To lower cortisol, an anti-inflammatory, blood-sugar-stabilizing diet can help. Recommended: whole foods rich in vegetables, fruits, whole grains, healthy fats (omega-3 from fish, flaxseeds), and lean protein. Avoid highly processed foods, sugar, caffeine, and alcohol, as they can raise cortisol. Regular meals and adequate magnesium (nuts, seeds, leafy greens) and vitamin C (citrus, bell peppers) support adrenal function. Evidence is mostly observational and not definitive; individual responses vary. A DNA test for stress-related genes (e.g., COMT, FKBP5) provides only weak clues and does not replace a blood test. Important: Chronic stress requires holistic measures (sleep, exercise, mindfulness) – diet is one component, not a cure-all.
