Evolution of the Human Diet: The Known, the Unknown, and the Unknowable by Peter S. Ungar. Diet is key to understanding the ecology and evolution of our distant ancestors and their kin, the early hominins. A study of the range of foods eaten by our progenitors underscores just how unhealthy many of our diets are today. This volume brings together authorities from disparate fields to offer new insights into the diets of our ancestors. Paleontologists, archaeologists, primatologists, nutritionists and other researchers all contribute pieces to the puzzle. The book has four sections: Reconstructed diets based on hominin fossils--tooth size, shape, structure, wear, and chemistry, mandibular biomechanics. Archaeological evidence of subsistence--stone tools and modified bones. Models of early hominin diets based on the diets of living primates--both human and non-human, paleoecology, and energetics. Nutritional analyses and their implications for evolutionary medicine.
As paleo guru Robb Wolf puts it, think of a 100-yard football field. The first 99.5 yards are how long Homo-Sapiens spent as hunter-gatherers. As they became REALLY good at hunting and gathering our bodies adapted to that lifestyle over thousands of years. That last half-yard represents our species after the agricultural revolution, where our diet has shifted (but our genetics haven’t).
Hi Janice, thank you for your comment! Certainly, many people who try the Paleo diet are able to do so while making sure that they are aqequately fueling their bodies, but I think that you’re right in saying that any type of diet can be a societally accepted way to restrict certain types of food deemed “bad” or “unhealthy” Thank you again for sharing your thoughts. Take care, Natalie
[…] I don't like the word "diet", so I'll say that this is more a way of changing what you eat long-term. It's all based around what our ancestor hunter-gatherers would have eaten, and what we've evolved to be able to process and absorb. The very basic level of it, is that you don't eat carbohydrates, processed meats or sugars, and cut out dairy products. You instead eat plenty of fresh meat, fish, vegetables, fruits and nuts. You can still have oil, provided it's natural – so coconut, peanut & olive oil are all good. The good thing is that you're also allowed to take this to your own level – so if you want a couple of days off a week – say, weekends, you can do it & it will still be a lot healthier for you. This is a really helpful site I've used to make a note on my shopping list of what's allowed: The Ultimate Paleo Diet Food List | Ultimate Paleo Guide […]
We’ve spent most of our time adapting to the food we ate before the Agricultural Revolution: animal foods, wild vegetables, fruits in season, along with limited amounts of nuts & seeds. Our bodies are built to consume these foods, but this is not what our diets look like today. Paleo is based on the idea that this mismatch between our bodies and our diet might be the reason for modern health problems like diabetes, obesity, and heart disease. Just like any other animal, humans suffer when we stray from our natural diet, but when we return to it, everything changes. Food stops making us sick, and starts making us strong, energetic, and vibrant with health. More than just a diet, it’s a lifestyle!
A Paleo dietary approach, like The Paleo Way program, generally provides greater nutrient density per calorie and is additionally extremely satisfying in smaller amounts. Both of these benefits are especially helpful for someone having had this type of surgery, as you are less likely to develop nutrient deficiencies and also less likely to eat to excessive fullness on this program. You could blend many of the recipes if need be, however once again we strongly advise that you consult your qualified and knowledgeable healthcare professional prior to commencing the program. And if doing the program having previously had gastric banding (or similar), we’d recommend you be properly monitored by your healthcare professional who is aware of your condition.
As you might expect from the previous paragraph, eating plenty of fresh fruits and vegetables naturally leads to higher fiber intake. Dietary fiber is essential for good health, and despite what you’ve probably heard, whole grains aren’t the place to find it. Non-starchy vegetables contain eight times more fiber than whole grains and 31 times more fiber than refined grains. Even fruits contain twice as much fiber as whole grains and seven times more fiber than refined grains!
The Hiwi gather and hunt a diverse group of plants and animals from the savannas, forests, rivers and swamps. Their main sources of meat are capybara, collared peccary, deer, anteater, armadillo, and feral cattle, numerous species of fish, and at least some turtle species. Less commonly consumed animals include iguanas and savanna lizards, wild rabbits, and many birds. Not exactly the kind of meat Paleo dieters and others in urban areas can easily obtain.
On his website, Sisson writes that "while the world has changed in innumerable ways in the last 10,000 years (for better and worse), the human genome has changed very little and thus only thrives under similar conditions." This is simply not true. In fact, this reasoning misconstrues how evolution works. If humans and other organisms could only thrive in circumstances similar to the ones their predecessors lived in, life would not have lasted very long.
Fresh fruits and vegetables naturally contain between five and 10 times more potassium than sodium, and Stone Age bodies were well-adapted to this ratio. Potassium is necessary for the heart, kidneys, and other organs to work properly. Low potassium is associated with high blood pressure, heart disease, and stroke — the same problems linked to excessive dietary sodium. Today, the average American consumes about twice as much sodium as potassium! Following a Paleolithic diet helps to remedy this imbalance.
NeanderThin: Eat Like a Caveman to Achieve a Lean, Strong, Healthy Body (Hardcover) by Ray Audette, with Troy Gilchrist, was one of the early paleo diet authors. His home page NeanderThin [now restored from archive.org] has a diet based on the ideas of paleolithic nutrition. The diet can be followed as a low-carb, moderate or high carb diet, depending upon whether and how much fruit is used. You can read up through page 19 of the book at Google Books.
