Loads of us live in polluted areas, which can contribute to health problems like lung disease. Scientists have found that taking extra B vitamins might stop harmful particles from causing changes in our DNA and disrupting our immune systems. Only ten people took part in this experiment, so much bigger studies will be needed to show if these benefits are real.
Protection against harmful emissions is important, but I think we should be working harder to reduce pollution levels as well. It would improve our health, as well as helping the natural world too.
