“text”: “Perhaps the best-known neurotransmitter thanks to its powerful effect on mood, serotonin plays a role in digestion, bone health, libido, and pain regulation. It also soothes negative emotions, boosts stress resilience, and helps regulate circadian rhythms.
If you feel anxious or overwhelmed, or struggle to sleep, your serotonin levels may be running low.

Eating carbs helps tryptophan find its way into the production line for your brain to make serotonin, while the fiber in complex carbs helps regulate your blood sugar.”
