I should correct that to say "LOW" instead of "very LOW." While Inuit total
cholesterol was much lower than the Danish figure, in the Bang/Dyerberg
study it was slightly higher than the top of the recommended clinical range
(208 mg/dl Inuit vs. 243 mg/dl Danes vs. 200 mg/dl clinically recommended
maximum). However, this is a little misleading, as the very high HDL ("good"
cholesterol) levels of the Inuit skew the total cholesterol up, so that
total cholesterol is not a very useful figure. It is clearer to say that the
Inuit had much lower levels of triglycerides and LDL and much higher levels
of HDL than the Danes.
