A new comprehensive review, recently published in Critical Reviews in Food Science and Nutrition, concludes that fructose does not increase food intake or impact body weight or blood triglycerides in overweight or obese individuals.
The review examined data regarding the normal consumption of fructose and any subsequent development of alterations in lipid or and/or glucose metabolism or weight gain in overweight people. Researchers were unable to find any relationship between fructose and hyperlipidemia or increased weight. These findings support the results of a similar review that analyzed the role of fructose on blood lipids, glucose, insulin and obesity among the healthy, normal weight population.
Dr. Laurie Dolan, lead author of both studies concluded that "there is no evidence that ingestion of normal amounts of fructose is associated with an increase in food intake or body weight (compared to other carbohydrates), when it is not consumed in caloric excess. This is true for both normal weight people and people that are overweight or obese."
Fructose is a natural simple sugar found in fruits, vegetables and their juices, as well as honey. In its pure form, fructose has been used as a sweetener since the mid-1850s and has advantages for certain groups, including people with diabetes and those trying to control their weight. Fructose in crystalline form has been widely used for the past 20 years as a nutritive sweetener in foods and beverages.
Although many consumers have confused crystalline fructose with high fructose syrups [also known as high fructose corn syrup (HFCS) and isoglucose], they are not the same. Like sucrose, high fructose syrups contain nearly equal amounts of glucose and fructose. This change in composition is chemically significant and leads to differences in food applications and specific physiological responses.
Both of the recent fructose reviews utilized an evidence-based app
