High-fructose corn syrup is a sweetener produced by processing cornstarch to yield glucose, and then processing the glucose to produce a high percentage of fructose. It is primarily used as a preservative and sweetener in a multitude of food products. You should avoid it because of the following:

1. High-fructose corn syrup has been linked directly to obesity, diabetes and metabolic dysfunction.
2. High-fructose corn syrup elevates triglycerides levels, which can lead to heart disease.
3. High-fructose corn syrup is simply empty calories with no nutritional value whatsoever.

HFCS is a group of corn syrups that has undergone enzymatic processing to convert its glucose into fructose and has then been mixed with pure corn syrup (100% glucose) to produce a desired sweetness. In the United States, HFCS is typically used as a sugar substitute and is in processed foods and beverages, including soft drinks, yogurt, industrial bread, cookies, salad dressing, and tomato soup. 

Consuming high-fructose corn syrup in moderation is becoming near impossible, seeing as nearly everything from sliced bread to salad dressing now contains the ingredient.
