The Nutrients Kids Miss When They Skip Breakfast

Nutrition researchers use the term 'shortfall nutrients' for the vitamins and minerals kids most commonly fall short on — and breakfast turns out to be a disproportionately important source of several of them.

Nutrients rarely made up later

A recurring finding in pediatric nutrition research: kids who miss iron, calcium, and vitamin D at breakfast tend not to make up the gap at lunch or dinner. Breakfast isn't just one of three meals nutritionally — for these specific nutrients, it's often the meal doing the most work.

Why protein at breakfast matters

Research published in nutrition science journals has linked protein-containing breakfasts to improved satiety — kids stay full longer, which in practice means less mid-morning hunger competing with their attention in class.

Why fiber matters too

A breakfast that's mostly fast-digesting sugar (think: juice and a pastry) tends to produce a quick energy spike followed by a crash. Fiber slows that process down, which is part of why nutrition guidance for kids' breakfasts emphasizes fiber alongside protein, not sugar alone.

Where a fortified option can help

For kids who eat a limited variety of foods in the morning, a fortified breakfast option can help close some of this gap without requiring a big plate of food. Kiddos+ Morning Mix provides 25 vitamins and minerals — including iron, calcium, and vitamin D, the specific shortfall nutrients this research repeatedly flags — plus 3g of fiber and 13g of protein per serving, sweetened with monk fruit and agave rather than artificial sweeteners. It's formulated for ages 8–15.
