10 ways to stave off colds and flu
Get more vitamin D
There’s plenty of controversy around the idea of taking vitamin C to stave off a cold, but there is some evidence to suggest that getting enough vitamin D can help reduce your risk of developing flu.
We absorb vitamin D mostly by exposure to daylight, but it’s also present in some foods, especially oily fish, dairy foods, fortified cereals and margarine. Most of us can get enough vitamin D by eating more of these foods and spending time out-of-doors without needing to take supplements.
