Research from Monash University reveals that what a mother eats during early pregnancy can have a significant impact on the brain health of her children and grandchildren. The study, conducted using genetic models, identified certain foods that can protect against the deterioration of brain function. This groundbreaking discovery highlights the importance of a healthy diet during pregnancy for optimal brain development and health.

Apples and Herbs

The research team focused on roundworms as a genetic model because they share many genes with humans. By studying these worms, the scientists gained valuable insights into human cells. They discovered that a specific molecule found in apples and herbs, such as basil, rosemary, thyme, oregano, and sage, plays a crucial role in reducing the breakdown of communication cables in the brain.

The brain contains nerve cells that communicate with each other through axons, which are like cables extending throughout the organ. In order for the brain to function properly, these axons need to be in good condition. The researchers found that a malfunction causing the axons to become fragile resulted in brain dysfunction and neurodegeneration.

Using a genetic model with fragile axons, the team explored whether natural products found in the diet could stabilize these axons and prevent breakage. They discovered that a molecule called ursolic acid, present in apples and herbs, reduced axon fragility. Through further investigation, they found that ursolic acid activated a gene that produced a specific type of fat called a sphingolipid.

This sphingolipid improved axon transport and overall health, preventing axon fragility as the animals aged. Additionally, the researchers noted that this type of fat needed to travel from the mother’s intestine to her eggs in the uterus for it to protect the axons of future generations. Although these findings are significant, they still need to be confirmed in human studies.

Summary

Professor Roger Pocock, the senior author of the study, emphasized that a mother’s diet can play a crucial role not only in her child’s brain health but also in the brain health of future generations. The research supports the idea that maintaining a healthy diet during pregnancy is essential for optimal brain development and overall well-being. While more research is needed to fully understand the effects in humans, these findings offer valuable insights into the impact of diet on brain function.
