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.
