If you learn to simulate the nutrition of what the human diet has been through 99% of our evolutionary history, there is growing scientific evidence that it will alleviate obesity, diabetes, cardio-vascular diseases, arthritis, many auto-immune diseases, osteoporosis, rickets, poor health in older age, most all "chronic diseases", "diseases of civilization", asthma, acne, and more.
It sounds, and is, astounding. Think of it as the ultimate natural diet - one where you consider our long evolutionary history as a major factor of what a natural diet for the human body is ...and isn't. Our genes, physiology, and metabolic system have not had enough time to change from that of a hunter gatherer. Still existing hunters and gatherers on their traditional diets, and our hunter-gatherer ancestors, rarely, if ever, have had these health problems. Not coincidentally, wild mammals are also void of these problems - while their domestically fed counterparts are not (e.g., dogs, cats, and cattle).
The main foods that are being shown as unnatural for human digestion, or eaten in unnatural quantities, are sugars/sugar substitutes, transfats, grains/grain products, Omega 6 fatty acid rich animal foods, most industrial vegetable oils, and of course, processed foods. [Foods that comply nutritionally are detailed below; and some example meals are noted to the right.]
Through the ages there have been many hunter gatherer diets, and thus, foods you can eat. However, all are within certain nutritional constraints which we evolved on over millions of years. Our "body machinery" will only operate optimally within those nutritional constraints.
They produce specific metabolic & physiologic responses.
Some of these ancestral groups were very plant food oriented (up to 85% plant foods), but others were very animal food oriented (up to 90% animal foods). Nearly all (>95%) well-recorded groups consume at least 30% from the minor animal/plant constituent. The key point - our genes and physiology are still that of an omnivorous hunter gatherer - having changed only an infinitesimal amount from what they were when each of our ancestors ate a hunter-gatherer diet.
This website's mission is chronicling, and communicating, the converging scientific information, centered around the specific historical disciplines that are pertinent and that ultimately define the "diet". The Evolution Diet Chronicles [menu top left] are to be compiled over time as a free resource.
SHORT SUMMARY OF WHAT HISTORIC & PREHISTORIC EVIDENCES SUPPORT
DO EAT: [ eat only these - or if you can't, at least maximize them]
*Fresh vegetables [eat a variety, but not grains and legumes]
*Omega 3 rich animal foods [i.e., wild caught or free range]
*Fresh fruits [but watch total glycemic load, esp. with modern fruit juices]
BUT DON'T EAT: [ elliminate these - or if you can't, at least minimize them]
*Processed sugars, sugar substitutes
*Trans-fats, industrial vegetable oils
*Grains, grain derived products, and grain-fed, Omega 6 rich meats
*Milk & dairy products
*Legume and legume products
