• retina
  • Recently, interest in lutein has expanded beyond the retina to its possible contributions to brain development and function. (mdpi.com)
  • In this review, we will first cover the evolution of the non-human primate model for lutein and brain studies, discuss prior association studies of lutein with retina and brain function, and review approaches that can be used to localize brain lutein. (mdpi.com)
  • Lutein appears to act as a natural eyeshade, protecting the retina against too much light. (doctors-hospital.net)
  • In the human retina, lutein is absorbed from blood specifically into the macula lutea, although its precise role in the body is unknown. (wikipedia.org)
  • Although lutein is concentrated in the macula - a small area of the retina responsible for three-color vision - the precise functional role of retinal lutein has not been determined. (wikipedia.org)
  • effects of lutein
  • Lead author Dr. Billy R. Hammond Jr. noted that the research of the effects of lutein and zeazanthin are important because "it is clear that they could potentially improve vision through biological means. (diigo.com)
  • 2016
  • The United States Lutein Industry 2016 Market Research Report is a professional and in-depth study on the current state of the Lutein industry. (mynewsdesk.com)
  • uptake
  • Our team has begun to utilize the rhesus macaque ( Macaca mulatta ) model to study the uptake and bio-localization of lutein in the brain. (mdpi.com)
  • nutrients
  • At the end of the study period, participants who had taken lutein alone or lutein plus the other nutrients showed improvements in vision, while no change in vision was seen in the placebo group. (doctors-hospital.net)
  • kale
  • Lutein is synthesized only by plants and like other xanthophylls is found in high quantities in green leafy vegetables such as spinach, kale and yellow carrots. (wikipedia.org)
  • tissues
  • Many songbirds (like evening grosbeak, yellow warbler, common yellowthroat and Javan green magpie) deposit lutein obtained from the diet into growing tissues to color their feathers. (wikipedia.org)
  • Eyes
  • 1-5,8 Furthermore, there are good theoretical reasons to believe that lutein may play an important role in protecting the eyes. (doctors-hospital.net)
  • amounts
  • The results indicated that men and women who had consumed large amounts of lutein were less likely to develop the disease. (encyclopedia.com)
  • found
  • A study reported in 2001 found that carotid arteries in those with higher lutein levels were clearer than average. (encyclopedia.com)
  • study
  • Lutein may also help to prevent the development of colon cancer, according to a study published in the American Journal of Clinical Nutrition in 2000. (encyclopedia.com)
  • A subsequent study failed to find benefit with lutein, but it used a lower dose (6 mg daily) and involved fewer people. (doctors-hospital.net)
  • 15 Ultimately, further study will be needed to establish whether lutein is actually helpful for macular degeneration. (doctors-hospital.net)
  • role
  • Only primates accumulate lutein within the brain, but little is known about its distribution or physiological role. (mdpi.com)
