Your brain is always “on.”
It takes care of your thoughts and movements, your breathing and heartbeat, your senses — it works hard 24/7, even while you’re asleep. This means your brain requires a constant supply of fuel. That “fuel” comes from the foods you eat — and what’s in that fuel makes all the difference. Put simply, what you eat directly affects the structure and function of your brain and, ultimately, your mood.
Serotonin is a neurotransmitter that helps regulate sleep and appetite, mediate moods, and inhibit pain. 95% of your serotonin is produced in your gastrointestinal tract. So, what we eat matters and can impact how we feel.
