Research published in the online open journal "ERJ Open Research" in August pointed out that vitamin K protects the lungs, while green leaves vegetables are rich in vitamin K.

Denmark scientists found that subjects with low vitamin K content in the body have poor lung function and are prone to asthma, asthma and obstructive pulmonary disease (COPD). The impact of vitamin K on the human lungs has not been widely known in previous studies.

Researcher Torkil "We already know that vitamin K is important for blood, heart and bone health, but few studies have explored the relationship between vitamin K and the lungs. Our study shows that vitamin K is important for maintaining lung health."

Danish researchers from the University of Copenhagen Hospital and the University of Copenhagen followed 4,092 subjects, ranging from 24 to 77 years old, all living in Copenhagen. The researchers conducted the pulmonary function and respiratory tests of the subject's so-called "spirometry" to test how much air the subject's lungs can inhale and exhale, as well as the difficulty and speed of vomiting air from the lungs.

The researchers also used blood tests to observe changes in the "matrix gla protein" (dp-ucMGP) with low vitamin K content, and evaluated the overall health and lifestyle of the subjects in the questionnaire.

The results of the study show that people with less vitamin K content have poor lung function, and these people have a higher chance of having asthma, asthma and chronic respiratory diseases.

Vitamin K is not only hidden in green vegetables like green cauliflower and spinach, but also has its own effects in vegetable oil and grains, and it is also helpful for wounding, protein required for blood coagulation, and creating healthy bones.
