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

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
