Science Journal 9: The Bitter Side of Sweet


The Bitter Side of Sweet

A study done by Princeton University researchers has found that different types of sweeteners have different effects on your body.  The researches decided to test out their theory that not all sweetners have the same effects using rats.  One group of rats was fed high levels of sugar, while the other group was fed high levels of high-fructose corn syrup, a sweetener found in many soft drinks, candies, and processed foods.  The rats eating the sugar were receiving a dose that had a similar concentration to that of a soft drink.  The rats eating high-fructose corn syrup were drinking it at a much lower concentration that what is normally found in most soft drinks. The rats that were ingesting a high level of sugar had some signs of fat accumulation, but there were no severe signals that their weight was getting out of control.  The rats that ate corn syrup, on the other hand, were almost all obese, and showed major signs of fat accumulation.  Their fat followed known patterns of obesity, such as gathering around the stomach and the thighs.

During the experiment researches found out that the rats being fed the  high-fructose diet were 48% more overweight than the ones eating normal rat food.  The scientists believe that one of the main reasons for these results is that normal sugar, sucrose, must be processed by your body more than the corn syrup, while corn syrup was processed, and is made for easy consumption and absorption.  I think that these findings are very relevant to problems we are facing in society today.  An overwhelming amount of the population is overweight or obese.  During the 1970’s, the American obesity rate was 15%.  When corn syrup was introduced to the market, the number of obese citizens living in America greatly elevated, and now obese people make up around one third of America’s adult population.   

Not only does being obese make it harder to perform basic tasks during the day, but it also makes you prone to many serious diseases, such as diabetes, coronary artery disease, and cancer.  In fact, many of the rats who were consuming the corn syrup exhibited signs of the aforementioned diseases.  This study aids us in our battle against obesity, since it shows us one of the possible causes for such an increased obesity rate.  People can use this study to influence their decisions on what to eat.  They will be able to make more informed decisions, and won’t be unknowingly contributing to the obesity crisis. 

Though obesity might seem like a fair consequence for a bad choice, many adults base their (and, commonly, their children's) eating decisions based on the marketing around them.  A lot of products claim to be sugar free or low in fat, when they might actually harm you.  Another reason I think that citizens shouldn’t be held fully responsible for the rising obesity rate is because when corn syrup was first made, researchers didn’t determine whether or not there were any long term effects of it.  They might have tested it thoroughly for diseases that were common a few decades back, but something like the obesity epidemic probably hadn’t crossed their minds (or, if it did, then they just thought it would have a simple solution, such as exercise, or were very motivated by profits).  This situation can be seen now as well, since we are developing a lot of new technology, and are more commonly eating food that has been genetically modified.  We do not yet know what the long term effects of GM food are.  Even though we have tested a lot of this food, there is something that we’re still not seeing, which might come back to hurt us.   

Reading this article has made me think about what I eat, and just how little I think about my nutrition.  As a teenager, I find my attention taken by things that I consider interesting, which are not necessarily always important.  Usually, I eat things if they taste good, and pay little mind to what is in the food.  With this new information about corn syrup, I can easily cut out a large part of my diet that is unhealthy.  I can also use this information to make more conscious choices about what I eat.  While reading this article, it was important to ensure its credibility.  The author of this article is Hilary Parker, a writer for the Princeton website.  Because the main research team is affiliated with Princeton University, the article was published on the Princeton Website.  This website has a “.edu” ending, which adds credibility to it.
