The first report found that: the risk of age-related macular degeneration with increasing serum concentration of lutein significantly reduced. The second report found that: the crowd of lutein intake of the highest (6mg) and the lowest intakes (2mg) population compared to the risk of age-related macular degeneration is significantly reduced. In the dietary survey results found that regular consumption of spinach and kale (the richest dietary source of lutein) can also reduce age-related macular degeneration risk. The survey results of two studies are fairly consistent, suggesting that age-related macular degeneration and lutein intake has a direct relationship.
