An anonymous reader quotes a report from The Verge: About 50 years ago, the sugar industry stopped funding research that began to show something they wanted to hide: that eating lots of sugar is linked to heart disease. A new study exposes the sugar industry's decades-old effort to stifle that critical research. Researchers at the University of California, San Francisco, recently analyzed historical documents regarding a rat study called Project 259 that was launched in 1968. The study was funded by a sugar industry trade group called the International Sugar Research Foundation, or ISRF, and conducted by W. F. R. Pover at the University of Birmingham. When the preliminary findings from that study began to show that eating lots of sugar might be associated with heart disease, and even bladder cancer, the ISRF pulled the plug on the research. Without additional funding, the study was terminated and the results were never published, according to a study published today in PLOS Biology. The study in question investigated the relationship between sugars and certain blood fats called triglycerides, which increase the risk of heart disease. The preliminary results from the research, called Project 259, suggested that rats on a high-sugar diet, instead of a starch diet, had higher levels of triglycerides. The rats that ate lots of sugar also had higher levels of an enzyme called beta-glucuronidase in their urine, which at the time was thought to be potentially linked to bladder cancer, says study co-author Cristin Kearns, an assistant professor at the UCSF School of Dentistry.
