In The Huffington Post there was an article written on the ingredient BVO also known as Brominate Vegetable Oil. It is found in fruit flavored drinks, and sodas in the United States. It is an additive in these drinks that weights down the citrus flavoring so it mixes with the liquid and doesn't separate. BVO is currently banned in Europe and Japan, and they use a chemical of a hydrocolloid compound that does the same thing, without the negative side effects. BVO was originally patented by chemical companies as a flame retardant, and is also used as by furniture makers who spray it on their furniture like mattresses and sofas. It current exist in 10% of soda and fruit flavored drinks within the United States. It builds up in the human tissue and has been found excreted in breast milk. It is also linked to neurological, reproductive and behavioral problems. The FDA banned the substance in the 1970's then decided to allow it back on the market. Overall, there is little data to prove its not harmful. Many feel that with the advancements of science, there should be more studies done to test again. What are your thoughts?
