Soya in Chicken 大豆過敏者注意:雞也可能令你過敏?

Soya in chickenReaders will remember that in the November Foods Matter (p17) and on the FM website athttp://tinyurl.com/3adyvy, Tracy Smith, Jacqui Broadway and Julie Rogers all reported that,being ultra-sensitive to soya, they reacted to chickens and eggs that had been fed a soya dietthroughout their lives although they could tolerate organic chickens which had only been fed soya before slaughter.Professor Jonathan Brostoff said that this was an area in which very little work had been done; the laboratories we consulted said that they thought it was very unlikely that any soya residues would remain in the flesh.Jacqui Broadway decided to test this out and sent a piece of organic chicken to be analysed using the ELISA method (see opposite).The laboratory was right – the test did not detect any soya. We then sent a piece of ‘normal' chicken, which had presumably been fed soya all its life, for DNA testing – but with no more positive a result.But the fact remains that three of our readers (and how many other people) who are proven to be soya sensitive, become ill after eating chickens or eggs that have been fed a diet high in soya and do notafter eating chickens fed a diet very low in soya.Are they imagining their symptoms? Or are the tests currently available simple not sensitive or sophisticated enough to pick up the soya residues to which they are reacting?(Source: FoodsMatter)
