Father's Diet and Child Health: How Preconception Health May Shape Future Heart Disease Risk
When people think about pregnancy health, attention is usually focused on mothers. But growing evidence suggests a father's health before conception may also have lasting consequences for his family's future wellbeing. What if improving a father's health before conception could help protect the long-term health of both mother and child?
That's the question being explored by Dr Anna Ponnampalam at the University of Auckland, whose AMRF-funded project is investigating how a father's diet may influence heart health across generations. Her co-investigator Dr Ben Albert was recently featured on Radio New Zealand
While the impact of maternal health on pregnancy and child development is well established, growing evidence suggests fathers also play an important role. Research together with collaborators is showing that offspring of fathers exposed to a high-fat, high-sugar diet were more likely to experience increased body fat, higher blood pressure and metabolic changes linked to future heart disease, even when the offspring themselves consumed healthy diets.
The project started in 2025 with specialised training and study preparations, and several important milestones have already been achieved. Anna has completed advanced training in pregnancy imaging, the study protocol has been finalised, and a Master's student has joined the project and begun training.
The project is already generating new knowledge, with multiple research publications helping to build the evidence around how parental health can shape long-term cardiovascular and metabolic health. These early findings have also produced valuable preliminary data, enabling the team to pursue additional funding that could further extend the reach and impact of this important work
The research is exploring how a father's diet affects the placenta, the mother's cardiovascular adaptations during pregnancy, and the development of the baby's heart. The team will also investigate whether improving a father's diet before conception can reverse some of the risks associated with poor nutrition.
This life-course approach is particularly important because cardiovascular disease remains one of New Zealand's leading health challenges. By understanding risk factors that begin before birth, researchers hope to identify opportunities for earlier prevention and healthier futures for families.
AMRF funding is helping Anna pursue an innovative area of medical research that has the potential to reshape how we think about preconception health. Donations to AMRF also support the development of emerging researchers through student training and mentorship.
Thanks to AMRF supporters, researchers are investigating new ways to reduce cardiovascular disease risk before it begins, helping to create healthier futures for the next generation.
