Is anyone else interested in this? It affects the absorption rate, so this would be very helpful in setting my own targets. Eight mg isn't enough when it's 100% from plant sources.
Great suggestion! Maybe you'd be willing to post it on the thread of "feature requests"?
Iron absorption is less on a plant-based diet d/t the presence of phytic acids/phytates. In general, a vegan's need for iron may be up to 80% higher than the general population's. However, because our bodies adjust absorption rates based on needs, vegans tend to get better at regulating their iron intake the longer they follow a plant-based diet.
If you'd like to set a custom target for iron in your database, I recommend aiming for 8-15 mg per day (aim for the higher end if you are an athlete).
