The evolution of mankind from the stone ages till now has also shown a remarkable change in diet. With the coming of humans developing larger brains, they had evolved to consume grains, cooked meat, starches, and many more. With this time and age we have been able to mass produce food and changed from this hunter gatherer society into one of factories of farms. However it seems the food that we consume now comes with a heavy toll compared to our ancestors. Diseases that were not known to our ancestors such as diabetes, hypertension, and heart diseases have appeared in our current age. This led people to search for a healthier alternative to what we consume mass produced.
The food and lifestyle that earlier humans had consumed seemed to be mostly hunting for meat and from this came to the popularity of the Paleo diet where the diet tired to mimic the diet of earlier humans. The search for a healthier diet from our predecessors is a good way to find a more balanced diet for humans in general. However if leading a similar diet we must also lead a similar lifestyle of exercises and also start limiting the amount of meat, fat, and starch we consume.
