  • Selenium: This essential mineral supports and protects lung tissue from free radicals. It is found in Brazil nuts, fish, and whole grains.
  • Folate: Folate boosts the production of red blood cells and maintains healthy lungs. Leafy greens, beans, and lentils are great sources of this essential vitamin.
  • Curcumin: Turmeric is a fantastic antioxidant with anti-inflammatory properties. You can find curcumin in turmeric.
  • Garlic: Garlic adds flavor to foods, and it also has incredible antimicrobial properties and can help fight off respiratory infections.
  • Ginger: Another way to cook with healthy ingredients is to add ginger. This spice has anti-inflammatory and immune-boosting properties that can support overall respiratory health.

When you are making a conscious effort to be healthy and boost lung health, there are other things to remember in addition to these specific nutrients.
