On a recent episode of Newstalk’s Alive and Kicking, pharmacist and Meagher’s Pharmacy Group Managing Director Oonagh O’Hagan joined Clare McKenna to discuss carotenoids, inflammation, and why understanding what’s happening inside the body can be a powerful first step towards better long-term health.
Carotenoids: Nature’s Protective Pigments
Carotenoids are naturally occurring pigments found in brightly coloured fruit and vegetables. In plants, they help protect against damage from light and oxidative stress. In the human body, research has shown that three specific carotenoids accumulate in the eye and brain: lutein, zeaxanthin, and meso-zeaxanthin.
LifeMeter Screening: A Snapshot of Nutritional Status
During the interview, Oonagh explains how non-invasive LifeMeter carotenoid screening offers a snapshot of nutritional status by measuring carotenoid levels in the skin, a recognised indicator of levels in the blood, eye, and brain. The LifeMeter test takes just one minute and can help people understand whether their diet is providing enough of these nutrients.
Research on Macular Pigments, Brain Health, and Ageing
The conversation also highlights the growing body of research led by Professor John Nolan at the Nutrition Research Centre Ireland, which has explored the relationship between macular pigments, cognitive health, and ageing. His work has helped to deepen understanding of how targeted nutrition, alongside lifestyle factors such as sleep, movement, and stress management, may support brain and eye health over time.
Empowerment Through Nutrition
A key takeaway from the discussion is empowerment. Rather than fear or finger-wagging, LifeMeter carotenoid screening can act as a practical starting point, encouraging people to increase colour diversity on their plate and make informed choices about nutrition as part of a broader lifestyle approach.
