Children`s disruptive behaviour can be linked to food choice

16.04.2002


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.


There has been a decrease in the general health status of children, with more children being classified as obese. GPs have also noted an increase in the number of complaints about asthma, sore throats or skin rashes, which could all be traced back to chemicals in food.

“Children in primary schools are under a lot of peer pressure to consume certain products,” Dr Ward said, “and they tend to favour products containing a lot of sugar. The problem is that these products often also contain some ‘nasty’ chemicals.”

“Consumers often don’t understand the information on food labels. They were a bit more conscious of labels when concerns about e-numbers was first raised, but since organic food hit the shelves, people seem to think everything is safe now,” he said.

“It is very important that not only children but in many cases their parents should be encouraged to learn more about the foods they choose to consume, how they are stored, prepared and cooked in terms of providing optimum nutritional value to their diet,” Dr Ward concluded.

Im Focus: Physicists Design Ultrafocused Pulses

Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.

Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers

Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...

Im Focus: Flexible proximity sensor creates smart surfaces

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.

At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
