Some perspective, via Wrangham's Catching Fire:
- "In the US, children from 9 to 12 years of age spend a mere 10% of their time eating, or just over an hour per 12-hour day." (72 minutes)
- In 12 subsistence societies around the world, children aged 6 to 15 chewed about 7-8% of the day, adults about 5%. (Children: 54 minutes, Adults: 36 minutes)
- By contrast, Tanzanian chimpanzees spend more than 50% of their waking hours chewing, roughly 6 hours to consume about 1800 calories. (360 minutes)
- Wrangham asked, "How long would humans be obliged to spend chewing if we lived on the same kind of raw food that great apes do? ... Conservatively it would be 42% of the day, or just over 5 hours of chewing in a 12-hour day." (302 minutes)
"When eating muscle, chimpanzees are forced to chew it slowly ("their teeth cannot cut meat easily, their mouths are relatively small, their stomachs do not process hunks of raw meat efficiently"), taking as much as an hour to chew one-third of a kilogram (three-quarters of a pound)"This puts the raw food, vegan Evo Diet into better perspective. It may be effective for weight loss, but it's probably not the diet humans evolved to eat.
