Foods Containing Sulfiting Agents
Sulfites are salts of sulfurous
acid containing the ion SO. These are added to wine, dried fruits, bottled
lemon juice and some fruit juices in order to prevent oxidation and spoilage.
Common Allergens
Many common allergens are also
likely to cause asthma and these include milk, eggs, peanuts, soy, wheat,
shellfish and fish. Particularly of course if you are aware of any allergens it
is a good idea to avoid these (however food allergies only contribute to around
5% or less of asthma cases).
Hairy Fruits
The hairs on some fruits can
trigger the effects of asthma and are easily avoided.
Binders
Binding foods such as bananas and
rice can potentially trigger asthma attacks, as might those foods which are
high in starch. If you find difficulty in chewing and swallowing then these
might contribute.
In extreme cases patients may be
admitted to hospital where they will undergo an 'exclusion diet'. This is a
diet designed to be low in everything, in order to see if the symptoms subside.
