Diets -
Nutrition, Evolution, and Having
a Healthy Diet
Nutrition has everything to do with health. This isn’t news,
exactly, but looking around at the crazy information on the market, one
wonders if anyone actually makes the connection: what you eat affects
how you feel. It’s that simple. Your health depends on the food
choices you make in both the short and long term.
Take a pill, and all you’ve done is treat a symptom. Change your
eating habits, and create a lasting change in your well-being. There
are so many approaches to eating, however, and so much conflicting
information that it’s come down to this simple question: does whatever
you’re eating right now make sense?
Well, sense isn’t common, and it does depend on some good
information. So here is something to consider: what kind of foods are
humans evolved to eat? Cheetos? Don’t think so. That’s a no-brainer,
but what about some others that we counted as healthy staples until
recently, like bread and pasta. Go way back in your imagination, to
hunter gatherer days – before agriculture and the obesity which followed
for the first time among humans – and consider what would be part of our
ancestors’ normal diet. If you’re about to pop something into your
mouth that wasn’t around before agriculture, (a relatively recent
development in human history), then eat it knowing it’s not considered a
‘normal’ food by your body. Foods your body considers ‘normal’
contribute to your health, other foods are either neutral or harmful.
How simple is that?
A well-known exploration of this concept that certain foods help our
bodies thrive is Dr. Peter D’Adamo’s book, “Eat Right 4 Your Type,” in
which he bases his lists of what to eat and avoid on blood type.
D’Adamo asserts that type O is the oldest type, and the newer A type
didn’t show up on the scene until agriculture. So, Os should eat lots
of meat and veg because that blood type doesn’t know how to handle too
much grain. Type As can eat grain, but not dairy. Dairy is a category
reserved as a ‘normal’ food only for the yet more recent human blood
type, AB. (Maybe we’ll evolve a new type that can handle Cheetos and
red licorice, my personal favorite abnormal foods).
D’Adamo supports his blood-type theory with all kinds of careful
research, and so what? Does it make sense that humans should rely
primarily on foods that occur naturally? Absolutely. If you’re going
to eat a grain like wheat then, eat it whole, or don’t eat it at all,
and don’t eat much of it anyway because humans pretty much made wheat
up! I’m not going to take the, “Does it occur naturally?” debate too
far, because it’s time to look at another researcher’s take on the food
and evolution connection.
Dr. Phillip Lipetz wrote “The Good Calorie Diet,” a book for the
weight loss market, but he also has supported his theories with all
kinds of careful research. His describes how the human response to
starvation that was developed during the ice age carries on today.
Ironic, isn’t it, that the food available to us today - rich and sweet
and abundant - causes our bodies to behave as though starvation is at
hand.
The short story for how this works is that up until the ice age,
humans ate whatever was readily available, like roots, plants, fruit,
and a little tasty carrion now and then. Along came the ice ages, and
those foods became scarce. Now humans were forced to hunt, but it was
dicey and the weapons were primitive, so spans of time occured between
kills. The result: our ancestors evolved ways to make the most of the
conversion of excess blood sugar into stored nutrition in the form of
body fat. When they starved, they lived off stored fat.
Today’s diet mimics the ice age diet: high fat and high protein, and
our genetic programming says, “Uh oh, we’re facing starvation again.
Better store up some fat.” Lipetz goes into convincing detail about
food combinations in his book. He describes some that cause the
creation of excess fat, such as butter on bread. More useful are his
combinations that actually inhibit fat formation, like lean meat with
most vegetables. In a society where obesity and its attendant health
issues are rampant, these food combinations are helpful places to focus
our attention. Yet the single most useful bit to remember from his
research is that foods which cause our bodies to create excess fat all
have one thing in common: they weren’t part of our ancestors’ normal
diet.
Armed with this overview, next time you’re about to pop something in
your mouth - whether your focus is health or weight – you don’t need to
have a bunch of rules and whacky information in mind. Just use common
sense. Ask whether it’s a food that was around before the advent of
agriculture. If it was, go for it. If it wasn’t, then consider that
your body won’t consider the food ‘normal,’ and in both the long and
short run, that’s got health consequences.
