In June, Dr. Barbara Bowman, a high-ranking official within the Centers for Disease Control and Prevention, unexpectedly departed the agency, two days after information came to light indicating that she had been communicating regularly with – and offering guidance to – a leading Coca-Cola advocate seeking to influence world health authorities on sugar and beverage policy matters.

Now, more emails suggest that another veteran CDC official has similarly close ties to the global soft drink giant. Michael Pratt, Senior Advisor for Global Health in the National Center for Chronic Disease Prevention and Health Promotion at the CDC, has a history of promoting and helping lead research funded by Coca-Cola. Pratt also works closely with the nonprofit corporate interest group set up by Coca-Cola called the International Life Sciences Institute (ILSI), emails obtained through Freedom of Information requests show.

Pratt did not respond to questions about his work, which includes a position as a professor at Emory University, a private research university in Atlanta that has received millions of dollars from the Coca-Cola Foundation and more than $100 million from famed longtime Coca-Cola leader Robert W. Woodruff and Woodruff’s brother George. Indeed, Coca-Cola’s financial support for Emory is so strong that the university states on its website that “it’s unofficially considered poor school spirit to drink other soda brands on campus.”
