A review of scientific evidence found only a minority of children were actually affected by what they eat. A combination of food, genetics and environmental toxins are more likely to be involved, with no single factor to blame.
Foods which might affect behaviour, in particular table sugar were studied. No adverse effects were seen in children who had a sugary drink versus a drink with artificial sweetener. Parents often believe their children’s diet is making them hyperactive and think changes in the food provided is the answer to the problem. However changing your child’s diet is not likely to settle their over active behaviour.
ADHD (attention deficit/hyperactivity disorder) has a strong genetic link, with half the children born of parents with diagnosed ADHD likely to develop the disorder themselves. Chemical imbalances in the brain are also involved and studies have found that children with the condition have on average 4% smaller brains. Genes may interact with environmental toxins such as alcohol in the womb, lead, and parental smoking to cause later problems with attention span.
Professor David Benton, who specialises in eating behaviour and who carried out the study said ‘Parents say after an hour of eating sugary foods that their child is distracted and fidgety, but studies show that this is more what the mother expects to see and not what’s really going on’. He added ‘the origin of the idea that sugar is responsible for hyperactivity seems to be purely based on the fact that sugar is a source of energy, as are other carbohydrates. Foods like wheat and dairy can often cause food intolerance in children, but this is a completely different reaction of the immune system.’
This review which was carried out at the University of Wales, Swansea is published in the May issue of the journal Critical Reviews in Food Science and Nutrition. It comes at a time when the Food Standards Agency is looking at other causes of hyperactivity in children with a call to remove certain additives in foods.
Up to 9% of children in the U.K. have been diagnosed with ADHD. Problems are usually seen at around 4 years of age when the child may become easily distracted, fidgety, and impulsive over a long period of time.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
