If he had autism he wouldn't be very social, but very shy. I don't think flapping his arms is a sign of autism, but if you're concerned about it, ask a neurologist about it, or his doctor, either way. :) â¥ Cute T â¥ Â· 9 years ago.
If it weren't for food preservatives, we couldn't enjoy many of the great foods the world has to offer. Common antimicrobial preservatives include sodium nitrate, calcium propionate, disodium EDTA, potassium sorbate, sodium benzoate, and sulfites.
Sulfites are chemical preservatives used in a range of foods including beverages such as wine and beer. They are added to processed foods to increase their shelf-life and even to some medications to keep them stable. Sulfites can trigger allergic reactions in some people, mainly those having asthma.
