History
has shown every time a "new and innovative" artificial sugar
substitute or weight loss product is created more studies prove how these
"sugars" affect brain health. Do you, like thousands of others, drink
diet sodas to control weight through calorie consumption? A 2012 study suggests
that it may be time to reconsider the
role of artificial sweeteners in your life. In a paper published in the
journal Physiology & Behavior, researchers found that diet soda — along
with other artificially sweetened foods — may sabotage weight-loss plans by
changing how the brain’s reward center responds.
This
study out of the University of California, San Diego split 24 young adults into
two groups: one group drank at least one serving of diet soda every day, while
the other avoided artificially sweetened drinks. After several weeks,
participants had their brains scanned while they switched between drinking
naturally and artificially sweetened water. This allowed researchers to track
exactly how the brain responded to sweeteners.
The
brains of the adults who had consumed diet soda regularly responded very
differently from those of non-drinkers, notably in brain areas related to
reward. And the more participants had drunk, the more pronounced this
difference.
According
to researchers “[Diet soda drinkers] who consumed a greater number of diet
sodas had reduced caudate head activation. These findings may provide some
insight into the link between diet soda consumption and obesity.”
How artificial
sweeteners confuse your BRAIN:
The
caudate head is a part of the brain involved in controlling food intake and
signaling reward — a kind of mental red light that says “enough!” Decreased
caudate head activity in diet soda drinkers suggests that this careful reward
system was thrown off.
Researchers
posit that consuming diet soda confused the caudate head’s normal reward
processing behavior: because sweet tastes didn’t always signal incoming energy,
the brain trained itself to dampen its reactions. These inaccurate caloric
predictions made diet soda drinkers more likely to consume additional calories
later in the day.
Small choices can
affect your BRAIN:
While
further research remains to be done, this findings provide insight into how
simple lifestyle choices can influence your brain. Inundate your brain with
artificial sweeteners, and it responds in one way — but give it positive,
stimulating experiences, and it could respond in another. Various other studies
have found positive changes in the brain as a result of regular exercise,
proper sleep, and many other factors.
So pick your habits wisely, for your body
and your brain!
