Corporate funded nutrition researches are biased

After examing 206 scientific papers on the health effects of soft drinks, fruit juice and milk (111 of which declared their funding source), researchers at Children's Hospital in Boston (US) found that industry-backed papers are 7 times more likely to produce a conclusion favoring a company's product. The reasons for the bias may include a failure to publish unfavorablele findings, or a tendency of firms to back only studies that are likely to present their products in a positive light.
