High Fructose Corn Syrup: Not so sweet
Have you seen those obnoxious commercials about high fructose corn syrup (HFCS), how it is "all natural" and mocking those who try to say anything bad about it? Well, an overly processed sweetener is not what I consider "all natural." Yesterday at clinic, we were discussing sweetener options, including the new stevia derivative, Truvia. We concluded the closer to nature, the better the sweetener, which pretty much left us with stevia (sweetener made from the whole plant, not just one sweet element of it), honey, and maple syrup.
What is so bad about high fructose corn syrup? There are studies showing that consuming HFCS can turn down leptin, a hormone that acts as one of the body's regulators of satiety (or feeling full). See the above picture? The mouse on the right lacks the gene that makes the hormone leptin. The American Journal of Clinical Nutrition has implicated HFCS in the obesity epidemic. Now there are claims that the process of manufacturing HFCS contaminates the product with mercury. Gee whiz, I see nothing wrong with any of that!
The Corn Refiners Association has a rebuttal for every claim against HFCS, but the consumers have the final say. Refuse to buy products with high fructose corn syrup.
Here is a spoof of the HFCS commercials by the guys who made the movie King Corn. And just to make your grocery store trip a bit more challenging, Treehugger.com takes a look at the new stevia-derived sweeteners.
