As reported by Sina Media, in this scientific journal club a study, conducted on a cohort of over 400,000 American adults which investigated the association between dietary intake of plant and animal fats and their sources with mortality risk was discussed. Results indicated that higher intakes of plant fats were linked to a reduced risk of all-cause and cardiovascular mortality, while higher intakes of animal fats were associated with increased risks of all-cause and cardiovascular mortality. Notably, the inverse association was particularly significant for plant fats derived from grains and vegetable oils. Moreover, the direct association observed between animal fat and mortality risk remained significant for fats from eggs and dairy products. Replacing animal fat sources with plant fat sources resulted in a significant inverse association with mortality risk for every 5% of energy derived from plant fats.

In conclusion, this study demonstrated an inverse association between higher intakes of plant fats and mortality risk, and a direct association between higher intakes of animal fats and mortality risk.
