Hyperactivity, attention deficit disorder, dyslexia and antisocial or aggressive behaviour in children can be traced back to what they eat. According to Dr Neil Ward from the University of Surrey’s Chemistry department, some children can react to the additives, preservatives and colourants in food products, causing certain behavioural problems. “Parents should identify the products which cause the reaction and eliminate it from the child’s diet,” he said.
Dr Ward monitored groups of children in schools. He aimed to find out whether behavioural disturbance linked to chemicals appeared in isolated groups or if all children were at risk. He found that certain colourants could lead to an adverse reaction within 30 minutes of consumption. He identified toxic metals like lead and aluminium and food colourants as the main culprits. Reactions to these chemicals included behavioural or body reactions like rash or physical impairments.
Finding a direct link between certain chemicals and health problems can be a difficult task. Scientific data is needed to prove that some chemicals can cause behavioural problems, but at the moment it is up to scientists to prove this. Drug companies are required by law to provide extensive human trial tests on their produce to show that it is safe to use, but the same does not apply to food producers. In the UK, children’s food are only regulated in their first year, after which it disappears. Food producers often direct their food at certain groups, including pregnant women or the health conscious, but they don’t need to provide scientific data that the products are suitable for these groups.

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...
