Except that pretty much no plants bioaccumulate lead. The biggest lead vector for plant-based food is the soil that hitches a ride on the outside. So peeling potatoes, carrots, beets etc and washing your other fruits and veggies is really all that is needed.
It's actually a little unfortunate that no plants we know of will take up lead because this would be a way to clean up soil. Plant a lot of plant X. Pull out the plant and discard. Repeat until the lead has been pulled out of the soil.
Some kinds of mushrooms take up lead And other toxic materials.
I only found this out because edible mushrooms grew in my yard, but they are warned in literature that they may contain heavy metals, as my well water contains 3ppb lead I wasn’t confident to eat them.
