Not that all food processing is bad. Skim milk and lean meat have been skimmed and trimmed of fat. Frozen vegetables are typically captured at peak ripeness without introduction of preservatives or sodium.
But many highly processed foods are stuffed with unpronounceable and nutritionally questionable substances. Add fat, sugar and salt, as processed foods so often do, Kessler said, and you have the perfect recipe for an American-style obesity epidemic.
“Twenty years ago, you would have maybe 20 to 30 chews per bite of food,” said Kessler. “Today, food is so highly processed and so stimulating it goes down in a wash (of saliva), like we’re eating adult baby food.”
