A carefully controlled animal study provides clear evidence that a low-glycemic-index (low-GI) diet – one whose carbohydrates are low in sugar or release sugar slowly – can lead to weight loss, reduced body fat, and reduction in risk factors for diabetes and cardiovascular disease.
"The study findings should give impetus to large-scale trials of low-GI diets in humans," says senior author David Ludwig, MD, PhD, director of the Optimal Weight for Life (OWL) obesity program at Children’s Hospital Boston. His group’s findings appear in the August 28th issue of The Lancet.
Many studies, including small studies in humans, have suggested that low-GI diets are beneficial, but due to study design, the observed benefits could have come from other aspects of the subjects’ diets, such as fiber or overall caloric intake. For this reason, no major health agency or professional association references glycemic index in their dietary guidelines, Ludwig says.

Goodbye, silicon? On the way to new electronic materials with metal-organic networks
17.10.2018 | Max-Planck-Institut für Polymerforschung
Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz (Germany) together with scientists from Dresden, Leipzig, Sofia (Bulgaria) and Madrid (Spain) have now developed and characterized a novel, metal-organic material which displays electrical properties mimicking those of highly crystalline silicon. The material which can easily be fabricated at room temperature could serve as a replacement for expensive conventional inorganic materials used in optoelectronics.
Silicon, a so called semiconductor, is currently widely employed for the development of components such as solar cells, LEDs or computer chips. High purity...
Augsburg chemists present a new technology for compressing, storing and transporting highly volatile gases in porous frameworks/New prospects for gas-powered vehicles
Storage of highly volatile gases has always been a major technological challenge, not least for use in the automotive sector, for, for example, methane or...
When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.
We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
