12 Calming Foods for the Vagus Nerve Diet That Reset Your Stress Response

5. Avocados

Avocados are a nourishing source of monounsaturated fats, potassium, magnesium, and B vitamins that support steady energy and nervous system function. Healthy fats help with absorption of fat‑soluble nutrients like vitamin D, which plays into overall wellbeing and mood balance. Adding avocado to a breakfast or lunch — on toast, in salads, or blended into smoothies — helps prevent blood sugar dips that can amplify stress reactivity. Their creamy texture and versatility make them an easy, everyday addition to meals that support relaxation and recovery.

6. Bananas

Bananas are a quick, portable source of carbohydrates, potassium, vitamin B6, and precursors to neurotransmitters like serotonin. When stress makes you reach for a quick bite, a banana pairs gentle glucose with nutrients that help steady mood and support the nervous system. They’re especially useful before or after activity to replenish electrolytes and help the body shift back toward rest. If you combine a banana with a bit of protein like nut butter, the balanced snack will support longer-lasting calm.
