Summary
A 10.5-year analysis of 179,062 participants found people with the highest vitamin K1 intake had a 16% lower likelihood of COPD and better lung function.
Leafy green vegetables such as spinach, kale and broccoli are major vitamin K1 sources, and researchers said the association was strongest in smokers and people in high-risk occupations.
Vitamin K2 showed no link to lower COPD rates, and neither vitamin K1 nor K2 was associated with asthma in the study published in The American Journal of Clinical Nutrition.
Chronic respiratory diseases affected 454.6 million people and caused 4 million deaths in 2019, the researchers said, highlighting demand for prevention even though the observational study cannot prove causation.
