The Paleo diet is built on the idea of eating the foods our bodies were designed for throughout thousands of years of evolution. The readily available foods were eaten by the hunting and gathering of meat and fish, nuts and seeds, fruits and vegetables.
During modern times, the times we live in now, advances in technology have made other forms of food available for consumption such as grains, dairy, and processed foods, which are below the optimal forms of nutrition. The foods recommended by the Paleo diet provide our bodies with long-lasting energy that also aid in burning fat cells.
To explain a little more in detail, here’s a little Paleolithic timeline for you. We started eating the Paleo way about 2.5 million years ago, and then we drastically changed our diets about 10,000 years ago when we began cultivating grains and legumes. That’s not much time for evolution to catch up with us, meaning our bodies are still most adept at eating the way we used to eat: meat, vegetables, fruits, and some nuts and seeds.
When I say not a lot of time, think of it like this: 10,000 years out of 2.5 million is equivalent to a little under 2 months of a 40 year old man’s life, or .4% of his life – not very much. Switching from our evolutionary diet of animal products, veggies and fruit to a diet full of grains and legumes is like that movie Super Size Me where Morgan Spurlock goes from eating his normal diet to eating only McDonald’s food for 30 days. His health plummets – he gets fat and depressed, and he develops fatty liver and sexual dysfunction.
That’s basically what’s happened on a grand scale over the last 10,000 years of humanity. We have replaced wholesome, clean plant matter and animal foods with a high carbohydrate, low nutrient, high toxic chemical diet and we’ve gotten sick. We have shrunken in size, our bones are osteoporotic, we have more cancer, obesity and diabetes, an alarming incidence of heart disease, inflammation of all kinds, skin problems and the list goes on. And on. We are sick. But our Paleolithic ancestors were not and the hunter gatherer tribes that still exist are not.
