For millennia, the human body was dependent on a limited
seasonal contingent of raw or semi-raw foods that could be
obtained with bare hands and in the wild—mainly fish, seafood,
and grazing animals.
Much is made of “gathering,” but it was the least efficient and
least relied upon method of sustaining life, because the
gathering of edible plants in the wild was severely limited by
the seasons (especially as humans moved up north), while fish,
seafood, and animal meats where still abundant year-round.
As human intellect, dexterity, and strength evolved, food
sources became more numerous, but they still remained relatively
small—meats, eggs, and milk from domesticated livestock, and,
until recently (in terms of human evolution), agricultural
products such as wheat, millet, and rice. Finally, courtesy of
the industrial revolution, humans learned to process
once-inedible plants, such as soy or wheat bran, into foods for
human consumption. Most present day cultivated varieties of
fruits and vegetables are also just a brief blimp—less than a
few thousand years old—on the evolutionary timeline.
Evolution was merciless. Those who mastered the art of survival
passed their genes onto us. These genes determined the makeup
and the needs of our bodies. In turn, these needs determine what
we should and shouldn’t eat. The choice wasn’t complicated even
a hundred years ago because the variety of foods was limited,
and almost all of those foods were functional—i.e. they were
fulfilling their particular function of sustaining life,
beginning with breast milk, the most functional food of all.
Not today. The majority of supermarket-style foods aren’t
functional, but simply edible. We can survive on them, but can’t
enjoy even a modicum of the health and strength possessed by the
cavemen.
Why? Because edible foods sustain life, not health. For vibrant
health the food must be functional. And that’s the subject of
the fascinating book below, which was the highest-selling
Russian title in the United States three years in a row. |
