Why Some Evenings Feel Louder: The Hidden Role of Snacks
Ever noticed how some afternoons or evenings feel… louder?
More meltdowns. More “I can’t settle.” More “I’m starving again.”
Food isn’t the only reason this happens, of course. Sleep, school stress, screen time, and busy schedules all play a role. But what kids eat after school can be one important (and changeable) piece of the puzzle.
What’s Really in Many After-School Snacks?
A lot of popular “kid snacks” are ultra-processed: designed to look bright, taste intense, and last a long time in the pantry. Common examples include lollies, snack packs, flavoured milks, some muesli bars, and many packaged treats.
These foods often contain:
Artificial colours
Flavour enhancers
High-sugar syrups and refined carbohydrates
Preservatives and emulsifiers (often listed as numbers)
For some children, these ingredients may contribute to less-steady energy and more difficulty settling later in the day.
Artificial Colours and Behaviour (What the Numbers Mean)
Some research suggests that certain artificial colours—especially when combined with preservatives—may affect behaviour and attention in a subset of children. Not every child reacts the same way, but some families notice more restlessness after heavily coloured snacks.
Colours commonly listed as numbers on Australian labels include:
102 — Tartrazine (Yellow)
110 — Sunset Yellow FCF (Orange/Yellow)
122 — Carmoisine / Azorubine (Red)
129 — Allura Red AC (Red)
You don’t need to eliminate every coloured food forever. But if school nights are tough, it can help to notice how often these appear across snacks, drinks, yoghurts, and “fun” foods.
Sugar Spikes, Then Sugar Crashes
Many packaged snacks contain multiple forms of refined sugar (for example glucose syrup, maltodextrin, dextrose, fructose, rice syrup). Even when a product looks “healthy,” the ingredient list can tell a different story.
A high-sugar snack can lead to:
Rapid blood sugar spikes
Followed by quick drops (“crashes”)
Tiredness, irritability, and renewed hunger
That late-afternoon “bottomless pit” feeling often isn’t just appetite—it can be the body responding to unstable energy.
Why Protein Helps After School
Protein is one of the simplest ways to make after-school snacks more settling. It helps support steadier blood sugar and can keep kids fuller for longer.
Whole-food protein options (kid-friendly) include:
Eggs: boiled eggs, omelette strips, egg muffins
Dairy (if tolerated): Greek yoghurt, cheese, cottage cheese
Meat/fish: chicken pieces, turkey slices, tuna on crackers
Plant proteins: hummus, edamame, lentils, chickpeas
Nuts/seeds (age-appropriate): nut butter, chia pudding, seed crackers
What About Flavour Enhancers?
Flavour enhancers such as MSG (621) and disodium inosinate/guanylate (631/627) or 635 are considered safe for most people, but individuals can respond differently. Some report headaches, restlessness, or a “wired” feeling after foods high in these additives.
Again: not everyone is affected. The goal is simply awareness—so you can test what works for your child.
Simple School-Night Guidelines (Whole-Food First)
If evenings are a struggle, try a “whole-food first” approach Monday to Thursday:
Start with protein (even a small amount)
Add fibre (fruit, veg, whole grains) for steadier energy
Keep colours/additives occasional rather than daily
Choose shorter ingredient lists most of the time
Quick whole-food snack ideas (10 minutes or less)
Apple + peanut/almond butter (or sunflower seed butter)
Greek yoghurt + berries + cinnamon
Cheese + cucumber + cherry tomatoes
Hummus + carrot sticks + pita triangles
Boiled egg + fruit
Tuna + avocado on wholegrain crackers
Leftover chicken + veggie sticks
Smoothie: milk/Greek yoghurt + banana + berries (no added syrup)
This doesn’t mean banning fun foods entirely. Weekends, parties, and celebrations are part of normal life. But on school nights, gentler options can sometimes make evenings calmer for everyone.
Making It Easier to Choose
You don’t need to memorise every additive or study every label in the supermarket aisle. That’s exactly why Goodnessly was created:
Scan a product
See additive alerts and a clear score
Quickly spot calmer, steadier options for school nights
Small choices don’t solve everything—but they can make evenings feel a little quieter, steadier, and easier for the whole household.
