20 Nutritious Foods for Better Lung Health

Good lung health is crucial for overall well-being. Environmental toxins, poor lifestyle habits, and inflammatory foods can damage the lungs and lead to chronic obstructive pulmonary disease (COPD), asthma, pulmonary fibrosis, and other conditions that can significantly impact one’s quality of life. Adding nutritious foods to the meals can help mitigate some of this damage and reduce the symptoms and severity of lung disease. Try these 20 foods to boost lung function and improve breathing.

Apples
Research suggests that those who eat at least five apples a week are less likely to develop COPD. Apples contain an antioxidant called quercetin, which slows lung function decline. The fruit also helps lower the risk of asthma and lung cancer owing to its flavonoids and vitamin C content.

Beetroots
Beetroots and beet greens are rich sources of nitrates, which can help optimize lung function, relax blood vessels, and reduce blood pressure. Beets are also packed with beneficial nutrients, such as magnesium, potassium, vitamin C, and carotenoid antioxidants. Beetroot (in its natural form or as a supplement) is known to improve physical performance and lung function in those with COPD and pulmonary hypertension.

Peppers
Peppers are rich in vitamin C, a vitamin that has been shown to improve lung function. Vitamin C is a potent antioxidant that helps fight off free radicals in the body, thus improving its overall functioning. Spicy peepers also help thin the mucus, relieving chronic bronchitis flare-ups.

Pumpkins
Pumpkins contain carotene compounds with anti-inflammatory properties and antioxidant properties, such as beta-carotene, lutein, and zeaxanthin. These antioxidants improve lung function in people of all ages.

Turmeric
Turmeric is a popular ingredient used in many Southeast Asian dishes. Its antioxidant and anti-inflammatory properties are generally attributed to its main active ingredient, curcumin. Turmeric is particularly helpful for those with chronic inflammation, as it reduces the impact of free radicals and environmental toxins on the body’s vital organs.

Tomatoes
Tomatoes are a great source of a carotenoid antioxidant called lycopene. Lycopene has been proven to help reduce inflammation among people with asthma and improve lung function for those with COPD.

Blueberries
Blueberries are loaded with fiber and a general category of antioxidants called anthocyanins. Examples include malvidin, cyanidin, peonidin, delphinidin, and petunidin. These antioxidants can help protect the lung tissue from oxidative damage caused by free radicals. Research also suggests that people who eat foods high in fiber are less likely to develop respiratory conditions.

Red cabbage
Red cabbage is also an affordable and rich source of anthocyanins and fiber, which can help protect lung function and promote better breathing.

Green tea
Green tea contains a catechin called epigallocatechin gallate (EGCG). It has antioxidant and anti-inflammatory properties and has been shown to reduce the scarring of tissues. Drinking hot green tea at least twice a day can help reduce the risk of COPD and improve symptoms like coughing during a chronic bronchitis flare-up.

Oysters
Oysters are a great source of nutrients like vitamin B, zinc, copper, and selenium, all of which have been linked to promoting lung health. According to studies, people with higher levels of selenium and copper in their blood are less likely to develop lung diseases. Vitamin B and zinc, too, are vital for promoting overall health and reducing the risk of COPD.

Edamame
Edamame beans contain isoflavones, which may reduce the risk of many health conditions, including COPD. A healthy intake of isoflavone can also help people improve their lung function and reduce the occurrence of shortness of breath.

Olive oil
Olive oil has concentrated amounts of antioxidants like polyphenols and vitamin E. These compounds protect people against lung diseases like asthma.

Coffee
Coffee is rich in caffeine and antioxidants, which can help promote lung health and function. Coffee helps open up the blood vessels, promoting blood flow. This process is known as vasodilation or bronchodilation and can temporarily help mitigate the symptoms of lung conditions like asthma. According to the FDA, adults may safely consume up to 400 milligrams of caffeine (or four to five cups of coffee) daily.

Yogurt
Yogurt contains nutrients like calcium, potassium, phosphorus, and selenium. All of these are associated with improved lung health and reduced risk of COPD.

Brazil nuts
Brazil nuts contain the highest amount of selenium, with one single nut possibly containing more than 150% of the recommended daily dose. A healthy intake of selenium may help build immunity against lung cancer, improve respiratory function, and improve overall lung health.

Lentils
Lentils contain copper, magnesium, potassium, and iron, which are essential nutrients for lung health. They are also a rich source of fiber and can help reduce the likelihood of COPD.

Cocoa
Cocoa products like dark chocolate contain flavonoids and theobromine. While the former has antioxidant and anti-inflammatory properties, the latter has been associated with relaxing the airways in the lungs, relieving the symptoms of lung conditions. These compounds may also help protect against lung cancer.

Anchovies
Anchovies are rich in anti-inflammatory nutrients like omega-3 fats, selenium, calcium, and iron. According to studies, higher consumption of omega-3 has been associated with improved lung function and reduced severity of conditions like COPD.

Swiss chard
Swiss chard, a dark leafy green vegetable, is a rich source of magnesium. Besides having anti-inflammatory effects, magnesium helps the bronchioles relax, reducing chronic bronchitis flare-ups. Lower levels of magnesium have been linked to more severe symptoms of COPD.

Barley
Barley is an excellent source of fiber, flavonoids, and vitamin E, which have all been shown to reduce the risk of lung diseases and improve overall health.

Making lifestyle changes and eating healthy foods is an excellent way to promote overall health and reduce the risk of lung disease. However, it is advisable to consult a doctor before making changes to the nutrition plan.

Top 6 foods that may reduce dementia risk

Many individuals mistakenly believe that dementia is a disease, but it’s a term used to describe symptoms related to memory, social abilities, and thinking. These symptoms can be challenging to manage and can impact daily activities. However, healthcare professionals often recommend implementing a healthy meal plan as a way to improve management. If you’re interested in learning about how your food intake can reduce the risk of developing dementia, read on. What is dementia? As previously mentioned, dementia is not a specific disease. Instead, health conditions like Alzheimer’s disease are among its most frequent causes in older adults. Other known causes of dementia include damage to the blood vessels that supply nutrients to the brain, the formation of balloon-like proteins in the brain, and the breakdown of connections and nerve cells in the brain. While memory loss is one of its most recognizable signs, this symptom alone does not mean one has dementia. Most symptoms of this group of health issues can vary depending on the cause. Hence, here are some of the most common signs to look out for. Memory loss Difficulties while communicating Reasoning and problem-solving issues Poor control of movements and coordination Disorientation Confusion What are the foods that can help reduce the risk of dementia? Typically, dementia and Alzheimer’s are known to be caused by a combination of several factors, such as environmental, lifestyle, and genetic. Furthermore, developing issues such as high blood pressure, diabetes, and heart disease can contribute to cognitive decline in patients. Therefore, healthcare professionals suggest the consumption of nutrient-rich foods to reduce dementia risk as one grows older. Some of the foods that can be added to one’s meal plan are: Avocados Avocados are one of the most commonly known superfoods, which can provide the brain with the needed energy without a spike in blood sugar levels.

Avoid these 15 common shower mistakes

There is nothing a warm shower cannot resolve. Showering after a long day can be a stress reliever and enhance one’s mood instantly. It also has several other health benefits besides cleansing the body, including facilitating cold relief, boosting immunity, and relieving muscle pain. However, not bathing the right way can give rise to skin conditions such as rashes and eczema. Here are some common mistakes one should avoid while bathing and showering: Not moisturizing after a shower Wiping after a bath can reduce the body’s moisture, causing dry skin, which can lead to rashes and itching. Dermatologists recommend applying body lotion and moisturizer immediately after a shower to retain skin texture and prevent dryness. One should look for hypoallergenic moisturizers that do not have any added fragrances. Bathing in scorching hot water Scorching hot water can damage keratin cells in the skin’s outer layer. Consequently, the skin becomes dry and dehydrated. It is important to balance the water temperature before stepping into the shower. Ideally, the temperature of the water should be lukewarm. Using the wrong towel An absorbent towel that does not feel rough is ideal for wiping oneself after a shower. The most effective way to select the right towel is to check its density, measured in grams per square meter (GSM). Towels with GSMs between 400 and 550 are considered ideal for use after bathing. One should avoid towels below a GSM of 400, as these towels can be thin and rough, causing skin dryness. Moreover, towels made of superior-quality Egyptian or Turkish cotton are extremely soft and perfect for the skin. Soaping the arms and legs excessively While it is important to wash and clean one’s arms and legs, these areas typically do not collect much oil and dust. Hence, scrubbing them excessively can dry out these areas and hamper their natural texture.

15 signs of a weak immune system

The immune system is a complex network of organs, cells, and proteins that act as the body’s defense mechanism against diseases and infections. The system —the innate immune system that people are born with and the adaptive immune system, which develops due to exposure to toxins and microbes. Both parts work together to keep infection-causing germs and toxins. So, weak immunity can make the body susceptible to diseases and other health issues. High stress levels The American Psychological Association suggests that chronic stress weakens the immune system. This is because stress lowers the number of white blood cells (i.e., lymphocytes) in the body that fight infections, increasing the risk of infections such as the common cold. Persistent cold Most adults develop two to three colds per year, which usually last from 7 to 10 days. During this period, the immune system forms antibodies to fight the virus. However, if one keeps catching a cold or is dealing with common cold symptoms for a long time, it could be a sign of weak immunity. Slow-healing wounds When one develops a cut or a wound, the body immediately goes into damage control mode to stop any bleeding and regenerate skin. Immune cells in the body guide this process. However, when dealing with a weakened immune system, wounds take longer to heal. This can make one more susceptible to infections as well. Frequent infections Those with a lowered immunity are at a higher risk of contracting infections such as pneumonia, meningitis, bronchitis, and skin infections. They are also more likely to experience autoimmune disorders, organ inflammation, blood disorders such as anemia, and growth and developmental delays. According to the American Academy of Allergy, Asthma, and Immunology, some signs of weak immunity include: – Having more than four ear infections in a year – Developing pneumonia twice within a year – Dealing with chronic sinusitis or more than three episodes of bacterial sinusitis in a year Fatigue If one constantly feels tired despite getting enough sleep, it may be a sign of weak immunity.
