No
One "Perfect Diet"
Any
claim of a common perfect diet for all people doesn't take into account
the huge variety of geography that separate humans and always has. The
tropics enjoy beautiful varieties of foods all year long, while the
moderate climates have seasons where nothing is available, unless our
ancestors knew how to store for the winter. Variety wasn't even a
fantasy.
The more northern climes learned to dry, smoke, cook and preserve both
animal and vegetable products so that starvation wouldn't descend during
the cold dark foodless winters.
In the case of the Inuit Eskimo of the FAR north, they ate their seal
meat and blubbers raw in general, which lent itself to their dietary
needs, heat retention and the fact that this food source was available
all year long.
With the varied climes, you also see varied needs. The people of the
tropics had coconut oils to sooth their skin and keep long tanned skin
soft and supple in their diet.
The people of the north had windblown dry skin and the animal fats in
their food helped to keep cracks and rashes at bay.
The hair and teeth, bone structure and build, all lend to the climates
of origin and the foods found there.
