The study investigated the risk factors for, and the rates of heart disease deaths in northernmost Finland compared with southern areas of Finland. The study lasted for nine years and included 350 participants, average age 46 years.
The study found:
(a) The death rates from heart disease were 17% lower in northernmost Finland compared with southern areas of Finland.
(b) Cholesterol levels were 6.3% higher in northernmost Finland compared with southern areas of Finland.
(c) Low density lipoprotein (LDL) cholesterol levels were 7.0% higher in northernmost Finland compared with southern areas of Finland.
(d) Vitamin E levels were 14.2% higher in northernmost Finland compared with southern areas of Finland.
(e) Vitamin E levels increased with the consumption of reindeer meat.
The results of the study show that higher cholesterol levels and higher meat consumption are associated with decreased rates of heart disease deaths.
