Relation between dietary intake, serum concentrations, and retinal concentrations of lutein and zeaxanthin in adults in a Midwest population
age-related macular degeneration lutein zeaxanthin
2016/6/14
Information on concentrations of retinal carotenoids
(macular pigment, or MP) is of particular interest because MP
protects against age-related macular degeneration, the leading
cause of irreversib...
Cataracts are common in older adults, affecting <55–85% of
people > 75 y of age (1, 2), so that the identification of dietary
strategies to delay their onset could have tremendous influence
on the ...
Bioavailability of lutein from vegetables is 5 times higher than that of β-carotene
antioxidants low-density-lipoprotein oxidation humans
2016/6/1
To gain more insight into the relation between
vegetable consumption and the risk of chronic diseases, it is
important to determine the bioavailability of carotenoids from
vegetables and the effect...
Lutein and zeaxanthin concentrations in plasma after dietary supplementation with egg yolk
Humans plasma lutein
2016/6/1
The food matrix in which carotenoids are found
affects their bioavailability. Lutein and zeaxanthin are abundant
in egg yolks and accumulate in the macular region of the retina,
where they may affe...
A comparison of lutein, spray-dried Chlorella, and synthetic carotenoids effects on yolk colour, oxidative stability, and reproductive performance of laying hens
carophyll alga egg quality yolk colour cooking length
2015/6/24
ISA Brown hens were fed diets supplemented with the synthetic carotenoids Carophyll Red and Carophyll Yellow at 20 and 15 mg/kg, respectively, lutein at 250 mg/kg, and the algae Chlorella at 12.5 g/kg...
Study of the Effects of Dietary Lutein on Reproductive Performances in Chickens
antioxidant carotenoid chickens lutein reproduction
2009/7/30
The aim of the present study was to determine the effects of dietary supplementation of lutein on reproductive performances in mature chickens. At 40 weeks of age, 15 Barred Rock roosters (n=5 per tre...
Effect of dietary lutein and zeaxanthin on plasma carotenoids and their transport in lipoproteins in age-related macular degeneration1,2,3,4
HDL cholesterol LDL cholesterol VLDL cholesterol retina age macular degeneration
2008/12/12
Background:Low dietary intakes and low plasma concentrations of lutein and zeaxanthin are associated with an increased risk of age-related macular degeneration (AMD). No studies have challenged AMD pa...
The role of the carotenoids, lutein and zeaxanthin, in protecting against age-related macular degeneration: A review based on controversial evidence
age-related macular degeneration (AMD) carotenoids
2008/4/23
Purpose
A review of the role of the carotenoids, lutein and zeaxanthin, and their function in altering the pathogenesis of age-related macular degeneration (AMD).
Macular pigment density in relation to serum and adipose tissue concentrations of lutein and serum concentrations of zeaxanthin
Macular pigment lutein zeaxanthin carotenoids macular degeneration Netherlands
2016/12/19
Background: Macular pigment (MP), concentrated in the central area of the retina, contains the carotenoids lutein and zeaxanthin. A low MP density could be a risk factor for age-related macular d...
Vegetable-borne lutein,lycopene,and β-carotene compete for incorporation into chylomicrons,with no adverse effect on the medium-term (3-wk) plasma status of carotenoids in humans
Carotenoids bioavailability spinach tomatoes antioxidants women
2016/12/17
Background: The results of epidemiologic studies have consistently shown associations between dietary intake or plasma carotenoid status and incidence of cancers and cardiovascular and eye diseas...
Relation among serum and tissue concentrations of lutein and zeaxanthin and macular pigment density
Carotenoids lutein zeaxanthin macular pigment adults
2016/6/7
Background: Lutein and zeaxanthin are the only carotenoids in
the macular region of the retina (referred to as macular pigment
[MP]). Foods that are rich in lutein and zeaxanthin can increase
MP de...
