A glass of apple juice a day 'can help keep asthma away'
A glass of apple juice a day 'can help keep asthma away'Last updated at 09:36 05 June 2007
Drinking apple juice could halve the risk of developing asthma, say researchers.
Eating a banana can cut the risk by a third, according to the same study,
but consuming whole apples appears to have no affect.
Experts believe the epidemic of asthma in developed countries could be linked to a move away from natural, fresh foods to fast foods.
The latest study, published in the European Respiratory Journal, looked at almost 2,700 primary school children and
found those drinking apple juice at least once a day were 50 per cent less likely to develop asthma symptoms.
Researchers led by Professor Peter Burney at the National Heart & Lung Institute, Imperial College London,
were surprised the juice was more protective-than eating apples - or any other fruit other than bananas.
Professor Burney said: "It's probably dose-related, and the children drink more of the content from apples through juice than by eating the fruit."
Parents of children aged five to ten years living in South London were asked how much fruit and juice their children were consuming.
Professor Burney said the study was observational so did not give clear guidance on a recommended amount of juice.
"The results show at least a glass a day has an effect and it's a good idea to increase the amount of apple juice children are drinking," he added.
A Greek study has found children who eat a Mediterranean diet full of fruit, vegetables and nuts are less likely to develop asthma and allergies.
研究也發現，兒童每天喝一杯蘋果汁的話，產生氣喘症狀風險也會減少百分之四十七。
美國康乃狄克大學研究團隊另進行動物實驗，測試鳳梨酵素的功用，在八天研究中，鳳梨酵素讓老鼠體內的白血球細胞數目明顯下降，
氣喘發炎指標「嗜伊紅性白血球」也減少約百分之五十。
過去研究認為，攝取維生素C、維生素E等抗氧化營養素，有助減少氣喘發作。深色蔬菜、水果抗氧化成分特別多。
也有部分研究發現，氣喘患者體內的某些抗氧化營養素濃度較一般人低，如維生素C、乙型胡蘿蔔素等
Although drinking apple juice helps prevent developing asthma, consuming a whole apple seems to have no effect
雖然飲用蘋果汁有助於防止降低哮喘機率，但是吃掉整個蘋果卻沒有任何的效果 |
