Quite a few years ago I wrote an article regarding the concept that 3 servings of low-fat dairy a day could help you lose weight. Then it was uncovered that the sponsor of the original study had ties to the dairy industry. Hmmm... makes you pause and think about how unbiased the study was, doesn't it? It's unfortunately the case with a lot of studies. Research is time consuming and expensive, so financial backing is necessary. Often, the finances come from an organization with a vested interest in the result. Any researcher worth his or her salt will perform an unbiased and accurate study regardless of the sponsor, however. And, if the sponsor wants accurate results, they should demand nothing less. Sometimes, however, the sponsorship of a study makes people question the results.

Such is the case with a 2006 study that determined lung scans might help save smokers from cancer. Big tobacco indirectly financed the study by making sizable donations (to the tune of 3.6 million) to a foundation that was listed as a sponsor of the study. Researchers properly revealed the study sponsors, but the indirect connection to big tobacco wasn't revealed. At this point, there is no indication that the study's findings are in any way tainted.
