The findings, published in the February edition of Current Opinion in Lipidology, show that when portion sizes and calories are the same, fructose does not cause any more harm than glucose.
"Despite concerns about fructose's link to obesity, there is no justification to replace fructose with glucose because there is no evidence of net harm," said Dr. John Sievenpiper, a researcher in the Clinical Nutrition and Risk Factor Modification Centre of St. Michael's.
Using data from previous research trials, Dr. Sievenpiper and his team compared the effects of fructose and glucose against several health risk factors. The study found that consuming fructose may increase total cholesterol and postprandial triglycerides, a type of fat found in blood. However, fructose did not appear to affect insulin production, other fat levels in the blood stream or markers of fatty liver disease any more than glucose did.
In fact, fructose showed potential benefits over glucose in some key risk factor categories.
"Some health care analysts have thought fructose to be the cause of obesity because it's metabolized differently than glucose," said Dr. Sievenpiper. "In calorie-matched conditions, we found that fructose may actually be better at promoting healthy body weight, blood pressure and glycemic control than glucose."
Fructose, a simple sugar found in honey, fruit, vegetables and other plants, is also the basis of high-fructose corn syrup – a sweetener often found in commercially prepared foods. The combination of both fructose and glucose produces sucrose, generally known as table sugar.
Dr. Sievenpiper said he feels that overconsumption, rather than a type of sugar, is one of the leading causes of obesity.
"Overall, it's not about swapping fructose with glucose," said Dr. Sievenpiper. "Overeating, portion size and calories are what we should be refocusing on – they're our biggest problems."About St. Michael's Hospital

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).
The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
