I'll have the roast duck with the mango salsa.

The Paleolithic Diet and Its Modern Implications
An Interview with Loren Cordain, PhD
by Robert Crayhon, MS

Can hundreds of thousands of years of human evolution be wrong? What are we really "designed" to eat? Are high carbohydrate "Food Pyramid" diet standards a health disaster? What do paleolithic fossil records and ethnographic studies of 180 hunter/gatherer groups around the world suggest as the ideal human diet? Find out in nationally acclaimed author and nutritionist Robert Crayhon's interview with paleolithic diet expert, Professor Loren Cordain, Ph.D.
Robert Crayhon, M.S. is a clinician, researcher and educator who was called "one of the top ten nutritionists in the country" by Self magazine (August 1993). An associate editor of Total Health magazine, he is the author of best-seller Robert Crayhon's Nutrition Made Simple and the just published The Carnitine Miracle (M. Evans and Company).
Dr. Loren Cordain is a professor of exercise physiology at Colorado State University in Ft. Collins, Colorado, and is a reknowned expert in the area of Paleolithic nutrition.
Robert Crayhon: I'm very happy to welcome Dr. Loren Cordain. He is a professor of exercise physiology at Colorado State University in Ft. Collins, Colorado, and an expert in the area of Paleolithic nutrition. Dr. Cordain, welcome.
Loren Cordain: My pleasure to be here.
Robert Crayhon: There has been in the past 40 years or so much interest in the area of low fat diets, and it seems that the media and USDA with its food guide pyramid is now convinced that a healthy diet is one that is predominantly carbohydrate, low in fat and protein. There is also little regard for the quality of the fat or protein. But are we really just in some great agricultural experiment? Has the last 10,000 years of agriculture really been the bulk of what the human nutritional experience has been? And is this grain-based, high carbohydrate diet truly ideal for humans?
Loren Cordain: There is increasing evidence to indicate that the type of diet recommended in the USDA's food pyramid is discordant with the type of diet humans evolved with over eons of evolutionary experience. Additionally, it is increasingly being recognized that the "food Pyramid" may have a number of serious nutritional omissions. For instance, it does not specify which types of fats should be consumed. The western diet is overburdened not only by saturated fats, but there is an imbalance in the type of polyunsaturated fats we eat. We consume too many Omega-6 fats and not enough Omega-3 fats. The Omega-6/Omega-3 ratio in western diets averages about 12:1, whereas data from our recent publication (Eaton SB, Eaton SB 3rd, Sinclair AJ, Cordain L, Mann NJ Dietary intake of long-chain polyunsaturated fatty acids during the Paleolithic Period. World Rev Nutr Diet 1998; 12-23) suggests that for most of humanity's existence, prior to agriculture, the Omega-6/Omega-3 ratio would have ranged from 1:1 to 3:1. High dietary Omega-6/Omega-3 ratios are associated with increased risk for cardiovascular disease, some types of cancer, and tend to exacerbate many inflammatory disease responses.
Further, the USDA food pyramid places breads, cereals, rice and pasta at its base and recommends that we consume 6-11 servings of these items daily. Nutritionists at the Harvard School of Public Health (Willett WC. The dietary pyramid: does the foundation need repair? Am J Clin Nutr. 1998;68: 218-219) have recently publicly criticized this recommendation because it fails to distinguish between refined and complex carbohydrates and their relative glycemic responses. Dr. Willett further pointed out that there was little empirical evidence to support the dominant nutritional message that diets high in complex carbohydrate promote good health.
Both the fossil record and ethnological studies of hunter-gatherers (the closest surrogates we have to stone age humans) indicate that humans rarely if ever ate cereal grains nor did they eat diets high in carbohydrates. Because cereal grains are virtually indigestible by the human gastrointestinal tract without milling (grinding) and cooking, the appearance of grinding stones in the fossil record generally heralds the inclusion of grains in the diet. The first appearance of milling stones was in the Middle East roughly 10-15,000 years ago. These early milling stones were likely used to grind wild wheat which grew naturally in certain areas of the Middle East. Wheat was first domesticated in the Middle East about 10,000 years ago and slowly spread to Europe by about 5,000 years ago. Rice was domesticated approximately 7,000 years ago in SE Asia, India and China, and maize (corn) was domesticated in Mexico and Central America roughly 7,000 years ago.
Consequently, diets high in carbohydrate derived from cereal grains were not part of the human evolutionary experience until only quite recent times. Because the human genome has changed relatively little in the past 40,000 years since the appearance of behaviorally modern humans, our nutritional requirements remain almost identical to those requirements which were originally selected for stone age humans living before the advent of agriculture.
Robert Crayhon: What happened to our health when we switched from a hunter-gatherer diet to a grain-based one?
Loren Cordain: The fossil record indicates that early farmers, compared to their hunter-gatherer predecessors had a characteristic reduction in stature, an increase in infant mortality, a reduction in life span, an increased incidence of infectious diseases, an increase in iron deficiency anemia, an increased incidence of osteomalacia, porotic hyperostosis and other bone mineral disorders and an increase in the number of dental caries and enamel defects. Early agriculture did not bring about increases in health, but rather the opposite. It has only been in the past 100 years or so with the advent of high tech, mechanized farming and animal husbandry that the trend has changed.

A ping for your interest...old thread that just reappeared.
They also have very low incidents of digestive system cancer. Obviously this could be due to other factors but I've always wondered if we were designed to eat meat why our intestines weren't designed like those of other meat eaters.
We are not pure carnivores (like cats), but rather omnivores (like bears, pigs, rats, dogs).
Carolyn
Eat like cave men and women.
As long as we get the same amount of exercise and fast for a few days every few weeks.
I do think the newest food pyramid is more PC than healthy. Sorry, fed - I would make a really lousy vegetarian.
You might want to visit Dr. Mercola's site and do a search on conjugated linoleic acid (CLA).
Bump.
Government, in the fullness of time, inflicted swarms of liberals upon us, eating out our substance. If it weren't for Free Republic, we'd all be wearing chains and picking cotton. So send Jim some money -- y'hear?
Thanks, I like it when that happens.
This is the ancient Munro diet. Eliminate carbs altogether. Bugs and berries okay.
I don't know the Munro diet, but I do know a bit about this one. It is based on pretty extensive data regarding the diets of hunting-gathering persons from all over the world (these people's diets would be closest to that of our ancestral hunter-gatherers) so, it has that.
Munro or Monroe I read about maybe 35 years ago and the book was old then. Said we were carnivores, and furthermore used to live very long lives. When our ancestors began agriculture and eating wheat, etc, our lifetimes were reduced to what they are now. Kind of questionable, but Munro said eat all the meat, eggs you want, avoid everything with starch. Orange juice okay. I would not recommend this, just reporting.
Mine sounds like an updating of Munro's point of view with more data to back it up. But Munro's basic point was, and remains, correct.
When I eliminate the bad stuff from ER4YT and follow an Atkins low carb diet, I can lose weight and stay exceptionally healthy. A little regular exercise helps a bunch. Russian kettlebells are my exercise of choice.
