Sugar: Hiding in plain sight - Robert Lustig
Sugar is playing hide and seek with you.
You'd think it would be pretty easy for you to win,
considering all the sugar in
sodas, ice cream, candy, and big white bags labeled sugar.
People get about half of their added sugars
from those drinks and treats,
so it might seem like sugar
is hiding in plain sight,
but like someone in the witness protection program,
the other half is hidden in places you'd least suspect.
Check the ingredients on ketchup, bologna,
spaghetti sauce, soy milk, sports drinks,
fish sticks, and peanut butter.
You'll find sugar hiding in most of those products.
In fact, you'll find added sugars
in three-quarters of the more than 600,000 items
available in grocery stores.
But how is sugar hiding?
Can't you just look on food labels?
It's not that easy.
Just like your friend Robert
might go by Bob, Robby, Rob, Bobby, or Roberto,
added sugar has a lot of aliases.
And by a lot, we don't mean five or six,
try fifty-six.
There's brown rice syrup, barley malt,
demerara, Florida Crystals, muscovado,
and, of course, high fructose corn syrup,
sometimes called HFCS, or corn sugar.
Even sugar's tricky nicknames have nicknames.
Grape or apple concentrate has the same effects on your body
as its 55 sugary twins.
And even though organic evaporated cane juice sounds healthy,
when you evaporate it,
you get sugar!
Chemically speaking, it's all the same.
And even trickier,
when multiple added types of sugars
are used in one type of product,
they get buried down in a long list of ingredients,
so the sugar content might appear to be okay,
but when you add them all together,
sugar can be the single biggest ingredient.
Currently, the FDA doesn't suggest
a recommended daily limit for sugar,
so it's hard to tell if this 65 grams in a bottle of soda
is a little or a lot.
But the World Health Organization recommends
limiting sugar to just 5% of your total calories,
or about 25 grams per day.
So, 65 grams is well over twice that amount.
But just what is sugar?
What's the difference between glucose and fructose?
Well, both are carbohydrates
with the same chemical composition
of carbon, hydrogen, and oxygen.
But they have very different structures
and behave quite differently in our bodies.
Glucose is the best source of energy
for nearly all organisms on Earth.
It can be metabolized by all organs in the body.
Fructose, on the other hand,
is metabolized primarily in the liver,
and when your liver gets overloaded
with sweet, sweet fructose,
the excess is metabolized to fat.
Fresh fruits actually contain fructose,
but it's naturally occurring
and doesn't cause an overload
because the fiber in fruit slows its absorption.
This gives your liver the time it needs
to do its job.
It's sugar that makes cookies chewy
and candy crunchy.
It even turns bread crust a beautiful, golden brown.
It's also a great preservative;
it doesn't spoil or evaporate,
so the foods it's added to are easier
to store and ship long distances
and tend to be cheaper.
That's why sugar is hiding everywhere.
Actually, it might be easier to list the foods
that added sugar isn't hiding in,
things like: vegetables, eggs, meats,
fish, fruit, raw nuts, even your kitchen sink.
Simply choosing water over soda, juices, and sports drinks
is a great way to avoid hidden added sugar.
At the very least,
try to pay attention to food labels,
so you can keep your sugar intake at a healthy level.
Because in this game of hide and seek,
every time you don't find added sugar,
you win!
