BackgroundLutein and zeaxanthin are thought to have beneficial effects on protecting the lens against cataract formation, but findings from epidemiologic studies have been inconsistent. We aimed to conduct a meta-analysis of prospective cohort studies to examine the association between dietary lutein and zeaxanthin intake and risk of age-related cataract (ARC).MethodsWe systematically searched MEDLINE, EMBASE, Web of Science, and Cochrane Library databases up to March 2013.

Association between dietary carbohydrate intake and dietary glycemic index and risk of age-related cataract: a meta-analysis.

The results indicate that higher dietary carbohydrate quantity and GI may be associated with the risk of cortical and nuclear cataract, respectively.

Fruit, vegetable, and dietary antioxidant intake and age-related cataract risk: A case-control study

High daily intakes of fruit and vegetables and some dietary antioxidants might be associated with a decrease of cataract risk in Tehran, Iran.

Association Between Dietary Carbohydrate Intake and Dietary Glycemic Index and Risk of Age-Related Cataract:

It is indicated that higher dietary carbohydrate quantity and GI may be associated with the risk of cortical and nuclear cataract, respectively.

Dietary guidance for lutein: consideration for intake recommendations is scientifically supported

Based on a review of the literature supporting these criteria, lutein is ready to be considered for intake recommendations.

Physical activity and risk of age-related cataract.

The findings from this Meta-analysis provide additional evidence that increased physical activity is inversely associated with ARC risk dose-responsively and suggest that studies using metabolic equivalent per day tended to report a slightly stronger association with ARC.

Effect of Multiple Dietary Supplement Containing Lutein, 
Astaxanthin, Cyanidin-3-Glucoside, and DHA on Accommodative Ability

This study shows that multiple dietary supplement containing lutein, astaxanthin, cyanidin-3-glucoside, and DHA has effect to improve accommodative ability and subjective symptoms related to eye fatigue.

Lutein and Zeaxanthin Isomers in Eye Health and Disease.

  • 2016
Accumulating evidence about variable interindividual response to dietary intake of these carotenoids, based on genetic or metabolic influences, suggests that there may be subgroups that benefit from higher levels of intake and/or alternate strategies to improve lutein and zeaxanthin status.

Egyptian Vegetables as Source for Lutein and its Role in Incidence of Cataract in Rats

It is noticed that feeding on lutein diets increased the serum antioxidant enzymes and reduced the proteases activities in rats lenses compared with cataract group and thus its role in reducing the incidence ofCataract.

Diets rich in lutein and zeaxanthin are moderately associated with decreased prevalence of nuclear cataract in older women, and other protective aspects of such diets may in part explain these relationships.

The results suggest that the use of high-dose (but not low-dose) single vitamin C or E supplements may increase the risk of age-related cataract, and the risk may be even higher among older men, corticosteroid users, and long-term users.

An inverse association between high dietary LZ intake and prevalence of nuclear cataract is found and is similar to that found in previous studies of cortical, nuclear, and PSC cataracts.

Results of this short term follow-up study are consistent with a possible protective influence of lutein and vitamins E and C on the development of nuclear cataracts, but evidence in the present study provides weak support for these associations.
