How Your Lungs Work & Why Diet Matters
Anatomy & Function: Lungs consist of a complex network of airways (bronchi, bronchioles) ending in microscopic sacs (alveoli) where gas exchange occurs. Their primary tasks: deliver oxygen and remove carbon dioxide. They’re also a first line of defense against pathogens and pollutants, thanks to cilia, mucus, and immune cells.
Common Stressors: Air pollution (PM2.5, ozone), cigarette smoke, allergens and infections all challenge lung integrity. Over time, chronic inflammation and oxidative stress can damage airway lining, reduce elasticity, or impair immune response, contributing to bronchitis, asthma, COPD, and even reduced exercise capacity.
Role of Nutrition
Antioxidants neutralize free radicals created by pollutants and inflammation.
Omega‑3 fats reduce inflammatory signaling and may widen airways.
Vitamins/minerals such as vitamin C, E, A, D, magnesium and selenium support immune defense and repair.
Phytonutrients found in fruits, vegetables and spices modulate inflammation and protect tissue integrity.
Together, diet and lifestyle play complementary roles in promoting lung resilience, reducing symptom burden, and improving breathing.
