Risks and limits of Cortisol Ernährung

The concept of a 'cortisol diet' is not well-defined in scientific literature. Cortisol is a stress hormone regulated by the HPA axis; diet can influence it but effects are modest and variable. Some commercial tests claim to tailor nutrition to lower cortisol based on genetics or biomarkers, but evidence is weak. Observational studies suggest that high sugar intake, skipping meals, and chronic calorie restriction may elevate cortisol, while balanced meals with adequate protein, omega-3s, and magnesium may help normalize it. However, these effects are small and not clinically meaningful for most people. Risks include over-reliance on unvalidated tests, unnecessary dietary restrictions, and ignoring underlying medical conditions (e.g., Cushing's syndrome, adrenal insufficiency). Cortisol levels fluctuate diurnally and with stress; single measurements are unreliable. Without clinical symptoms, a 'cortisol diet' is not evidence-based. The context provided lacks direct studies on cortisol and nutrition; thus evidence grade is unclear. Consumers should be cautious of marketing claims and consult a doctor for persistent symptoms like fatigue, weight gain, or hypertension.
