but iron in say...spinach has a carbon attached to the iron chain structure making it useable or assimilable by the human body.

Iron in spinach is pretty much unusable by the body because it's in a form (ferrous oxalate) that can't be absorbed. The easiest way to get iron is through eating red meat. The heme form of iron is readily absorbed.

Just how much iron do you really need? Does a body recycle iron?

Animal products are 40%, 60% assumable and/or absorbable iron. That’s about 40% heme iron and 60% non-heme iron. Lot’s of unnecessary waste there that can’t undergo digestion along with extra fat/greases that accumulate over the years to cause other diseases.

Garden picked fresh and immediately eaten spinach, all the iron is assumable. Only shelf life begins ruining the makeup of fresh foods. Steaming (pressure cooker) will aid in a body absorbing nutrients from vegetables and other foods besides the body reheating intake before breaking it down (digesting).
