Should Dietary Reference Intake (DRI) Values be Developed for Lutein?
Lutein has been studied for its role in eye health and for preventing or delaying macular degeneration. Lutein is a carotenoid antioxidant found in high amounts in dark green, orange, red and yellow vegetables and fruits. According to the article by Ranard, et al., Dietary
guidance for lutein: consideration for intake recommendations is scientifically
supported, there is enough evidence to establish DRIs for lutein. This is based on lutein meeting nine criteria as described by Lupton, et al. The criteria help to determine if dietary recommendations should be established for bioactive substances such as lutein, lycopene, isoflavones, etc. For more information on eye health, including lutein, see the Eye Health Knowledge Pathway.
Additionally, the National Academies
of Sciences, Engineering and Medicine has recently published a consensus
report that outlines principles for developing Dietary Reference Intakes for nutrients and other food substances that incorporate chronic disease considerations.

New 2015-2020 Dietary Guidelines for Americans
The new U.S. Dietary Guidelines for Americans were released on January 7, 2016. Following are a few opinion articles that followed their release: The 2015 Dietary Guidelines at Long Last; Dietitians Response to the 2015 Dietary Guidelines: 'The American Public Needs More Forceful Messages'; Foodminds Infographic Shows Evolution of U.S. Dietary Guidelines; and How America's new Diet Guidelines Stack Against Australia's. While the new guidelines are designed for professionals and focus more on dietary patterns of eating, they are vague in their recommendations and may need translating for consumers to understand.
