Paleo Diet: the Myth of a Thriwing Caveman
In this world of processed foods that give us diabetes and heart disease, wouldn't it be better to go back to the original diet of our ancestors who roamed the plains and hunted mammoths? Paleo diet is based on very romantic notions. Are they based on good science?

- The theory goes that our genome hasn’t changed since the Paleolith: we are ill-adapted to eating grains etc. and don’t digest these foods well;
- The root of prevailing obesity, atherosclerosis and other modern chronic diseases lies in the food that we eat: presumably, our ancestors were much healthier;
- Modern humans consume far too much sodium (which, as many studies show, leads to hypertension) and sugar, while nitrates in processed meats are linked to cancer.
What’s wrong with Paleo?
Evolutionary biologists find many issues with the paleo diet, ranging from possible health risks to pure illusions about how our cave ancestors lived. It is simply not true that our genetic code has not evolved in the past 10 000 years; we now produce lactase all our life, which allows us to digest dairy; plus, our intestinal flora evolved with us to help us digest whatever we eat (more info on ancient nutrition here). It is not known precisely what and how much our ancestors ate; however, they surely started eating grains long before they started cultivating them, and dairy production can be as old as 7500 years. Modern meat, chicken, and vegetables are nothing like their wild ancestors: animals were skinny, apples sour, and bananas full of seeds. A true caveman diet is simply impossible. Paleolithic people were not necessarily healthy: analysis of human remains shows that, apart from generally dying before the age of 30, our ancestors suffered from atherosclerosis, parasites, and a variety of bacterial diseases. Finally, eating too much meat can be detrimental for your health; and cutting out dairy – the main source of calcium – and legumes (a great source of protein) is not wise, either.In conclusion: our Paleolithic ancestors were hightly adaptive omnivores, who survived on whatever they could find, and so are we. Sure, modern diet is far from perfect. But the things to cut out are not potatoes and yogurt, but rather artificial packaged foods that do not benefit us in any way.
