I recently discovered that iron we get from plants is not absorbed the same way as from meat, it is actually not the exact same iron: nonheme iron (plants) and heme iron (animals).
Things can enhance or inhibit the nonheme iron absorption (vitamin C enhances, phytate inhibits, coffee/tea inhibit...), as listed in this answer.
Many people drink tea or coffee on a regular basis.
How much does it inhibit the iron absorption? Those articles it recommend to not drink coffee/tea with your meal, but 1h later/before?
I read that it is also dependent on the quantity of coffee/tea, how? Should we limit at a given quantity?
