Diet Danger: High Fructose Corn SyrupThe Effects of Corn Syrup Aren't So Sweet-- By Becky Hand, Licensed & Registered Dietitian http://www.sparkpeople.com/resource/nutrition_articles.asp?id=486SparkPeople Sponsors help keep the site free! Trying to save money, food companies introduced High Fructose Corn Syrup (HFCS) into the food market in the 1970s. Sweetening manufactured foods this way is profitable, because it is less expensive and much sweeter than sugar, yet easy to transport because of its liquid state. Today HFCS is found in a variety of foods from soda pop to ketchup, fruit drinks to salad dressings, cereals, breads, flavored yogurt, and sauces. What is Fructose? Fructose, a monosaccharide, is sometimes called “fruit sugar” because it is naturally found in fruits. Fructose is also found in honey, and is a component of table sugar (sucrose), which is a disaccharide composed of fructose and glucose. When we eat most carbohydrate foods, the blood sugar level increases and insulin is secreted to transport the sugar into the body’s cells. Besides helping to transport blood sugar, insulin also triggers the release of a hormone called leptin. Leptin helps control hunger by signaling the brain that the body is full and therefore to stop eating. The interesting fact about fructose is that it is metabolized in a totally different way than other carbohydrates. It does not stimulate or require insulin for transportation to the cells. Since there is no need for insulin release, there is also no secretion of leptin. Therefore the feeling of satiety is altered—you continue to eat and possible overeat. (continued...)
