Summary

We’ve all heard the phrase “you are what you eat,” but what if it’s more accurate to say “you feel what you eat”? Behind every meal, snack, or sugar crash is an intricate, fascinating connection between your brain and your gut - one that science is only just beginning to fully understand. In today’s episode, we explore the gut-brain axis: the real, two-way communication system that links your digestive health to your mental well-being. From serotonin production in your intestines to the surprising impact of fermented foods, we break down how what you eat influences your mood, focus, anxiety levels, and emotional regulation - and how your emotions, in turn, influence what you reach for in the fridge.

We explore:
•       The gut-brain axis
•       Why gut microbes might be responsible for your mood swings
•       Foods that support mental health - and ones that can destabilize it
•       Cycle syncing, cravings, and emotional shifts
•       The psychology of emotional eating and comfort food
•       How food morality and rigid diets can harm your mental well-being
•       How to find balance in the food noise

Whether you’re curious about how to eat for a better mood, or want to feel more connected to your body, this episode is for you.
