[music] 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. [music]
