Vitamin D 'key for healthy lungs'

    Vitamin D could play a role in keeping the lungs healthy, research suggests.

    Patients with higher vitamin D levels in their blood had significantly better lung function, a University of Auckland team found in a study of 14,091 people.
    The difference between the two was more marked than that between smokers and those who had quit, the study published in the journal Chest said.

    Dietary supplements could boost lung function, the team suggested, but they added that more research was needed.

    "Low levels of vitamin D have been associated with osteoporosis, hypertension, diabetes, and cancer," said lead researcher Dr Peter Black.

    "Our research shows that vitamin D may also have a strong influence on lung health, with greater levels of vitamin D associated with greater and more positive effects on lung function."

    Dr Black said the difference in performance between those with the highest and lowest concentrations of vitamin D was more marked that the difference between non-smokers and those who had given up.

    The team found that those people with the highest concentration of vitamin D in their blood significantly outperformed others in tests to measure their lung function.

    However, he said: "Although there is a definite relationship between lung function and vitamin D, it is unclear if increases in vitamin D through supplements or dietary intake will actually improve lung function in patients with chronic respiratory diseases."

    The tests included:
    i The FEV1 test which measures the volume of air that can be forced in one second after taking a deep breath.
    ii The FVC test which measures the total volume of air that is expelled after taking a deep breath

    The researchers found vitamin D was higher in men than women, was inversely related to obesity levels, and declined with age.

    It was also lower in participants smoking more than 20 cigarettes a day compared with non-smokers.

    Dr Peter Black said he was not sure why vitamin D has this effect on lung function.

    But he suggested it may be because vitamin D affects the repair and remodelling of lung tissue, which goes on throughout life.
    "The effects of vitamin D are not limited to bone and there is evidence that it can affect the growth of a wide variety of cell types."

    Rib cage?
    Dr Mark Britton, a spokesman for the British Lung Foundation, told the BBC News website that it was likely that vitamin D had an impact on the development of the rib cage, rather than the lung tissue itself.

    He said that failure to develop strong bones could impact on the size of the lungs.

    Dr Michael Alberts, president of the American College of Chest Physicians, said: "Chronic lung conditions compromise quality of life for millions of people around the world.
    "By understanding the effect that vitamins have on lung function, we may be able to identify new and more effective treatments for these debilitating diseases."

    Vitamin D is essential for the processing of calcium.
    Unlike other vitamins, it can be made in our bodies as a result of exposure to sunlight, providing the necessary starting materials are there to start with.

    It is also contained in a few foods including oily fish, fish oils, butter and eggs.

    This has already been posted here before but it does indicate how important Ca and vit D can be. There has been so much written about the need for Mg, often with advice not to take Ca at all. What is becoming clearer is the need for Ca, Mg and vit D; all have important roles and work synergistically.


    Right diet 'could help stop PMS'
    A diet rich in calcium and vitamin D might banish pre-menstrual syndrome (PMS), US researchers believe.
    Many women experience mild emotional or physical symptoms before their period, but 20% have more severe symptoms.

    Massachusetts University researchers compared the diets of 1,000 women with PMS and 2,000 women without PMS.

    Those without PMS tended to eat more vitamin D and calcium-rich foods like milk, cheese, broccoli and cereals, the Archives of Internal Medicine reported.

    Daily intake

    Others have already reported that calcium supplements appear to ease PMS, but the new research suggests both calcium and vitamin D might reduce PMS risk in the first place.

    Although the authors did not look at what might be behind the link, past studies suggest calcium and vitamin D may influence levels of the female hormone oestrogen.

    This provides a basis for a good randomised, placebo-controlled trial to see whether this is a real effect

    Researchers have also shown that blood calcium and vitamin D levels are lower in women with PMS.

    There are several theories about why PMS occurs, but some believe it is triggered by fluctuations of the sex hormones during the menstrual cycle - a drop in progesterone or the increase in oestrogen during the latter half of the menstrual cycle.

    In the current study, after adjusting for factors like the woman's age, how many children she had and whether she smoked, the researchers found the women with the highest intake of vitamin D and calcium were significantly less likely to have PMS.

    Scientist Elizabeth Bertine-Johnson said: "We observed a significantly lower risk of developing PMS in women with high intakes of vitamin D and calcium from food sources, equivalent to about four servings per day of skim or low-fat milk, fortified orange juice or low-fat diary foods such as yoghurt."

    The amounts consumed were slightly above the current recommended daily amounts in the UK, which are 800 milligrams of calcium and 5 micrograms of vitamin D.

    Vitamin D is known to help the body absorb calcium and both are essential for healthy bones.

    Professor Shaughn O'Brien, an expert on PMS from Keele University, said the findings provided a basis for clinical trial to see whether this was a real effect.

    He said following a healthy, balanced diet was sensible for anyone and that there are drug treatments have been shown to be helpful for women with severe PMS.

    These include antidepressants, which appear to ease the physical as well as the psychological symptoms, he said.

    The study authors agreed that clinical trials were warranted.

    "In the interim, given that calcium and vitamin D may also reduce the risk of osteoporosis and some cancers, clinicians may consider recommending these nutrients even for young women," they said.
