What do studies say about Cortisol Ernährung?

The relationship between cortisol and nutrition is a well-studied area, but the provided context does not contain specific studies on this topic. General scientific consensus indicates that diet can influence cortisol levels: high sugar intake, caffeine, and processed foods may elevate cortisol, while a Mediterranean diet rich in omega-3s, magnesium, and fiber may help regulate it. However, evidence is mixed; many studies are observational or have small effect sizes. Without direct references from the given knowledge base, the evidence level is 'unclear'. For personalized advice, consulting a healthcare professional is recommended, especially if cortisol-related symptoms (e.g., fatigue, weight gain) are present. Consumer DNA or lab tests claiming to predict cortisol response should be interpreted with caution, as they often lack clinical validation.
