A simple diet switch during pregnancy can help improve a baby’s long-term heart health, Australian researchers have discovered.
Monash University researchers have found that eating a high-fibre diet during pregnancy can significantly reduce the risk of cardiovascular disease in offspring, revealing a powerful link between what a mum eats while pregnant, and her child’s heart health for years to come.
“Dietary fibre, which is found in foods such as fruits, vegetables, and whole grains, is well-known for its health benefits,” said lead researcher Professor Francine Marques, from the Monash University School of Biological Sciences.
“Our research shows that its impact extends beyond the mother, and can shape the development of her child’s heart,” she said.
The research fed a high-fibre diet to pregnant mice and discovered that it led to healthier gut and gut bacteria in both mum and baby, reduced inflammation in the child’s heart and less scaring.
“Our work also sheds light on how fibre exerts its protective effects across generations,” Professor Marques said.
“Fibre promotes the production of beneficial molecules called short-chain fatty acids (SCFAs) in the gut.
“These SCFAs travel through the mother’s bloodstream and cross the placenta during development, where they can influence gene activity in the heart, leading to healthier heart development.”
So why is this so significant?
Because cardiovascular disease is the leading cause of death worldwide.
“This research suggests that a simple dietary change during pregnancy could have lifelong benefits for children,” Professor Marques said.
“Our work adds to the growing body of evidence highlighting the importance of a healthy diet during pregnancy.
“Expectant mothers are encouraged to discuss their diet with their healthcare providers to ensure they are getting enough fibre to support their own health and the health of their babies.”
The researchers plan to continue exploring the links between maternal diet, gut health and cadiovascular disease.
