ADAM:
OK Rosie, shall we try to get some ideas together for our presentation on diet and obesity?
ROSIE: Sure.
ADAM:
I can talk about the experiment I did to see if people can tell
the difference between real
sugar and artificial sweeteners.
ROSIE:
Where you have people drinks with either sugar or artificial sweeteners and they had to say
which they thought it was?
ADAM:
Yeah. It took me ages to decide exactly how I’d organise it,
especially how I could make
sure that
people didn’t know which drink I was giving them

Q22
. It was
hard to
keep track of it all, especially as
I had so many people doing it
Q21
/
Q22
– I had to make
sure I kept a proper record of what each person had had.
ROSIE:
So could most people tell the difference?
ADAM:
Yeah – I hadn’t thought they would be able to, but most people could.
ROSIE:
Then there’s that experiment I did measuring
the fat content of nuts, to see if the nutritional
information given on the packet was accurate.
ADAM:
The one where you ground up the nuts and mixed them with a chemical to absorb the fat?
ROSIE:
Yes. My results were a bit problematic – the fat content for that type of nut seemed much
lower than it said on the package. But I reckon the package information was right. I think
I should probably have ground up the nuts more than I did. It’s possible that the
scales for weighing the fat weren’t accurate enough
