gfpaperdol, I think it's great that you know so much about your ancestors, and the food you were eating on your trip to the Canadian artic sounds wonderful! I'm not at all sure about my ancestry. I had an Irish mother and English father, but their ancestors could have originated anywhere. I decided to invent an ancestry that used to eat like this....
Plenty of fatty meat, fish, poultry, eggs
Plenty of green and colorful vegetables
Limited access to fruit, mostly berries
Limited access to coffee, tea, butter, cheese and cream
No access to grains or starchy tubers
No access to sugar
Occasional access to fermented fruit (which I like to call wine)
Occasional access to cocoa (which I like to call 90% chocolate)
I also don't know in what era these mythical ancestors existed, but since I discovered their w.o.e. 18 months ago it has improved my health and weight more than I ever dreamed possible. I choose to call it Primal, although obviously other people may have very different ideas of what Primal means to them.
