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

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
