If you live in the US and drink Mountain Dew and some other citrus-flavored sodas and sports drinks, then you are also getting a dose of a synthetic chemical called brominated vegetable oil (BVO), which was originally patented by chemical companies as a flame retardant.
BVO has been shown to bioaccumulate in human tissue and breast milk, and animal studies have found it causes reproductive and behavioral problems in large doses. Bromine is a central nervous system depressant, and a common endocrine disruptor. It’s part of the halide family, a group of elements that includes fluorine, chlorine and iodine. When ingested, bromine competes for the same receptors that are used to capture iodine. This can lead to iodine deficiency, which can have a very detrimental impact on your health. Bromine toxicity can manifest as skin rashes, acne, loss of appetite, fatigue, and cardiac arrhythmias.
Where it’s banned: Europe and Japan
According to the featured article:
“The FDA has flip-flopped on BVO’s safety originally classifying it as ‘generally recognized as safe’ but reversing that call now defining it as an ‘interim food additive’ a category reserved for possibly questionable substances used in food.”
