Theranos founder Elizabeth Holmes tried to keep secret both her food preferences and her intimate relationship with company president Sunny Balwani, according to an interview with her personal assistant detailed in an FBI report filed in court in connection with Holmes’ criminal fraud trial.

“Holmes was very private,” the assistant, Paige Williams, who worked for Holmes from June 2015 to July 2018,  told the FBI. “Sensitive items included Holmes’ food preferences.” Shopping lists for Holmes’ food at home and work were “kept private” because “she was vegan for a period and did not want it to be made a big deal,” according to the FBI report.
