As regards the diet, the period of our ancestors under consideration is essentially the Paleolithic era (hence the name of the diet) -a period lasting about 2.5 million years and which ended around 10,000 years ago with the beginning of animal domestication and Destructeur de diabète agriculture.The underlying basis for the theory is evolutionary discordance hypothesis, itself a subset of evolutionary medicine. The seeds of the hypothesis is to be found in the 1970s work of Walter Voegtlin, the gastroenterologist.Its basic premise is that man is genetically adapted to the nutritional needs of food to be found in the Paleolithic period. These needs have not changed and remained adapted to the diet of the said ancestors. Despite the availability of a wide variety of relatively new foods like legumes, grains, dairy, and high in calorie processed foods -the main stay of much of our modern day diet, human metabolism the hypothesis claims, remain maladjusted to them. The result is these foods improper breakdown and assimilation by the body, leading to the health conditions- heart disease, high blood pressure, and yes-diabetes, earlier spoken of.

The answer to this was the Paleolithic diet. One man-Loren Cordain set out to let the world know this. He wrote his book-"The Paleo Diet" in 2002, popularized the diet and in fact being so recognized as an authority on it was by 2009 able to successfully trademark the term "Paleo Diet". By the late 2000s, the diet had gained in popularity riding on the back of several steeds, namely that of an appeal to nature and efficacy.That said, the logic behind the diet has come under fire. First it has been criticized on the premise that there is no concrete evidence to show exactly what human beings ate during the Paleolithic period. Secondly, that evidence shows that Paleolithic man did in fact eat legumes and grains. Thirdly, that the surmise having humans adapted to specific local diets is unproven. Further, that humans are capable of greater nutritional flexibility than the diet gives them credit for and finally, that the Paleolithic period was an extremely lengthy period which saw human existence in different geographies offering different foods.
