A study of over 30,000 Singaporean adult non-smokers has found a high incidence rate of chronic coughing stemmed from the secondhand smoke of their childhood In fact, adult non-smokers who were exposed to secondhand smoke as children are twice as likely to be afflicted by a chronic cough as an adult.

On the other hand, the study found that individuals who consumed diminutive amounts of fruits containing fiber were less apt to experience chronic coughing as a result of tobacco smoke.

The research team was comprised of scientists from the University of Minnesota, the National University of Singapore and the United States National Institute of Environmental Health Sciences (NIEHS). The trial has been named the most significant sized study on the consequences of environmental tobacco smoke exposure on childhood. It is the first evaluation to compare dietary intake with tobacco exposure.

In earlier clinical trials, the findings demonstrated a correlation between fruit consumption and reduced incidences of chronic respiratory symptoms. Additionally, there is evidence on how dietary vitamins such as vitamin C may prevent a child's respiratory health. The new medical findings show how fiber intake from vegetables and fruits (7.5 grams of fiber per day) is less affected by environmental tobacco smoke at a youthful age.

According to a researcher from NIEHS the Dr Stephanie London, fiber has been found to demonstrate health advantages on the lungs. It impacts the body by reducing concentrations of blood glucose, decreases inflammation, and enhances the antioxidant processes of the body. All of the attributes has been associated with the protections of the lungs against environmental result. In essence, foods high in fiber are associated with lowering the risks of secondhand smoke respiratory ailments.
