Text: 'Out of the 600 carotenoid pigments in nature' and 'Fifty are in our diet about 20 in our bloodstream'
From Keynote lecture: Transport and retinal capture of the macular carotenoids Paul S. Bernstein, MD, PhD at 5:00 (Chart) 600 carotenoids in nature, 50 in carotenoids in diet, 20 carotenoids in serum

Text: 'Only 2 pigments enter the eye lutein and zeaxanthin'
From Macular carotenoids: an overview. John Landrum, Ph.D at 11:47 "These carotenoids are lutein and zeaxanthin in the macula pigment."

Text: '-Antioxidant -Blocking blue light -Anti-inflammatory'
From Risk factors for AMD and their relationship with the macular carotenoids Tos Berendschot, Ph.D at 01:55 (from chart) Macular Pigment: scavenger free radicals, blue light filter, inhibitor of inflammation

Text: 'Lutein: -Leafy greens and herbs rich sources -Cooked spinach 12 mg/100 g -Can covert to meso-zeaxanthin' and 'Zeaxanthin: -Cooked scallions and orange peppers top sources -Eggs and corn products good sources'
From Dietary sources of the macular carotenoids Elizabeth Johnson, PhD at 28:42 (from chart) Food sources: Lutein: green leafy vegetables, herbs. Zeaxanthin: corn and egg products.
Spinach lutein and scallion/orange pepper zeaxanthin amounts from Journal of Food Composition and Analysis
And Macular carotenoids: an overview. John Landrum, Ph.D at 17:56 "There's the central pigment here's the ratio, this is where zeaxanthin dominates, if we map meso-zeaxanthin to zeaxanthin ratio here we find the central part of the retina meso-zeaxanthin is most abundant. That's the place it's produced most. So what going on, is we believe and we propose a conversion of lutein to meso-zeaxanthin which is not occurring very efficient out here but is occurring very efficiently here. And as lutein coverts to zeaxanthin this ratio should of course change...That was shown by Liz Johnson..."

Text: 'Better bioavailability with butter'
From Effect of type of TAG fatty acids on lutein and zeaxanthin bioavailability. In conclusion, dietary fats rich in SFA lead to a higher bioavailability of lutein and zeaxanthin, as compared with fats rich in MUFA and PUFA. This is due partly to the higher bioaccessibility of these xanthophylls in the smaller mixed micelles produced when SFA are incorporated into mixed micelles.
And ILSI NA: FNSP - Emerging science on lutein and the brain (Liz Johnson, PhD) Elizabeth Johnson, PhD at 20:35 "And the only way lutein gets anywhere is on a lipoprotein, that's the only way you find it in circulation. So that's how it's going to get to tissues and most of it is going to be on HDL, that's the good one."

Text: 'Aim for 6 mg Lutein/Zeaxanthin a day'
From Dietary sources of the macular carotenoids Elizabeth Johnson, PhD at 28:42 (from chart) Intakes: -Lutein and Zeaxanthin intakes globally are 2 mg a day -Intakes 6 mg a day are related to decreased risk of AMD
At 28:59 "It's really that 6 mg that we want to aim for."

Text: 'Increased lutein decreases the risk for incurable Age-related Macular Degeneration '
From Risk factors for AMD and their relationship with the macular carotenoids Tos Berendschot, Ph.D at 00:29 (AMD POV image) "This is what AMD is and in the end this is what our patients experience. There's no real cure, so prevention that's a really important issue and that's what we're all here for."
At 00:48 (paraphrase) This is the original paper of Johanna Seddon, how can you prevent and she in 1994 already. When I was entering this field as a matter of fact. She came up with this study where she showed that having a lot of spinach, decreases your risk for AMD and then when they look for the ingredient causing this they came up with lutein...
