yudkin’s failure to incorporate possible confounding factors in his case-control designs was an area of heavy criticism at the time; apart from other unmeasured known risk factors that might affect cardiovascular disease (cvd), data had emerged soon after, suggesting that sugar intake was associated with smoking, a big risk factor for cvd. yudkin’s failure to account for confounding factors led to harsh words from ancel keys at the time. from the late 2000s, there was a resurgence of interest in his work, following a 2009 "youtube" video about sugar and high-fructose corn syrup by the pediatric endocrinologist robert lustig, and because of increasing concern about an obesity epidemic and metabolic syndrome. "pure, white and deadly" was republished in 2012, with a foreword by lustig.
