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.
BHA (butylated hydroxyanisole) and BHT (butylated hydroxytoluene) are widely used by the food industry as preservatives, mainly to prevent oils in foods from oxidizing and becoming rancid. Oxidation affects the flavor, color and odor of foods and reduces some nutrients.
