Lessons From Ötzi, the Tyrolean Ice Man. Part II

Otzi's Diet

Otzi's digestive tract contains the remains of three meals.  They were composed of cooked grains (wheat bread and wheat grains), meat, roots, fruit and seeds (1, 2).  The meat came from three different animals-- chamois, red deer and ibex.  The "wheat" was actually not what we would think of as modern wheat, but an ancestral variety called einkorn.

Isotope analysis indicates that Otzi's habitual diet was primarily centered around plant foods, likely heavily dependent on grains but also incorporating a variety of other plants (3).  He died in the spring with a belly full of einkorn wheat.  Since wheat is harvested in the fall, this suggests that his culture stored grain and was dependent on it for most if not all of the year.  However, he also clearly ate meat and used leather made from his prey.  Researchers are still debating the quantity of meat in his diet, but it was probably secondary to grains and other plant foods. It isn't known whether or not he consumed dairy.

Paleo Diet Article in Sound Consumer

I recently wrote an article for my local natural foods grocery store, PCC, about the "Paleolithic" diet.  You can read it online here.  I explain the basic rationale for Paleo diets, some of the scientific support behind it, and how it can be helpful for people with certain health problems.  I focused in particular on the research of Dr. Staffan Lindeberg at the University of Lund, who has studied non-industrial populations using modern medical techniques and also conducted clinical diet trials using the Paleo diet.

Junk Free January

Last year, Matt Lentzner organized a project called Gluten Free January, in which 546 people from around the world gave up gluten for one month.  The results were striking: a surprisingly large proportion of participants lost weight, experienced improved energy, better digestion and other benefits (1, 2).  This January, Lentzner organized a similar project called Junk Free January.  Participants can choose between four different diet styles:
  1. Gluten free
  2. Seed oil free (soybean, sunflower, corn oil, etc.)
  3. Sugar free
  4. Gluten, seed oil and sugar free
Wheat, seed oils and added sugar are three factors that, in my opinion, are probably linked to the modern "diseases of affluence" such as obesity, diabetes and coronary heart disease.  This is particularly true if the wheat is eaten in the form of white flour products, and the seed oils are industrially refined and used in high-heat cooking applications.

If you've been waiting for an excuse to improve your diet, why not join Junk Free January?
