As a dietitian who works with kids, one of the biggest myths that persists is that sugar makes kids hyper.

So let's just go ahead and bust that myth:  Sugar does not cause hyperactivity. 

Clinical trials and reviews have found no significant effect of sugar (sucrose) consumption on behaviour.

So let's explore what might be going on: 

Sugar when consumed on its own, does not stick around for a very long time - meaning hunger creeps in sooner. This means children can enter "hangry" territory (ie: dysregulated) more quickly. This happens to everyone - not just kids! So make sure sugary foods do not replace planned meals and snacks, but rather are provided as an extra.

There is also some expectancy weaved in, meaning that likely because this myth abounds - there is some expectation of hyperactivity - so there may be an unconscious seeking to confirm a point of view (this is called confirmation bias).  Furthermore, we are all human so it is ingrained within us to notice what is not going so well and fixate mostly on that (this is called negativity bias).

But yes- it's true- kids can get excited and have big boisterous behaviours after having consumed sugary foods - so if not caused by sugar - what could be going on?

If we think of times when sweets are readily available, this might be parties, holidays, fairs, etc.. These are busy settings where kids are often excited (it's a fun celebratory time!) and on top of it all - there might be change in routine, kids might be staying up late, or have missed (or refused!) naps. So it would be anticipated to expect more energetic expressions!

I hope this information has been insightful and helpful. Is there another nutrition myth you'd like me to tackle? Email me your thoughts at [email protected]
