Best Foods for Lung Health
Keeping your lungs healthy is essential to feeling your best. Exposure to air pollution, cigarette smoke, and an inflammatory diet can burden the lungs.
Research shows that nutrient‑rich diets may help support lung health and reduce the rate of lung decline. Specific foods are emerging as particularly beneficial [27,35].
Here are 20 foods that support lung health and what research says about them.
Apples
Apples are rich in antioxidants such as flavonoids and vitamin C, which can protect lung cells from oxidative damage caused by aging and smoking, while also reducing airway inflammation to help maintain long-term lung function (Hyson, 2011).
Research also indicates that people who consume five or more apples per week experience a slower decline in lung function, including former smokers [6,7].
Swiss Chard
Swiss chard is a rich source of magnesium, a mineral essential for many bodily functions, including muscle relaxation and respiratory support.
Some studies suggest that magnesium may play a role in regulating the airways and supporting lung function, particularly in conditions associated with airway inflammation (Al Alawi, 2018).
In addition, diets high in leafy greens, including Swiss chard, have been observed to be associated with better lung function in certain epidemiological studies [24,25,26].
Cocoa
Cocoa is a rich source of polyphenols, particularly the flavan-3-ols group (epicatechin, catechin, procyanidins).
A study suggested that cocoa intake may be associated with supportive effects in regulating respiratory allergic responses, which are considered aggravating factors in conditions such as asthma or allergic rhinitis (Rodríguez-Lagunas et al., 2019).
In addition, flavonoids—among which cocoa is a notable source of flavan-3-ols—have been investigated for their antioxidant and anti-inflammatory properties, with evidence indicating potential associations with lung health support [33].
Furthermore, some studies suggest that a higher intake of flavonoids—especially pro-anthocyanidins found in cocoa—may be associated with better lung health. This includes a lower risk of airway restriction and improved FEV1/FVC ratios, which are indicators of more efficient breathing and pulmonary function [34].
Edamame
Edamame, or young soybeans, has gained worldwide popularity for its pleasant taste and impressive nutritional profile.
It is packed with high-quality protein, dietary fiber, essential amino acids, polyunsaturated fatty acids, vitamins C and E, thiamin, minerals, and beneficial phytochemicals [11,15,16].
This rich composition supports overall wellness, including cardiovascular, bone, and immune health.
Another key factor driving consumer preference is edamame’s natural sweetness, largely derived from sucrose and alanine.
With its balance of taste and nutrition, edamame is increasingly recognized as both a healthful food and an appealing addition to modern diets.
Blueberries
Blueberries are rich in anthocyanins and polyphenols, compounds with strong antioxidant and anti-inflammatory properties that support lung health. These bioactives help reduce oxidative stress, calm airway inflammation, and protect lung tissue from environmental damage.
Research suggests that regular blueberry consumption may be linked to a slower decline in lung function, particularly as people age or when exposed to stressors like pollution or smoking [5,10].
Adding blueberries to the diet is a simple way to support respiratory function and long-term lung resilience.
Anchovies
Anchovies and other fatty fish are excellent sources of omega-3 fatty acids (EPA, DHA, DPA), which play an important role in supporting lung health [28,29].
These fatty acids generate resolvins, protectins, and maresins—bioactive compounds that help resolve inflammation and protect airway function.
By reducing oxidative stress and calming chronic inflammation, omega-3s contribute to better long-term respiratory resilience.
In former smokers, higher omega-3 intake has been associated with fewer respiratory symptoms and improved health-related quality of life.
Anchovies, along with fish oil and other seafood, are valuable dietary sources of omega-3s that help maintain healthy lungs and overall well-being.
Pumpkin
Pumpkins are packed with carotenoids like beta-carotene, lutein, and zeaxanthin, which act as antioxidants to help reduce oxidative stress and inflammation in lung tissues. These compounds support overall respiratory function by protecting cells and maintaining healthy airways [40].
In addition, pumpkin provides vitamins A, C, and E, along with minerals such as magnesium, zinc, selenium, and potassium. These nutrients contribute to immune defense, reduce oxidative damage, and help maintain normal cardiovascular function, which is important for efficient oxygen delivery [41].
Adding pumpkin to a balanced diet offers a nutrient-rich way to promote lung health and support long-term breathing resilience [1].
Red Cabbage
Red cabbage provides anthocyanins and fiber. Diets rich in whole plant fiber are consistently linked with better lung performance [13].
Olive Oil
Olive oil is a rich source of polyphenols and vitamin E, compounds that have been studied for their anti-inflammatory properties and potential contributions to overall well-being.
The Mediterranean diet—where olive oil plays a central role—has often been linked with favorable respiratory indicators, such as better maintenance of lung volume and airflow capacity [17].
In addition, epidemiological data from Europe suggest that higher intakes of oleic acid and olive oil are associated with positive respiratory outcomes, reinforcing the potential role of this oil as part of a balanced and health-supportive dietary pattern [18].
Lentils
Legumes, including lentils, are rich in dietary fibre and have been associated with reduced systemic inflammation. Diets high in legumes, such as the Mediterranean dietary pattern, have been linked to better lung function and a lower risk of respiratory decline [30,31].
Turmeric
Curcumin, the main bioactive compound in turmeric, may play a supportive role in lung health. Evidence from a large cohort of older adults in Asia found that higher intake of turmeric-rich curry was linked to better lung function values (FEV1 and FEV1/FVC).
The association appeared strongest among individuals with smoking exposure, suggesting that curcumin’s antioxidant and anti-inflammatory properties could help maintain healthier respiratory performance [9].
Coffee
Coffee is a natural source of caffeine and antioxidants, both of which have been studied for their potential impact on lung performance.
Evidence from controlled trials shows that caffeine may temporarily support airway openness and improve breathing efficiency for up to four hours, reflecting modest gains in lung capacity metrics (Welsh et al., 2010).
Observational reviews of long-term coffee consumption also suggest links with slightly better respiratory parameters, reduced risk factors, and overall healthier function among regular drinkers [23].
In addition, coffee contains bioactive compounds with antioxidant activity, which may help protect cells against oxidative stress and support pulmonary wellness.
Green Tea
Green tea is rich in antioxidants, especially epigallocatechin gallate (EGCG), a catechin known for its anti-inflammatory and antioxidant properties (Zhang et al., 2022).
These compounds help reduce oxidative stress, protect cells from free radical damage, and may support healthier airways.
By modulating inflammation and cellular stress, green tea can contribute to overall lung health and function [36].
Regular consumption provides a natural source of protective plant compounds that may help maintain respiratory resilience over time.
Tomatoes and Tomato Products
Tomatoes and tomato products are a valuable source of lycopene, vitamin C, β-carotene, and polyphenols, all of which provide strong antioxidant and anti-inflammatory support for lung health [6,8].
These compounds help reduce oxidative stress, protect lung tissue, and support clearer airways. Research shows that higher tomato intake may be linked with a slower decline in lung function over time, particularly in individuals with a history of smoking.
Tomato extracts and juices have also been observed to help lower airway inflammation, contributing to smoother breathing. Including tomatoes regularly in the diet can therefore promote respiratory resilience and overall lung wellness.
Peppers
Peppers—especially sweet red—are among the richest sources of vitamin C. Evidence from large cohort studies shows that higher intake of antioxidant-rich fruits such as apples and tomatoes is associated with a slower decline in lung function, particularly among ex-smokers [6,7].
Given that vitamin C intake has been highlighted as a beneficial factor in these studies, peppers—thanks to their exceptionally high vitamin C content—may also support lung health as part of a fruit- and vegetable-rich diet.
Yogurt
Yogurt is not only good for digestion but also beneficial for the lungs. It contains key minerals such as calcium, phosphorus, potassium, and selenium. Research shows that these nutrients help the lungs function more effectively and may reduce the risk of respiratory decline over time (Egeria Scoditti et al., 2019). Enjoying yogurt daily can therefore be a simple yet valuable habit to help keep your lungs healthy.
Brazil Nuts
Brazil nuts are an excellent natural source of selenium. Research indicates that maintaining higher selenium levels may help strengthen the body’s antioxidant defenses and is associated with markers of better lung health [19,20,21].
Oysters
Oysters are a nutrient-dense food that provides important minerals like zinc, selenium, copper, and B vitamins [37].
These nutrients play key roles in supporting antioxidant defenses and reducing cellular stress, which helps protect lung tissues from oxidative damage. Zinc and selenium are essential for immune balance and maintaining the integrity of airway cells [6].
Because smoking and environmental stressors can deplete these minerals, replenishing them through foods like oysters may help the body maintain stronger defense systems.
Including oysters as part of a balanced diet can support respiratory health and contribute to overall cellular resilience.
Barley
Barley is a nutritious whole grain that offers fiber, vitamins, minerals, and antioxidants. Its high fiber content supports gut health, which in turn may influence systemic inflammation and immune balance—factors important for maintaining healthy lungs [27].
The antioxidants in barley, including phenolic compounds and vitamin E, help protect airway cells from oxidative stress and may reduce irritation in the respiratory system.
Diets rich in whole grains like barley are also linked with better circulation and overall metabolic health, which indirectly benefits lung function. Adding barley to meals can be a simple way to support long-term respiratory resilience [27,38].
Beets and Beet Greens
Beets and beet greens are valuable foods that support overall lung and respiratory health.
Beets are naturally rich in nitrates, which the body can convert into nitric oxide—a compound that helps relax blood vessels, improve circulation, and support oxygen delivery throughout the body [39].
This process may aid breathing efficiency and help maintain healthy airflow. Beet greens, on the other hand, provide carotenoids, magnesium, and potassium, which contribute antioxidant and anti-inflammatory benefits while supporting normal muscle and airway function [3,4].
Including both beets and beet greens in the diet offers a nutrient-rich way to promote better oxygen use and lung wellness.
Conclusion
Including a variety of foods that support lung health, such as fruits, vegetables, legumes, whole grains, and healthy fats, may help protect breathing capacity and slow age-related decline.
While no single item is a remedy, choosing the best foods for lung health, like apples, tomatoes, or green tea, provides valuable antioxidants and nutrients.
Overall, focusing on foods good for lung health is a practical way to support long-term respiratory wellness.
