A diet rich in vegetables, whole grains, and healthy fats provides vitamins and antioxidants to enhance lung function.
Healthy fats
Omega-3 is a good fat that contributes to anti-inflammation, helps relieve symptoms and improve asthma, bringing many benefits to the lungs. This type of fatty acid also enhances cardiovascular activity, improves the immune system, enhances memory…
Lung-enriching foods rich in omega-3 in the menu should be given priority such as salmon, mackerel, nuts (walnuts, almonds, flaxseeds…), olive oil, and oysters. The recommended amount of omega-3 for people 19 years and older is 1.6 g for men and 1.1 g for women.
Protein
Protein helps keep respiratory muscles healthy, provides adequate protein for the body and is necessary for the treatment of respiratory diseases. This nutrient is also beneficial for damaged tissues, synthesizing substances that strengthen the immune system. Foods rich in protein include seafood, poultry, eggs, legumes, nuts, soybeans… People with anorexia can drink more milk to ensure their body has enough protein.
Pure carb foods
Carbohydrates (carbs) include starch, sugar and fiber, which are fuel for metabolic processes, energy generation, digestive and respiratory functions and many other important activities. The body’s lack of carbohydrates for a long time can lead to symptoms such as fatigue, lack of energy, cravings, and indigestion.
Choose pure, unprocessed carbs instead of refined carbs and simple sugars. Pure carbs are rich in fiber, which contributes to reducing blood sugar levels. Foods rich in healthy carbohydrates such as potatoes, oats, whole grains, and legumes provide fiber and antioxidants.
Fresh food
Vegetables and fruits contain lots of vitamins A, B, C, D, E… which are good for lung health. Vitamin C improves the body’s immunity against viral and bacterial infections such as pneumonia and other respiratory diseases. Supplementing vitamin D reduces the possibility of lung infections and improves asthma symptoms. Vitamin A contributes to preventing lung infections
Apples, grapefruit, oranges, beets… are fruits and vegetables that enhance lung function. Apples are rich in the phytonutrient quercetin, which reduces the risk of asthma and complications of chronic obstructive pulmonary disease. Quercetin in apples also acts as an anti-inflammatory.
Eating beets can relax blood vessels, increase oxygen flow and reduce blood pressure (especially in people with pulmonary hypertension). Beets also contain antioxidants and anti-inflammatory properties.
Foods rich in potassium
Potassium plays an important role in lung function. Potassium deficiency can cause respiratory problems. Besides, this nutrient also maintains fluid balance and keeps the brain, nerves, heart and muscles functioning normally. Food sources rich in potassium are bananas, avocados, milk, beans and salmon.
