i dare you to do a side by side comparison
of human blood to chlorophyl .... they are
almost identical,
the difference is.... just one Element.. chlorophyl has manganese
and blood has magnesium... so when you eat anything
green
you only need adequate magnesium in your diet
(i take suppliments) to make brand new blood.
its the fountain of youth ....... literally 
which is why i grow a shet load of sugar snap peas!!!
