| For several million years, humans existed on a diet of animals and vegetation.
It was only with the advent of agriculture a mere 10,000 years ago - a fraction
of a second in evolutionary time - that humans began ingesting large amounts of
sugar and starch in the form of grains (and potatoes) into their diets. Indeed,
99.99% of our genes were formed before the advent of agriculture; in biological
terms, our bodies are still those of hunter-gatherers.
While the human shift to agriculture produced indisputable gains for man -
modern civilization is based on this epoch - societies where the transition from
a primarily meat/vegetation diet to one high in cereals show a reduced lifespan
and stature, increases in infant mortality and infectious disease, and higher
nutritional deficiencies.
Contemporary humans have not suddenly evolved mechanisms to incorporate the high
carbohydrates from starch- and sugar-rich foods into their diet. In short, we
are consuming far too much bread, cereal, pasta, corn (a grain, not a
vegetable), rice, potatoes and Little Debbie snack cakes, with very grave
consequences to our health. Making matters worse, most of these carbohydrates we
consume come in the form of processed food.
That 65% of Americans are overweight, and 27% clinically obese, in a nation
addicted to sesame seed buns for that hamburger, with a side of French fries and
a Coke, is no coincidence. It is not the fat in the foods we eat but, far more,
the excess carbohydrates from our starch- and sugar-loaded diet that is making
people fat and unhealthy, and leading to epidemic levels of a host of diseases
such as diabetes.
If you are experiencing any of the following symptoms, chances are very good
that the excess carbohydrates in your body are, in part or whole, to blame:
* Excess weight
* Fatigue and frequent sleepiness
* Depression
* Brain fogginess
* Bloating
* Low blood sugar
* High blood pressure
* High triglycerides
We all need a certain amount of carbohydrates, of course, but, through our
addiction to grains, potatoes, sweets and other starchy and sugary foods, we are
consuming far too many. The body's storage capacity for carbohydrates is quite
limited, though, so here's what happens to all the excess: they are converted,
via insulin, into fat and stored in the adipose, or fatty, tissue.
Any meal or snack high in carbohydrates generates a rapid rise in blood glucose.
To adjust for this rise, the pancreas secretes the hormone insulin into the
bloodstream, which lowers the glucose. Insulin is, though, essentially a storage
hormone, evolved over those millions of years of humans prior to the
agricultural age, to store the excess calories from carbohydrates in the form of
fat in case of famine.
Insulin, stimulated by the excess carbohydrates in our overabundant consumption
of grains, starches and sweets, is responsible for all those bulging stomachs
and fat rolls in thighs and chins.
Even worse, high insulin levels suppress two other important hormones -
glucagons and growth hormones - that are responsible for burning fat and sugar
and promoting muscle development, respectively. So insulin from excess
carbohydrates promotes fat, and then wards off the body's ability to lose that
fat.
Excess weight and obesity lead to heart disease and a wide variety of other
diseases. But the ill effect of grains and sugars does not end there. They
suppress the immune system, contributing to allergies, and they are responsible
for a host of digestive disorders. They contribute to depression, and their
excess consumption is, in fact, associated with many of the chronic diseases in
our nation, such as cancer and diabetes.
