Brominated Vegetable Oil Claim: Article warns about the dangers of brominated vegetable oil in Mountain Dew soda. Are you a Mountain Dew addict? Then know what youre drinking! BVO is a toxic chemical that is banned in many countries because it competes with iodine for receptor sites in the body, which can lead to hypothyroidism, autoimmune disease, and cancer. The main ingredient, bromine, is a poisonous, corrosive chemical, linked to major organ system damage, birth defects, growth problems, schizophrenia, and hearing loss. Theres flame retardant in your Mountain Dew. That soda with the lime-green hue (and other citrus-flavored bubbly pops) wont keep your insides fireproof, but it does contain brominated vegetable oil, a patented flame retardant for plastics that has been banned in foods throughout Europe and in Japan. Brominated vegetable oil, or BVO, which acts as an emulsifier in citrus-flavored soda drinks, is found in about 10 percent of sodas sold in the U.S. After a few extreme soda binges not too far from what many [video] gamers regularly consume a few patients have needed medical attention for skin lesions, memory loss and nerve disorders, all symptoms of overexposure to bromine, according to a recent article in Environmental News. Origins: Brominated vegetable oil (BVO) is vegetable oil which is bonded with atoms of the element bromine. BVO has long been used as a food additive in the soft drink industry, primarily to help keep citrus-flavor oils suspended in beverages and prevent them from floating to the top of the fluid. BVO is commonly found in popular citrus-flavored soft drinks such as Mountain Dew, Squirt, Fresca, Sunkist Peach, and Fanta Orange, and also in sports drinks such as Powerade. The status of BVO differs in various parts of the world: It is allowed as a food additive in Latin American and North American countries (including the U.S. and Canada), but not in Japan or European Union countries. The U.S. Food and Drug Administration (FDA) originally classified BVO as a generally recognized as safe (GRAS) food additive in 1958, but that classification was withdrawn in the 1970s after studies linked the consumption of brominated oil with heart disease in rats. BVO was subsequently reclassified as an interim food additive (pending the outcome of additional studies), with the use of BVO in food products limited to a concentration of 15 ppm : Based on data from early studies, the FDA yanked brominated vegetable oil from its Generally Recognized as Safe (GRAS) list for flavor additives in 1970, said Douglas Karas, a spokesman for the FDA. BVO bounced back after studies from an industry group from 1971 to 1974 demonstrated a level of safety. The Flavor Extract Manufacturers Association petitioned the FDA to get BVO back in fruit-flavored beverages, this time as a stabilizer, which is its role today. After evaluating the petition and other data, the FDA in 1977 approved the interim use of BVO at 15 ppm in fruit-flavored beverages, pending the outcome of additional studies. This decision was based on the highest No Observed Effect Levels from the existing safety studies and the estimated daily intake, Karas said. Although there were doses that showed adverse effects in the animal studies, there also were lower doses in which there were no adverse effects observed. As a condition of interim approval, the industry group submitted additional safety studies to the FDA. The findings from these studies supported the safety of BVO in beverages at a level of 15 ppm in fruit-flavored beverages, Karas said. Its use as a flame retardant does not preclude its use as a food ingredient so long as the food use is safe. More than 30 years later, brominated vegetable oils approval status is still listed as interim. Changing the status would be costly and is not a public health priority for the agency at this time, Karas said. (Soft drinks which use BVO now typically contain about half the concentration allowed by law.) Recently, some scientists have called for a reexamination of BVOs safety as a food additive using newer technologies that were not available when the issue was last assessed by the FDA: Now some scientists have a renewed interest in this little-known ingredient, found in 10 percent of sodas in the United States. After a few extreme soda binges not too far from what many gamers regularly consume a few patients have needed medical attention for skin lesions, memory loss and nerve disorders, all symptoms of overexposure to bromine. Other studies suggest that BVO could be building up in human tissues, just like other brominated compounds such as flame retardants. In mouse studies, big doses caused reproductive and behavioral problems. Reports from an industry group helped the U.S. Food and Drug Administration establish in 1977 what it considers a safe limit for BVO in sodas. But some scientists say that limit is based on data that is thin and several decades old, and they insist that the chemical deserves a fresh look. Compounds like these that are in widespread use probably should be reexamined periodically with newer technologies to ensure that there arent effects that would have been missed by prior methods, said Charles Vorhees, a toxicologist at Cincinnati Childrens Hospital Medical Center, who studied BVOs neurological effects in the early 1980s. I think BVO is the kind of compound that probably warrants some reexamination. Michael Jacobson, executive director of the Center for Science in the Public Interest, was involved with the petition to remove BVO from the safe list in 1970. He said its time for the FDA to make a decision, one way or the other. Is it harmful at the amounts consumed? Probably not, Jacobson said. But it would be nice if the FDA did a thorough review of the literature and finalized an approval or a ban. A few medical cases involving patients who suffered deleterious effects due to excessive bromine levels in their systems have been attributed to consumption of soft drinks containing BVO: In 1997, doctors were stumped by the case of a man who came to the emergency room with headaches, fatigue, and a loss of muscle coordination and memory. He continued to get worse over time, and eventually he lost the ability to walk. A blood test found sky-high levels of bromide. The source? The man had been drinking between 2 and 4 liters of soda containing brominated vegetable oil every day. He needed dialysis but eventually recovered. In 2003, doctors treated a man who developed swollen hands with oozing sores. They diagnosed a rare case of the skin condition bromoderma after blood tests revealed his bromine was about twice normal limits. The man admitted drinking about 8 liters of Ruby Red Squirt, which contains BVO, each day. However, those cases involved subjects who drank what would generally be considered an excessive amount of soda on a regular basis (i.e., between two to eight liters daily). So far, no studies have conclusively documented serious health concerns in human beings caused by the consumption of moderate amounts of beverages containing BVO at the concentrations typically used in such products. Nonetheless, in January 2013 PepsiCo while acknowledging that they dont find a health and safety risk with BVO announced that in response to consumer concerns they would discontinue the use of BVO in their Gatorade line of drinks. The company stated at the time they had no plans to remove [BVO] from Mountain Dew and Diet Mountain Dew. However, in May 2014 PepsiCo reversed course and (along with Coca-Cola) announced they were working to remove BVO from all their drinks, including Mountain Dew, Fanta and Powerade.
