The objective of the study was to examine the association of stroke incidence with the intake of fat and type of fat among middle-aged men. The study included 832 men, aged 45 to 65 years who were followed for 20 years.

 

The study found:

(a) For every 3% increase in fat consumption the men had a 15% reduced risk of stroke.

(b) For every 1% increase in saturated fat consumption the men had a 9% reduced risk of stroke.

 

The study reveals that total fat and saturated fat consumption are associated with a reduced risk of stroke in men.

The study examined the relationship between intakes of saturated fat and animal protein and the risk of intraparenchymal hemorrhage. (An intraparenchymal hemorrhage is a type of stroke where bleeding occurs within the brain tissue). The study lasted for 14 years and included 4,775 participants aged 40-69 years.

The study found:
(a) Those who consumed the most fat had a 54% reduced risk of intraparenchymal hemorrhage compared to those who consumed the least fat.
(b) Those who consumed the most saturated fat had a 70% reduced risk of intraparenchymal hemorrhage compared to those who consumed the least saturated fat.
(c) Those who consumed the most cholesterol had a 29% reduced risk of intraparenchymal hemorrhage compared to those who consumed the least cholesterol.
(d) Those who consumed the most animal protein had a 40% reduced risk of intraparenchymal hemorrhage compared to those who consumed the least animal protein.

The results of the study show that a high consumption of saturated fat and foods of animal origin reduce the risk of intraparenchymal hemorrhage.
