London, Apr 16 : A diet low in vitamins A and C could raise the risk of asthma, says a new study.
A Nottingham University-led team reviewed 40 studies carried out over the past 30 years and found that people with a low intake of vitamin C had a 12 percent increased risk of asthma, the Thorax journal reported.
The team said, for vitamin A the raised risk was less clear cut but there was still a significant association.
