Chronic cough is a common and often debilitating condition, with one study finding that women with unexplained chronic cough and iron deficiency saw significant improvement after iron supplementation. This surprising link between a vital mineral and a persistent respiratory symptom highlights the complex role of iron in overall health.

A study showed that consuming beetroot juice can significantly increase FeNO levels by over 20% within 45 minutes, demonstrating how a patient's diet can directly impact the results of a fractional exhaled nitric oxide (FeNO) test. This critical piece of information is essential for anyone preparing for this diagnostic procedure to ensure the accuracy of their results.

Did you know that up to 30% of infants experience wheezing in their first year of life? While often a symptom of asthma or infections, certain nutritional deficiencies, notably low vitamin D and magnesium levels, can significantly contribute to the inflammation and airway constriction that cause wheezing. This complex relationship highlights the critical role of diet in respiratory function.

According to scientific guidelines, consuming caffeine may lead to a transiently altered fractional exhaled nitric oxide (FeNO) value, and evidence suggests that coffee may actually decrease these levels, rather than increase them. This counterintuitive finding has significant implications for patients undergoing FeNO testing for conditions like asthma. Knowing the real impact of coffee is crucial for ensuring accurate test results and proper clinical management.

Studies have shown that vitamin D deficiency is highly prevalent among asthmatic patients globally. While no single factor 'causes' asthma, research suggests that low levels of certain vitamins, especially vitamin D, can increase the risk and severity of this chronic respiratory condition. Understanding this link can be crucial for managing the disease.

Studies have revealed a consistent link between lower dietary magnesium intake and reduced lung function, as well as an increased risk of asthma and chronic obstructive pulmonary disease (COPD). Given that magnesium is vital for numerous bodily functions, including muscle relaxation and inflammation control, research is exploring the extent to which **does magnesium improve lung function**.

Medical test results can be significantly influenced by dietary intake, and FeNO measurements are no exception. The question of **how does coffee affect FeNO?** yields conflicting evidence in medical literature, with some studies suggesting a decrease while others find no significant acute change.
