Asthma is triggered by weather, dust and sometimes food such as onions, with symptoms like tight chest, shortness of breath, persistent cough, wheezing and more and a lot of things trigger it including weather, dust and food.
For food these ones are to be avoided as much as possible:
1. Beer, Wine, Hard Cider and Tea
The sulfites these food contains makes breathing difficult which could set up a bad reaction.
2. Shrimps (frozen)
Frozen shrimps are no nos for people with asthma as the preservative/additive in frozen ones contain sulfites that can trigger a deadly episode of the condition.
3. Dried fruits/Vegetables
Dried veggies and fruits/snacks get in the way of normal breathing apart from being obviously choking, they can trigger asthma episodes
4. French fries/Fried yam
These fried foods trigger asthma, if you have this condition its better to eat these food baked instead of fried.
