This study investigated the association of saturated fat and animal protein with the risk of intraparenchymal (bleeding in the superficial surface of the brain) hemorrhage. The study included 85,764 women, aged 34 to 59 years, who were followed for a total of 1.16 million person-years.
The study found:
(a) Women who consumed the most saturated fat had a 27% reduced risk of intraparenchymal haemorrhage compared to women who consumed the least saturated fat.
(b) Women who consumed the most animal protein had a 53% reduced risk of intraparenchymal haemorrhage compared to women who consumed the least animal protein.
Iso concluded: "Low intake of saturated fat and animal protein was associated with an increased risk of intraparenchymal haemorrhage."
