Lutein and Zeaxanthin in raw and cooked vegetables
- Beschreibung
Lutein and zeaxanthin can be found in yellow-orange food, such as egg yolk and corn but especially in dark green vegetables. Intake from dietary sources is strongly associated with plasma concentrations. Indeed, it has been shown that in humans every 10% increase in dietary lutein corresponds to a 2,4% increase in serum lutein concentration. In human body lutein and zeaxanthin is stored in the eye (retina, rod outer segments, and lens) and other places in human body including skin, brain, and breasts. Sustained supplementation of lutein and zeaxanthin was demonstrated to be effective in increasing macular pigment, contrast sensitivity, and visual function in early age-related macular degeneration (AMD). These two carotenoids showed also beneficial effects on visual performance in various retinal diseases. We would like to look at the lutein and zeaxanthin levels in both raw and cooked vegetables and how they can contribute to the human diet.
