"Eskimo" - from "Eskimantsik" - means "eater of raw meat."

Macronutrients - carbohydrates, fats, alcohol, and proteins - are the sources of all dietary calories. These are the compounds that are converted into energy.
Micronutrients - generally vitamins and minerals - although needed only in trace amounts, are essential for survival.
A visitor to the arctic attempted to become infected with tapeworms from eating raw Arctic char. He removed tapeworm larvae from the fish, and swallowed them in gelatin capsules. He developed three tapeworms from 24 larvae. He then recommended that the fish be cooked to kill the larvae - not realizing that cooking would destroy vitamin B12, the only source of vitamin B available.
Since every animal in the arctic food chain is eating the other raw, the nutrients are preserved, and passed on up the food chain to its pinnacle.

The replenishing of nutrients improves health.
The perception of improved health may be experienced immediately.
Most cultures have or had mythologies, rituals, and/or religious ceremonies involving the eating of raw flesh.
It is obvious that a source of the superstitions is a combination of pride and excitement in successful hunting and the relative perception between exhausted nutrition and the sudden onset of an overwhelming sense of health.
