Gut Check

What genomics can tell us about food safety, the microbiome, and the mind.

You’ve heard the saying, “you are what you eat”... Well, our gut microbes take that very literally. If you’ve ever gone on vacation, eaten something tasty, and next thing you find yourself bonding with a bathroom floor, you’re not alone. Food poisoning might occasionally make for a good story later, but it’s a serious issue that lands millions of people in hospitals every year– and tracing the culprit isn’t always as simple as pointing at last night’s tacos.

In this episode, Dr. Kaylee Byers chats with microbiologist Dr. Lawrence Goodridge, who explains how genomics helps track foodborne outbreaks – from the harmful bacteria in our food to the microbes living inside us. Then, Dr. Mary Sco. dives into the science of the gut-brain connection, revealing how your gut and brain are constantly in conversation.

So grab a snack, and get ready to stomach the science.
