I have a controversial thought to share... I don't remember if it wasn't already shared on this forum...
I read somewhere that the people without talassemia (without obvious iron overload) with higher liver iron content live shorter. There even was a study.
The article read that this is another incentive not to eat meat. It also read that women are better off with their menstrual bleeding (in terms of liver iron content).
So, I was thinking if blood donation can be treated as a health enhancing procedure. Me for example, I have slightly elevated liver iron content considering my age... I should probably have this iron content in about 10-15 years, and I have it now (due to talassemia of course, although I am minor, there is this slight overload - barely noticable)...
The idea is kind of ridiculous, and you'd have to be extra careful not to eat iron containing foods after the donation in order to see the effects.
But this would allow to get this iron out of your system...
Just a thought...
About the blood donation: it is possible to donate only some portion of the blood - the red blood cells are separated and returned to the bloodstream, the other portions like platelets are used for transfusions - this assures no stress to the body, and you still get to do a good deed.
