After studying all of the research, the reviews' authors concluded that there was "no evidence to suggest that ingestion of fructose" had an adverse effect on body weight or serum triglycerides.
Overall, the vast majority of scientific literature confirms the safety and benefits of fructose use. Fructose has a low glycemic index and, unlike table sugar or HFCS, it does not cause a rapid rise and subsequent large fall in blood glucose levels.
Research released last year by Dr. Bernadette Marriott, Senior Scientist and Principal Associate for Abt Associates, found that although dietary fructose consumption has increased in recent decades, relative consumption of fructose compared to other sugars has remained constant.
A 2008 meta-analysis by Geoffrey Livesey and Richard Taylor found that moderate fructose consumption (50 grams or less per day) had no negative effect on the body and may even be beneficial, while high doses of pure fructose (100 grams/day or less) had no effect on body weight. Marriott also found that average fructose consumption across all age groups is approximately 49 grams per day, which is well below the 100 gram threshold found by Livesey and Taylor and is at a level they report may provide benefits.
Health professionals say the recent reviews demonstrate that fructose could be a useful tool in the battle against obesity.
"Fructose is sweeter than sugar and so less can be used to sweeten foods and beverages," said
