Having
a hard time kicking the sweets habit? It goes a little deeper than they just taste good. In 2007, French scientists researched sugar in relation to
addictive behavior. Rats were given the option of drinking plain water,
water laced with sugar, and water laced with cocaine. After 24 hours, 94%
of the rats preferred the sugar water over cocaine, one of the most
addictive drugs. This leads researchers to believe that sugar feeds the
body’s reward system, similarly to addictive substances, causing
addictive tendencies.
Let’s back
track and look at the science behind this. Neurotransmitters in the
brain relay information causing a “feeling response” such as happiness,
tiredness, sadness, or relaxation. The strength or weakness of the
neurotransmitter plays an important role in a person’s ability to
control food portions and choices. Dopamine is the body’s “feel good”
chemical and is found in high quantities when addictive substances such as
drugs, alcohol, and nicotine are consumed. As
high quantities of dopamine are released they overstimulate the
neuroreceptors causing a "high". Continuous overstimulation slows the
body’s natural release of dopamine, creating a dependence and compulsive
behavior with the substance, in this case sugar, to experience the same
amount of pleasure. As with drugs, the body becomes tolerant to the
same level of stimulus, so more is required to achieve the same
response…meaning you eat more!!
So
the next time you look at a brownie or cupcake, look at it as more than
something that tastes good and more than something that will end up on
your midsection, but as a drug to which you can easily become dependent.
Snack on...but snack wisely!!!
