Ep 159 How Your Genetics Can Guide Your Nutrition with Dr. Steven Zeisel

Could your DNA explain why one-size-fits-all nutrition advice doesn't always work? Why do some people thrive on certain diets while others struggle, even when they're "doing everything right"? What if your genetics could help guide smarter nutrition choices before pregnancy, during pregnancy, and across your entire lifespan?

In this episode of Brave & Curious, Dr. Lora Shahine explores how genetics, nutrition, and reproductive health are deeply intertwined. She is joined by Dr. Steven Zeisel, a physician-scientist whose groundbreaking research helped redefine choline as an essential nutrient.

Their discussion traces how decades of work in biochemistry, genetics, and medicine led to the concept of precision nutrition. Dr. Zeisel explains how nutrients like choline, folate, methylfolate, betaine, and vitamin B12 interact with our genes. And he explains why common genetic variants can change how much of these nutrients our bodies actually need.

They also touch on why pregnancy, estrogen, fertility, and even sperm health are profoundly influenced by these metabolic pathways, and why traditional nutrition guidelines may miss the mark for many people.

Listeners will learn how emerging genetic tests can help identify individual "roadblocks" in metabolism. This episode is a powerful reminder that when it comes to nutrition, personalized science matters.
