May 1, 2012 - New research claims there's a bias when it comes to publishing studies about autism drugs. An article in Pediatrics finds that positive results on serotonin receptor inhibitors, or SRI's are more likely to be published. The drugs are used to treat repetitive behaviors, which are a hallmark of autism. The authors found there were several unpublished studies that didn't show a significant benefit. The authors say the results of all completed trials should be disclosed, not just the positive ones.

Also, a new report from Harvard researchers estimates that deaths from cardiovascular disease could be reduced up to 3 percent if the food industry reduced salt content and salt products were taxed. A high salt intake has been linked to high blood pressure. Cardiovascular disease is the world's biggest killer, claiming about 17 million lives worldwide each year. The concept of taxing high-salt foods follows the taxing of junk foods that are high in trans fats, sugar and empty calories which are currently implemented in countries like Hungary and Denmark.
