Check out our first in a series of videos we’ve created to give you an update on the science of the Paleo Diet and what’s going on at thepaleodiet.com, including some exciting changes in the upcoming months. In this episode, Dr Cordain talks about what’s currently happening at The Paleo Diet® and then he goes into what you can expect next:
Hormones in Milk Excerpt
Because people co-evolved with their environmental food sources, the human genetic make-up was shaped throughout millions of years of relying on relatively homogenous nutrition. Many foods, new to the human genome, were rapidly introduced following the Agricultural Revolution. So many, in fact, that approximately 70% of the typical Western diet now comes from food sources that were rarely, if ever, consumed by our Stone-Age or Paleolithic ancestors.
One of the many problems that have been seen to arise along with our change in diet is acne. By focusing on the foods our Paleolithic ancestors ate for millions of years, the Paleo Diet provides all the necessary micronutrients, including calcium, to fuel health and fitness. The Paleo Diet also avoids the risks of many diseases linked to the consumption of many of the foods more recently assailing the human genome.

Insulin, Betacellulin, and Estrogens Excerpt
We discovered that bovine insulin (BI) is present in commercially pasteurized milk and infant formulas. We also learned that BI has good oral bioavailability since antibodies to BI are a common phenomenon among children who have consumed infant formula containing cow’s milk. This is very important information for children who have a genetic predisposition for T1D because BI differs from human insulin by only three amino acids. The immune response induced by BI in these children may react with human insulin and lead to ß-cell destruction, especially if children are exposed to infant formula containing cow’s milk before the age of 3 months. This is a period of high intestinal permeability or leaky gut.
As expected, various epidemiological studies have associated cow’s milk consumption with T1D in genetically susceptible children, especially when the initial exposure begins in the first months of life. Thus, exclusively breastfeeding during the first 6 months and avoiding formulas based on cow’s milk is highly recommended.

How to be Acne Free Excerpt
Most people think that acne is a disease of adolescence that just disappears after the teen years. Not so! In the United States, acne affects between 40 and 50 million people from children to adults. In young adults, some degree of facial acne is found in 54% of women and 40% of men. Those suffering from acne are estimated to spend millions collectively each year on over-the counter acne treatments.
Surprisingly, the causes of acne have been known for more than 40 years. Acne develops from four processes:
1. Blockage of the follicle opening or the pore
2. Excessive production of skin oil
3. Bacterial colonization and infection of the pimple and
4. Inflammation of the pimple and surrounding tissue
Let’s take a look at how diet influences the development of acne.

Paradigm Shifts, Historical Sciences and The Paleo Diet
Most readers know that the word, “Paleo” is short for “Paleolithic”. As a prehistoric time, the Paleolithic is important because it covers over 99% of human history. It began approximately 2.5 million years ago,1 with our first stone tool using ancestors, and ended approximately 10,000 years ago (exact time varied with culture and geography) with the advent of mass agriculture and its foodstuffs.
So, across the globe, our ancestors lived more than 2.4 million of the last 2.5 million years as huntergatherers. Hunter-gatherer type diets (like the Paleo Diet) are defined by this evolutionary template2 that humans evolved to eat over this vast amount of prehistoric time. As what now must be considered a new paradigm in health science, Paleolithic nutrition sets forth the idea that our genetically determined biology from the distant past plays a major role in determining the nutrition for optimizing health.

Pregnancy, Infants, and The Paleo Diet
With the growing popularity of the Paleo Diet, we’ve received questions about adapting this diet for pregnancy, particularly with regard to the low fat aspect of the diet. Others are also asking for more information about adapting the Paleo Diet to the growth and nutritional needs of infants and young children. With a little modification, the Paleo Diet can meet these needs, help children escape the growing childhood obesity problem, build life-long eating habits to lower the risk of disease, and generate healthful, vital longevity. Here are some recommendations for using the Paleo Diet to optimize nutrition during pregnancy, infancy and childhood.

Prader-Willi Syndrome Beaten by Paleo
One of the symptoms of Prader-Willi Syndrome (PWS) is a chronic feeling of hunger that can lead to excessive eating and life-threatening obesity, according to the USA Prader-Willi Syndrome Association. The association reports that one in 12,000 to 15,000 people are estimated to have PWS, and it is the most common identified genetic cause of obesity.
Long-term consumption of high glycemic-load foods has been associated with increased risk of obesity. By emphasizing low glycemic-load foods, the Paleo Diet helps to optimize body weight. The correct balance of carbohydrate, protein and fat that the diet provides also improves blood-lipid profiles, helps you to feel fuller, and enables you to burn more calories.

Keratoconus Eye Disorder Excerpt
Keratoconus is a degenerative eye disorder involving structural changes within the cornea that can cause visual distortions, such as multiple images, streaking and light sensitivity.
I believe that keratoconus would have been rare or non-existent among our pre-agricultural ancestors simply because if it were entirely a genetic maladaptation, it would have been rapidly eliminated by natural selection.
Given the incidence of keratoconus in Western populations, it seems likely that environmental factors introduced since the advent of agriculture may trigger this disease. Clearly diet and sunlight exposure (vitamin D) have to be implicated.

Nucleotides and The Paleo Diet Excerpt
Nucleotides are small molecules that are the building blocks of DNA and RNA. They are composed of a nitrogen-containing base bonded to a sugar and one or more phosphate groups. They occur in all foods of animal or vegetable origin as free nucleotides or nucleic acids. Their concentration depends on cell density, which explains why organ meats are such a rich source.
Traditionally, nutritionists have dismissed any dietary need for nucleotides arguing that the body can produce them itself. This view has begun to change over the last two decades as a mounting body of research has demonstrated that dietary sources of them play several key roles.One hint to the larger story is that the preponderance of foods with high concentrations of nucleotides are Paleo foodstuffs, such as game, organ meats (heart, liver, spleen, lungs and sweetbreads) and whole fish.

Paleolithic Diet is the Best Bet for Diabetes Excerpt
A newly published study in Cardiovascular Diabetology compared the effects of a Paleolithic diet to the current guidelines for a diabetes diet, and looked at cardiovascular risk factors for type 2 diabetes patients. The participating three women and ten men, who had type 2 diabetes that was not treated with insulin, were instructed to follow each diet for three-months.
The Paleolithic diet used was lower in cereals and dairy products, and higher in fruits, vegetables, meat and eggs. It was also higher in unsaturated fatty acids, dietary cholesterol and several vitamins. It was lower in total energy, energy density, carbohydrate, dietary glycemic load (GL) and glycemic index (GI), saturated fatty acids and calcium.
