#413 PKU Beyond the Diet: Food, Mental Health, and Daily Life
For most people, eating is an ordinary part of the day. But when you have phenylketonuria (PKU), every meal can involve calculations, preparation, medical monitoring, and decisions that affect how your brain and body feel.
This is DNA Today, a podcast from Gene Pool Media, where we explore the breakthroughs, challenges, and human impact of genetics and genomics. I’m your host Kira Dineen, a genetic counselor and award-winning science podcaster and speaker.
This is a continuation of our PKU series, sponsored by PTC Therapeutics. In the first episode (Episode 399), we explored how PKU helped launch newborn screening and why early diagnosis can completely change a child’s future.
In this second episode, we’re looking at what comes next: what it actually means to manage PKU through food, and how this affects school, friendships, celebrations, mental health, independence, and a person’s relationship with food.
Joining us are a mother and daughter who have experienced that journey together:
Dr. Jennifer Brown is a geneticist, science communicator, and author of When the Baby Is Not OK: Hopes & Genes, a wonderful memoir about genetics, motherhood, and raising children with PKU.
Lillian Isabella is a playwright, actor, advocate, and former National PKU Alliance board member who lives with PKU. She is also Dr. Brown’s daughter.
Our guests are participating in this podcast to share their experience and opinions only. They are not providing any medical advice. Always check with your healthcare provider for treatment and screening advice.
