Fluoride in pet food: The link to osteosarcoma
PAW PRINTS: Fluoride in pet food: The link to osteosarcoma
By Niki Laviolette Special to the Tribune-Star TERRE HAUTE — The most common type of bone cancer in dogs, cats and humans is osteosarcoma. Osteosarcoma is more common in the larger breeds of dogs such as Rottweilers, greyhounds, golden retrievers, etc. Eighty-five percent of all major bone tumors in dogs and 70 percent in cats are osteosarcoma. Approximately 5 percent of all primary bone tumors in children are osteosarcoma-related. A number of studies suggest a possible link between osteosarcoma and the exposure to fluoride. According to the Environmental Working Group (www.ewg.org), they “conclude that fluoridation of public water supplies should stop because of risks that outweigh the possible benefits, especially for infants and young children who consume more water than adults, relative to their size.” The Environmental Working Group has been concerned with healthy ingredients and the safety of pet food. EWG pet food testing has revealed high levels of fluoride in various major brand pet foods. Veterinarians are reporting a rise in cancer rates found in dogs and many are wondering if diet is a contributing factor. George Glasser, press officer/water quality adviser, National Pure Water Association, reports, “A low-fluoride commercial dog food contains 40-60 parts per million of fluoride. A high-fluoride dog food can contain up to 460 parts per million of fluoride.” A study at the University of Montana indicated the average level of fluoride in leading pet foods to be 11 to 193 ppm, with canned food having the highest amount. The Montana researchers discovered that fluoride accumulates in pets’ bones. 84 to 1,535 milligrams of fluoride was found in the leg bones of dogs. 74 to 1,190 milligrams was found in cat bones, and it increased with age. A number of lower-grade dog foods may contain up to 2,000 ppm of fluoride. The government daily limit said to be safe for children over 3 years of age is 2.5 milligrams. Tolerance levels have been identified for domesticated animals, with the lowest values for dairy cattle at 30 mg/kg feed or 2.5 mg/liter drinking water. Numerous research has been done on sheep, pigs, goats, cattle and chickens on adverse health effects from fluoride, with little information relating to cats and dogs. “Consequently, it is safe to assume that many of dogs and cats who appear to be suffering with arthritis, dysplasia, spinal deformities, etc., may have actually developed skeletal fluorosis.” Even though a particular breed may be genetically predisposed to such health problems, fluoride in pet food could prematurely trigger the disease. “The primary source of the fluoride in pet foods is from the added mineral supplements: defluorinated phosphate rock, raw soft phosphate rock, mono and tricalcium phosphate. The less expensive the dog food, probably the higher the fluoride levels because they use raw phosphate. Raw phosphate, mainly because of its fluoride content (3 to 4 percent), is the most physically damaging animal mineral supplement because it is not processed and is the least-expensive. These facts have been known since the 1920s in early animal nutritional research of fluorine in animal nutrition. http://www.tribstar.com/valley_life/...164204633.html |

Yeah, cancer is real funny. http://www.onlinelawyersource.com/fl...oma/index.html Biological and physical evidence have led health officials to determine a link between fluoride and bone cancer . Fluoride, once thought to have health benefits, shows evidence of severe, long-term bodily health effects. The link is most evident in cases of osteosarcoma cancer in children who have been exposed to elevated amounts of fluoride during childhood. Fluoride and bone cancer have been inextricably linked due to biological factors regarding fluoride build-up in bones. Fluoride accumulates in the bones and can cause cancerous growths during the developmental phase. While osteosarcoma can occur in both boys and girls, osteosarcoma as a result of fluoride exposure is much more prevalent in young boys. http://www.fluoridealert.org/health/...eosarcoma.html As acknowledged by the U.S. National Toxicology Program there is a "biological plausibility" of a link between fluoride exposure and osteosarcoma. The biological plausibility centers around three facts: 1) Bone is the principal site of fluoride accumulation, particularly during the growth spurts of childhood; 2) Fluoride is a mutagen when present at sufficient concentrations, and 3) Fluoride can artificially stimulate the proliferation of bone cells (osteoblasts). In addition to its biological plausibility, there is now a substantive body of evidence indicating that fluoride can in fact induce osteosarcomas in both animals and humans. Most notably, a recent national case control study conducted by scientists at Harvard University found a significant relationship between fluoride exposure and osteosarcoma among boys, particularly if exposed to fluoridated water between the ages of 6 and 8 (the mid-childhood growth spurt). The Harvard study's findings are consistent with the U.S. National Toxicology Program's congressionally-mandated fluoride/cancer study in rats; the National Cancer Institute's 1990 analysis of osteosarcoma rates among young males in fluoridated versus unfluoridated areas in the U.S., and the New Jersey Department of Health's 1992 analysis of osteosarcoma rates among young males in fluoridated versus unfluoridated areas of Central New Jersey. In addition, two later independent analyses of NCI's national cancer data also found a relationship between fluoridation and osteosarcoma among young males (Yiamouyiannis 1993; Takahashi 2001). Taken together as a whole, the evidence - laboratory, animal, and human - suggests that fluoride could either directly initiate, or contribute to, the development of osteosarcoma in boys under the age of 20. http://www.fluoridealert.org/health/...-timeline.html This link is the most disturbing because it shows that the US Congress asked for studies on this way back in 1997. A lot of people and pets have died from this since then! |

Yeah, cancer is real funny. Do you really believe all that crap just because someone posted it on the internet? You do realize I could make a real name seeming site on the same theme and say feed your dog green beans and it's excellent for them? Excite a grey cell by letting it exercise for a moment next time you read one of those sites. |
