A new long term study, led by Professor Henry at Oxford Brookes University, UK, has shown that children eat approximately 60 kcal less during the day following a low-GI breakfast, than after a high-GI breakfast, equivalent to reducing calorie intake by 1800 kcal over a month. This provides encouraging evidence that a low-GI start to the day may be a good option to keep obesity at bay in the young.
Thirty-eight children aged between 8–11 years (11 boys, 27 girls), were randomly divided into two groups and ate either a low-GI breakfast or a high-GI breakfast (carefully matched for calories, fat, protein, carbohydrate and dietary fibre content) on two non-consecutive weekdays over 10 weeks. The children’s food intake was monitored on the study days and on two other days each week, one of which was a weekend. The groups then swapped over for a further 10 weeks.
Sharing their findings in the September edition of the British Journal of Nutrition, the researchers noted that on average, the children ate 61 kcal less over the days when they were given a low-GI breakfast, compared with the days when they received a high-GI breakfast. Although this difference could have happened by chance, if confirmed, it would amount to a useful contribution to weight control. Interestingly, during the ten week period when the children were receiving the low GI breakfasts two days per week, they also ate less on the other days, when they were choosing their own breakfast. Professor Henry of Oxford Brookes University said: ‘Most long-term studies examining the effects of GI on food intake have been conducted in adults; this is the first to investigate its effects in children.’ He added: ‘although a difference of 61 kcal per day may not in itself seem significant, it represents a reduction of 1830kcal over a month. The difference in energy intake suggests that the children felt fuller for longer after consuming a low-GI breakfast’.
This study was unique in carefully matching the foods given for the high and low GI breakfasts to ensure that differences in protein, fat, carbohydrate and, especially dietary fibre, did not obscure the effects of the differences in GI. The results are consistent with other studies but the effects seen were smaller, probably because dietary fibre intake was more closely matched. Nonetheless, the results give further weight to the suggestion that a low GI diet may be a useful strategy to reduce the risk of overweight and obesity in children.

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
