The Claim
The Food Compass scoring system does not incorporate adjustments for the bioavailability of iron and zinc influenced by food matrix components such as phytates and vitamin C, resulting in inaccurate evaluations of nutrient adequacy in plant-based diets and populations with high phytate intake.
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.
The Food Compass nutrient scoring system ignores how certain plant compounds reduce the absorption of iron and zinc, leading to incorrect assessments of nutrient adequacy in diets high in plant foods.
See the scientific wording
Food Compass does not account for differences in bioavailability of iron and zinc based on food matrix components like phytates and vitamin C, which may lead to inaccurate assessments of nutrient adequacy in plant-based diets and populations with high phytate intake.
Phytates in plant foods bind to iron and zinc, preventing them from being absorbed in the gut. Vitamin C helps pull iron into the body, but when it's missing, even iron-rich foods don't supply enough of the mineral. This means the body gets less iron and zinc than the food label suggests, leading to nutrient gaps even when diets look adequate on paper.
What the research says
1 studyStudy: Limitations of the Food Compass Nutrient Profiling System.
The study says Food Compass treats all foods the same, even when some nutrients in plants are hard for the body to absorb — like iron in beans — and it gives high scores to sugary fortified cereals, which is misleading. So yes, it doesn’t account for real absorption differences.
