Super maize? study checks if biofortified corn boosts nutrient absorption in guatemalan children

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether biofortified maize—corn grown to have higher zinc and iron—helps school-aged children in Guatemala absorb more of these nutrients compared to traditional maize. Fifty-six children aged 10-14 ate tortillas made from either biofortified or regular maize for 27 days. Researchers used stable isotopes to measure how much zinc and iron their bodies actually absorbed.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
biofortified maize
What this could lead to
If successful, this could show that biofortified maize is a better source of zinc and iron than traditional maize, potentially helping reduce nutrient deficiencies in regions where maize is a staple food.
What could go wrong
This is a small, completed study with only 56 children in a specific region, so results may not apply broadly. It measures absorption, not long-term health outcomes, so real-world benefits are uncertain.
