Food has the power to energize, balance, and center us. And when it comes to mental health, what’s on your plate plays a bigger role than you might think.

Our bodies can’t produce serotonin (a neurotransmitter that regulates mood) without nutrients such as iron and tryptophan, found in oats, milk, and bananas.

A balanced gut microbiome supports the production of serotonin (approximately 90% of serotonin is made in the gastrointestinal tract), but imbalances can lead to inflammation and mood disorders such as depression and anxiety. Supporting your gut through brain-healthy whole foods and probiotics will also support your mind.
