolithic Age nutrition(i.e., Paleolithic Nutrition). As with any developing new paradigm, however, it is important that it not be treated as some fad as more detail inevitably develops. For example, E.D.I. questions whether the Paleolithic Age is the proper time constraint, for an optimal, evolution-based diet ... and also questions the highly prevalent idea within Paleolithic Nutrition, and most related paleo communities, that the optimal evolutionary nutrition for humans needs to be a meat dominant diet.
Think of it as the ultimate natural diet - one in which you consider our long evolutionary history as a major factor in determining what a natural diet for the human body is. Our genes, physiology, and metabolic system have not had enough time to change from that of our hunter gatherer ancestors. These ancestors (and still existing hunters and gatherers on their traditional diets) rarely, if ever, have had these health problems. The earliest farmers, from the Mesolithic Age, also did not. Furthermore, and not coincidentally ... wild mammals are also void of these problems - while their domestic, cereal grain-fed counterparts (e.g., dogs, cats, and cattle) ... are not.
The Human Evolution Diet is an immediately downloadable and easy to print e-book. It fully explains the emerging scientific concept of optimal human evolutionary nutrition as of 2015. Within half a day's study you can comprehend and enact this exciting nutritional paradigm. Although written to be understandable by the general public, there are many supporting technical articles by doctors and university professors included.
