Future diets will be short of micronutrients like iron — it’s time to consider how we feed people
In New Zealand, 10.6% of women aged 15-18 and 12.1% of women aged 31-50 suffer from iron deficiency.
- In New Zealand, 10.6% of women aged 15-18 and 12.1% of women aged 31-50 suffer from iron deficiency.
- As more people consider switching to plant-based diets, the risk of iron deficiency will likely increase.
- We argue that fortifying foods with iron could provide a one-stop solution to bridge nutrient gaps caused by inadequate dietary intake.
Food fortification
- Many foods in supermarket shelves, including common staples such as bread and cereals, already have added nutrients.
- Unlike mandatory iodine and folic acid fortification of bread, there is currently no government initiative to encourage or mandate iron fortification in New Zealand.
Shift to plant-based diets
- More consumers are opting for diets that include fewer animal-sourced foods in the hope of reducing environmental impacts and emissions.
- Recent statistics show a 19% increase in the adoption of vegan and vegetarian diets among New Zealanders from 2018 to 2021.
- Considering these plant-based diets for a sustainable food system must involve conversations about nutrient availability.

Is NZ ready for iron-fortified foods?
- Given the importance of adequate dietary iron intake and the projected shortage in dietary iron, it is crucial to evaluate the benefits of fortification.
- Educational interventions such as promoting awareness of iron deficiency and positive impacts of fortification may help improve consumers’ acceptance of these initiatives.
- Mahya Tavan receives funding from the Global Dairy Platform for developing a dietary optimisation model called The iOTA Model.
