Mediterranean Diet Can Protect Against Adult-Onset Asthma, Study Finds

<span><a href="https://www.healthandme.com/health/asthma">Asthma</a></span> is usually associated with children. However, a large number of adults are diagnosed with asthma later in life, known as adult, onset asthma. A sharp contrast to childhood asthma, adult cases can be more long, lasting, difficult to control and very much influenced by environmental and lifestyle factors. 

Smoking, air pollution, and workplaces are three known risk factors, but experts in the field are opening up the research to include diet as a possible factor that can be changed. New research indicates our diets may play a big role in asthma development and following a <span>Mediterranean diet</span> may significantly lower overall risk by nearly 50 percent.

 The World Health Organization estimates that over 260 million individuals globally suffer from asthma. 

The Mediterranean diet is inspired by traditional eating patterns in countries bordering the Mediterranean Sea, particularly in places like Spain, Greece and Italy. It recommends eating:

<ul><li>Fruits and vegetables</li><li>Whole grains</li><li>Legumes and nuts</li><li>Olive oil as the primary fat source</li><li>Moderate fish consumption</li><li>Limited red and processed meats</li></ul>

This diet is well known for its cardiovascular benefits and its strong anti-inflammatory and antioxidant properties have prompted scientists to explore its impact on respiratory health.

<h2>The Study That Sparked Attention</h2>

A large, scale prospective study through the <span>Seguimiento Universidad de Navarra</span> (SUN) Project aimed at finding out if a Mediterranean diet could lower asthma in adults. The project, done by the team at Universidad de Navarra, included data from more than 17,000 university graduates who were tracked for almost 13 years in Spain.

The study participants did not have asthma at the time of registration. Their food intake was assessed through a validated Mediterranean Diet Score (scale of 0 to 9), and incidences of asthma were recorded with the help of follow, up questionnaires.

The study showed that people sticking to the Mediterranean diet the most became adults with asthma 42 percent less than those who followed the diet the least. Additionally, after changing for confounders like age, smoking, physical activity and BMI, this protective effect was still significant from the statistical viewpoint.

The study results were covered by EMJ Reviews and appeared among respiratory research publications, thus attracting the attention of the makers of the next major public health policy measure.

<h2>Why Does Diet Affect Asthma?</h2>Essentially, asthma is an inflammatory disease as chronic inflammation of the airways causes the narrowness of the bronchi which results in symptoms. The Mediterranean diet is rich in:

<ul><li>Omega-3 fatty acids from fish, which help regulate inflammatory pathways</li><li>Polyphenols and antioxidants from fruits and vegetables, which reduce oxidative stress</li><li>Healthy monounsaturated fats from olive oil, which may support immune balance</li></ul>

<h2>What To Remember </h2>The results are promising but one should keep in mind that this was an observational study. This means that the researchers found associations but not direct cause, and, effect relationships. Diet was self, reported, and although the researchers made adjustments for various confounding factors, there is always a possibility of residual bias.

Some previous cohort studies have yielded inconsistent results, and experts concur that randomized controlled trials would produce more reliable evidence.

<h2>The Bigger Picture</h2>Despite the different restrictions, the investigation still contributes to the increasing volume of literature indicating that diets affect not only cardiac health or body weight but could have impacts on lung health as well. Since diet is a changeable element by an individual, encouraging Mediterranean, type eating habits might be considered among the comprehensive approaches for forestalling chronic inflammatory diseases, such as asthma.

Though additional research is necessary to be sure, the main idea is increasingly conspicuous: our diet today might determine our respiratory health over the next several years.
