Today I want to discuss two nutrition concepts that I
believe are under-discussed and often forgotten. I also think that these two concepts should
be at the forefront of your mind when eating for fat-loss, health, or even
performance. While I obviously believe
in a paleo/primal template, I think that these two concepts go beyond
paleo/primal and should be adhered to even if you’re not adhering to a
paleo/primal template. In short I think
these may be the two most important nutrition concepts!
So, what are these two overarching concepts you ask??? They are: Nutrient Density, and Caloric
Density. I’ll discuss each in kind and
then tie them together at the end…
The Concept of
Nutrient Density
Nutrient density is pretty much exactly what it sounds
like… How many nutrients, or how much
nutrition are you getting per unit eaten.
We’ve all heard the term (and understand the term?) “empty calories”. Well, nutrient dense foods are pretty much
the opposite of empty calories. For
illustration purposes let’s look at potato choices…

The chart above represents the nutrition information per
100g serving of each kind of potato. I’ve removed the “noise” and narrowed it down
to only applicable beneficial nutrients, ignoring other nutrition high points
like calories and macronutrients. I’ve
noted the high values in a column with a red font, and the low values with a
green font. When I look at this chart it
looks pretty obvious to me that Yam’s and Sweet Potatoes contain the most
nutrition per 100g serving, with White Potato and Russet Potato close
behind. It’s also VERY obvious to me
that instant potatoes have the least nutrition per 100g serving. As a side note the instant potatoes are also
more than 4 times higher in calories for the 100g serving! More to come on that soon…

I believe it’s pretty hard to argue with the idea that we
should put nutritious foods in our body.
Whether you buy into a paleo template, prefer a vegan diet, or believe
in some other way of eating, I think we can all get behind this idea. When
considering what to put into your body, consider which food is most nutrient
dense. You may not know off the top
of your head whether broccoli is more nutrient dense than kale, but I bet you
know whether asparagus is more nutrient dense than Kraft macaroni and
cheese. It feels like I’m stating the
obvious here, but I feel this concept is missed by many…
You’re trying to not only power your body, but feed it the
nutrition in needs to thrive. We can
easily accomplish this if we keep the concept of nutrient density in mind. Avoiding empty calories is a great start, but
always considering the nutrient density of what you’re about to consume is
taking it to the next level. Keep
nutrient density at the forefront of your mind as you make choices about what
goes in your mouth.
The Concept of Caloric
Density
This concept is also pretty straight forward but often
overlooked. Caloric density is about how
many calories a food brings you per unit consumed. Intrinsically we know that a Reeses peanut butter
cup is more calorically dense than say broccoli, but again let’s take it a step
further…
Let’s go back to the foods we looked at above:
Calories
|
|
White Potato
|
69
|
Sweet Potato
|
86
|
Yam
|
118
|
Russet
|
79
|
Instant Potato
|
365
|
Looking at the difference between the processed packaged
food and the whole foods, it’s pretty easy to imagine how eating a lot of these
calorically dense foods might be a problem.
This may seem pretty obvious when vilifying something like instant
mashed potato, but let’s look at a couple other scenarios…
Calories
|
|
2-slices Daves
Killer Bread Good Seed Light
|
150
|
2-Leaves Romaine
Lettuce
|
15
|
2-Slices Paleo
Bread (Julien Baking Co.)
|
120
|
1-serving Spinach Fettuccini
(Z Pasta Co.)
|
200
|
1-cup Spaghetti
Squash
|
42
|
The point here is that even if we’re looking at seemingly “healthy”
options like Dave’s Killer Bread, Paleo Bread, or Spinach Fettuccini, we’re
still looking at calorically dense items, and these items won’t help you be
the healthiest version of yourself.
If you’re looking to make a sandwhich, your best option will always be
lettuce instead of bread no matter what the bread is. Likewise, if you’re looking to have a pasta
dinner, your best option will always be a veggie substitute for pasta
(spaghetti squash, zucchini noodles, etc), no matter what the pasta is.
Putting it Together
Taking these two concepts on their own merit is good, but
putting them together you end up with a foundation for making nutritional
choices no matter what your eating framework (Paleo, Vegetarian, Vegan, etc.)
is. If the question is what should I
drink with dinner, your best option will almost always be the least calorically
dense (water, tea, etc); unless you have an option that if relatively
nutritionally dense for the number of calories it brings (IE- low sugar
Kombucha). Taking into account nutrient density and caloric density almost
always leads you to the least processed food, which is exactly where most of us
should be headed.
Are there exceptions to this policy? Well, yes… But not many. A couple that come to mind off the top of my
head are post-workout nutrition for athletes, and people eating a ketogenic
diet. Athletes MAY want to pursue quick
digesting carbs and protein in the post-workout window, and these foods tend to
be less nutrient dense and more calorically dense. Someone trying to maintain nutritional
ketosis will often want to choose foods that are very high in fat, which are
very calorically dense. That said, aside
from a few small exceptions this policy works for almost all people almost all
of the time…
As you go out into
the world to make nutritional choices today, consider using nutrient density
and caloric density to guide your decision making!
