Factlet of the Day

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.

Thank you!

We didn't know what to expect when we told you we needed to raise $400,000 before our fiscal year closed on June 30, and we're thrilled to report that our incredible community of readers contributed some $415,000 to help us keep charging as hard as we can during this crazy year.

You just sent an incredible message: that quality journalism doesn't have to answer to advertisers, billionaires, or hedge funds; that newsrooms can eke out an existence thanks primarily to the generosity of its readers. That's so powerful. Especially during what's been called a "media extinction event" when those looking to make a profit from the news pull back, the Mother Jones community steps in.

The months and years ahead won't be easy. Far from it. But there's no one we'd rather face the big challenges with than you, our committed and passionate readers, and our team of fearless reporters who show up every day.
