My son is allergic to molasses. Brown sugar is white sugar with molasses in it. I feel bad to because it took me 11yrs to figure out that he was a allergic to it. It is in a lot of prepackaged food. It cause him not to eat, throw up and gave him the runs.
A person can develop an allergy to anything.
Most allergies are to proteins. Maybe even all allergies. That's why no one is allergic to cream or butter; and that is why people with deadly allergies to peanuts can eat foods cooked in peanut oils. None of these foods contain any proteins.
But based on the number of people in my family allergic to brown sugar and molasses, I can tell you the answer to your question is "Yes."
