The Claim
For female adults aged 19–50 years, modeling analyses indicate that it is not feasible to construct a lowest-cost diet that meets all nutrient requirements when accounting for the bioavailability of protein, vitamins, iron, and zinc, suggesting that current recommended intakes—particularly for iron and zinc—may be unattainable through affordable, available foods under these modeled conditions.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
It might be really hard for women between 19 and 50 to get enough iron and zinc from affordable, everyday foods—even if they're trying to eat the cheapest healthy diet possible.
See the scientific wording
For female adults aged 19–50 years, it was not possible to create a modeled diet that meets all nutrient requirements at lowest cost when bioavailability of protein, vitamins, iron, and zinc is considered, suggesting that current recommended intakes—especially for iron and zinc—may be difficult to achieve affordably with available foods under these assumptions.
What the research says
1 studyThe study shows that when your body can’t absorb all the nutrients from food perfectly, it’s harder and more expensive to get enough iron and zinc from food—especially without animal products like beef.
