ABSTRACT

There is growing awareness that the profound changes in the environment
(e.g., in diet and other lifestyle conditions) that began with the
introduction of agriculture and animal husbandry approximately 10,000 years
ago occurred too recently on an evolutionary timescale for the human genome
to adjust.  In conjunction with this discordance between our ancient,
genetically determined biology and the nutritional, cultural and activity
patterns of contemporary western populations, many of the so-called diseases
of civilization have emerged.  In particular, food staples and food
processing procedures introduced during the Neolithic and Industrial Periods
have fundamentally altered seven crucial nutritional characteristics of
ancestral hominin diets: 1) glycemic load, 2) fatty acid composition, 3)
macronutrient composition, 4) micronutrient density, 5) acid/base balance,
6) sodium/potassium ratio, and 7) fiber content.  The evolutionary collision
of our ancient genome with the nutritional qualities of recently introduced
foods may underlie many of the chronic diseases of western civilization.
