The basic function of the lungs is to transport oxygen from the air we breathe into the cells of the body and to remove dangerous carbon dioxide.
According to the US National Institutes of Health, the process of inhaling and exhaling is repeated about 25,000 times a day.
Several diseases of the lungs are linked to oxidative stress and harmful substances such as cigarette smoke, air pollutants and infections.
Nutritional factors and specific nutrients that protect against the oxidation process and prevent inflammation are involved in the genesis and progression of these diseases.
Lung diseases such as asthma, cancer, chronic obstructive pulmonary disease and pneumonia adversely affect the body's inherent ability to provide the necessary oxygen to its billions of cells.
As with most organs in the human body, the lungs are directly affected by the foods we choose to eat.
Here are five of the most important foods you should eat to ensure your lung health.
Pumpkin & sweet potatoes (beta-carotene): Research has shown that a diet rich in beta-carotene can benefit lung health. Beta-carotene is converted into vitamin A, an important nutrient for lung health. Other fruits and vegetables that benefit the lungs are apricots, broccoli, carrots, melon, mango and red peppers.
Green leafy vegetables (folic acid): Folic acid can prevent various forms of COPD, including asthma, chronic bronchitis and emphysema. A related study showed that COPD sufferers received significantly lower amounts of folic acid compared to healthy individuals.
Oranges (vitamin C): Foods high in vitamin C, including oranges, are associated with better lung function. People who follow a diet rich in vitamin C have a lower risk of developing lung cancer. This is especially true for those who eat a lot of citrus fruits. Other foods that fall into this category include broccoli, Brussels sprouts, green and red peppers, kiwis, potatoes and tomatoes.
Pulses: To optimise oxygen transport, healthy levels of haemoglobin, the protein molecules found in red blood cells that carry oxygen from the lungs to the tissues, are essential. In addition, hemoglobin stimulates internal processes that return carbon dioxide to the lungs to be eliminated from the body. Lentils and beans (red, black, etc.) increase hemoglobin levels. Combine them with foods rich in vitamin C to maximize iron absorption.
Dark chocolate (antioxidants): Dark chocolate is an excellent source of antioxidants, which are essential for counteracting the damage caused by oxidation of the body's cells. Oxidation has been shown to play a catalytic role in the development of many lung diseases. Good sources of antioxidants are also blueberries, cranberries, blueberries, blueberries, plums, strawberries, artichokes and red beans.
