Allergic

                   

Why are some people allergic?
Some people are allergic and most of them  are allergic to dust or milk to the most common but there are are people who have allergies to more things due to pollution.
They say that it is due to contamination, before we did not know what they were allergic to, but now there is medication to remove allergies or reduce them.
we must pollute less and put  less sugar into the food we eat cannot eat.
I know people who have many allergies and do not feel well and can not eat all the food.
