Apple juice and apple consumption has been shown to benefit lung health and also to help combat asthma. In this article I’m going to briefly cover and link to different studies that have demonstrated both of these to be true.
If you suffer from asthma or are looking to improve the health of your lungs, you’ll find this article of great interest! Also included is information about apples and apple juice decreasing the risk of lung cancer.
While many of the studies found that apples and apple juice were both equally effective, a few of them found that apple juice was more effective.
I personally both juice apples and eat them.
How Apple Juice Is Good For Your Lungs
General Lung Health, Including, Chronic obstructive pulmonary disease
Study #1. Lung Health
A study published in the Journal of Environmental Pathology Toxicology and Oncology found that apple juice benefited the lungs. In this study apple juice “reduced Cr(VI)-induced lipid peroxidation, DNA damage, cell apoptosis, and NF-kappaB activation in human lung epithelial A549 cells.”
Translated: It was concluded that apple juice, through its antioxidant properties, reduces cellular injury to the lungs and may help reduce carcinogenic damage.
Study #2. Lung Health
There was a study conducted in Caerphilly, Wales with the purpose of investigating associations between diet and lung function. The focus of this study was 2,512 Welshmen whose ages ranged between 45-59.
It was concluded that there was a strong positive association between lung function and the number of apples eaten per week. Vitamin E was also indicated to be helpful for lung function in this study.
Study #3. Lung Health
A study published by The American Journal of Respiratory and Critical Care Medicine focused on chronic obstructive pulmonary disease and intake of catechins, flavonols, and flavones.
Before I briefly cover the details of this study, a couple of definitions will be necessary.
What Is COPD?
Chronic obstructive pulmonary disease (COPD) is an umbrella term used to describe chronic and progressive lung disease that makes it hard to breath. COPD includes bronchitis, emphysema, refractory (non-reversible) asthma, and some forms of bronchiectasis.
What Are Catechins and Flavonols?
Back To The Study
Tea and apples were used in this study as the main source of catechins, flavonols, and flavones. The results of the study suggested that there was a beneficial effect against COPD when a high intake of catechins and solid fruits were consumed.
Pears and apples, more so, showed a stronger association with the positive benefits than other fruits. Apples were mentioned the most in this study, and it was hypothesized that apples might have been beneficial due to their high level of flavonoids.
Apple Juice and Lung Cancer
A research paper published in the Nutrition Journal on May the 12th, 2004, focusing on apple phytochemicals and their health benefits, had quite a bit to say about the benefits of apple consumption for lung cancer.
This paper cited several studies that specifically linked apple consumption with a reduced risk for cancer, especially lung cancer.
One of the studies included 77,000 women who reduced their risk of lung cancer by 21%. Fruit and vegetable intake was associated with this reduced risk.
What was interesting about this study was that while very few of the individual fruits and vegetables examined had a significant effect on lung cancer risk, apples did. Other than pears, they were the only other vegetable or fruit that was singled out as being beneficial for decreasing the risk of lung cancer.
Another study cited in the research paper indicated that the flavonoid quercetin, which is found in high amounts in apples and homemade apple juice, was responsible for a 40%-50% decrease in the risk of cancer for 582 patients with cancer as well as 582 control subjects without cancer! This decreased risk was seen in men and women and almost all ethnic groups.
Yet another study cited in the research paper involved 10,000 Finnish men and women and included a 24-year follow-up! Apples were noted as being the only specific food that helped to reduce the risk of lung cancer.
Apple Juice For Asthma
Below, I’ve briefly summarized a few studies concerning apple juice and its anti-asthma benefits.
Study #1. Asthma
This cross-sectional study of 1,601 young adults in Melbourne, Australia found that apples and pears appeared to protect against current asthma, asthma in general, and bronchial hyper-responsiveness (BHR).
Study #2. Asthma
This study involving 10,054 Finnish men and women found that the incidence of asthma was lower when the intake of quercetin was higher. As mentioned previously, quercetin is an antioxidant found in abundance in apples and apple juice.
Study #3. Asthma
The BBC news network cited a study suggesting that “children who drink plenty of apple juice may be less likely to develop asthma symptoms” (BBC news). The study, published in the European Respiratory Journal, looked at five to 10-year-old schoolchildren. It was discovered that “those who drank apple juice at least once a day were half as likely to suffer from wheezing as those drinking it less than once a month.”
Dr Mike Thomas, an asthma researcher, stated that this study “was further evidence of the protective effect of apples.”
What I personally found interesting about this study, was that eating apples had no effect in itself; it was only apple juice that appeared to be effective. This hasn’t been true with many of the other studies I cited above but for some reason it was the case here.
Wrapping It Up
If you’re looking into juicing for lung health or to combat or prevent asthma, the studies I cited in this article, most definitely, seem to indicate that drinking apple juice is a good idea.
You can drink apple juice straight, but I always suggest that people consider including multiple ingredients in at least some of their juice recipes. The reason for this is that you will get a wider spread of nutrients into your body.
