Is it true that sugar can make my toddler hyperactive?

If you've seen your toddler bouncing off the walls at a party, you can be forgiven for thinking that sugar must be the culprit. The truth is that sugar alone is unlikely to make your toddler seem hyperactive.

Toddlers are bundles of energy with short attention spans. In other words, your toddler's easily excited. If it's a special occasion, such as a birthday or Christmas, he may be happy and animated anyway. Even before gorging on sweets!

However, there is evidence to suggest that large amounts of sugar may affect some children. This is because refined and processed sugar enters your toddler’s bloodstream quickly, causing a surge in blood sugar (glucose) levels. This is usually followed by a period of tiredness.

Regardless of whether or not sugary foods affects your toddler's behaviour, it's best to keep them to a minimum. This is for several reasons, including:

  • Sugary treats and drinks don't provide many vitamins or minerals. But they may fill your toddler up so he has less room for nutritious foods.
  • Sugar is harmful to your child’s teeth.
  • Sweet foods given as a reward or for comfort has been linked to weight problems in adulthood.

Giving nutritious foods containing small amounts of sugar, such as fruit or yoghurt, at mealtimes is fine.

Remember that having lots of energy is normal for small children. So although it can be frustrating, try not to worry if your toddler gets overexcited every now and then. A walk and some fresh air may be all he needs to burn off any excess energy.

If you're really concerned about your toddler's behaviour, talk to your health visitor or GP. They'll be happy to reassure you.
