Nutrition and Healthy Ageing in Ireland: The OASIS Study

Researchers are inviting all adults, aged 60 and over, who regularly consume bread, to join this study focused on enhancing healthy ageing through better nutrition.
The OASIS Study is an 8-week initiative offering participants healthy white and wholemeal bread loaves to support their health.
This collaborative study between University College Cork and University College Dublin is funded by the Department of Agriculture, Food, and the Marine.
Led by Prof Mairead Kiely and Prof Kevin Cashman at UCC’s Cork Centre for Vitamin D and Nutrition Research, in partnership with Dr Aifric O’Sullivan and Prof Eileen Gibney at UCD, the study explores how vitamin fortified foods can prevent the seasonal drop in vitamin D levels commonly experienced by older adults in Ireland during winter.
The study is looking to recruit 200 volunteers aged 60 and over and will run between now and March 2025. All participants must sign up by January. It includes two in-person study visits at UCC or UCD and regular phone check-ins to ensure a supportive experience for all participants.
Dr Colette O’Neill, who oversees the daily operations of the OASIS study, shares:
“The OASIS study is an essential initiative in Ireland to explore how everyday foods can promote better health and prevent vitamin D deficiency. We are excited to partner with older adults who value healthy ageing and good nutrition.”
