Modern human diet from an evolutionary aspect

To understand the optimal diet for human, a new line of research says human nutrition has to be examined from an evolutionary perspective. Human digestive and hormonal systems evolve very slowly.  The human diet has has adapted to a nutritional environment around the Miocen period.

Changes of the nutritional environment, adding a new nutritional component or the change in the availability of major nutritional components like proteins, carbohydrates, etc. can require adaptation of the human digestive, hormonal and/or metabolic system.

This adaptation process is quite slow, lasting from thousands to millions of years, depending on the extent of the change in the nutritional environment. Because adaptation is such a slow process, major changes in the nutritional environment ( which is the case in our century) can cause serious health problems.

Modern, evolution based nutrition has the challenge of finding out what our ancestors diet looked like and which components of our modern diet do not correspond with that original diet.

This is an intensive research area with a lot of knowledge but also with a lot of unanswered questions. I would like to introduce you this new, but intense research area and share with you some interesting and sometimes rather confusing facts about healthy diet in the next few blogs.

Here are some topics we will cover:

  • What are the major components of our ancestor’s diets?
  • What is GI and why is it important?
  • How much protein and carbohydrate do we need? Are we vegetarians or predators?
  • Is fat is bad for us?
  • About fish and other seafood.
  • What is omega3 and omega6 and why are they so important?
  • About chronic, low level inflammation..
  • About sugar what is the problem with it?
  • What lectins are and are there any problems with them?
  • Is grains an important part of our diets?
  • What about diary?

 I hope you will share your questions about these topics and that those questions will be answered!
