Scientist Who Discredited Meat Guidelines Didn’t Report Past Food Industry Ties

A surprising new study challenged decades of nutrition advice and gave consumers the green light to eat more red and processed meat. But what the study didn’t say is that its lead author has past research ties to the meat and food industry.
The new report, published this week in the Annals of Internal Medicine, stunned scientists and public health officials because it contradicted longstanding nutrition guidelines about limiting consumption of red and processed meats. The analysis, led by Bradley C. Johnston, an epidemiologist at Dalhousie University in Canada, and more than a dozen researchers concluded that warnings linking meat consumption to heart disease and cancer are not backed by strong scientific evidence.
Several prominent nutrition scientists and health organizations criticized the study’s methods and findings. But Dr. Johnston and his colleagues defended the work, saying it relied on the highest standards of scientific evidence, and noted that the large team of investigators reported no conflicts of interest and conducted the review without outside funding.
Dr. Johnston also indicated on a disclosure form that he did not have any conflicts of interest to report during the past three years. But as recently as December 2016 he was the senior author on a similar study that tried to discredit international health guidelines advising people to eat less sugar. That study, which also appeared in the Annals of Internal Medicine, was paid for by the International Life Sciences Institute, or ILSI, an industry trade group largely supported by agribusiness, food and pharmaceutical companies and whose members have included McDonald’s, Coca-Cola, PepsiCo and Cargill, one of the largest beef processors in North America. The industry group, founded by a top Coca-Cola executive four decades ago, has long been accused by the World Health Organization and others of trying to undermine public health recommendations to advance the interests of its corporate members.
