This study investigated the relationship of dietary intakes to subsequent development of coronary heart disease. The study lasted for six years and included 7,705 men, aged 45 to 68.
Regarding saturated fat consumption, the study found:
(a) Men who died from heart disease consumed 3.1% less saturated fat compared to men who remained free from heart disease.
(b) Men who developed coronary insufficiency consumed 6.2% less saturated fat compared to men who remained free from heart disease. (Coronary insufficiency is an inadequate blood flow to the heart muscles).
(c) Men who developed angina consumed 3.1% less saturated fat compared to men who remained free from heart disease.
