Behaviour and addiction
Does sugar make children hyperactive, is there a link with ADHD?
There is no evidence that sugar makes children hyperactive or that there is a link with ADHD.
Several scientific studies have been carried out to investigate a possible relationship between sugar and hyperactivity. They found that sugar is not the cause of hyperactivity. There is no evidence for a relationship between sugar and ADHD (Attention Deficit Hyperactivity Disorder). ADHD is a combination of poor concentration, restlessness, hyperactivity and impulsiveness. The disorder is largely inherited. It is not caused by sugar, preservatives or colourings.
Is sugar addictive?
Physiologically, sugar addiction does not exist. Liking sweet products, however, does exist.
Eating a lot of sugar is conditioned behaviour that is learned because we have a preference for sweet, not necessarily for sugar itself. Sugar is not addictive. Addiction is associated with compulsive desire, withdrawal symptoms and growing dependency. For example, sugar is not classified as an actual or potentially addictive substance. In conclusion, eating too many sweets is just a learned habit.
