A new study reveals that adding omega-3 fatty acids, such as lutein, zeaxanthin, and fish oil, to the daily intake of vitamin and minerals supplements may not help in slowing down the progression of a blinding condition called age-related macular degeneration
The study was led by Emily Chew, of the National Eye Institute in Bethesda, and involved over 4,000 people between 50 and 85 years of age over a period of five years. The researchers found that adding omega-3 fatty acids to the "AREDS" formula, short for the Age-Related Eye Disease Study, did not provide any additional benefits though removing beta-carotene and including lutein and zeaxathin not only provided a small increase in protection but also came with no increase in lung cancer risk.
"Lutein and zeaxanthin are the main components of the macular pigment. DHA is a major structural component of the retina, and EPA may play a role as a precursor to signaling molecules with potential to influence retinal function, providing biological bases for testing these nutrients", the researchers wrote in their report.
