Is there a relation between the eating patterns of the inuit and the prevalence of cardiovascular disease?

Changing fast... The native inuit diet (eastern canadian artic to siberia) was completely animal based. No vegetation. No heart disease, obesity, diabetes, dental carries, etc. However, i know from personal experience, working at a hospital in frobisher bay on baffin island for six weeks, that their diet has irrevocably been altered by "down south" diets, typical of montreal and toronto & now get southern ills.
