Blood sugar spikes and concentration: a nutritionist’s perspective

While the brain accounts for only about two percent of the average body mass, it can use a whopping 30 to 60 percent of the incoming blood glucose from any meal.

School days have little brains working overtime, and they need a constant supply of blood glucose to fuel it.  

Teaching is also far easier without students suffering from sugar highs and sugar lows. Emotional outbursts and temper tantrums are far less likely to occur, once blood sugar levels are addressed.  

The solution is surprisingly simple. To keep a child’s blood sugar level stable, ensure a little bit of protein is consumed at every meal. The protein acts like an anchor on the meal and ensures that the energy from the meal is released slowly and steadily.

Sending out a reminder to parents can encourage the practice of sending children to school with balanced blood sugar, and the school can help prevent blood sugar fluctuations by fleshing out that healthy eating section of the canteen full of fruit with some protein.

Education about balancing meals is also useful, and provides the flow-on effect of better behaviour and improved concentration in the classroom. 

Teenagers, who are under considerable academic pressure, are particularly susceptible to emotional outbursts and brain fog, so it is well worth endeavouring to influence teenage snack habits.

If they can’t buy it on campus, they are much less likely to eat empty carbohydrates and sugary snacks at school.

Protein-rich canteen ideas:
