What the research says

1 study
  1. Study: Associations of Dietary Fat Intake With Mortality From All Causes, Cardiovascular Disease, and Cancer: A Prospective Study

    The study found that eating more saturated fat was linked to higher risk of death, while more polyunsaturated and monounsaturated fats were linked to lower risk. This goes against the claim that a diet with 25% of fat as saturated fat is healthy.
