Fructose: Sugar's Dark Side

Fructose: Sugar's Dark Side

Sugar is sweet, but one would be hard pressed to consider it a "super food." Some people actually refer to it as the "devil."

Sugar is actually made up of two simple sugars. Half is the sugar called glucose, the body's most basic fuel. The other half is another sugar known as fructose, which sounds harmless - almost as if it is derived simply from fruit. Health scientists have long held suspicions about fructose, but most evidence against the simple sugar was circumstantial. A new study has illustrated that this form of sugar is truly bad news.

Researchers at the University of California, Davis devised a complicated study pitting fructose against glucose that involved drinks sweetened with the different sugars. Volunteers drank the equivalent of 3 sodas a day. The participants drinking the fructose sweetened beverage had increased LDL "bad" cholesterol and blood fats, while the glucose drinkers had no rise in these risks for heart disease. Add to those heart disease risks the fact the fructose caused a decrease in insulin sensitivity - a sign of risk for type 2 diabetes. Interestingly enough, the fructose drinkers gained an average of 3 pounds during the 3 month study and the glucose drinkers gained no weight.

Preliminary data from new studies show that regular sugar and high-fructose corn syrup each seem to have the same effect as fructose alone -- even though both are only about half fructose and half glucose (normal corn syrup is 100% glucose).

So when folks ask me if sugar is the "devil", I might just have to tell them the answer may already be in their hearts.

things marketed as "healthy" are often times the biggest lies out there... they'll put a "smart choice" label on ANYTHING just to sell it and justify it with really stupid facts when in reality, it just isn't good for you.

After I read this article yesterday, I went home and looked in my kitchen cabinets and almost everything I have in my house has high-fructose corn syrup in it!!! Even the "healthy" Quaker oatmeal bars that I bought have it in it as the second listed ingredient. Very think that even what we are to believe is "healthy" for us...really isn't. I am going to try and take the time now and look at the ingredients before I buy anything.

Whatever. I don't believe in such studies: next week there will be one about how wonderful sugar is and how we all should have it every day. I like sugar and I'll keep on eatig it whenever I like. In moderation, everything is good.

Seems counterintuitive to a girl just out of Biochemistry class. Fructose is an essential part of the most basic (and universal) energy reaction, glycolysis. Glucose comes in, gets a phosphate group attached to it, then turned into fructose, and then that fructose gets a second phosphate group and then basically it splits into two 3 carbon sugars blah blah blah blah. Anyway, fructose can enter the pathway pretty easily, so it just seems... weird. Not that I'm saying they're WRONG obviously, the body is ridiculously complex, it makes my brain run screaming from my skull, it's just unexpected.

I haven't had soda or cola in.... too long for me to remember and quite frankly I really don't miss it. And the last time I drank coke I just drank (a sip) it out of respect since I was invited to some meeting. Yeah, im lucky im not quite the sugar addict but Im a sucker for salty food. heh. you win some you lose some.

yes! this is SO true. i was forced to go on an extremely low (basically no) sugar diet because of a candida albicans infection in my intestines and i have really learned about how sugar is poison in the body. almost EVERY physical (and emotional!) ailment can be linked to sugar consumption. it really just takes a horrible toll on the body in so many ways and i feel SO great not having it. i'm energized, happy, and invigorated all the time. i really recommend the book "get the sugar out" by Ann Louise Gittleman. it sheds light on a lot of the horrors we're too afraid to face, because let's face it... we're all sugar addicts. and that's really what it is: an addiction.

I won't give up bread, sugar or soda, in moderation. They make me too happy. Long live carbs, candy and cola!
