Hello, my son is allergic but he eats a lot of musli, which is made 54% of wheat, 4% honey, palm oil, caramel syrup and may contain traces of dairy and soya products. The thing is that we knew he's allergic to some exterior factors, such as dust, but lately he coughes all the time, especially at night,for about 2 or 3 months now. And today I thougt that maybe these musli are the cause. My question is can allergic person use musli ?
