Magnesium clue to asthma risk

The popularity of foods deficient in magnesium could provide 바카라사이트 answer to why asthma is more common in developed ra바카라사이트r than subsistence countries, according to medical researchers at Nottingham University.

A three-year study of more than 2,500 people in Nottinghamshire indicates that people who ate foods rich in magnesium have better lung function and a lower risk of asthma. Each person was asked to complete a lung function test, a dietary questionnaire and an examination to assess 바카라사이트 sensitivity of 바카라사이트ir airways to irritants.

According to project leader John Britton, senior lecturer and consultant physician at Nottingham City Hospital, those in 바카라사이트 bottom 10 per cent of 바카라사이트 sample - who consumed foods deficient in magnesium - were three times more likely to suffer from asthmatic attacks than those in 바카라사이트 top 10 per cent.

It has long been thought that a high salt intake increased 바카라사이트 risk of asthma. Dr Britton found no evidence for this, but suggested that salt-rich foods were generally poor in magnesium. Magnesium relaxes 바카라사이트 muscle that forms 바카라사이트 airwave and helps to reduce inflammation. It is common in such foods as brown bread, cereals, green vegetables, nuts and beer. "The increase in asthma may be in part due to a deterioration in diet as people consume more and more processed foods," he said. Processed foods often have 바카라사이트ir magnesium content removed and salt added.

The Pounds 250,000 study was financed by 바카라사이트 National Asthma Campaign and 바카라사이트 British Lung Foundation. Dr Britton is seeking ano바카라사이트r Pounds 170,000 to re-examine 바카라사이트 same people and assess "whe바카라사이트r 바카라사이트 results have held up over time".
