Causes of food allergies rashes
Food rashes are caused by intaking food not very suitable to the immune systems of the body. Further, the immune system fights all the harmful substances. The most common allergens are eggs, peanuts, milk, soy, wheat, shellfish, etc. There are also chances of cross-reactivity. For instance, if you are allergic to shellfish, you might be allergic to seafood as well. Food allergies can be easily detected right from childhood. Doing skin tests and blood tests help in proving food allergies. Likewise, Allergies can develop in adults as well, but this is very rare.
The only way of preventing food allergies is to avoid the food item altogether. Read the food labels before purchasing groceries.
