Okay, so I'm going into the HowStuffWorks
kitchen area.
Let's see Cherry Coke.
42 grams of sugar in a Cherry Coke.
How about Mountain Dew?
46 grams in a can of Mountain Dew. OK.
I’m one of those weird people who likes
to look at the nutrition facts label on food,
and something that’s always bothered me
is how there isn’t a percent daily value
listed for sugar.
39 grams of sugar in a can of Coke seems like
a lot, but is it?
On May 20th, 2016, the Food and Drug Administration
introduced an updated nutrition facts label
which they said reflected “new scientific
information.”
Among the changes were updated serving sizes,
calories are way bigger, and this: an entirely
new line for ‘added sugars’ that also
includes a percent daily value.
But let’s back up.
Why does it matter how much sugar a person
consumes?
Sugar, whether it’s natural or added, is
a type of carbohydrate
that our bodies use for energy.
Fruits, vegetables, and dairy foods can naturally
contain sugar.
But the FDA defines ‘added sugars’ as
those that are either: Added during the processing
of foods; Sugars from syrups and honey; And
sugars from concentrated fruit or vegetable
juices that are in excess of what would be
expected from the same volume of 100 percent
fruit or vegetable juice of the same type
A food science expert explains why added sugars
can be harmful.
"Oh, they're not needed.
And they dilute the nutritional quality of
whatever they're added to.
They give you calories, but they don't give
you any additional nutrients."
The FDA recommends limiting added sugar intake
to no more than 10% of a person’s total
daily calories.
For adults, this equals about 50 grams, or
12.5 teaspoons, of sugar per day.
In other words, a little more than a can of
Mountain Dew.
The World Health Organization recommends even
less.
Just 5% of a person's daily calories, which
equals about 25 grams, or 6 teaspoons, per day.
Or one package of peanut M&Ms.
For reference, the average American adult
consumes 75 grams of added sugar per day,
or about 19 teaspoons.
So where does all this added sugar come from?
If your first answer is soda, you might be
surprised to know that American soda consumption
has steadily decreased in the past 15 or so
years.
The truth is that sugar can be found in just
about everything we eat and drink, but it’s
often disguised under other names, like glucose,
fructose, maltose, dextrose (basically anything
that ends with -ose), cane juice, cane syrup,
high-fructose corn syrup, cane sugar, corn
sweetener, molasses, malt syrup, invert sugar,
or fruit juice concentrates.
Manufacturers list them in this way to break
up the amount and make it appear like there’s
less overall sugar in a product.
And that’s one of the reasons the FDA is
updating the nutrition label – so consumers
are aware of how much added sugar is in their
food.
“You will no longer need a microscope, a
calculator, or a degree in nutrition to figure
out whether the food you’re buying is actually
good for our kids.”
"If you're going to be eating healthfully,
you want to keep the amount of sugar down.
Not just for reasons of nutrients, but also because
there's so much evidence that people who eat
a lot of sugar have a higher risk for obesity,
Type 2 diabetes, heart disease, and so forth."
If that's the case, why hasn't the public
been better informed? To answer that, we need
to go back in time.
"In the 1960s, a lot of attention in the scientific
community was directed to trying to understand
the dietary factors in the American diet,
and how they might be linked to coronary heart disease.
American men were dying of coronary heart
disease at higher rates than other countries.
And so, we thought our specific American diet
might have something to do with that."
That’s Cristin Kearns, who along with co-authors
Laura Schmidt and Stan Glantz, recently published
a paper in JAMA Internal Medicine revealing
that the sugar industry sponsored research
that purposefully singled out fat as the dietary
cause of heart disease, while downplaying
the evidence that sugar consumption was also
a factor.
"As more evidence began to link sucrose consumption
to coronary heart disease, the sugar industry
got involved with the research themselves
in an attempt to discredit some of the evidence.
And, I believe, direct attention away from
that research onto the research linking fat
to coronary heart disease."
Founded in 1943 by members of the U.S. sugar
industry, the Sugar Research Foundation was
dedicated to communicating and supporting
sugar’s dietary role to the public.
It later evolved into what is currently called
The Sugar Association.
"The documents that we have - the industry
is certainly talking about how to protect market share.
So, the Sugar Research Foundation was created
to protect sales."
Now, industry sponsored research is nothing
new, but the effects of the Sugar Research
Foundation's manipulation were far-reaching.
When the U.S. government first published their
Dietary Guidelines for Americans in 1980,
they recommended avoiding too much fat, saturated
fat, and cholesterol, which they linked to
a greater chance of having a heart attack.
They did recommend limiting sugar intake,
but only because it could cause tooth decay.
Even today, walk into any grocery store and
look at the so-called 'healthy products.'
They usually advertise themselves as low-fat
or low-cholesterol, but say almost nothing
about the sugar content.
After the JAMA article came out, the Sugar
Association released a statement: "We acknowledge
that the Sugar Research Foundation should
have exercised greater transparency in all
of its research activities, however, when
the studies in question were published funding
disclosures and transparency standards were
not the norm they are today.”
"I think it was interesting that they acknowledged
that they should have been more transparent.
I actually didn't expect them to say that.
However, that doesn't exonerate the industry
from their actions."
Despite the manipulation by the Sugar Research
Foundation, whether added sugar contributes
to coronary heart disease is still hotly debated.
"What you have is an enormous amount of evidence
from correlation and association that people
who eat diets that are high in sugar tend
to have a greater risk for obesity, Type 2
diabetes, and heart disease."
The best thing you can do?
Look at the labels.
Know what's in your food, and how much.
And if you're worried about added sugar, a
simple solution is just to avoid prepackaged foods.
Buy fresh ingredients and cook them yourself.
That way, you can know exactly what's going
into the food you eat.
So if you’re wondering why you haven’t
seen the new nutrition facts label yet, it’s
because manufacturers have until July of 2018
to comply with the changes.
And if a manufacturer makes less than $10
million a year in annual food sales, they’ll
have another year to make the change.
Thanks for watching, guys.
