Lack of vitamins A and C could raise asthma risk

LONDON: A diet low in vitamins A and C could raise the risk of asthma, says a new study by British scientists.
    A Nottingham Universityled team reviewed 40 studies carried out over the past 30 years, and found that people with a low intake of vitamin C – found in fruit and vegetables – had a 12 per cent increased risk of asthma.
    The raised risk was less clear cut for vitamin A – found in cheese, eggs and oily fish – but there was still a significant association. While they were unable to put an exact figure on this group, the scientists noted that those with severe asthma consumed only half the recommended intake.
    To reach the conclusion, researchers analysed relevant reports on both children and adults published since 1980.
    “Our findings indicate that low levels of vitamin C intake – and, to a lesser extent, vitamin A – are consistently associated with asthma risk to a degree that, if causal, would be sufficient to be clinically relevant,” lead researcher Dr Jo Leonardi-Bee wrote in the Thorax journal.
