What are the results of nutritional epidemiology regarding the relationship between diet and respiratory disease?

This article explores the relationship between our eating habits and respiratory disease. In my role as a nutritionist and dietician, I'll guide you through the most important research findings that show how diet can influence respiratory health. This link will be discussed, as well as how you can incorporate this knowledge into your daily life.

It is important to understand the link between diet and respiratory diseases

It is important to understand the link between diet and respiratory disease for prevention and treatment. Scientific evidence is growing that suggests certain diet components may either ameliorate or worsen respiratory problems. A study in the European Respiratory Journal, for example, found that eating a lot of fruit and vegetables is associated with better lung health and lower risks of chronic obstructive respiratory disease (COPD). In contrast, diets rich in refined sugars and processed food have been associated with worsened COPD symptoms and asthma.

Get Started: Integrating nutritional findings into your lifestyle

In order to benefit from these studies, you should focus on adding nutrient-rich food that supports respiratory health into your daily diet. It is important to be aware of which nutrients are beneficial for lung health, and what foods contain these nutrients. American Lung Association suggests foods high in antioxidants that can reduce inflammation of the lungs. It is also important to limit the consumption of foods high in sugar, unhealthy fats and processed food. These can lead to inflammation and worsen respiratory problems.

Other Tips on Diet and Respiratory health

Other lifestyle changes can improve respiratory health beyond diet. Regular exercise can boost your immunity and strengthen your lungs, making you less susceptible to respiratory infections. Smoking and secondhand smoking can damage the lungs directly. Maintaining a healthy body weight will also help prevent the respiratory issues associated with obesity such as asthma and sleep apnea.


Summary: Nutritional epidemiology provides valuable insight into the relationship between diet and respiratory disease. Diets rich in vegetables, fruits, grains and proteins, such as lean meats, can protect from respiratory diseases and help manage the symptoms of those who already suffer. We can improve our respiratory health by making healthy dietary decisions and living a healthier lifestyle.
