CHAPTER EIGHT

The Science of Addictive Food

NESTLÉ NEVER CLAIMED to be a health company, but it did claim to be a science company.

Its research division, the Nestlé Research Center in Lausanne, Switzerland, has employed hundreds of scientists, nutritionists, chemists, and food engineers. On paper, their goal was simple: understand how food works in the body and how to make it better.

But “better” doesn’t always mean healthier.

Sometimes it means more desirable. More cravable. More profitable.

That’s where the science came in.

By the late 20th century, food companies had figured out how to engineer flavor. Not just taste, but response. They discovered the role of sugar, salt, and fat in triggering dopamine. They tested mouthfeel, crunch profiles, melting rates, and aftertaste curves. They mapped what came to be known as the “bliss point,” the exact combination of sweetness, saltiness, and texture that would make people want more.

Nestlé was part of that movement.

It ran trials, built flavor databases, conducted consumer testing, and used brain imaging and sensory labs to see how people reacted not just physically, but psychologically. It wasn’t doing anything illegal, but it was doing something important:

Designing food not just to satisfy hunger, but to bypass it.

When people say a snack is “addictive,” they’re often joking. But the science behind it isn’t. Hyperprocessed foods, the kind Nestlé specializes in, are made to override satiety signals. You’re not supposed to stop after one bite. You’re supposed to keep going. That’s the point.

And it worked.

Nestlé’s top-selling products, KitKat, Maggi noodles, Nescafé creamers, flavored waters, ice creams, powdered cocoa, and frozen pizzas, they’ve all relied on this principle. Not just being tasty, but being reliable. Something your brain remembered and wanted again.

Critics compared it to the tobacco model: fund research, deny harm, sell the hook. That’s a stretch. But not by much.

Nestlé didn’t create human cravings, but it certainly learned how to feed them.

And once that loop of craving, consumption, profit was built, it never broke it.
