Eating fast food three times a week may lead to asthma and eczema in children, say researchers who have looked at global disease and dietary patterns.
Almost 10,000 people born in Britain in 1958 were tracked for 15 years and researchers were able to identify which jobs were linked with an increased risk of developing asthma as an adult. It was found that the workplace had a greater influence on adult-onset asthma than smoking, accounting for one in six cases of the disease compared with one in nine for smoking.
Children whose mothers took antibiotics while they were pregnant were slightly more likely than other kids to develop asthma in a new Danish study.
Children who eat three or more hamburgers a week may be more likely to develop asthma than children who eat fewer burgers, according to a study published in the journal Thorax.
Asthmatics with low levels of vitamin D may suffer more severely from the disease than patients with sufficient levels of the vitamin, according to a study conducted by researchers from National Jewish Health in Denver and published in the American Journal of Respiratory and Critical Care Medicine.
Low levels of vitamin D are associated with lower lung function and greater medication use in children with asthma, according to researchers at National Jewish Health.
The U.S. Food and Drug Administration (FDA) recently issued new restrictions for four popular long-acting asthma drugs. Novartis AG's Foradil, GlaxoSmithKline's Serevent and Advair, and AstraZeneca's Symbicort, all contain an ingredient that relaxes airway muscles in the lungs which can cause asthma-related death.
Asthma sufferers could be helped by eating blackcurrants. The natural chemicals in the fruit may reduce lung inflammation, and so improve breathing during an asthma attack.
Low dietary intakes of vitamins A and C may increase the risk of developing asthma, suggests a review of 40 studies and 30 years of research.
Low blood levels of vitamin C and lower dietary intake of vitamin C-containing foods were associated with a 12 per cent heightened risk of asthma, say findings published online in Thorax.
