The Sugar Industry's Harvard Study Cover-Up (1960s)

Internal industry documents leaked in 2016 proved that the Sugar Research Foundation paid Harvard scientists $50,000 (equivalent to nearly $500,000 today) to publish a 1967 review absolving sugar of any role in coronary heart disease and incriminating dietary fat instead. This manufactured consensus directly influenced the 1977 U.S. Dietary Goals, which advised Americans to reduce fat consumption—triggering a subsequent 30% rise in added sugar intake per capita by 2000. The deception is more insidious than the IARC's red meat classification (#8) because it was a deliberate corruption of science, not an overstatement of observational data. Independent re-analyses of the original 1960s trials now show that sugar consumption correlates with a 35% higher risk of heart disease, a finding the industry actively suppressed.
