Sugar not linked with diabetes risk

07.12.2006
It has long been suspected that a high sugar diet over a long term period may lead to an increased risk of developing diabetes. But there has been little or no evidence to support this idea, with studies on the role of any aspect of the diet in the development of diabetes difficult to conduct.

Researchers from the Royal Victoria Hospital and Queen’s University Belfast have just published the results of a clinical trial looking at the effects of high sugar intake on insulin resistance (said to be a precursor of Type 2 diabetes) and vascular health in 13 healthy nondiabetic men.

Sharing their findings in this month’s Diabetes journal, Dr Steven Hunter and his team of researchers report that those who received 25% of their calorie intake from sucrose (sugar) as part of a balanced, weight maintaining diet for 6 weeks showed no difference in their degree of insulin resistance, compared to a eucaloric (calorie matched) diet providing 10% of energy as sucrose (control).

In this study, the 25% treatment diet provided on average 200g sucrose per day compared with 80g sucrose from the control (10%) diet (around the average for a British adult).

Dr Hunter of the Royal Victoria Hospital said: ‘Sugar has traditionally been linked to the development of diabetes. These findings challenge that thinking, and show that intakes of more than double that currently recommended do not appear to have an adverse effect on markers of diabetes risk.”

The study saw 13 healthy men receive either a high-sugar diet (providing 25% of their energy) or a diet providing 10% of their energy as sugar for a period of 6 weeks. After the 6 weeks, subjects ‘crossed over’ to receive the other treatment for a further 6 weeks. Treatments were separated by a four week wash out period, during which the subjects returned to their usual diet.

The diets for each period were closely matched in overall macronutrient (carbohydrate, fat and protein) composition. The only difference was in substituting sucrose (sugar) for starch. Insulin resistance was measured by the research ‘gold standard’; a two-step glucose clamp.

Furthermore, the high sucrose diet showed no significant adverse effects on a number of other metabolic and physiologic parameters, such as elasticity of the arteries (known as vascular compliance) which impacts on risk of heart disease, and glycaemic profiles.

This study showed that an intake of sucrose two and a half times above average consumption levels showed no adverse effects on this important marker of diabetes risk. This study does not therefore support the notion that sugar intake, within a broad range that covers the intake of the majority of British adults has any adverse effect on the risk of diabetes.

Diet can have a large impact on risk of type 2 diabetes; the strongest evidence for a link exists with saturated fat. Dr Hunter advises that the best way of reducing the likelihood of developing diabetes is through lifestyle changes. He adds “It is likely that other dietary factors such as excess calories and lifestyle factors such as physical inactivity and weight gain may be more important than carbohydrate type.”

In people at risk of type 2 diabetes, a diet rich in carbohydrate and low in fat appears to offer protection against insulin resistance. In addition, being of a healthy body weight and maintaining an active lifestyle will help reduce the risk of developing type 2 diabetes.

Im Focus: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
