more orange yolk means less AMD blindness:
summary:
. a yolk that is more orange (than yellow)
is likely to have more lutein and zeaxanthin
that reduces the risk of AMD blindness.
. organic eggs have rules about
the coloring additives added to chicken feed.
. if you are not certain about the quality
of the coloring in your egg,
you can supplement with zeaxanthin and lutein.
[eg, MacuGuard® Ocular Support with Saffron:

10 mg free lutein,
4 mg meso-zeaxanthin & trans-zeaxanthin.]
. taking the supplement with yolk
might increase its bioavailability
because MacuGuard claims to use Phospholipids
in order to enhance lutein absorption,
and egg yolk contains Phospholipids.
