Mixed

Scientific articles regarding the health effects of soft drinks, juice, and milk that are funded exclusively by the food/beverage industry are significantly more likely to conclude favorably for the sponsor's product compared to articles with no industry funding.

When evaluating health claims about soft drinks, juice, or milk, prioritize research that did not receive funding from the beverage industry. Industry-funded studies are significantly more likely to report favorable health outcomes for the sponsored product, suggesting a high risk of sponsorship bias.

GoodSupportsHIGH confidence
The main finding of this study is that scientific articles about commonly consumed beverages funded entirely by industry were approximately four to eight times more likely to be favorable to the financial interests of the sponsors than articles without industry-related funding.
