Large study suggests people with low levels of vitamin K have less healthy lungs

People with low levels of vitamin K in their blood are more likely to have poor lung function and to say they suffer with asthma, chronic obstructive pulmonary disease (COPD) and wheezing, according to a study.

Vitamin K is found in leafy green vegetables, vegetable oils and cereal grains. It plays a role in blood clotting.

Researchers say their new findings do not alter current advice on vitamin K intake, but they do support further research to see if some people could benefit from taking vitamin K supplements.

The study involved a group of 4,092 people aged between 24 and 77 years living in Copenhagen.

Study participants took part in lung function testing, called spirometry, gave blood samples and answered questionnaires on their health and lifestyle. The blood tests included a marker of low levels of vitamin K in the body called dp-ucMGP. Spirometry measures the amount of air a person can breathe out in one second (forced expiratory volume or FEV1) and the total volume of air they can breathe in one forced breath (forced vital capacity or FVC).

The researchers found that people with markers of low levels of vitamin K had lower FEV1 and lower FVC on average. People with lower levels of vitamin K were also more likely to say they had COPD, asthma or wheezing.

Researcher, Dr. Torkil Jespersen said, "We already know that vitamin K has an important role in the blood and research is beginning to show that it's also important in heart and bone health, but there's been very little research looking at vitamin K and the lungs. To our knowledge, this is the first study on vitamin K and lung function in a large general population. Our results suggest that vitamin K could play a part in keeping our lungs healthy."

Every nutrition study in the last 60 years includes this phrase. They can't let nutrients compete with big pharma.
