Healthy dietary patterns are associated with a lower risk of developing chronic obstructive pulmonary disease (COPD), according to a new study published in ERJ Open Research.
The study implicated a number of studies derived from seven databases released between early-1980 and late-2019. Data from eight observational-related studies, though, were analyzed to establish outcomes on COPD risk from healthy and unhealthy dietary patterns.
The findings demonstrated an association between healthy dietary patterns and a lower prevalence of COPD.
“While previous research has mainly investigated the effects of individual nutrients and food groups on COPD, the investigation of the combined effects of overall dietary patterns is an important area of ongoing research,” the findings read.
“Our findings suggest consumption of unhealthy dietary patterns was associated with higher risk of COPD; however, the findings were not statistically significant and had high heterogeneity. While subgroup analysis and investigation for publication bias would be ideal to explore potential causes of this heterogeneity, this was not possible due to insufficient study numbers,” the study concluded.
