Purpose: To conduct a literature review related to preventing cataract through nutrition either in the form of consuming nutrient dense foods or supplements and suggest some public health policy recommendations.
Methods: A systematic literature search was performed using Web of Science and Ovid Medline, with Population, Intervention, Control and Outcome (PICO) methodology. Studies were graded depending upon strength of evidence and clinical recommendation.
Results: There are enough evidence supporting the use of multivitamins decreases the risk of cataract. Higher intakes of antioxidants and vitamins has shown a protective association with the incidence or progression of cataract.
Conclusion: Developing healthy dietary and lifestyle patterns may help to protects against cataract. A moderately strong recommendation to consume foods that are rich in antioxidants (lutein, zeaxanthin, vitamin E and vitamin C), Vitamin A, Vitamin B or multivitamin are suggested.
