Avocados are a source of key nutrients, including healthy fats and fiber. They also contain anti-inflammatory and antioxidant compounds and may help reduce heart disease risk.

Nutritious, versatile, and delicious, avocados have become a kitchen staple in many homes around the world.

While some people refer to avocados as fruits and some people say they’re a vegetable, avocados (Persea americana) are actually considered fruits, specifically berries. They’re a member of the Lauraceae plant family, which also includes the cinnamon tree.

Avocados are native to Mexico and Central America, but they are cultivated in many areas of the world, including North America.

In the United States, California is the top producer of avocados and is home to more than 5,000 avocado farms, which generate over 400 million pounds of avocados each year.

These fruits are an important part of traditional Mexican, Central American, and South American cuisine and are used in dishes like guacamole, salads, tacos, and more.

Avocados are extremely popular in the health and wellness world because they’re highly nutritious and have been linked to several health benefits.

This article lists 7 benefits of eating avocados, including more about nutrition, weight loss, and how to enjoy them.

1. Excellent source of nutrients

Avocados are high in a number of important nutrients, many of which are lacking in modern diets.

Here is the nutrition breakdownTrusted Source for a 7-ounce (201-gram) avocado:

• Calories: 322
• Fat: 30 grams
• Protein: 4 grams
• Carbs: 17 grams
• Fiber: 14 grams
• Vitamin C: 22% of the daily value (DV)Trusted Source
• Vitamin E: 28% of the DV
• Vitamin K: 35% of the DV
• Riboflavin (B2): 20% of the DV
• Niacin (B3): 22% of the DV
• Pantothenic acid (B5): 56% of the DV
• Pyridoxine (B6): 30% of the DV
• Folate: 41% of the DV
• Magnesium: 14% of the DV
• Potassium: 21% of the DV
• Copper: 42% of the DV
• Manganese: 12% of the DV

As you can see, avocados are exceptionally nutritious fruits and are a concentrated source of healthy fats and fiber, plus a number of vitamins and minerals.

They’re rich in nutrients that are often lacking in many people’s diets, including magnesium, B6, vitamin C, vitamin E, and folate.

For example, half of an avocado packs 10% of the DV for potassium.

Potassium is considered a “nutrient of public health concern” by the U.S. Department of Health and Human ServicesTrusted Source. This is because it’s a mineral that Americans commonly do not consume enough of.

In fact, a 2015 studyTrusted Source that included data on 4,730 U.S. adults found that fewer than 3% had potassium intakes greater than the set daily value (DV) for potassium of 4,700 mgTrusted Source per day.

Potassium is needed for several critical bodily functions, including blood pressure regulation and nervous system function. Getting the recommended amount of potassium on a daily basis may help protectTrusted Source against hypertension and stroke.

Avocados also provide nutrients that are essential for the health of the immune system, including vitamin C, B6, and E.

Half of an avocado provides 15% of your daily needs for B6, a nutrient that plays many key roles in the body including heart health, cancer prevention, and cognitive function.

Avocados contain an abundance of nutrients that are essential for optimal health, and regularly consuming avocados could help improve overall diet quality.

2. Beneficial for gut health

Avocados are high in fiber, providing about 14 gramsTrusted Source in each avocado. That’s nearly half of the current DV for this important nutrient.

Getting enough fiber in your diet is essential for the health of the digestive system because it helps promote the growth of healthy bacteria.

A study with 163 adultsTrusted Source considered overweight found that people who consumed 175 grams (men) or 140 grams (women) of avocado daily for 12 weeks had lower fecal bile acid concentrations and increased bacterial diversity compared to a control group.

Greater bile acid concentrations induce intestinal inflammation and are related to the growth of microbes associated with negative health outcomes like colon cancer.

Additionally, the avocado group had more of the bacteria Faecalibacterium, Lachnospira, and Alistipes, all of which produce short-chain fatty acids (SCFAs), including butyrate. SFCAs help fuel colon cells and protect against diseases like colorectal cancer and inflammatory bowel disease.

Even though these findings are promising, this study was partially funded by the Hass Avocado Board, which could have influenced study results.

Also, keep in mind that all fiber-containing foods, including fruits, vegetables, nuts, and seeds, are important for gut health. The most important factor in supporting digestive health is eating a variety of fiber-containing foods, not just avocados.

3. May help reduce heart disease risk factors

Regularly consuming nutrient-dense foods like avocados could help protect against heart disease.

The vitamins, minerals, healthy fats, and fiber found in avocados all play a role in keeping the cardiovascular system healthy.

Study findingsTrusted Source suggestTrusted Source that an avocado-rich diet may help improve heart disease risk factors, which may help prevent the onset of heart disease.

Many studies investigating the effects of avocados on heart health were funded by the Hass Avocado Board. Even though this doesn’t discredit study findings, some expertsTrusted Source suggest that industry involvement in peer-reviewed research could skew results.

Nonetheless, avocados may help increase heart-protective HDL cholesterol and decrease levels of oxidized LDL cholesterol, a type of cholesterol that’s significantly associated with atherosclerosis, or the buildup of plaque along artery walls.

Additionally, the high potassium and magnesium content of avocados is beneficial for blood pressure regulation. Keeping blood pressure at a healthy level is critical for heart disease prevention.

4. A rich source of antioxidant and anti-inflammatory compounds

In addition to vitamins, minerals, healthy fats, and fiber, avocados are packed with bioactive compounds including carotenoids, vitamin C, vitamin E, and phenolic compounds.

These substances have been shown to have significant antioxidant, neuroprotective, and cardioprotective activities.

For example, carotenoids found in avocados including lutein, α-Carotene, and β-Carotene have been shownTrusted Source to have strong antioxidant effects, protecting against oxidative damage, which is associated with the progression of many chronic diseases.

Because avocados are high in antioxidants, regularly eating avocados may help increase the body’s antioxidant defenses.

A small studyTrusted Source that included 45 people found that eating an avocado a day increased blood levels of the carotenoid lutein compared with a typical Western diet without avocado.

What’s more, having greater dietary intake and higher blood levels of antioxidants contained within avocados, like vitamin C and carotenoids, has been associated with better cognitive functionTrusted Source, improved heart healthTrusted Source, and more.

5. May help promote a healthy body weight

Although there are multiple factors that influence weight, following a nutritious and balanced diet is perhaps most important when it comes to reaching and maintaining a healthy body weight, which is critical for disease prevention.

Although avocados are high in calories, they’re packed with nutrients and help promote satiety, thanks to their high fiber and healthy fat content.

Research shows that following a dietary pattern rich in fibrous foods, like fruits and vegetables, may help support weight loss. Plus, people who eat more fiber tend to maintainTrusted Source healthier body weights compared to those who follow lower fiber diets.

In a studyTrusted Source that included 345 people, it was found that fiber intake was the most influential predictor of body weight, independent of calorie and macronutrient intake.

Plus, a number of studies have associated avocado intake with decreased weight gainTrusted Source, improved satietyTrusted Source, and decreased abdominal fatTrusted Source.

However, nearly all studies investigating the effects of avocado consumption on weight loss are funded by the Hass Avocado Board. Again, although this doesn’t discredit study results, food industry funding may influence study outcomes.

Regardless, it’s clear that increasing foods rich in dietary fiber likely promotes weight loss by promoting satiety. So, eating more high-fiber foods, like avocados, may be a good choice for those wishing to promote weight management or maintain body weight.

6. A smart choice during pregnancy and breastfeeding

During pregnancy and breastfeeding, nutrient demands significantly increase.

For example, during pregnancy:

• Folate requirements increase from 400 μg to 600 μgTrusted Source.
• Potassium needs jump from 2,600 mg to 2,900 mgTrusted Source.
• Vitamin C needs increase from 75 to 85 mgTrusted Source.

Folate needs increase significantly during pregnancy. Unfortunately, many pregnant people around the world fall short of the recommended folate intake, which may increase the risk of pregnancy complications.

One avocado delivers 27%Trusted Source of the recommended folate intake during pregnancy.

Eating avocados can also help you reach the recommended intake levels for nutrients that are needed in greater amounts during pregnancy and breastfeeding, like vitamin C, potassium, and B6.

Additionally, the high fiber content of avocados may help prevent constipation, which is extremely common during pregnancy.

For a satisfying pregnancy- and breastfeeding-friendly meal or snack idea, try topping whole grain toast (carbs) with 1/2 an avocado (fat) and over-easy egg or scoop of cottage cheese (for protein).

7. Versatile and delicious ingredient

In addition to being highly nutritious, avocados can be used in a number of recipes, both sweet and savory. This makes them a smart ingredient to have on hand.

Here are some ideas for how to incorporate more avocado into your diet:

• Use avocado in place of mayo with Greek yogurt in chicken, salmon, egg, and tuna salads.
• Make a classic guacamole using ingredients like avocados, onions, lime, and cilantro.
• Top chicken breasts with a salad of tomato and cubed avocado.
• Toss frozen avocado chunks into smoothies for a source of healthy fat.
• Top chilis and soups with sliced avocado.
• Incorporate avocado into salads and grain bowls.
• Whip up a dairy-free avocado chocolate mousse.
• Bread avocados and bake them for a crispy treat.
• Pair half an avocado with eggs and berries for a filling breakfast.
• Smash avocado on top of toast or a half roasted sweet potato.
• Stuff avocados with chicken salad or bean salad.
• Use avocados in tacos and burritos.
• Blend avocado with olive oil, lemon juice, and seasonings for a quick and easy creamy dressing.
• Top your favorite burger with sliced avocado.
• Sprinkle an avocado half with a bit of coarse salt and pepper and enjoy it right out of the rind.

There are so many ways to use avocados, so don’t be afraid to experiment.

If you’re looking for a way to keep your avocados as fresh as possible, place ripe avocados in the refrigerator until you’re ready to enjoy them.

If your avocado is still hard and green, let it sit on your counter for several days to ripen.

Ripe avocados are slightly soft to the touch and usually have a deep green color. If your avocado is very mushy and dents when poked, it’s likely past its prime.

However, even overripe avocados can be incorporated into recipes like baked goods and dressings, so don’t toss them unless they have a sour taste or smell, are moldy, or if the flash is extremely discolored.

The bottom line

Avocados contain an impressive amount of nutrients and are especially rich in fiber, B6, vitamin C, potassium, vitamin E, folate, and copper.

Eating avocados regularly may benefit health in several ways, including protecting against heart disease, improving overall diet quality, improving satiety, and promoting gut health.

Plus, they’re versatile and delicious.

The 20 Best Foods for Lung Health

The 20 Best Foods for Lung Health

By Jillian Kubala

Posted on June 8, 2025

-

Keeping your lungs healthy is essential to feeling your best. Yet, common factors, including exposure to cigarette smoke and environmental toxins, as well as eating an inflammatory diet, can take a toll on this pair of important organs.

What’s more, common conditions, such as asthma, chronic obstructive pulmonary disease (COPD), and pulmonary fibrosis, can significantly affect your quality of life (1Trusted Source, 2Trusted Source).

However, research has shown that lifestyle modifications, including following a nutrient-rich diet, can help protect your lungs and even reduce lung damage and symptoms of disease.

What’s more, specific nutrients and foods have been identified to be particularly beneficial for lung function.

Here are 20 foods that may help boost lung function.

1. Beets and beet greens

The vibrantly colored root and greens of the beetroot plant contain compounds that optimize lung function.

Beetroot and beet greens are rich in nitrates, which have been shown to benefit lung function. Nitrates help relax blood vessels, reduce blood pressure, and optimize oxygen uptake (3Trusted Source).

Beetroot supplements have been shown to improve physical performance and lung function in people with lung conditions, including COPD and pulmonary hypertension, a disease that causes high blood pressure in the lungs (4Trusted Source, 5Trusted Source).

Additionally, beet greens are packed with magnesium, potassium, vitamin C, and carotenoid antioxidants — all of which are essential to lung health (6Trusted Source).

2. Peppers

Peppers are amongst the richest sources of vitamin C, a water-soluble nutrient that acts as a powerful antioxidant in your body. Getting enough vitamin C is especially important for those who smoke.

In fact, due to the damaging effects of cigarette smoke on your body’s antioxidant stores, it’s recommended that people who smoke consume an extra 35 mg of vitamin C per day (7Trusted Source).

However, many studies show that smokers may benefit from higher doses of vitamin C and that smokers with high vitamin C intake have better lung function than those with lower vitamin C intake (8Trusted Source).

Consuming just one medium-sized (119-gram) sweet red pepper delivers 169% of the recommended intake for vitamin C (9Trusted Source).

3. Apples

Research has shown that regularly eating apples may help promote lung function.

For example, studies show that apple intake is associated with a slower decline in lung function in ex-smokers. Additionally, consuming five or more apples per week is associated with greater lung function and a reduced risk of developing COPD (10Trusted Source, 11Trusted Source).

Apple intake has also been linked to a lower risk of asthma and lung cancer. This may be due to the high concentration of antioxidants in apples, including flavonoids and vitamin C (12Trusted Source.

4. Pumpkin

The brightly colored flesh of pumpkins contains a variety of lung-health-promoting plant compounds. They’re especially rich in carotenoids, including beta carotene, lutein, and zeaxanthin — all of which have powerful antioxidant and anti-inflammatory properties (13Trusted Source).

Studies show that having higher blood levels of carotenoids is associated with better lung function in both older and younger populations (14Trusted Source, 15Trusted Source).

People who smoke may significantly benefit from consuming more carotenoid-rich foods like pumpkin.

Evidence suggests that smokers may have 25% lower concentrations of carotenoid antioxidants than nonsmokers, which can harm lung health (16Trusted Source).

5. Turmeric

Turmeric is often used to promote overall health due to its potent antioxidant and anti-inflammatory effects. Curcumin, the main active component in turmeric, may be especially beneficial for supporting lung function (10Trusted Source).

A study in 2,478 people found that curcumin intake was associated with improved lung function. Plus, the lung function of smokers who had the highest intake of curcumin was significantly greater than smokers who had low curcumin intake (17Trusted Source).

In fact, high curcumin intake in smokers was associated with 9.2% greater lung function, compared with smokers who did not consume curcumin (17Trusted Source).

6. Tomato and tomato products

Tomatoes and tomato products are among the richest dietary sources of lycopene, a carotenoid antioxidant that has been associated with improved lung health.

Consuming tomato products has been shown to reduce airway inflammation in people with asthma and improve lung function in people with COPD (11Trusted Source).

A 2019 study in 105 people with asthma demonstrated that a diet rich in tomatoes was associated with a lower prevalence of poorly controlled asthma. Plus, tomato intake is also associated with a slower decline in lung function in ex-smokers (11Trusted Source, 18Trusted Source, 19Trusted Source).

7. Blueberries

Blueberries are loaded with nutrients, and their consumption has been associated with a number of health benefits, including protecting and preserving lung function (20).

Blueberries are a rich source of anthocyanins, including malvidin, cyanidin, peonidin, delphinidin, and petunidin (20).

Anthocyanins are powerful pigments that have been shown to protect lung tissue from oxidative damage (21Trusted Source, 22Trusted Source).

A study in 839 veterans found that blueberry intake was associated with the slowest rate of decline in lung function and that consuming 2 or more servings of blueberries per week slowed lung function decline by up to 38%, compared with low or no blueberry intake (23Trusted Source).

8. Green tea

Green tea is a beverage that has impressive effects on health. Epigallocatechin gallate (EGCG) is a catechin concentrated in green tea. It boasts antioxidant and anti-inflammatory properties and has been shown to inhibit fibrosis or scarring of tissues (24Trusted Source).

Pulmonary fibrosis is a disease characterized by progressive, lung-function-compromising scarring of lung tissue. Some research shows that EGCG may help treat this disease.

A small 2020 study in 20 people with pulmonary fibrosis found that treatment with EGCG extract for 2 weeks reduced markers of fibrosis, compared with a control group (25Trusted Source).

9. Red cabbage

Red cabbage is an affordable and rich source of anthocyanins. These plant pigments give red cabbage its vivid color. Anthocyanin intake has been linked to a reduced decline in lung function (23Trusted Source).

What’s more, cabbage is packed with fiber. Studies show that people who consume more fiber have better lung function than those who consume low amounts of fiber (26Trusted Source).

10. Edamame

Edamame beans contain compounds called isoflavones. Diets rich in isoflavones have been associated with a reduced risk of numerous diseases, including COPD (27Trusted Source).

A study in 618 Japanese adults found that people with COPD had much lower intakes of dietary isoflavones, compared with healthy control groups. What’s more, isoflavone intake was significantly associated with better lung function and reduced shortness of breath (28Trusted Source).

11. Olive oil

Consuming olive oil may help protect against respiratory conditions like asthma. Olive oil is a concentrated source of anti-inflammatory antioxidants, including polyphenols and vitamin E, which are responsible for its powerful health benefits.

For example, a study that included 871 people found that those who had high olive oil intake had a reduced risk of asthma (29Trusted Source).

What’s more, the Mediterranean diet, which is rich in olive oil, has been shown to benefit lung function in smokers, as well as people with COPD and asthma (30Trusted Source, 31Trusted Source, 32Trusted Source).

12. Oysters

Oysters are loaded with nutrients that are essential to lung health, including zinc, selenium, B vitamins, and copper (33Trusted Source).

Studies show that people with higher blood levels of selenium and copper have greater lung function, compared with those with lower levels of these nutrients (10Trusted Source.)

Additionally, oysters are an excellent source of B vitamins and zinc, nutrients that are especially important for people who smoke.

Smoking depletes certain B vitamins, including vitamin B12, which is concentrated in oysters. What’s more, studies show that higher zinc intake may help protect smokers from developing COPD (34Trusted Source, 35Trusted Source).

13. Yogurt

Yogurt is rich in calcium, potassium, phosphorus, and selenium. According to research, these nutrients may help boost lung function and protect against COPD risk (36Trusted Source).

A study in Japanese adults found that higher intakes of calcium, phosphorus, potassium, and selenium were associated with increased lung function markers, and those with the highest calcium intake had a 35% reduced risk of COPD (37Trusted Source).

14. Brazil nuts

Brazil nuts are amongst the richest sources of selenium that you can eat. A single Brazil nut may contain over 150% of the recommended intake for this important nutrient, though concentrations vary significantly depending on growing conditions (38Trusted Source, 39Trusted Source, 40Trusted Source).

Studies show that a high selenium intake may help protect against lung cancer, improve respiratory function in people with asthma, and enhance antioxidant defenses and immune function, which may help improve lung health (41Trusted Source, 42Trusted Source, 43Trusted Source).

Because Brazil nuts are such a concentrated source of selenium, it’s recommended to keep your intake to just one or two nuts per day.

15. Coffee

In addition to boosting your energy levels, your morning cup of joe may help protect your lungs. Coffee is packed with caffeine and antioxidants, which may be beneficial for lung health.

Research shows that coffee intake may help improve lung function and protect against respiratory diseases. For example, caffeine acts as a vasodilator, meaning it helps open blood vessels, and it may help reduce symptoms in people with asthma, at least in the short term (44).

Additionally, a review of 15 studies found that long-term coffee intake was associated with positive effects on lung function and a reduced risk of asthma (45Trusted Source).

16. Swiss chard

Swiss chard is a dark leafy green that’s high in magnesium. Magnesium helps protect against inflammation, and it helps bronchioles — tiny airways inside your lungs — stay relaxed, preventing airway restriction (46Trusted Source).

Higher magnesium intake has been associated with better lung function in a number of studies. What’s more, low magnesium levels are associated with worsening symptoms in people with COPD (10Trusted Source, 47Trusted Source, 48Trusted Source).

Additionally, many studies have linked greater intake of leafy green vegetables like Swiss chard to a reduced risk of lung cancer and COPD (10Trusted Source, 49Trusted Source).

17. Barley

Barley is a nutritious whole grain that’s high in fiber. High fiber diets rich in whole grains have been shown to have a protective effect on lung function and may reduce the risk of mortality from lung-related diseases (10Trusted Source, 50Trusted Source).

The antioxidants found in whole grains like flavonoids and vitamin E also promote lung health and protect against cellular damage (10Trusted Source).

18. Anchovies

Anchovies are tiny fish that are packed with anti-inflammatory omega-3 fats, as well as other lung-health-promoting nutrients like selenium, calcium, and iron (48Trusted Source).

Eating omega-3-rich fish like anchovies may be particularly beneficial for people with inflammatory lung diseases like COPD. A 2020 study found that a higher intake of omega-3 fats was associated with reduced COPD symptoms and improved lung function (51Trusted Source).

What’s more, consuming an omega-3-rich diet may help reduce symptoms in people with asthma (52Trusted Source).

19. Lentils

Lentils are high in many nutrients that help support lung function, including magnesium, iron, copper, and potassium (53Trusted Source).

The Mediterranean diet, which has been associated with promoting lung health, is high in legumes like lentils.

Research has shown that following a Mediterranean dietary pattern can preserve lung function in people who smoke. Plus, eating fiber-rich lentils may help protect against lung cancer and COPD (54Trusted Source, 55Trusted Source).

20. Cocoa

Cocoa and cacao products like dark chocolate are high in flavonoid antioxidants and contain a compound called theobromine, which helps relax the airways in the lungs (56Trusted Source).

Cocoa intake has been associated with a lower risk of allergic respiratory symptoms and may help protect against lung cancer (57Trusted Source, 58Trusted Source).

Additionally, a study that included 55,000 people found that those with higher flavonoid consumption from foods, including chocolate products, had better lung function than people who had diets low in flavonoids (59Trusted Source).

The bottom line

Consuming a diet high in nutritious foods and beverages is a smart way to support and protect lung health.

Coffee, dark leafy greens, fatty fish, peppers, tomatoes, olive oil, oysters, blueberries, and pumpkin are just some examples of foods and drinks that have been shown to benefit lung function.

Try incorporating a few of the foods and beverages listed above into your diet to help support the health of your lungs.
