The Bad Guy: High Fructose Corn Syrup


Consumption of high fructose corn syrup (aka corn syrup), inhibits the secretion of hunger quenching hormones, such as insulin and leptin. Low levels of insulin and leptin, in turn, results in an over intake of HFCS foods.

The fructose found in sugary snacks is only recognized by the liver and does not signal to the pancreas to secrete insulin (a hunger quench hormone). Consequently, fructose is not transported to the brain to signal that your stomach is full. In essence, as you are eating HFCS containing foods you never receive a signal to stop eating. And this encourages over eating.  HFCS is only recognized in the liver, which turns it into FAT.

Consumption of HFCS can lead to fatty liver disease, high levels of triglycerides in the blood, increased insulin resistance, inflammation, and obesity.

It is found in soft drinks, baked goods, bread, cereals, canned fruits, jams and jellies, dairy desserts and flavored yogurts, and even pretzels. Yes, fructose is found in fruit. However, this “good” fructose, found in fruit is in the L-fructose form; whereas, the harmful D-fructose is found in HFCS.
