The study analysed the effects of levels of fats and the risk of suicide. The study included 800 US military suicide deaths and 800 matched controls.
Regarding saturated fat, the study found that LOW levels of stearic acid (a saturated fat found in tallow (dripping), lard, beef and pork) were significantly associated with higher levels of suicide.
