Are our children well fed? In kilojoules, almost always. In nutrients, often not. National surveys keep returning the same uncomfortable finding: fewer than 1 in 10 Australian children eats the recommended amount of vegetables, and discretionary foods, the chips-biscuits-and-soft-drink category, supply around 40% of children's daily energy. None of that means you are failing. It means a modern food environment plus a normal fussy phase leaves gaps worth measuring, and measuring them is exactly what nutritional deficiency work is for.
Key takeaways
- Most Australian children get plenty of energy and not enough of specific nutrients, and the 2 problems look identical at the dinner table.
- Fewer than 1 in 10 children meets vegetable recommendations in national surveys, year after year.
- Iron, zinc, vitamin D, omega-3 and fibre are the gaps we see most, and their warning signs are frustratingly non-specific.
- Fussy eating is a normal developmental phase that the modern snack aisle makes stickier.
- Test first, supplement second: data beats a multivitamin bought on a hunch.
What the national surveys keep finding
Survey after survey tells the same story. Vegetables are the headline shortfall: most children eat some, but the typical intake sits at a fraction of the recommended serves, and the proportion of children actually meeting the guideline has stayed stubbornly tiny across successive national surveys. Fruit fares better. Meanwhile discretionary foods quietly supply about 4 in every 10 kilojoules children eat, which crowds out the foods that carry iron, zinc and fibre. This is why "he eats heaps" and "is he well fed" are different questions: a child can be full, growing and still running light on the nutrients that concentration, mood and immunity draw on. The drift is structural rather than moral, too. Discretionary foods are engineered to be easy, school canteens and birthday seasons exist, and the packet snack colonised the lunchbox within a single generation of parenting.
Surveys describe populations, though, not your child. 2 better starting points: map a typical week of eating with the free nutrition gap checklist, which takes about 2 minutes, and where the diet is genuinely narrow, nutritional testing shows what that diet is actually delivering, measured rather than assumed.
The fussy-eater reality: what 19 years of intakes shows
Ask a clinic to name the patterns it hears most and you get a familiar cast. The beige rotation: toast, pasta, nuggets, crackers, the 1 acceptable banana. The milk-fills-the-tank toddler, drinking a litre a day and eating like a sparrow. The snack-grazer who is never hungry at meals because the eating never actually stopped. The sauce-separatist, the brand-detective who can identify the wrong nuggets through the oven door, the child whose accepted list shrank after a vomiting bug and never recovered. After 19 years of intake appointments, none of this raises an eyebrow at ReMed, and none of it gets judged.
2 things are true at once. Fussy eating is developmentally normal, usually peaking in the toddler-to-primary years, and pressure tactics reliably make it worse. And a genuinely narrow, beige-heavy diet can still leave real gaps that deserve attention rather than hope. The kind question is not "why won't this child eat properly". It is "across the foods this child does accept, what is their body getting enough of, and what is it missing?" That is a measurable question.
The nutrients that go missing first
Iron leads the list: it is among the most common nutritional gaps in Australian children, the classic casualties of a low-meat, high-milk or beige diet, and its symptoms, fatigue, pallor, poor concentration, irritability, look like a dozen other things. Iron is also a topic Keonie Moore has written about for Mamamia in the context of ADHD, because ferritin, the storage measure, can sit low even when a standard result looks acceptable. Zinc follows, relevant to appetite, skin and immune function, and scarce in beige diets. Vitamin D depends more on sun habits than food. Omega-3 goes missing wherever fish never lands on the plate. And fibre is the vegetable shortfall's twin, showing up as the sluggish bowel habit parents rarely connect to the dinner table. Calcium earns a mention for the dairy-refusers, as does B12 for largely meat-free households.
The pattern across all of them: signs are non-specific, so symptom-guessing fails in both directions. Parents worry about deficiencies a blood test would rule out in a week, and miss ones that have been quietly flattening the afternoons for a year.
Test first, supplement second
The supplement aisle sells certainty by the bottle, and tired parents buy it in good faith. The trouble is that generic children's multivitamins spread small doses across many nutrients, which rarely closes a genuine measured gap, and an unmeasured gap might not exist at all. So the order of operations at ReMed never changes. First the history: growth, energy, sleep, bowel habit and an honest week of eating. Then the data: iron studies including ferritin, zinc, B12 and folate, vitamin D, interpreted in clinical context alongside anything your GP has already run. If recent bloods exist, bring them rather than repeating them: good data is good data, whoever ordered it. Then the plan, which leans on food first because food does the long-term work, with targeted supplementation reserved for measured gaps, dosed properly, and re-tested rather than renewed forever. If a supplement cannot justify its place with data, it does not keep its place.
Closing the gap without mealtime battles
Nothing here requires a dinner-table standoff. Anchor breakfast with protein and iron-carriers your child already accepts: eggs, baked beans, a fortified cereal that is not all sugar. Give snacks a schedule instead of a graze, so genuine hunger arrives at meals. Keep serving 1 new food alongside the safe ones without commentary, and expect double-digit exposures before anything changes: that is normal, not failure. Protect the safe foods completely while you do it. And if your child is a big milk drinker, mention it to your GP or child health nurse, because milk displacing meals is 1 of the commonest iron stories there is.
Lunchboxes respond to structure too: 1 protein, 1 fruit, 1 crunch, 1 treat, packed the same way every evening, beats nightly invention and survives a school term. Involving your child in 1 low-stakes food job a week also pays off slowly, stirring the pot, choosing between 2 vegetables at the shop, growing cherry tomatoes, because familiarity is built in the hands long before it reaches the mouth.
When to escalate: growth that has drifted, energy that never recovers, a food list that keeps shrinking, or that quiet parental instinct that something is off. Start with your GP. Then, if you want the nutritional layer mapped properly, a 60-minute ReMed consultation (from $242) at Bundoora or by telehealth Australia-wide takes the full history and tests only what the history justifies.
