Junk food does
more than make you fat
We all know that
junk food isn't good for you. There's a reason they call it "junk,"
right? But a new study suggests that eating food full of chemicals and high in
fat, sodium and sugar may also reduce your interest in eating healthier foods.
The new study
published in Frontiers in
Psychology involved two groups of rats that were appropriately
called Chow and Cafeteria.
Scientists fed
both groups typical rat food, but the group called Cafeteria also got
additional access to highly processed human foods. Their diet included cookies,
cakes, dim sum and meat pies.
Yum. Or so the
rats thought -- so much so that after two weeks scientists noticed the rats
that were eating the junk food lost their desire to eat anything else.
Essentially they were junk food addicts; their bodies stopped responding to the
normal impulse to seek a more balanced diet.
This was a rat study, not a human one, but it
did suggest to scientists that eating a diet rich in processed and fatty foods
may do more harm than adding pounds.
