The Sugar Spike and the Afternoon Slump: What’s Really Going on with Our School Meals?

I grew up in the era of Turkey Twizzlers and "fishy feet." My school lunch tray was a beige landscape of chips, curly fries, and apple crumble. Even my packed lunch felt "normal" at the time: a white bread sandwich, a packet of crisps, a chocolate bar, and a piece of fruit. Balanced and healthy, right?

I was part of the Jamie Oliver rebellion. I remember vividly the work he put into changing school meals. But as a teacher standing on the frontline in 2026, I have to ask: where are we now?

The View from the Classroom

In my school, I see the reality of "healthy" school meals at ground level. A little over a year ago, we had our own chef cooking from trust-approved recipes. On paper, it looked fine. In reality, it was a processed cycle of pizza, white pasta, and "All Day Breakfasts" with grey, premade omelettes.

As a vegan, the "alternative" is usually just the same meal with a Quorn nugget or a veggie finger swapped in. It’s processed, artery-clogging, and frankly, a load of rubbish.

The "Hidden" Saboteur: The Dessert Culture

The worst part isn't even the main course; it’s the mandatory sugar hit. Every single meal is trailed by dessert (often cake or another sugary sweet treat accompanied by custard, cream, or ice cream). We are filling these children with refined sugars, watching their blood sugar spike, and then trying to teach through the inevitable crash 30 minutes later.

Our Greatest Failure: The Only Meal of the Day

This isn't just about classroom management. For many of the children I teach, their Free School Meal is the only hot, nutritious meal they get in a day. When that meal consists of processed meat and a sugary sponge cake, we are failing them at the most fundamental level. If the one meal they rely on for survival is setting them up for a health crisis and a learning slump, we are effectively locking them into a cycle of underachievement.

How We Compare: The Global Gap

Looking at my classroom, it’s hard not to feel that the UK is lagging behind. When you look at how other countries treat lunchtime, the difference in "food culture" is staggering:

Country	Approach to School Meals	Impact on Learning
Japan	The Gold Standard. Meals (Kyushoku) are made from scratch; kids serve each other and learn food origins.	Lower obesity rates; high focus and discipline in afternoons.
Finland	Universal & Free. Every child gets a balanced hot meal (since 1948). It’s considered a "pedagogical tool."	Consistently high PISA rankings; minimal "attainment gap" between rich and poor.
France	Culinary Education. Multi-course meals with fresh veg and cheese. No "vending machine" culture.	Children develop a "refined palate" early; fewer issues with "fussy eating."
UK (2026)	The Struggle. Highly processed alternatives and "dessert-first" culture despite strict-on-paper standards.	Significant "sugar crashes" affecting afternoon behaviour and concentration.

Finding a Balance

We recently switched to a company that sets, cooks and delivers the menu. The menu is more adventurous (think Cajun jambalaya, pesto pasta), but the sugary desserts remain. We need to find a way to stabilize what’s on those trays. We need whole food ingredients that limit refined carbohydrates, processed foods and meats on the World Health Organisation's (WHO) carginogen list.

Where is Jamie Now?

Jamie is still out there, but the "rebel" has become a strategist. He is currently pushing for the Good School Food Awards 2026, celebrating the chefs who actually get it right. He’s also lobbying for stricter enforcement of nutritional standards. As I’ve seen, "following the rules" often just looks like a vegan cake instead of a dairy one—it’s still a cake with a sugar hit.

What Can We Do?

• Educate on the "Crash": Teach kids about the sugar spike so they understand why they feel irritable after lunch.
  

• Demand Better Standards: Hold catering companies accountable for more than just "ticking a box."

  
  

Our children are taking these school meals as the "model" for healthy eating. If we don't change the model, we can't expect the behaviour in our classrooms to change either.
