05 Aug How A Mother’s Diet During Pregnancy Can Protect Her Baby’s Heart

Researchers at Monash University have discovered that a high-fiber diet during pregnancy can significantly reduce the risk of cardiovascular disease (CVD) in children.

Published in Circulation Research, the study highlights a strong connection between a mother’s diet and her child’s long-term heart health.

“Fibre, found in foods like fruits, vegetables, and whole grains, is known for its health benefits,” said lead researcher Professor Francine Marques. “Our research shows that its impact extends beyond the mother and can shape the development of her child’s heart.”

Key findings from the study on pregnant mice include:

• Healthier Gut: Improved gut health and microbiome in both mothers and their offspring.
• Reduced Inflammation: Lower inflammation levels in the offspring’s hearts.
• Healthier Hearts: Better heart function in offspring exposed to high blood pressure.
• Less Scarring: Decreased cardiac fibrosis (scarring) in the offspring’s hearts.

“Fibre promotes the production of short-chain fatty acids (SCFAs) in the gut,” Professor Marques explained. “These SCFAs travel through the mother’s bloodstream and cross the placenta, influencing gene activity in the developing heart and leading to healthier heart development.”

While the study was conducted on mice, the findings have significant implications for human health. “Cardiovascular disease is a leading cause of death worldwide,” said Professor Marques. “Our research suggests that a simple dietary change during pregnancy could have lifelong benefits for children.”

Expectant mothers are encouraged to discuss their diet with healthcare providers to ensure they get enough fibre for their health and their baby’s health. The researchers plan to continue exploring the relationship between maternal diet, gut health, and cardiovascular disease, aiming to provide practical dietary recommendations for pregnant women.

By incorporating more fiber into their diets, expectant mothers can take a simple yet powerful step towards ensuring their children’s heart health.
