Lung capacity is the maximum amount of oxygen your lungs can hold. As you age, lung capacity tends to decrease; having a chronic illness decreases lung capacity at a more rapid rate. The lower the capacity the more difficult it is to breathe. There are many factors that can increase lung capacity including medications, exercise and what you eat. Consuming healthy food can enhance your lung capacity.
The Lungs
The lungs are vital organs required for gas exchange. They provide the oxygen for the blood to bring to the rest of the body. The amount of oxygen your lungs can hold is your lung capacity; it is different for everyone. Lung capacity depends on your age, size, weight, illnesses and lifestyle. If you smoke or have been exposed to air pollutants, lung capacity is affected. As lung capacity decreases, breathing becomes more difficult. Eventually, if lung capacity keeps deteriorating, oxygen may be prescribed by your doctor.
Fruits and Vegetables
Fruits and vegetables with high amounts of vitamins C and E have shown to increase lung capacity. Both of these vitamins are strong antioxidants and protect the lungs from free radicals. Free radicals damage the tissues of the lungs and cause decrease of lung function. Many fruits and vegetables contain vitamins C and E. Citrus fruits, green leafy vegetables, and tomatoes are good sources of these vitamins.
High Fat Foods
High fat foods have a negative affect on lung function. These types of foods can cause lung inflammation and lead to obesity. Obesity has a direct impact on lung capacity and lung function. The more you weigh the more pressure there is on the lungs making it more difficult to breathe. Excess weight causes the lungs to lose their elasticity and will, over time, deteriorate lung capacity. Consuming foods that are lower in fat can aid in weight loss.
Fish
Smoking, pollutants and illnesses can all cause lung damage and lung capacity to decrease. Noel Peterson, from the Center of Traditional Medicine, reports those who consume high amounts of fish have less lung inflammation, lower incidences of bronchial constriction and reduced wheezing. Fish contains omega-3 fatty acids which can protect the lungs. Salmon, cod, tuna and halibut all contain high amounts of omega-3.
