So you’re sit ing in a booth at a fast-
food chicken joint. Maybe you’re there
because of a funny commercial you saw
on TV, or a nostalgia-induced craving, or
it’s convenient and you’re starving.
You unwrap the crinkly paper to
unveil a squishy bun hugging a warm
breast of fried chicken. Sizzling from
the kitchen punctures the Top 40 music
playing above. The aroma of crisped fat
intensifi es. You take a bite.
Hmmm. It tastes, well, kind of sucky.
It’s not nearly as juicy as the ad made
it look or as delicious as the ones you
remember. Yet you eat, and maybe
eat more of it than you should, as if
compelled by outside forces.
The truth is, those forces – from the
texture of the wrapping to the lightness
of the bun to the too-loud pop music
- are intentional.
Scientists have long known that
much of what you “taste” when you’re
eating isn’t about your palate. A new
branch of research is proving the
assumption that all of your senses are
at play when you eat.
To experience these fi ndings
fi rst-hand, I paid a visit to Charles
Spence, director of the University
of Oxford’s Crossmodal Research
Laboratory in London. Prof Spence,
an apple-faced man with a penchant
for brightly coloured pants, has
popularised the term “gastrophysics”
to refer to the science behind brain-
belly communication.
Prof Spence guided me through a
multi-course meal designed by Kitchen
Theory, which is kind of a pop-up
restaurant-slash-food lab that
incorporates his fi ndings. Each course,
prepared by Chef Jozef Youssef, was
meant to manipulate one of my senses.
Here’s what I learned.
HOW SIGHT MAKES YOU FAT
My fi rst course was entirely white. Four
appetisers sat atop an ivory plat er:
a snowy ball, cloud-like cot on candy,
colourless globules with the consistency
of egg yolk, and a triangular chip with a
cuboid topping. With Prof Spence looking
on, I was told to eat them in
order from sour to salty to
bit er to sweet.
I went for a chip. He asked
why. I told him the topping
looked like it was pickled, so it
might be sour. He suggested
that there could be something
else going on. Sweetness is
typically associated with round
shapes (think chocolate chip
cookies and peanut but er
cups). Hard, angled edges
(pickle spears, lemon wedges)
communicate sourness and
bit erness.
But then I bit into the chip. It
was sour, yes, but even after he
told me the topping contained
hearts of palm, white onion,
lime and olive oil, I couldn’t
taste any of those.
He explained that there’s
truth to the adage “we eat
with our eyes.” When our
food loses colour, our brain
loses context.
1/ Shut O the Neon
Prof Spence’s research
suggests that people are
so compelled by colour that
they trick themselves into
tasting what they see. In an
experiment he reviewed,
for example, many tasters
deemed a cherry-fl avoured
soft drink citrusy because it
had a vibrant orange colour. So
by avoiding processed foods in
any hue not found in nature,
you can cut down on junk like
sugary cereals, Skit les and
boxed macaroni and cheese.
2/ Look Past the Package
People tend to believe that a
product in mat e packaging is
healthier than one in a glossy
container, according to Prof
Spence. The nutrition facts are
what mat er: Always check
them when you’re shopping
for food.
3/ Swop Your Dishes
Try eating out of a small bowl
instead of a big plate. The rim
