I was struck by the statement in the first paragraph describing the sources of lutein: green leafy vegetables, flowers, egg yolk, and animal fat. This struck me as so glaringly obvious when I connected this with a prior sentence in the same paragraph explaining that lutein binds to fatty acids. Well, then of course lutein should be found in animal fat-grazing animals (cows, sheep, goats, etc.) eat grass and leafy greens, they consume the lutein which after entering their system binds to fatty acids, which then get deposited in animal fat! This logical sequence was something I probably would never have made if I just read the paragraph without thinking about it. But my training in science, and more recently, my reading of Taubes' GCBC which discussed how animal fat is loaded with vitamins and minerals AND with a lot of mono-unsaturated fat (fatty acids) prepared my mind for this logical inference. I had salad and steak for dinner last night. I feel great this morning. I can't wait to get my next physical and see what my blood lipid profile looks like.
