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.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
