The Claim
Dietary models that account for nutrient bioavailability require a 50% to 89% higher daily cost to meet nutrient requirements compared to models using total nutrient content, primarily due to increased reliance on animal-sourced foods that provide highly bioavailable forms of micronutrients such as iron and zinc.
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.
If you plan meals based on how well your body can actually absorb nutrients—like iron and zinc from meat—instead of just counting total nutrients, it ends up costing 50% to 89% more each day to meet your needs.
See the scientific wording
Modeling diets based on bioavailable nutrient content increases the daily cost of meeting nutrient requirements by 50% to 89% compared to models using total nutrient content, due to the greater inclusion of animal-sourced foods needed to supply highly bioavailable micronutrients like iron and zinc.
What the research says
1 studyThe study shows that when diets are planned using nutrients your body can actually absorb, they cost more and include more meat and animal products, just like the claim says.
