What is cortisol?
Cortisol is your bodyâs primary stress hormone, produced by the adrenal glands.
It helps regulate:
- Energy and blood sugar
- Inflammation
- Blood pressure
- Sleepâwake cycles
- Your âfightâorâflightâ response
The problem isnât cortisol itself â itâs chronically elevated cortisol, which can contribute to:
- Belly fat
- High blood sugar
- High blood pressure
- Poor sleep
- Low mood or irritability
- Weakened immunity
Food canât replace medical care, but certain nutrients do help your body regulate cortisol more effectively.
