The food industry is skewing research, but we're onto them now

Oh, food, don't betray me too!

The food industry could be actively working against public health by influencing the results of studies in their favor.

New research reports that around 13.4% of the nutrition studies it analyzed disclosed ties to the food industry. Studies in which the industry was involved were more likely to produce results that were favorable to its interest, the team adds, raising questions in regards to the merits of these findings.

“This study found that the food industry is commonly involved in published research from leading nutrition journals. Where the food industry is involved, research findings are nearly six times more likely to be favourable to their interests than when there is no food industry involvement,” the authors note.

It’s not uncommon for industry to become involved with research — after all, they have a direct stake in furthering knowledge in their field of activity. This can range from offering funding to assigning employees to research teams for support or active research.

The current paper comes to show that, at least in the food industry, such activities are actively skewing and biasing research into nutrition. It is possible, the team reports, that this can put public health at risk as corporate interests can start dictating what findings see the light of day, where, and in what form. Such findings are worrying since corporations are notorious for putting profits above anything else, including truth or the common good.

In order to get a better idea of just how extensive the influence of industry is in food-related research, the team — led by Gary Sacks of Deakin University in Melbourne, Australia — analyzed all papers published in the top 10 peer-reviewed academic journals related to diet or nutrition. They looked at which had ties to the industry such as funding from food companies or affiliated organizations, and then whether or not the authors went out of their way to support industry interests.

Roughly 13.4% of the articles had some level of industry involvement, with some journals bearing more of the blame than others. The authors explain that studies with industry involvement were over five times more likely to favor industry interests compared to a random sample of studies without involvement (55.6% vs 9.7% for the latter).

Such figures offer a pretty big warning sign that industry involvement could promote research bias or help push an agenda at the expense of quality science (such as the neglect of topics that are important for public health but go against industrial interests). The authors suggest several mechanisms that could be employed to preserve the quality of nutrition research.

The paper “The characteristics and extent of food industry involvement in peer-reviewed research articles from 10 leading nutrition-related journals in 2018” has been published in the journal PLOS One.
