Researchers in Singapore found eating fruits high in beta-cryptoxanthin protect lungs against cancer.
According to an August 20 post on RealAge.com, an online health and wellness resource, papayas, oranges, tangerines, and mangoes are high in beta-cryptoxanthin which "neutralize cell-damaging free radicals - possibly even some of the damaging free radicals generated by cigarette smoke."
Loading up on these fruits also help with skin, digestion and joint health.
And, you may want to avoid foods that can harm your lungs making it more difficult to breathe, including "refined grains, cured and red meats, desserts, and fatty foods."
