Fructose Effects

Fructose, or fruit sugar, is a simple monosaccharide found in many plants. It is one of the three dietary monosaccharides, along with glucose and galactose, that are absorbed directly into the bloodstream during digestion. Fructose is generally regarded as being 1.73 times as sweet as sucrose. Fructose is a common sweetener used in many products such as soda as a result.  There is now some new research evidence of cardiovascular disease and diabetes risk is present in the blood of adolescents who consume a lot of fructose, a scenario that worsens in the face of excess belly fat. An analysis of 559 adolescents age 14-18 correlated high-fructose diets with higher blood pressure, fasting glucose, insulin resistance and inflammatory factors that contribute to heart and vascular disease. Heavy consumers of the mega-sweetener also tend to have lower levels of cardiovascular protectors such as such as HDL cholesterol and adiponectin, according to researchers at the Medical College of Georgia at Georgia Health Sciences University. These dangerous trends are exacerbated by fat around their midsection, called visceral adiposity, another known risk factor for cardiovascular disease and diabetes. The association did not hold up for adolescents with more generalized, subcutaneous fat. \"It is so very important to provide a healthy balance of high-quality food to our children and to really pay close attention to the fructose and sucrose they are consuming at their home or anyone else’s,\" said Dr. Vanessa Bundy, an MCG pediatric resident. Drs. Bundy and Norman Pollock, bone biologist at MCG’s Georgia Prevention Institute are co-first authors on the study published in The Journal of Nutrition. \"The nutrition that caregivers provide their children will either contribute to their overall health and development or potentially contribute to cardiovascular disease at an early age,\" Bundy said. The best way caregivers can support healthy nutrition is to be good role models, she said. A healthy diet with plenty of physical activity — not dieting — is the best prescription for growing children. While animal studies have had similar findings, evidence in children is needed to support dramatic steps to curb consumption, such as asking schools to remove soda and other vending machines or, at least, to limit access, Pollock said. The researchers noted that more study is needed to flesh out the relationship between high fructose consumption and cardiovascular risk and whether these early associations forebode adult disease. Fructose, or fruit sugar, is found in fruits and veggies but also in high fructose corn syrup, the sweetener used liberally in processed foods and beverages. Researchers suspect growing bodies crave the cheap, strong sweetener and companies often target young consumers in ads. Cane and beet sugars have been used as the major sweetener in food manufacturing for centuries. However, with the development of Fructose as a product, a significant shift occurred in the type of sweetener consumption.  This change happened in the 1970s.  However, with the increase of consumption, the total fructose intake has not dramatically changed.   \"Fructose itself is metabolized differently than other sugars and has some byproducts that are believed to be bad for us,\" Bundy said. \"The overall amount of fructose that is in high fructose corn syrup is not much different than the amount in table sugar but it’s believed there’s something in the syrup processing that plays a role in the bad byproducts of metabolism.\"
