Hey, don't tamper with the evidence.
What do we got so far, Sally?
Well, I think we're up against the toughest case
this lab has ever had.
I've got a serving of vanilla ice cream.
That's exhibit A in the new caloriemograph our lab just got.
Oh, yes.
We're the first to get the multimillion dollar
caloriemograph.
Checking calories, huh?
You know, calories provide a measure of how much energy
is in a serving of this food. That's right.
And calories are assessed based on serving size.
And as a calorie scene investigator,
I have come to find that appearances can be deceiving.
Consuming too many calories per day can lead to obesity
and being overweight.
Here's what doesn't add up, Derrick.
I'm getting a calorie reading of 150 calories for 1 serving
of exhibit A, vanilla ice cream, while an identical serving
of fruit juice pop is only 60 calories.
The same serving size of the frozen juice pop has almost
a third of the calories of exhibit A?
That's right.
Then let's call the juice pop exhibit B.
Good idea.
Let's check past histories to see if there's a trend.
Hand over those chips.
I want to get an analysis of them.
This isn't gonna be pretty.
[music]
Oh, only 170 calories per serving.
Not so bad.
But Derrick, do you know the reading I'm getting
for a serving size?
Nine to fifteen chips.
Yeah? No biggie.
Actually, it's really not very big.
The point is you've already had about 30 without even thinking.
How can this be? I didn't even eat the whole bag.
I've got to contact Lieutenant Vain
and tell him our new finding.
[music]
Thank you, Derrick.
Let me know when the final results are in.
Well, Pete, while we were making a case for calories,
Derrick seems to think that the answer lies in serving size.
And serving sizes are not always what they appear to be.
What's going on here?
Ma'am, this is a calorie scene investigation.
I'm CSI Lieutenant Vain.
I'm going to have to inspect your groceries
before you enter the scene.
What are you looking for?
We're looking for calorie content and its elusive
accomplice, serving size.
These will have to go back to the lab.
The lab? Why the lab?
Don't worry, ma'am.
With our multimillion dollar caloriemograph,
we can tell exactly how many calories
are in a single serving.
Multimillions?
Lieutenant Vain, there is no need to go to all that trouble.
Why don't you enlighten me?
When I go shopping,
I just look at the nutrition facts label.
Just the nutrition facts label, ma'am?
It tells me everything I need to know about the percent
daily values of the food that I buy for my family.
Let me show you.
Each label actually starts out with serving size
and calories per serving size.
So peanut butter, serving size is 2 tablespoons,
that's 190 calories.
Hummus is 70 calories for 2 tablespoons.
Hummus, the Middle Eastern dip made from mashed cooked
chick peas, blended with lemon juice, tahini, garlic,
olive oil, and salt.
It became quite popular in the U.S., but what I didn't know is
that it was so low calorie.
But here's the tricky part.
While 2 tablespoons of peanut butter or hummus might be
satisfying, they aren't necessarily what I would eat
in a sitting.
And they certainly aren't what my growing son would eat.
He's on the swim team and his idea of a serving can be totally
different from what's on a label.
Luckily he swims a lot.
Ma'am, what about this bag?
May I?
Mm, while this bag might seem like one serving
to my son's untrained eye, there are actually
two and a half servings here.
That means instead of 140 calories,
it's actually 350 calories.
And that extra 200 calories a day can add up to 20 pounds
of weight gain over the course of a year.
What's interesting is that serving sizes are often given
in familiar measurements like cups or pieces.
Even so, a package may contain more than one serving.
For instance, milk is calculated based on an 8-ounce cup serving.
I guess that is just the way the calorie cookie crumbles.
