Does eating too much sugar cause hyperactivity in children?
In the 1970s it was suggested that hyperactivity in children (also known as Attention Deficit Hyperactivity Disorder or ADHD) was caused by eating too much sugar. Detailed studies, however, have concluded that there is no link between sugar consumption and hyperactivity or any other type of ‘bad behaviour’ or learning difficulties. Children may become over-excited on occasions where lots of sugary foods are eaten (eg birthday parties) but this is a consequence of the situation, not their sugar intake. Sugar is a normal part of a healthy diet and it is not possible to be ‘allergic’, ‘intolerant’ or ‘sensitive’ to sugar.
