What research says
Animal and lab studies only
-
No harm found
Baking and mineral uptake3
In animal studies, baking bread did not help the body absorb reduced iron any better.
How it’s made and used
-
Mineral uptake in body2
In animal and lab studies, reduced iron added to wheat flour was absorbed better than another iron powder.
The signal at the top counts the findings in people and in animal and lab studies. A concern in studies of people outranks animal and lab studies, and “No concerns” needs at least two findings in people. Findings whose study type is not stated are shown but not counted. This page is a reference, not medical advice. It describes what regulators and published research say. Talk to a doctor or dietitian about your own diet.
