Waterford scientist links diet to better eye and brain health in ageing

Professor John Nolan of South East Technological University has released a documentary, A Vision For Vision, detailing two decades of research into how nutrition may support eye and cognitive health as people age.

The Waterford‑based researcher, originally from Tipperary, began his PhD in 2001 and soon after obtained a fundus camera to photograph the back of the eye. Early imaging of his 76‑year‑old mother, Helen, showed changes consistent with early age‑related macular degeneration (AMD), although standard vision tests recorded no decline.

Following the findings, Nolan encouraged his mother to adopt lifestyle changes, including a diet rich in carotenoids and omega‑3 fatty acids and to stop smoking. She also became one of the first participants to take a supplement containing the three macular carotenoids lutein, zeaxanthin and meso‑zeaxanthin.

Nolan reports that Helen’s vision has not worsened and her overall health has improved; she is now described as energetic, alert and actively involved in daily life despite also living with post‑polio syndrome.

In his role as director of the Nutrition Research Centre Ireland, Nolan also works with individuals affected by Alzheimer’s disease, highlighting the broader impact of cognitive decline on families.
