Cortisol-Diet Relationship

Definition

Influence of diet on cortisol secretion and regulation, the primary stress hormone. Certain foods increase cortisol, while others help to decrease it.

How it works

Cortisol, secreted by the adrenal glands, follows a natural circadian rhythm with peaks in the morning and troughs in the evening. However, certain foods and eating patterns can disrupt this rhythm or amplify the inappropriate secretion of cortisol. Balanced meals with protein, fiber, and healthy fats help to stabilize cortisol, while meals rich in simple sugars or caffeine can destabilize it. The quality of sleep, directly linked to evening eating, also affects the regulation of cortisol the next day.

Role

Allows for the natural regulation of cortisol production through daily food choices.

Examples

• Protein-rich breakfast reducing morning cortisol • Caffeine increasing cortisol in sensitive individuals • Large dinner disrupting nighttime cortisol • Anti-inflammatory foods reducing stress response

Recommendations

Respect your circadian dietary rhythm: nutritious breakfast, balanced lunch, light dinner. Limit caffeine after 14:00 and prefer anti-inflammatory foods (fatty fish, berries, leafy greens). Wait 2-3 hours after eating before going to bed.

Key takeaway

A strategically planned diet according to your circadian rhythm can maintain balanced cortisol and protect your health.
