Please [[User:DOI_bot/bugs|report any bugs]]. '''Brominated vegetable oil''' (BVO) is [[vegetable oil]] that has had atoms of the [[Chemical element|element]] [[bromine]] bonded to it. Brominated vegetable oil is used as an [[emulsifier]] in [[citrus]]-flavored [[soft drinks]] such as [[Mountain Dew]], [[Gatorade]], [[Powerade]], [[Mello Yello]], Pineapple and Orange [[Fanta]], [[Sun Drop]], [[Squirt]] and [[Fresca]] to help natural fat-soluble citrus flavors stay suspended in the drink and to produce a cloudy appearance. The addition of bromine increases the [[density]] of the oil, and the amount of bromine is carefully controlled to achieve a density that is the same as the [[water]] in the drink. As a result, the BVO remains suspended in the water instead of forming separate layers. == Health effects == Long after consumption of BVO in test animals, traces remain in the [[body fat]].{{Fact|date=June 2007}} Bromine is a [[halogen]] and displaces [[iodine]], which may depress [[thyroid]] function. Evidence for this has been extrapolated from pre-1975 cases where bromine-containing sedatives resulted in emergency room visits<ref name="sdreader">{{cite web |url=http://www.sdreader.com/php/ma_show.php?id=168 |title=Straight from the Hip: What is Brominated Vegetable Oil? |author=Matthew Alice |publisher=San Diego Reader |date=[[1999-07-29]] |accessdate=2007-09-17 }}</ref> and incorrect diagnoses of [[psychosis]] and [[brain damage]] due to side effects such as [[depression (mood)|depression]], memory loss, [[hallucinations]], violent tendencies, [[seizures]], cerebral [[atrophy]], acute irritability, tremors, [[ataxia]], confusion, loss of peripheral vision, slurred speech, stupor, tendon reflex changes, photophobia due to enlarged pupils, and extensor plantar responses.<ref>{{cite web |url=http://www.gulflink.osd.mil/library/randrep/pb_paper/mr1018.2.chap10.html |title=A Review of Scientific Literature as it Pertains to Gulf War Illness, Volume 2: Pyridostigmine Bromide, Chapter Ten |author=Beatrice Alexandra Golomb |publisher=[[RAND]] |accessdate=2007-09-17 }}</ref> In one case, a man who drank eight liters of [[Grapefruit|Ruby Red]] [[Squirt]] daily had a reaction that caused his skin color to turn red and produced [[lesion]]s diagnosed as [[bromoderma]].
