Tyler Cowen passes along the news that Americans used to chew their food 25 times before swallowing, but today the average is down to ten chews.  Interesting!  But how do we know this?  Has it been measured?  Here’s the original source for the claim:

The modern American diet is mostly made up of “easy calories.”  According to Gail Civille, a food-industry consultant and the owner of Sensory Spectrum, Americans of the past typically had to chew a mouthful of food as many as 25 times before swallowing; the average American today chews only 10 times.

In part, this is because fat, which has become ubuiquitous, is a lubricant. We don’t eat as much lean meat, which requires more saliva to ready it for swallowing.  “We want food that’s higher in fat, marbled, so when you eat it, it melts in your mouth,” says Civille.  Food is easier to eat when it breaks down more quickly in the mouth.  “If I have fat in there, I just chew it up and — whoosh! — away it goes.”

John Haywood, a prominent restaurant concept designer, agrees.  Processing, he says, creates a sort of “adult baby food.”  By processing, he means removing the elements in whole food — like fiber and gristle — that are harder to chew and swallow.

Hmmm.  That’s certainly plausible, but I still want to know where those exact figures come from.  I demand proof.

DEMOCRACY DOES NOT EXIST...

without free and fair elections, a vigorous free press, and engaged citizens to reclaim power from those who abuse it.

In this election year unlike any other—against a backdrop of a pandemic, an economic crisis, racial reckoning, and so much daily crazy—Mother Jones' journalism is driven by one simple question: Will America will move closer to, or further from, justice and equity in the years to come?
